Maximizing the Value
of Your Purchase
Congratulations on choosing a superb product. Your Proceed PAV is designed to
give you many years of outstanding performance, and we are confident you will
be happy with it.
We value our relationship with our customers, and often are in a position to help
you enjoy your home entertainment system even more—if we have some way of
contacting you.
Send in that warranty card!
Sending in your warranty card registers your product with us so that warranty
service in the U.S. and Canada (see the warranty policy on page 70) can be obtained easily and quickly even if you have lost your original sales slip. (And how
many of us are organized enough to retain all those sales slips?) Moreover, sending in the card automatically extends the warranty from 90 days to five years, at
no cost to you. Please send it in soon, before you forget.
But there are even more benefits to sending in your registration card, including
services for people outside the U.S. and Canada.
✓ software update notices
✓ performance upgrade notices
✓ free subscription to Madrigal’s QuarterNotes newsletter
We have occasionally offered software updates to our products that provide new
features and control options (for example, to facilitate their inclusion in custom
installations, or that automate customer preferences to greater degrees than previous software versions). These updates are generally a matter of changing out a
socketed EPROM. If they include features you would like to have, you can get
them—if you know about them.
We also try to offer performance upgrades and/or conversions to make upgrading
within a family of products as cost-effective as possible for our customers. For
example, people who already owned the Proceed DAP digital processor when
the HDCD process became available were able to upgrade their unit to HDCD™
for an extremely nominal price. While not all upgrades can be inexpensive, they
all represent excellent values—if you know about them.
One of the best ways we have of communicating with the large number of customers we have around the world is through our company newsletter,
QuarterNotes. This newsletter contains information on industry developments,
new products, software updates and upgrades, as well as general interest articles
on recommended music and movies, and occasional profiles of customers and
industry personalities. QuarterNotes is a service we provide to help keep open
our lines of communication with our customers, and it is free—if we know
where to send them.
So please, take a few minutes to fill out the warranty
registration card, and drop it in the mail.

Unpacking and Placement
Unpacking
Unpack your Proceed® PAV audio video preamplifier and keep all packing materials for future transport. Locate and remove all accessory items from the
cartons. Accessories include:
1 AC power cord
1 PAV remote control
4 alkaline batteries for the remote control
Important!
Installing Batteries in
the Remote Control
Placement
Your PAV has been shipped with software pre-installed that
enables it to work seamlessly with a Proceed PDSD as part of
a high performance, two-piece multichannel controller. If you
need to use the PAV by itself (without a PDSD), your dealer
must install the enclosed EPROM found in a small black antistatic box. Do not attempt to install this yourself, as only
qualified technicians may open the unit without voiding the
warranty!
Turn the remote control over and slide the battery compartment cover up and
away from the body of the remote. Insert the four alkaline batteries found in the
Accessories kit, being careful to follow the polarity indications given on the inside
of the battery compartment. Replace the battery cover.
Place the PAV near the source equipment, thus keeping interconnecting cables
reasonably short. It may be placed on a shelf or in a cabinet where it’s convenient to operate.
Note that adequate clearance for the AC cord and connecting
cables must be left behind the PAV. We suggest leaving at least
three inches of free space behind the PAV to allow all cables
sufficient room to bend without crimping or undue strain.
Ventilation
It is normal for your PAV to run quite warm. Be sure to allow 2 to 3 inches of
clearance above the PAV to allow heat dissipation through air circulation. The
vents on both the bottom and the top of the PAV must be kept free from any obstruction which would reduce the flow of air through the unit. The best rule of
thumb is this: if the top of your PAV is too hot to touch, it needs better ventilation. If so, consider drilling holes in the supporting shelf under the PAV to promote flow-through ventilation, or use fans to increase air circulation. Avoid placement on soft surfaces that would restrict airflow (such as carpeting).
Mechanical drawings are included in this manual to facilitate special installations
and custom cabinet work (see “Dimensions” at the end of this manual).
8
Operating Voltage
The PAV preamplifier is factory-set for 100V, 120V, 200V, 220V, or 240V AC mains
operation at either 50 or 60Hz, according to the country for which the unit was
manufactured. (230V only in European Union countries, in compliance with CE
regulations.) Make sure that the label on the bottom of the PAV indicates the correct AC operating voltage for your location. The operating voltage cannot be
changed by the user, and any attempt to do so will void the warranty.
If the voltage indicated does not match what is supplied to your area, see your
Proceed dealer.
9
A Word About Installation
Every effort has been made to make the Proceed PAV simple and straightforward
to install and use. We also know of no other product which offers this level of
performance and flexibility. Still, we have no way to evaluate many other variables
such as the size and shape of your room, its acoustics, and the associated equipment you have chosen to use with your PAV. All of these factors influence the ultimate performance of your system. Moreover, the PAV incorporates many systemspecific adjustments which enhance its performance with the widest possible
range of associated components.
For this reason, we strongly encourage you to have your
system installed and calibrated by your dealer, whose
experience, training, and specialized equipment can make a
profound difference in the final performance of the system.
The PAV features the ability to “remember” the carefully calibrated settings chosen
by your installer. You may adjust any or all of these settings to suit your taste for
a particular recording, either from the front panel or from the remote control.
When you want to return to the calibrated settings (which most accurately reproduce the widest variety of program material), simply press recall on the remote
control or on the front panel.
10
Home Theater and
the Proceed PAV
Perhaps the most exciting development in home entertainment in recent years is
the much-discussed “marriage of audio and video.” Movies are available in high
quality formats such as laserdisc, and big-screen televisions have improved vastly
over the dim, fuzzy pictures many people remember from a few years ago. Combined with sound reproduced via several loudspeakers and (perhaps) a
subwoofer, it has become possible to have movie excitement in the home which
far exceeds that available in most local theaters.
Unfortunately, many people found these “home theaters” sadly lacking when it
came to their performance with more traditional music sources. Although some
were capable of shaking the walls with explosions and sound effects, few were
capable of reproducing the nuances of a string quartet, a big band, or a well-recorded vocalist.
The Proceed PAV is designed for people (like ourselves) who desire to “have it
all.” The PAV offers the musical refinement, control flexibility and movie excitement of both a dedicated high end music system and a full-blown home theater
system, all in one simple package. With its introduction, there is no longer a need
to compromise on either music or movies. A single system can do it all.

Listening Room
Movie Sound and the PAV
Unlike traditional stereo sources, Dolby Stereo™ movie soundtracks contain four
channels: Left, Center, Right and Surround. The three speakers in the front of the
room (L, C, and R) provide precise localization of sounds, or imaging, while the
surround channel is intended to be reproduced in a diffuse manner to the sides
and behind the audience—to literally “surround” that person in the ambient
sounds of the environment shown on the screen. Normally, a correctly operating
Surround channel would be so diffuse and enveloping as to be almost subliminal. Its purpose, after all, is to draw you into the movie, not to distract you from
it.
11
Dolby Pro Logic™ Sources
The PAV accurately decodes the Dolby Stereo™ soundtracks available in virtually
all modern film soundtracks, many television shows, and even some music recordings. It does so by employing carefully optimized Dolby Pro Logic circuitry,
for superior performance and accuracy. Use the pro logic mode whenever listening to most surround-encoded television shows, MTV (most of which is now surround encoded), and other surround-encoded program material which has been
created for general distribution.
THX Cinema Sources
In addition, the PAV incorporates Home THX® audio processing to help movie
soundtracks make the transition from large movie theaters into the home. This
extra step is necessary because the acoustics of movie theaters and living rooms
are so different. Some adjustments are necessary in order to achieve the same
subjective effect in your home as in the finest movie auditoriums. These “adjustments” are precisely what Home THX offers. Use the THX cinema mode for
Dolby Stereo movies which were created for theatrical release—meaning virtually
all movies made since the late 1970’s.
Music and the PAV
When it is time to enjoy some of your favorite music, the PAV gives you several
simple options, any of which may be selected by pressing the mode button to
cycle through the choices.
The stereo surround mode uses ambient cues contained in your normal stereo
recordings to create a realistic, full-bodied soundfield using all available speakers.
It has been carefully tuned to enhance stereo playback, and can be expected to
be relatively subtle rather than dramatic. (As with attending a live concert, one’s
attention should rarely be called to the characteristic sound of the “hall.” The
acoustics of the space in which the music is performed should enhance the musical experience without becoming an end unto themselves.)
The mono surround mode can be used to give acoustically “dry” mono recordings a sense of spaciousness. This mode can be used for historical monophonic
music recordings as well as for older movie classics which were recorded in
mono. This mode is particularly helpful when watching older, mono movies on a
big-screen television, where the disparity between aural and the visual size would
otherwise be a distraction to the movie experience.
The surround off mode returns your system to two-channel stereo.
Finally, we have provided a “true mono” mode which reproduces both the Left
and the Right signals through the center channel speaker (and subwoofer) only.
The mono mode is sometimes desirable when listening to noisy monophonic
music recordings or movie soundtracks. Since noise tends to be random in nature, much of it cancels out when L+R are mixed together, as they are in this
mode.
Subwoofers and
Surround Modes
12
If a subwoofer is connected to the sub outputs, it will normally be given the
deepest bass (below 80 Hz) at all times, independantly of the surround mode or
input selected. Whether or not the three front speakers are also given the deepest
bass information (below 80 Hz) to reproduce is determined by the settings of
the set speakers menu during setup. (See System Setup & Calibration for more
information).

VIDEO SOURCE SELECTION BUTTONS
These four buttons select both the video and associated audio signals from
any of the four A/V inputs. To use these Selection Buttons, choose the appropriate path (see path, below). (For your music/home theater room,
“main” would be appropriate.) Then make your selection. The sophisticated
switching system employed in the PAV allows simultaneous, independent
routing of both audio and video signals along any or all of three paths:
main, remote and record.
2
AUDIO SOURCE SELECTION BUTTONS
These six buttons select audio signals from among the six audio-only
inputs. (Note that both cd1 and bal/aux are balanced inputs which use
precision XLR connectors.) To use these selection buttons, choose the appropriate path (see path, below), and then make your selection.
Selecting any audio source after having selected a video source will cause
the newly-selected audio signal to “override” the audio portion of the video
selection (leaving the video signal unaffected). Thus, to enjoy a simulcast,
merely select the desired picture followed by the desired sound. To revert
to the sound of the video input, just press the video input button again.
Viewing Simulcasts
3
MAIN DISPLAY
The main display provides information pertaining to the operation of the
PAV including relative volume levels, and is used in conjunction with the
buttons which surround it. At all volumes above a relatively quiet background level, and in all modes, the volume control enjoys a resolution of 0.5
dB. Thus a change of 10 decibels would be indicated by a change of 20 in
the display.
13
The main display indicates the master volume by default, or the following
offsets when chosen: balance, center, rear, subwoofer. In addition, it can also
display the input level (used in calibrating the Dolby Pro Logic circuitry to
the source material) and the rear channel delay (in milliseconds). Rightand Left-facing arrows are provided to indicate the direction of the balance
offset. Finally, the infrared receiver and transmitter for the remote control are
positioned on the left side of the main display.
14
4
VOLUME +/–
These up/down buttons are used to make adjustments on the PAV, apart
from source and path selection. While the volume +/– buttons normally
control the master volume of the music/home theater system (main path),
they can be used in concert with other buttons to control almost any aspect of system performance (as indicated below).
5
MASTER
When the indicator above this button is lit, any adjustment made with the
volume +/– buttons will be applied to all loudspeakers equally, including
Center, Rears, and Subwoofer(s), thus raising or lowering the overall volume
without changing the relative balance of the various speakers. This is the
default mode of operation for the volume control, to which the PAV automatically returns after you make other adjustments.
6
BALANCE
Pressing this button followed by the volume +/– buttons will alter the relative volume of the Front Left and Front Right speakers. The direction of the
perceived image shift is indicated by the green arrowhead indicators in the
main display, as well as by the on screen display. Pressing volume + in the
balance mode will shift the image to the right (in a “positive” direction);
pressing volume – will shift the image to the left (in a “negative” direction).
7
CENTER
Pressing this button followed by the volume +/– buttons will alter the volume of the Center speaker relative to all others. The resulting offset will be
indicated in the main display, as well as by the on screen display, until the
volume control reverts to its normal master mode. As an example, increasing the center channel volume by three steps would result in a 3 being displayed until the volume control reverted to normal operation, at which
point the display would again indicate the overall volume setting.
8
REAR
Pressing this button followed by the volume +/– buttons will alter the relative volume of the Rear speakers relative to all others. The resulting offset
will be indicated in the main display, as well as by the on screen display.
9
MUTE
Pressing the mute button will reduce the main output level of the preamplifier by a user-modifiable amount, ranging from 2.5 to 55 decibels (5 to 110
in the main display). Pressing the mute button a second time without adjusting the volume will return it to its previous setting. If you adjust the volume with either the front panel buttons or the remote control while in the
mute mode, the preamplifier will adjust its volume from the muted volume
and disengage the mute function. The factory default setting of the mute
circuit is -20 dB (a change of 40 units in the Main Display). (See Using the
PAV for information on changing the factory default setting.)
10
SUB
Pressing this button followed by the volume adjustment buttons will alter
the volume of the Subwoofer(s) relative to all other speakers. The resulting
offset will be indicated in the main display, as well as by the on screen display.
11
REFERENCE LEVEL INDICATOR
This LED indicator is lit when the PAV is playing at Home THX reference
level (normally calibrated during initial setup—see Output Level Calibration, p. 36).
12
RECALL BUTTON
Pressing the recall button restores the PAV to its calibrated reference settings for the relative output of all speakers. This is especially helpful after
having experimented with various settings of balance, center, rear, or sub,
or when comparing a modified surround default to “flat” balance, since one
touch of a button will restore your preamplifier to its original state (as determined by the setup calibrations stored in memory; see System Setup &
Calibration and Using the PAV for more details).
13
DELAY BUTTON
Pressing this button allows you to adjust (using the volume adjustment buttons) the delay introduced to the signal being sent to the rear channels,
between 15 and 30 milliseconds (mS). (See Setting the Surround Delay,
page 37, for more details.)
14
INPUT LEVEL BUTTON & INDICATOR
Pressing this button adjusts the input level (or offset) on the main signal
path. Together with the input level indicator in the main display immediately above it, it may be used to compensate for variations in level among
sources. This adjustment is important primarily for movie sources (since
Dolby Pro Logic circuitry is level-sensitive by its nature). When the Input
Level is set correctly, the green indicator LED should be on most or all of
the time during loud passages, but should never turn red (which would indicate an overload condition).
If overload should occur, pressing the input level button followed by the
volume – button will reduce the input level. Do so until the indicator remains green during even the loudest passages.
15
Conversely, if you rarely see the green LED illuminate during loud passages,
you should increase the Input Level to compensate for the relatively low
level of the source. Press the input level button, followed by the volume +
button to increase the input level.
15
SURROUND MODE SELECTOR
Pressing this button cycles among the various surround modes of the PAV:
• THX cinema — for movies which were mixed for theatrical release; both THX cinema and pro logic indicators are lit, confirming that Pro Logic is in use whenever the THX cinema mode is
selected.
• pro logic — for all other surround-encoded material, such as
many TV shows and some music recordings; only the pro logic
indicator is lit.
• stereo surround — for enjoying two-channel stereo recordings
using all loudspeakers; the stereo surround indicator is lit.
• mono surround — for monophonic recordings which would benefit from some degree of additional ambience or spaciousness,
such as many classic movies and some sporting events; the mono
surround indicator is lit.
• surround off — to return the system to two-channel stereo; the
surround off indicator is lit.
• mono —a “true” mono, reproduced only through the center channel speaker and subwoofer. Noisy mono soundtracks often enjoy
significant noise reduction by being reproduced in this mode;
both mono and off indicators are lit to denote the fact that the
surround circuitry is disengaged, leaving you with a “true” mono.
16
PATH SELECTOR
Pressing this button cycles among your various signal path options:
• main — the home theater; this path determines which video and
audio sources are sent to the Main outputs on the back of the
PAV. Sources selected for the main path are indicated in yellow on
the front panel LEDs. (If the LED blinks red, it is indicating a
tape loop condition caused by the same source having been selected on the record path; deselect the source on the record path
first, then reselect your main source.)
• remote — determines which video and audio sources are sent to
the Remote outputs on the back of the PAV, to be sent to another
system elsewhere in the house. These sources are indicated in
green on the front panel LEDs. The remote path may also be
used as a secondary Record Output path if necessary.
• both — the audio and video signals for both main and remote
paths may be selected at the same time, for your convenience; as
when entertaining, perhaps, for whole-house background music.
Sources selected for “both” main and remote paths will be indicated by yellow LEDs (the same as for the main signal path).
• record — determines which video and audio sources are sent to
the various record output jacks. The source selected for the
record path is indicated on the front panel in red LEDs. As a
safety measure, the PAV will prevent the selection of any recordable device as its own source (to avoid feedback loops). If such a
selection is attempted, the PAV will cause the appropriate LED to
16
flash yellow on the front panel, indicating a conflict on the main
path. The PAV will also display the words tape loop on screen as
a warning.
Tip:
To avoid any possibility of running into a “Tape Loop” problem
(where the PAV prevents you from choosing what you want, in
order to protect the system from possible damage), simply
select a non-recording source such as TV on the record path.
17
STANDBY BUTTON
Pressing this button places the PAV in standby mode, turning off the display,
disengaging all control functions, and turning off all outputs. The internal
circuitry remains on in order to maximize performance on demand by virtue of all circuits remaining thermally stable. Lest you think this wasteful,
you should know that the PAV draws less than power than a typical light
bulb, whether in standby or fully on. The benefits of having it always
warmed up and ready to go (and always able to respond to remote control
commands) far outweigh the small amount of power used. We recommend
using the rear panel power switch only when you will be away from the
house for extended period of time, such as during a vacation.
There is another good reason for using the PAV’s standby mode. The PAV
will generate a full-frame black video signal at its video outputs during
standby, rather than passing no signal at all. This is particularly helpful with
many projections televisions, since it gives the projector a “sync” signal to
lock onto without calling for any light to be generated. This feature allows
the projector to remain fully warmed up at all times without risking damage to the phosphors which create the projected light.

SINGLE-ENDED AUDIO INPUTS (8)
Accepts right-channel and left-channel audio signals from source equipment
with single-ended (RCA) outputs. Single-ended audio inputs are provided
for a total of eight components, designated: vcr1, vcr2, tape1, tape2, a
laserdisc player, your tv (or auxiliary component), a cd2, and a tuner. Note
that the video portion of the signal from any video source (VCR, laserdisc,
TV) would be connected on the right side of the rear panel in the Video
Input section. (See below.)
Connect the right-channel and left-channel single-ended outputs of your
various source components to the corresponding inputs on the PAV.
2
BALANCED AUDIO INPUTS (2)
Accepts right-channel and left-channel signals from source equipment with
balanced outputs. Provisions are made for two balanced signals via high
quality XLR connectors, designated cd1 and bal/aux.
The pin assignments of these XLR-type female input connectors are:
PUSH
2 1

18
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
These pin assignments are consistent with the standards adopted by the
Audio Engineering Society. Refer to the operating manuals of your balanced-output line-level sources to verify that the pin assignments of their
output connectors correspond to the PAV. If not, wire the cables so that the
appropriate output pin connects to the equivalent input pin.
Connect the right-channel and left-channel balanced outputs of your source
components to the corresponding balanced inputs on the PAV.
Note: If you do not have balanced sources and need more singleended inputs, it is possible to fabricate a cable to connect linelevel sources with single-ended output to these balanced inputs:

VIDEO INPUTS (4)
Four video inputs are provided in the PAV, designated: laserdisc, tv/aux,
vcr1, and vcr2. These inputs may be configured for use with either composite or S-video (Y/C) signals during setup. Composite video inputs use
RCA connectors. S-video inputs utilize “S” connectors:
S-video connector
The PAV does not provide for “cross-feeding” of S-video and composite signals. Any signal entering the PAV in either format will be output in the same
format only. We strongly recommend standardizing on one or the other
throughout the system for maximum ease of use. In addition, using both
the composite and the S-video inputs simultaneously may result in a loss of
video signal quality.
Connect the video outputs of your video components to the corresponding
video inputs on the PAV. (See System Setup and Calibration for more information on programming these inputs for either composite or S-video use.)
Installation Note:
S-video (Y/C) signals are more susceptible to degradation
over long wire runs. The quality of wire used makes a
significant difference, but regardless, it is generally
inadvisable to run S-video cables more than six or eight feet
(2–2.5 meters). Composite video signals hold up better over
longer runs, especially when high quality 75Ω cable such as
Madrigal MDC-2 is used.
19
4
AC POWER SWITCH AND AC POWER INPUT
An AC power switch is provided which disconnects the PAV from the wall
outlet’s AC power. The PAV is designed to be left in Standby when not in
use, rather than completely “off.” Being in Standby allows it to respond to
commands from the remote control and maintains a stable operating temperature at all times for optimal performance and longevity.
Plug the supplied three-prong power cord into the AC Power Input
recepticle provided before plugging the power cord into the wall. If a
longer AC power cord is required for your application, be sure to use a
three-conductor power cord which conforms to IEC standards.
The Proceed PAV has been safety-tested and is designed
for operation with a three-conductor power cord. Do not
defeat the “third pin” or earth ground of the AC power cord.
Beside the power switch you will find a communications port. This is reserved for future use (communicating with the PAV's companion piece, the
Digital Surround Decoder). Do not insert anything into this port other than
the communications cable from a “DSD.”
5
REMOTE IR AND REMOTE TURN-ON
A 1⁄8" “mini” jack labeled remote ir. in the lower right corner of the rear
panel provides direct access to the infrared control circuitry of the PAV. It
may be configured during setup (in an on screen menu) to interpret incoming signals in either of two ways:
• Remote: when in Remote mode, the PAV will interpret any command entering through the remote IR jack as being intended to
affect the remote path only. This feature allows easy access to all
sources connected to the PAV from elsewhere in the house with
the addition of any commercially-available IR repeater.
• Local: when in the Local mode the remote IR jack replaces the
infrared receiver in the main display of the front panel. This
mode is most often used with an IR repeater when the PAV and
other components are placed inside of cabinets (preventing the
normal IR receiver from receiving remote commands). Setting the
remote IR jack to local will disable the IR receiver in the main
display to avoid inconsistent operation which might be caused by
interference between the two. (See Programming the IR Input,
page 47.)
The incoming signal for the remote IR input should conform to widely-accepted IR repeater standards: that is, the signal present should be between
3-15 volts DC at less than 100 mA current, with a positive tip polarity, as
shown below:
IR input tip polarity
–
+
3-15 volts @ less
than 100 mA
20
Your Proceed dealer can help you take advantage of these design features
to maximize your system’s versatility.
The remote turn-on output to the right of the remote ir input (as seen from
the rear) can be used to toggle Proceed power amplifiers between standby
and operate in concert with the operational status of the PAV. This output
normally provides a 300 msec long, 8 volt positive pulse whenever the PAV
turns on, and a 600 msec long, 8 volt positive pulse whenever the PAV turns
off. (Alternatively, the PAV may be configured to provide a level control voltage that can be used by certain Niles controllers and similar products. See
System Setup and Calibration for more information.)
To enable the PAV to control the turn-on and turn-off of the associated Proceed amplifiers, connect a wire terminated with a 1⁄8" “mini” plug at both
ends (available in various lengths at electronics supply stores such as Radio
Shack, or may be custom made to length by your installing dealer) between the remote turn-on output of the PAV and the remote turn-on input
of the AMP. If more than one Proceed amplifier is being used, simple “Yadapters” may be used to daisy-chain the turn-on signal for up to three
AMPs’ turn-on inputs.
6
VIDEO OUTPUTS
Four video outputs are provided in the PAV: main, remote, vcr1, and vcr2.
S-video (Y/C) outputs utilize four-conductor “S” connectors, while the composite video outputs use RCA connectors.
The main output should be connected to your video monitor in the main
home theater system. The remote output can be used to feed video signals
to another system elsewhere in the house. The remaining vcr1 and vcr2
outputs are used for making recordings on those decks via the PAV, much
as you would make audio cassette recordings with a traditional preamplifier
or receiver. Connect them to the corresponding inputs on the back of those
video tape recorders.
Installation Note:
S-video (Y/C) signals are more susceptible to degradation
over long wire runs. The quality of wire used makes a
significant difference, but regardless, it is generally
inadvisable to run S-video cables more than six or eight feet
(2–2.5 meters). Composite video signals hold up better over
longer runs, especially when high quality 75Ω cable such as
Madrigal MDC-2 is used.
The PAV does not provide for “cross-feeding” of S-video and composite signals. Any signal entering the PAV in either format will be output in the same
format only. For most people, it is simplest to standardize on one format or
the other throughout the system. While it is possible to use a combination
of both types of signal, this setup would require manual switching of inputs on the video monitor whenever the monitored video source changed.
In addition, using both the composite and the S-video outputs simultaneously may result in a loss of video signal quality.
21
7
REMOTE BALANCED OUTPUTS
If the system being used in the remote zone is equipped with balanced
(sometimes called “differential”) inputs, it is best to use these balanced outputs on your PAV. A balanced signal from preamplifier to power amplifier
will offer the highest possible performance with the best immunity from
common-mode noise, such as electromagnetic interference (EMI) or radio
frequency interference (RFI). This characteristic immunity is particularly important when using long cable runs, as may be expected when sending a
signal to a remote location. The balanced output signal is made available by
way of precision male XLR connectors (requiring female XLRs on the PAV
end of the interconnecting cable).
The pin assignments of these XLR-type male outputs are:
1 2
3
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
Refer to your amplifier’s operating manual to verify that the pin assignments
of its input connectors correspond to the PAV. If not, wire the cable so that
the appropriate output pin connects to the equivalent input pin.
Connect the right-channel and left-channel balanced remote outputs of
the PAV to the appropriate balanced inputs of the remote system.
8
MAIN BALANCED OUTPUT
If the power amplifier being used to drive the Front Left and Front Right
speakers is equipped with balanced (sometimes called “differential”) inputs,
it is best to use the balanced main outputs on your PAV. A balanced signal
from preamplifier to power amplifier will offer the highest possible performance with the best immunity from common-mode noise, such as radio
frequency interference (RFI). The balanced output signal is made available
by way of precision male XLR connectors (requiring female XLRs on the
preamplifier end of the interconnecting cable).
The pin assignments of these XLR-type male outputs are:
1 2
3
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
Refer to your power amplifier’s operating manual to verify that the pin assignments of its input connectors correspond to the PAV. If not, wire the
cable so that the appropriate output pin connects to the equivalent input
pin.
Connect the right-channel and left-channel balanced main outputs of the
PAV to the appropriate balanced inputs of the remote system.
9
22
SINGLE-ENDED MAIN OUTPUTS
Single-ended (“unbalanced”) outputs are provided for compatibility with a
wide range of associated components.
If you use the single-ended main outputs, connect them to the corresponding inputs of the amplifier being used to drive the Front Left and Front
Right speakers.
10
SINGLE-ENDED REMOTE OUTPUTS
Single-ended (“unbalanced”) outputs are provided for compatibility with a
wide range of associated components, including power amplifiers and electronic crossovers.
If you use the single-ended remote outputs, connect them to the corresponding inputs of your remote amplifier (or other device).
11
REAR SURROUND OUTPUTS (SINGLE-ENDED)
Connect these outputs to the input of the power amplifier being used to
drive the surround speakers, which are normally located at the sides or the
rear of the room.
12
CENTER & SUBWOOFER OUTPUTS (SINGLE-ENDED)
The upper of these two RCA jacks should be connected to the amplifier
channel which will drive your center channel speaker; the lower RCA jack
should be connected to the amplifier channel which will drive your
subwoofer(s).
If you have two channels of amplification driving multiple subwoofers, simply wire them in parallel from this output, using a Y-adapter. The output
circuitry of the PAV can easily handle the extra amplifier without any loss of
performance.
Please Note:
If your system does not have a subwoofer, leave the sub
output empty. Also be sure the crossover is turned off during
Setup in order to give your front loudspeakers a full-range
signal. (See System Setup & Calibration for more details.)
13
RECORD OUTPUTS (SINGLE-ENDED)
Four audio record outputs are provided, which are designed to work in
concert with their corresponding inputs. For example, you would connect
the vcr1 outputs to the audio input jacks on the video tape recorder you
had connected to the vcr1 input. The record outputs are: vcr1, vcr2, tape1,
tape2.

Learning Remote Control
1
INDICATOR LEDS
These indicators provide visual feedback on the operation of your PAV
learning remote control.
• ready to learn: when in the Learning mode, this LED lights to
indicate that the PAV learning remote is ready to learn new commands, either from the PAV itself or from another remote control.
It is illuminated only in the Learning mode, and it turns off
briefly each time a command is successfully learned.
• learned/sending: when in the Learning mode, this LED lights to
indicate that the PAV learning remote is ready to learn new commands, but needs you to select the button which you would like
to program. This LED will blink briefly after a command has
been learned to confirm success.
During normal operation, this LED indicates when the remote
control is sending an infrared command.
• error/low battery: when in the Learning mode, this LED lights to
indicate that the remote did not “understand” the command you
gave it (error—try again). During normal operation, this LED indicates when the batteries need to be replaced, or that a button has
been pressed that has not had a command assigned to it.
For more information on the Learning mode, see Programming the Remote
Control.
24

BANK SWITCH
The PAV learning remote has two complete “banks” of settings which may
be stored for your use. As delivered from the factory, many but not all of
the buttons in the “Proceed” bank (the one in use when the sliding switch
is under the Proceed logo) have been preset to control the PAV. The remaining buttons in the Proceed bank are available to operate your primary
source component(s). In this way, you should rarely have to switch to the
second bank of controls.
Still, some home theater systems involve many remote-controlled components and may require more remote functions than a single bank of buttons can easily provide. Sliding the switch to the “2” position gives you a
“clean slate” of buttons in which to store more remote control functions. All
of the settings in Bank 2 are left unprogrammed, ready for you to set up for
whatever uses you see fit.
For more information on the teaching your remote control new functions,
see Programming the Remote Control.

Caution:
USE/LEARN BUTTON
This button is recessed to prevent accidental use, and must be accessed
with the tip of a pencil or similar pointed object.
This button allows you to alter the remote control commands
stored in the PAV remote’s memory. Please read the section of
this manual entitled “Programming the Remote Control”
completely before engaging the use/learn button.
When engaged, the use/learn button will toggle the remote control between normal, day-to-day operation and the Learning mode. When in the
Learning mode, the ready to learn indicator LED will be lit. If you have inadvertently entered the Learning mode, press the use/learn button again to
return to normal operation and the ready to learn indicator LED will be
extinguished.
For more information on the teaching your remote new functions, see Programming the Remote Control.
4
a, b, c, d BUTTONS
These “extra” buttons are provided for your convenience and may be programmed with any function you wish (above and beyond the other, more
specifically-labeled buttons on the remote control). For example, if your
cable-TV converter box uses both A and B trunks, you might program a
and b accordingly to select the incoming cables. Alternatively, you may wish
to program all four buttons to directly access the different signal paths
(main, remote, both, record) without having to cycle through the choices.
The PAV can teach such “Direct Access” commands directly to your remote
control. For more information, see Programming the Remote Control.
25
5
e, f, g, h, std by BUTTONS
The first four of these buttons are simply more “extras” provided for your
convenience, as with a through d above. You may want to program them
for direct access to your favorite surround modes (THX cinema, pro logic,
stereo surround, surround off), for example. The PAV can teach such “Direct
Access” commands directly to your remote control. For more information,
see Programming the Remote Control.
The std by button will place the PAV into standby mode. As with all buttons on the learning remote, this button can be “programmed over” if you
wish. For example, you may decide to leave the PAV “on” all the time and
use the std by button to turn your television on and off instead.
6
TRANSPORT BUTTONS
This section of the PAV learning remote control groups the most-used features of a source component together, be it a CD player, a VCR, or a laserdisc player. This design allows you to put one or more of the remote controls in your coffee-table collection away in a drawer, leaving only the single
PAV remote to provide all of the day-to-day commands you require.
For more information on the teaching your remote new functions, see Programming the Remote Control.
7
INPUT SELECTION AND NUMERIC KEYPAD
This section of the PAV learning remote control does double duty:
• When in the Proceed bank, it normally provides direct access to
the inputs printed above the various buttons. In addition, it provides for channel increment and channel decrement (ch+ and
ch–) for your television tuner (a function that will need to be
programmed into the remote) without having to change banks.
• By sliding the Remote Bank Switch to position 2, however, you
may “teach” the learning remote to operate as a conventional numeric keypad such as you might have on the remote controls of
your cable decoder or television.
This feature allows you to put yet another remote control from your coffeetable collection away in that drawer.
8
PAV OPERATIONAL CONTROLS
This section of the learning remote contains the most often used controls
for the Proceed PAV.
• menu: when the on screen menu is not displayed, pressing this
button will bring up the main menu. Once in the menu screen,
pressing menu will exit your current level without making any permanent changes, returning you to the next-higher level. Repeated
pushes of menu will ultimately take you out of the menu system.
• mode: pressing this button cycles the PAV through the various surround modes, indicated both on the front panel and on screen.
• on screen: pressing this button will turn the on screen display off
to avoid the distraction of status updates whenever you adjust the
volume, change surround modes, etc. Pressing the on screen button again will restore the normal on screen function.
26
• path: pressing this button will cycle the PAV through the various
signal paths. Having selected a particular path, subsequent source
selections affect only that path (e.g., main, remote, both, or
record).
• recall: pressing this button restores the various channel offsets to
their calibrated, most accurate settings (set up during installation
and calibration). You can experiment with adjusting the levels of
the subwoofers, center channel, surrounds, etc. to suit your preference or a particular recording, knowing that a single press of recall will restore the PAV to its calibrated settings.
• bal: pressing this button temporarily allows the volume +/– keys
to affect the balance of the left front and right front speakers
rather than the overall volume.
• delay: pressing this button temporarily allows the volume +/–
keys to adjust the amount of time the rear channel signals are
delayed when in the various surround modes. This time delay
may be adjusted between 15–30 mS in 1 mS increments.
• sub: pressing this button temporarily allows the volume +/– keys
to affect the level of the subwoofer relative to the rest of the system.
• rear: pressing this button temporarily allows the volume +/– keys
to affect the level of the rear (surround) speakers relative to the
rest of the system.
• cntr: pressing this button temporarily allows the volume +/– keys
to affect the level of the center front speaker relative to the rest of
the system.
• master: pressing this button allows the volume +/– keys to affect
the overall volume of the system, maintaining any relative settings
between the various loudspeakers. This is the default mode for
the volume +/– keys, to which the PAV will return after a few seconds of inactivity.
• display: pressing this button will turn off the front panel display
of the PAV to facilitate listening to music or watching movies in a
darkened room without visual distractions. The PAV’s display will
turn back on momentarily when adjusting the unit’s operation in
order to acknowledge the changes. The display may be returned
to its normal, always-on mode by pressing the display button
again.
• input: pressing this button temporarily places the volume +/–
keys in input level mode, allowing you to fine-tune the input sensitivity of each particular input for proper Pro Logic calibration.
This control also allows you to adjust the relative volumes of the
various source components to avoid abrupt changes in volume
when switching between inputs.
• mute: pressing this button duplicates the function of the mute
button on the front panel, reducing the volume of the main system by a user-selectable amount.
• volume +/–: these buttons normally adjust the overall system volume, although they are also used in conjunction with other buttons and/or menu items to vary most of the available system adjustments.
For more information on the teaching your remote new functions, see Programming the Remote Control.
27
Planning Your Installation
The information contained within this section is intended to help get someone
started who wishes to design and install their own sophisticated A/V system built
around the Proceed PAV. However, it cannot be considered a substitute for the experience, expertise and specialized training of an audio/video installation professional. (See A Word About Installation, page 9.)
Choosing The Equipment
The list of equipment needed for a full home theater system based on the PAV is
fairly straightforward:
• The Proceed PAV
• At least six channels of amplification (Left, Center, Right, two Surrounds, and one or more Subwoofers)
• Additional amplification (with volume control) and loudspeakers if
a remote zone is to be used. (Alternatively, this output may be
used in conjunction with a third-party multi-room system.)
• Left, Center and Right (LCR) front speakers with appropriate stands
or mounting brackets
• One or more subwoofers (required with THX speaker systems;
otherwise optional, but recommended)
• A pair of Surround speakers with appropriate stands or mounting
brackets
• Assorted appropriate interconnecting cables, speaker wires, etc.
Of course, you will also need at least one source and a display system. The best
consumer video sources, in order of quality, are:
•

Planning Your
Equipment Placement
Laserdisc
Direct Broadcast Satellite link (DBS, DSS)
a good cable-TV or antenna signal
Super-VHS tape
Hi-8 mm videotape
regular VHS videotape
The “light pollution” created by some components can be significant and distracting. Ideally, all equipment should be conveniently located for operation, but any
lights and other indicators should be out of your direct field of vision when
viewing the television picture. The various indicator lights, though essential for
proper operation, can be distracting when listening to music or watching a movie.
While the PAV’s display may be turned off (with the display button on the remote control) to eliminate this problem, other components are unlikely to have
this feature.
Care should also be taken that any mechanical noise created by VCRs, laserdisc
players, etc. does not intrude on the viewing experience. Placing the equipment
behind opaque doors, inside a cabinet addresses both light and noise concerns.
Should this option be chosen, a hard-wired remote IR input is provided on the
PAV’s rear panel to replace the IR input which would normally be received
through the receiver in main display. Alternatively, locating the components well
away from the field of vision can be effective (if mechanical noise from transports, etc. is not a problem).
28
Attention should be paid to the accessibility of the infrared control signal to the
components. Most people instinctively aim remote controls at the screen, without
thinking about the location of the equipment. It is a good idea to locate a small
infrared “repeater” in the vicinity of the screen, set up to relay the signal into the
equipment area and/or the PAV’s remote IR input. This is especially true if the
equipment has been isolated from plain view, inside cabinetry.
The “Correct” Size for
Your Television Screen
The Power Amplifiers
Video images will often be displayed on some sort of projection system, since
the increased size will give you a more film-like experience. There may be situations where a 31"–35" direct-view television is appropriate (in smaller rooms, for
example). But do not give in to this temptation too easily—part of the theater
experience is the visual impact of having your field of vision dominated by the
size of the image on the screen. A good rule of thumb is to use a
diagonal screen size of approximately 1⁄2 to 1⁄4 the planned viewing distance. Thus,
if your seating is 12 feet from the screen, you would like to use a television with
a 3 to 6 foot (36"-72") diagonal screen measurement. In this case, a 35" directview television might be just adequate. A larger screen would be preferable, especially if you plan to watch many letterboxed movies. If your video system includes a line doubler for enhanced resolution, take advantage of the improved
picture clarity by using a larger screen (closer to the one-half-the-distance figure).
Given the dynamic range of modern soundtracks and people’s expectations of
their home theater systems, at least 100 w/ch is recommended for all six channels, with few exceptions. Still more power may be required in unusually large
rooms.
A common misconception is that the center and surround speakers have lower
power requirements than do the rest. This is proven untrue by the mathematics
of Dolby Pro Logic processing. The center channel is the hardest-working speaker
in a movie soundtrack’s mix. You should also be forewarned that the surrounds
are working harder than your first impression might indicate. While they may require less power on average, there are moments during which they are the loudest speakers in the room (as when an aircraft seems to fly overhead, for example). Prudent system design requires that the surround channels have enough
power to reproduce their signals without amplifier clipping, even under such a
worst-case scenario.
The Left, Center and Right
(LCR) Front Speakers
The goal of the front speakers is to accurately recreate the sounds that would be
coming directly at you in real life situations. It is important that they be accurate
in terms of tonal balance, dynamic capabilities, and imaging precision if they are
to recreate a convincing soundstage (whether of music or film soundtracks). They
also need to be well-matched to one another—do not skimp on the center channel speaker, as it is the most important loudspeaker in the entire system when it
comes to movie reproduction.
Ideally, all three Front speakers would be at the height of the screen. Of course,
the center channel speaker would then obscure the screen, so placement above
or below the screen is usually required. All three speakers should be close to the
same height, however, to avoid distracting changes in apparent altitude as sound
is panned across the screen.

Some toe-in of the Left and Right speakers toward the main listening area (see
above) will help minimize side wall reflections and balance the sound for people
at the extreme edges of the viewing area. Placing the center speaker at the same
distance as the left and right is also important (note the arc in the diagram
above).
If possible, it is usually desirable to have the side walls between the front speakers and the listener be acoustically absorptive to further minimize early side wall
reflections. Plush drapes, wall hangings, and various commercially-available materials can do the trick nicely. (Consult with your dealer for further ideas.)
The Subwoofer(s)
The Proceed PAV is designed to use a common-bass subwoofer, meaning that the
low frequency information from the controller is summed to a single channel.
This can be done without degrading the stereo effect because the human ear
cannot readily localize sounds below about 120 Hz. In addition, virtually all program material (music and movies) is monophonic below 100 Hz. As a result,
there is a great deal of flexibility in the placement of the subwoofer(s). The primary goal is to have bass which can deliver visceral impact without becoming
boomy or distorted. In order to achieve this, attention must be paid to room
placement to minimize the “room modes” (or standing waves).
A good rule of thumb is to place your subwoofer(s) asymmetrically in the room,
at “odd fractions” (1⁄3, 1⁄5, 2⁄5, etc.) of the room’s length or width.

You may also want to try to keep your subwoofer(s) within three feet (one
meter) of the circle formed by anchoring a string at the main listening position
and swinging the other end through the front speakers. (Doing so minimizes and
30
phase-induced irregularities at the crossover frequency of 80 Hz.) Of these two
guidelines, the first is usually more significant sonically, as it tends to minimize
the audibility of the room’s modes. Avoid corner placement, as this typically increases bass quantity at the expense of bass quality (by stimulating every room
mode supported by the room).
The actual number of subwoofers used in an installation will depend on both
the size of the room and on the manufacturer’s design. Of course, having multiple
subwoofers enhances the maximum level at which they will play. Additionally,
there is an advantage to having more than one subwoofer in the room. Smoother
bass may be obtained by placing two subwoofers asymmetrically in the room,
since different sets of room modes would then be excited by each. The peaks of
one set of room modes could offset the valleys of the other one to some degree.
The Surround Speakers
Ideally, the rear speakers will create a diffuse, non-localizable soundfield which
envelopes the listener. Creating this effect depends in part on the loudspeakers
chosen for the job.
If THX-certified dipolar surround speakers are used, they should be located high
and to the sides of the listening area, firing to the front and the rear of the room.
(See diagram, below.) This placement ensures that the audience will not be able
to localize them as sources of sound, but rather will be enveloped in a diffuse
soundfield. They should be at least two feet above ear level when seated. Ideally,
they would be placed somewhat above ear level even when standing, so that they
are unlikely to be localized as people walk around the room.

If more traditional speakers are used, they should be placed such that their output is scattered across the rear of the room. (See diagram, next page.) Often, the
best results will be obtained by placing them relatively high and slightly behind
the listener, cross-firing across the rear wall so as to create a large number of reflections with relatively little direct sound arriving at the listening position.

Low impedance speaker wire must be used throughout the system. This ensures
the most efficient transmission of power from the amplifiers to the speakers,
which minimizes several forms of audible distortion. Surprisingly, not all speaker
wires (including some of the audiophile variety) meet the necessary criteria. As
always, your best source of advice is your trained dealer/installer. However, the
table below may be used as a worst-case general guide. When in doubt, use a
thicker (heavier gauge) wire than is specified below.

Large rooms (in the 4000-6000 cubic feet range) have so much air to move that
they may benefit from having additional subwoofers for greater bass impact. The
PAV’s subwoofer output can easily drive several power amplifiers—simply split its
output with Y-connectors.
Another technique for large rooms involves the construction of risers for the seating area in a dedicated home theater. Risers tend to enhance the visceral effect of
deep bass by providing a resonant platform for the couches and chairs, thereby
transmitting structural as well as airborne vibrations to the audience. This approach can be used alone or in conjunction with extra subwoofers. If both techniques are used, consider building one or more subwoofers into the riser, which
both conceals the subwoofer’s bulk and maximizes the vibrations being transmitted to the listener’s chair. (Action movies will never be the same.…)

System Planning Guide
Experience shows that almost any reasonable amount of time spent in the planning stages will pay for itself two to three times over during the installation—
more if the installation crew includes two or three people. With the background
provided in the previous sections, the planning process can be boiled down to a
checklist which will ensure that you do not overlook anything important.
Video Placement
■ The primary seating area should be perpendicular to the picture.
■ Be aware of the trade-off between screen size and perceived clarity. The resolution of NTSC requires a seating distance of at least 4
times the diagonal screen size for maximum perceived clarity (this
is why small screens seem so sharp). Yet larger images have greater
visual impact. You may want to go for a seating distance of as little
as 2 times the screen size to increase visual involvement (although
this is probably only realistic if you have a line-doubled television).
■ Stray ambient light should be minimized. (Drapes, dimmers, light
placement)
■ Leave room for the Left, Center, and Right (LCR) speakers up front,
flanking the screen itself, placed with reasonable symmetry with
respect to adjacent walls, and all at the same distance from the primary viewing area.
■ The screen should be well away from side walls, since you want to
minimize side wall reflections from the front (LCR) speakers.
Electronics Placement
■ Cabinetry is generally preferred to conceal the distracting LEDs on
the equipment. (An infrared repeater system may be needed in
this case.)
■ The ideal system would have invisible, yet readily accessible equipment and an IR repeater to relay the user’s commands from the
area of the screen to the concealed electronics.
■ People tend to aim their remote controls at the screen, regardless
of where the equipment is. In the absence of IR repeaters, placing
the electronics near the screen makes the system’s operation more
intuitive.
■ Ample ventilation for the power amplifiers must be provided, preferably through convection (to avoid fan noise).
Speaker Placement
■ Can the speakers be used as designed? (Wall-mounting speakers
designed to be used in free space may create a mid-bass bump in
the response—consult with the manufacturer of your speakers as
to their best use.)
■ The Left and Right speakers often should be closer to the edges of
the screen than you may think best initially. There is some cognitive dissonance (disorientation) when sound appears to come from
well away from its apparent visible source.
■ The Center speaker should be centered on the screen, directly
above or below it (unless you have an acoustically transparent
screen, in which case it may be directly behind the center of the
screen). Try to keep its tweeters as close to the level of the tweeters in the L&R speakers as possible, so that pans do not involve
noticeable changes in altitude. Make sure that the Center speaker is

Speaker Placement

the same distance from the main listening area as the Left and
Right speakers.
If THX-certified LCR speakers are used and must be either above
or below ear level when seated, aim them down (or up) into the
listening area. They are intentionally quite directional in the vertical
plane, to improve dialog intelligibility and localization.
Placing the LCRs below the screen is generally preferable to placement above.
The subwoofers do not have to be extremely close to the LCRs—
anywhere in the room is all right, but placement will affect the
consistency of the low bass. Experimentation is in order.
Dipolar surrounds should be located high and to the sides of the
listeners instead of behind them, in order to place the audience in
the surround speakers’ null. If the viewing area is more than one
row deep, place the surrounds halfway back within the seating
area.
If architectural constraints prevent ideal placement of dipolar surrounds directly to the sides of the listening area, it is generally best
to err on the side of being a bit further to the rear of the room.
When using traditional speakers for the surround channels, the
speakers should be located high and somewhat behind the listeners, with the speakers’ output directed toward the rear wall rather
than at the listeners.
The surrounds should be relatively high, often near the ceiling for
the best results. And they should be located equally distant from
their adjacent walls/ceilings, or else one will have more mid-bass
than the other.
• Some allowance must be made for those installations involving
relatively small screens, such as 35" direct-view televisions. Placing
the speakers immediately beside televisions of this size may reduce
the stereo separation to unacceptable levels. Some experimentation
is in order, but as a rule of thumb, try to have the L and R speakers
spread apart by no more than approximately 1.5 times the width of
the screen to avoid cognitive dissonance from the apparent conflict
between visual and aural images.
• With regard to subwoofer placement, it is important to leave yourself some leeway during final installation for minor movements to
minimize room modes. Corner placement will yield the most deep
bass, but it will usually be lumpy and irregular, as this placement
excites the maximum number of standing waves.
• Use multiple subwoofers if more bass output is needed. This also
has the advantage of allowing one subwoofer to fill the other’s
“holes” created by room modes, while reducing distortion by giving
each subwoofer an easier task.
System Setup & Calibration
The PAV uses on screen menus to make the initial setup of this sophisticated
control center as simple as possible. In addition, there are a few on screen menus
which can be used occasionally, if you change your preferences as to how the
system should operate.
Operating the On Screen
Menus with the Remote
There are five keys on the remote control which are used to “navigate” through
the on screen menu system.
• menu: when no on screen menu is displayed, pressing this button will
bring up the main menu. Once within the menu hierarchy, pressing
menu will exit the level you are currently on without making any permanent changes, returning you to the next-higher level (much like “Cancel” on a computer). When at the top level, or main menu, the menu
button will take you out of the on screen menu system.
• master: conveniently placed adjacent to the volume +/– buttons, the
master button serves the “select” function when in the on screen menus.
Pressing the master button will move the cursor indicating the currentlyselected menu item on to the next item in the list. At the end of a list,
master will move you back to the first item on the list.
• volume + and volume –: once a menu item has been selected by the
master button, pressing either of these buttons will act upon that menu
item. These actions will either increment a setting up or down directly,
or take you to the next level of the menu structure so that further action
can be taken.
• enter: any changes made to the settings within the on screen menu system must be explicitly entered in order to be saved for future use. This
extra step minimizes the chance of unintended changes being made by
those who are casually exploring the menu system. If a change is made
and not entered, the PAV will display last chance to saved changed
items on screen. Press enter to save your change, or menu to exit without saving any changes.
Operating the On Screen
Menus from the Front Panel
All of the above functions can also be accessed from the front panel of the PAV
(especially helpful if the remote control is not available).
• recall: the menu function is provided by the recall button. In order to
activate the on screen menus rather than simply recalling the reference
level settings, press and hold the recall button until the front panel lights
are turned off (about five seconds). From this point on until you exit the
menu system, the recall button will perform exactly as the menu button
on the remote control would.
• master: the front panel master button is also conveniently placed adjacent to the volume +/– buttons, and serves the same purpose as the one
on the remote control.
• volume +/–: the front panel volume +/– buttons also operate in the
same fashion as their counterparts on the remote control.
• standby: the enter function is provided by the standby button on the
front panel (when the PAV is in menu mode). It is deliberately set apart
from all of the other menu-related buttons to make permanent changes
of system parameters a deliberate act.
35
Setting Up
All surround processors require a certain amount of setup before they can perform correctly. This fact is also true for audio/video preamplifiers such as the PAV
which incorporate surround processing as part of their design. Briefly, and at a
minimum, you must “inform” the PAV about the nature of the loudspeakers with
which it is working, and you must calibrate the various outputs so that all the
loudspeakers can operate on a “level playing field” despite variations in sensitivity
and room placement. For an overview of the process, see the flowchart below.
Set Speakers
Once the physical installation of the PAV is complete, the next step is to configure
the PAV for the specifics of the particular system.

SELECT “SET SPEAKERS,” AND TURN THE CROSSOVER ON OR OFF, AS
NEEDED.
Turning this control on introduces an 80 Hz, 12 dB/octave high pass filter
to the three front channels (attenuating their lowest frequencies). If you are
using the PAV’s electronic crossover to drive a subwoofer in your system,
the subwoofer will handle everything from 80 Hz down.

frequency of 80 Hz on its output. Its signal is derived from all three front

SELECT LARGE, SMALL, OR NONE FOR YOUR CENTER SPEAKER.
The PAV has the ability to remove bass information from the Center channel
and “split” it out to the Left and Right speakers (which are presumed to
have better bass reproduction capabilities). Informing the PAV that you have
a large center speaker (e.g., one which can reproduce bass) will pass a full
range signal on to the center channel. Using the volume +/– keys to toggle
to small will split frequencies below 120 Hz out to the Left and Right channels.
Note that this function operates independently of whether or not you have
a subwoofer. For example, THX-certified LCR speakers operate to 80 Hz,
below which it is assumed you would have a THX-certified subwoofer. Because of this, the LCRs are considered “large” speakers—they can reproduce everything that would ever be required of them.
36
If your system does not include a center channel speaker, choose “none.”
Doing so will place the PAV into a “phantom” center channel mode wherein
the information which would normally be directed to the center speaker by
the Pro Logic circuitry will instead be sent equally to both left and right
speakers. This process creates an illusion of a center channel speaker for
those sitting on the centerline between Left and Right speakers. (Having a
real center channel makes seating arrangements far more flexible than is
the case with only a “phantom” center.)

Neither of these settings has any effect on either the remote or the record

Physical Setup
Testing For Proper Phasing
Proper setup and calibration of your new system is essential to its performance.
There are several items which should be checked before making the various system adjustments.
You must be certain of having the proper phasing throughout the system before
level calibration can be established accurately and reliably. Accurate phasing of the
loudspeakers in the system is also essential for precise localization of images and
deep bass response. Ensuring proper phasing is made more complicated than it
might seem at first glance if amplifiers of different types are used in the system,
since some amplifier designs invert the phase of their output relative to their input. Speakers attached to these amplifiers must be connected so that their phase
is inverted again to get it back where it belongs.
The simplest way to ensure proper phasing in your home theater is to use only
non-inverting amplifiers (such as Proceed® and Mark Levinson® power amplifiers)
throughout the system and be extremely careful while making all amplifier/
speaker connections. If this approach is not practical, or if you have lingering
doubts about the relative phase of your loudspeakers, compare each speaker to a
single speaker which will be used as the reference. We will use the Left front
speaker as the reference in our example.
• Relative Subwoofer Phasing: if multiple subwoofers are used, it is
important to have their phase with regard to each other correct.
Reverse the polarity of one of the two subwoofers while program
material with deep bass is playing (being careful not to momentarily short the two speaker leads to one another). The slow low
frequency sweep “rattle test” on Lucasfilm’s WOW! laserdisc (Chapter 16) can be used for this purpose, or any of the below-80 Hz
warble tones on the Stereophile Test CD. You will immediately notice either a loss or an increase in bass. The correct polarity is the
one which exhibits the most bass.
• L–R Phasing: check Left-Right phasing by listening to mono pink
noise (such as the pink noise on Chapter 6 of WOW! or Track 4 on
the Stereophile Test CD) in the surround off mode. Listen for a solid,
stable center image. If in doubt, reverse the leads on the Right
speaker only and compare the results. Out-of-phase speakers will
37
have a poorly-defined image smeared all over their end of the
room.
• L–C Phasing: check Left-Center phasing in the Home THX mode
by repeating the L-R Phasing test after having moved the interconnect from the Right speaker’s amplifier input to the Center
speaker’s amplifier input. Don’t forget to move the interconnecting
cables back where they belong when you are done.
• Absolute Subwoofer Phasing: it is also important for both subwoofers to have the correct phase with regard to the rest of the
system. Now that the LCR speakers are all matched, play the 80 Hz
warble tone from the Stereophile Test CD. Alternatively, listen for the
“body hits” (when Indy gets slugged) in WOW! (These body hits
have a lot of energy at approximately 80 Hz.) Reverse the polarity
of all subwoofers (if using more than one) and listen again. The
polarity with the greatest bass output in this vital region is correct.
• Surround Phasing: using the pro logic mode (not the THX cinema
mode), stand halfway between and at some distance from the surround speakers with them facing you. With strong surround program material (such as Chapter 11 on WOW!, or the out-of-phase
pink noise test on the Stereophile Test CD), you should hear a solid
center image hanging between the surround speakers. (“Absolute”
phasing of the surrounds with regard to the front speakers is relatively unimportant, since the delay used to take advantage of the
precedence effect destroys any front-to-back phase integrity.)
A few minutes of extra attention paid to phasing at this stage of the installation
pays off handsomely in improved localization and in optimal bass performance.
This is particularly true if the amplifiers used are not identical.
Input Level Calibration
It is necessary to adjust the input level of sources in order to get the best results
from the system when used in either THX cinema or pro logic modes. This is because Dolby Pro Logic employs a modified version of Dolby B noise reduction,
which needs to be calibrated in order to ensure accurate tracking and decoding
of the soundtrack. This adjustment yields the best dynamic range from the surround decoder circuitry, and ensures accurate tracking of the steering circuitry in
Dolby Pro Logic. While not hyper-critical in the PAV, thanks to its extraordinary
signal-to-noise and headroom performance, adjusting it accurately will squeeze
the last bit of performance from your system.
A simple test tone can be used in conjunction with the front-panel level indicator
to calibrate the system. (Ch. 5 on Lucasfilm’s WOW! test laserdisc, or a copy
thereof for your VCR; Track 1 of the first Stereophile Test CD also has a suitable 20 dBFS, 1 kHz test tone.) Lower the master volume to “background” music levels
and then turn on the test tone. Adjust the input level until until the green LED
just above the input level button just turns on.
If no test tone is available, you can still calibrate the system with reasonable accuracy by turning up the input level control until the green LED is on most of the
time during loud passages in movies, but so as to prevent it from turning red at
any time (which would indicate the onset of clipping in the Dolby Pro Logic circuitry). Various movies are dubbed at slightly different levels, so you may want to
touch up this adjustment occasionally. Expect to see a 1-3 dB variation among
various film transfers.
Default input level settings may be set for each input in the PAV. Setting these defaults for each source in the system will have the effect of transparently eliminat-
38
ing differences in level between various sources (some of which may seem
“louder” than others without such a correction).
Output Level Calibration
LEFT FRONT
The PAV also incorporates level controls for each output. These allow you to
compensate for differences in amplifier and speaker sensitivities and for placement variations in different rooms. These adjustments are essential for reproducing proper soundstaging and image localization. Fortunately, they
are normally a one-time adjustment during setup, and only need to be revisited
if amplifiers or speakers change.
CENTER

SET LEVELS

The simplest and best way to adjust the output level controls is by using a dB
Sound Pressure Level (SPL) meter and the internal test tone generator. The goal is
to set the volume at the primary listening position to read 75 dB SPL (C-weighting, slow mode) from each speaker in sequence, using the individual output level
controls. You should point the meter at the ceiling so as to avoid inadvertently
favoring one speaker over another. (Note that if the tones in Chapters 8-11 of the
WOW! test disc are used, the meter should read 85 dB SPL, since these tones are
recorded at a level 10 dB higher than those generated by the internal generator. If
external tones such as these are used, you must also be certain that the input
level calibration has been done accurately prior to calibrating the output levels.)
In the absence of a dB SPL meter, it is possible to set the output level controls by
ear. Use the built-in pink noise generator in the PAV to adjust all volumes to
sound the same as they cycle around the various speakers. (This signal is bandwidth-limited pink noise to minimize the problem of timbre shifts influencing
the setting of levels.) The system will then be reasonably well balanced, although
of course it is not “calibrated.”

Pressing master will move the cursor (and the noise) on to the next

around the listening area, watching for the magnitude of the variations introduced by room modes at low frequencies. If more than 3-4 decibel
variations are seen within the listening area, consider re-locating your
subwoofers for more consistent results. (See Planning Your Installation for
specific suggestions on subwoofer placement.)

MAKE A NOTE OF THESE SETTINGS UNDER “YOUR SYSTEM SETTINGS” IN
THE BACK OF THIS MANUAL
Having these settings handy will prove helpful should anyone ever tamper
with your careful calibrations. Of course, you should re-calibrate the system
whenever changing amplifiers and/or speakers, or when something has a
noticeable effect on room acoustics (such as re-arranging the furnishings).

PRESS ENTER TWICE TO SAVE YOUR CHANGES
Since these settings are critical to achieving optimal performance from your
PAV, the on screen display will ask you whether you are sure you want to
make these changes, and tell you to press menu to escape without saving
those changes. Assuming that you do wish to save your changes, press enter
a second time to confirm and save the changes.
All Dolby Pro Logic decoders incorporate a delay to the rear speakers. This delay
takes advantage of the precedence effect, whereby we tend to localize on the first
sound we hear when being confronted with several similar sounds (as in the
case of surround sound, or a visit to a reverberant concert hall). The rear signal is
delayed somewhat to ensure that we never hear any potential leakage of the front
channels into the surround speakers, despite the fact that the latter are often
closer to the seating area than are the main speakers. This delay gives the sound
coming from the front speakers a chance to reach the viewer before the surrounds are heard. It can be varied from 15 to 30 milliseconds.
The best setting depends on the distance between the main seating area and the
front speakers, and the distance between the main seating area and the surround
speakers. (See below.)

1
MEASURE THE DISTANCE IN FEET FROM THE FRONT SPEAKERS TO THE
PRIMARY LISTENING POSITION
This number represents an approximate measure of the time it takes for the
front speaker sound to reach the listener, in milliseconds. (Since the speed
of sound at sea level is 1130 feet per second, sound travels approximately
one foot per millisecond—close enough for this sort of work, anyway. Similarly, people using the metric system may use the approximate conversion
of 3 feet = 1 meter.)
2
SUBTRACT THE DISTANCE (IN FEET) FROM THE LISTENER TO THE REAR
SPEAKERS
This difference represents the time “advantage” the rear speakers have over
the front speakers, measured in milliseconds. Since they are usually closer
to the listener than the front speakers, it is important for their signal to be
delayed.
3
ADD 15 TO THE NUMBER OBTAINED IN STEP #2 AND SELECT THIS SUM IN
THE SET DELAY MENU
For example, if your rear speakers are 7 feet closer to you than the front
speakers, add 7 to 15 to get 22 msec, which is the optimum delay for your
system. Use the volume +/– keys to set this value in the set delay menu.
4
MAKE A NOTE OF THESE SETTINGS UNDER “YOUR SYSTEM SETTINGS” IN
THE BACK OF THIS MANUAL
Having these settings handy will prove helpful should anyone ever tamper
with your careful calibrations.
Don’t be overly concerned about this setting—by its very nature, it does not have
to be exact. The goal is to delay the rear speakers enough to make them be perceived as secondary sources of sound, without introducing so much delay that
they sound like echoes of the original. In most systems, anything from 20–25
msec or so will perform just fine.
Setting Input Defaults
Although not really necessary for proper operation of the Proceed PAV, the input
defaults section of the setup menu allows you to customize certain aspects of
your PAV’s behavior.
The video portion of the input defaults menu also tells the PAV whether a particular video input is using the composite or the S-video connectors. This is important because it necessitates a change in the way on screen messages are generated. (If set incorrectly, the blue field against which the characters are normally
displayed may be gray. No real harm is done, but you may wonder why the picture keeps losing its color momentarily when on screen messages are displayed.)
Before adjusting your input defaults, we suggest turning the master volume down
to a relatively low level on your PAV (since you will be using strong signals to
calibrate the system’s input levels and don’t want to endanger your loudspeakers).
Then place the PAV into either THX cinema or pro logic mode (which engages
the reference level LED in the main display). The following sections outline the
various input defaults you may customize.
Tip:
Programming a New
On Screen Alias
You can go directly from normal operation to the input
default menu for a partcular input by pressing and holding
the input button for about five seconds. When finished,
pressing menu once will take you back to normal operation
without having to do any further navigation of the menu
system.
The PAV allows you to re-name its inputs for the purposes of the on screen
menus, for greater clarity and simplicity of subsequent use. These “aliases” (alternative, on screen names) may be up to five characters long.

When you use the volume +/– keys to select alias, the first character will

again to scroll through the available list of characters until you see what you
need. Then use the master button to move on to the next character. Continue until you are finished with this alias. For example, setting the cd 1
alias to “CDP” and then moving the cursor on with the master button
would result in a screen which looked like this:
ALIAS

PRESS ENTER TO SAVE THE NEW ALIAS
From now on, the on screen display will refer to this input as your “CDP”
(or whatever else you spelled out).
Repeat these programming steps in turn for any inputs which will be used in
your system’s configuration.
Programming Input Offsets
Having created a new alias for an input, pressing enter returns you to the
inputs defaults menu for that input. Pressing master moves the cursor on to the
input offset default for that source. The PAV will automatically load this number as
the input level whenever this particular input is selected.
The primary purpose for this feature is to eliminate the level differences between
various source components, in order to give the Dolby Pro Logic circuitry a more
consistent signal strength with which to work. For example, you may discover that
your CD player’s output is stronger than your laserdisc player’s output. The best
course is to set the input level adjustment for the laserdisc, since it will often play
surround-encoded material; then adjust the relative volume of the CD player to
match that of the laserdisc (in order to avoid abrupt changes in volume when
switching between inputs). While not especially critical to the operation of the
PAV, fine-tuning the input levels of the source components will yield some improvements in both dynamic range and signal to noise performance of surroundencoded material.
To adjust your default input offsets, access the input default menu for the selected
input by pressing and holding its button for about five seconds, then:

sources made on your tape decks or VCRs. (Note that the meters of analog
tape decks such as cassette decks should read -20 dB when recording and
playing back this signal.) Using the volume +/– buttons, adjust the input
level offset up and down as needed until you find the setting at which the
LED first illuminates.

PRESS ENTER TO SAVE YOUR NEW DEFAULT INPUT LEVEL OFFSET.
This setting will automatically be used whenever you select this input. You

Repeat these programming steps in turn for any inputs which will be used in
your system’s configuration.

The PAV also allows you to set up a preferred surround mode for each input,
which will be engaged automatically whenever that input is selected. For example, you might want to use stereo surround for most of your music listening.
As such, it would make sense to set that as your default surround mode for your
CD player and other music sources. Similarly, you would probably choose THX
cinema as your default for a laserdisc player. By doing so, you will automatically
be in the most appropriate surround mode the majority of the time, without having to pay any attention to it yourself.
Any surround mode may be assigned to each input. In addition, there is also a
choice given for none, which will leave the PAV in whatever surround mode it
happens to be in at the time of the input selection. (Note that none is not the
same as surround off which will force the PAV into two-channel stereo operation.)
When the PAV leaves the factory, all inputs use “none” as their default surround
mode, which leaves the PAV in the same mode all the time until you change it
manually.

PRESS “ENTER” TO SAVE THIS DEFAULT SURROUND MODE FOR THIS INPUT.
Repeat these programming steps in turn for any inputs which will be used in
your system’s configuration.
Programming Video Inputs
Video sources have the same input default options outlined above for audio
sources, with one addition: you need to tell the PAV whether you are using the
composite or the S-video inputs for each of your four video inputs. The very different nature of these two signals requires that on screen displays for each be
generated differently. (If set incorrectly, the blue field against which the characters
are normally displayed will be gray; also, color video will turn black and white
for the duration of on screen messages. No real harm is done, but you may wonder why you occasionally lose color.)
All video inputs are set to composite when they leave the factory. We strongly
recommend that you standardize on either composite or S-video and use your
choice consistently throughout the system. To use the S-video connection on the
PAV for a particular video input:

FROM THE SETUP MENU, SELECT INPUT DEFAULTS, FOLLOWED BY VIDEO

THEN PRESS EITHER OF THE VOLUME +/– KEYS TO TOGGLE TO S-VIDEO

PRESS ENTER TO SAVE YOUR CHANGE.
Repeat these programming steps in turn for any inputs which will be used in
your system’s configuration.
Mode Defaults
The PAV also allows you to customize its default configuration for each surround
mode. Although the most accurate reproduction will be achieved by leaving these
adjustments disabled, their inclusion does allow you the option of tailoring the
sound of various surround modes to suit your individual taste. For example, if
you find yourself turning up the rear speakers whenever you watch a movie, and
then turning them back down to their normal, calibrated setting for music, you
may want to set the defaults for THX cinema and stereo surround accordingly.
We recommend living with the PAV and using it in its calibrated
settings for a while before changing these defaults. There is an adjustment period people go through when their system is upgraded
during which it is difficult to make an accurate decision about
sound quality. The best-known example of this is when someone
first owns a high quality subwoofer: the tendency is to turn it up
too loud initially (so one can “hear it”); as time goes by, most
people find themselves gradually turning it down until it is adjusted to a more accurate level that blends appropriately with the
rest of the system. Similarly, there is a tendency to exaggerate the
bass and surround channels in surround systems before one adjusts to the multichannel experience.
Remember that ad hoc adjustments (to compensate for a poor recording, for example) on the PAV are easy to make. Simply touch the button for the speaker(s)
you wish to adjust, and then raise or lower the volume. These offsets from the
calibrated settings remain active until you deliberately change them, or until you
press recall to restore the PAV to its calibrated settings.
The surround mode defaults simply automate this process. For each of the six
surround modes of the PAV, you may create default offsets for center, rear, and
sub channels. The PAV will simply enter these default settings for you as it
switches from one surround mode to the next. As always, you may alter these settings as you see fit from the front panel or from the remote control. You may also
return to the calibrated (no offsets) setting by pressing recall.
In addition, you may elect to automate the sub on/off toggle described in the
section Programming the Remote Control. (Briefly, this toggle switches between
the speaker setup described in the set speakers menu and one in which the
front speakers are given a full range signal and the subwoofer is turned off.)
Setting Mode Defaults
To change the default offsets for your various surround modes, you must first enable this special feature for all six surround modes, then alter each as you like:
45
1
**DISABLED/
ENABLED**
FROM THE SETUP MENU, SELECT “MODE DEFAULTS” AND ENABLE THE

After selecting mode defaults from the setup menu, you will see a screen

You must first engage this feature by pressing volume +/– to toggle
-- DISABLED-- to --ENABLED--. This extra step ensures that any automated
changes of output levels are consciously chosen and therefore less likely to
cause surprise. It also allows you to disable all the surround mode defaults
in one easy step should you decide at some future date to return to the
calibrated settings for all your routine listening.

SELECT “NONE”, “ON”, OR “OFF” AS THE SETTING FOR YOUR SUBWOOFER
IN THIS SURROUND MODE
If you simply leave this setting as none for all your surround modes, the
PAV will always use the speaker settings from the set speakers menu. If you
prefer to add a subwoofer for movies and remove it when listening to music, you should set speakers for a biamplified system (crossover on), set the
movie-related surround modes for sub on, and set the music-oriented surround modes to sub off. This way, your subwoofer will automatically be engaged or disengaged as you change between (for example) THX cinema to
stereo surround.

ADJUST THE LEVEL OF CENTER, REAR AND SUB CHANNELS RELATIVE TO
THE FRONT LEFT AND RIGHT SPEAKERS TO SUIT YOUR PREFERENCE
Using the master button, move the cursor to the item you wish to adjust;
then adjust the setting with the volume ± buttons.
5
Programming the IR Input
PRESS “ENTER” TO SAVE YOUR CHANGES; REPEAT FOR ALL OTHER
SURROUND MODES AS NEEDED
Note that if you change only a single surround mode, the others will remains at their factory default settings of no offset and sub = none. This will
cause even offsets entered at the front panel to be reset to all zeros when
surround modes other than the one you changed are selected. (All the
more reason to live with the system for a while before electing to customize
it in this way. You should know your preferences with a fair degree of certainty before automating them to this degree.)
The infrared remote input jack on the rear panel of the PAV may be programmed
to respond to either local commands (e.g., duplicating the functionality of the IR
receiver in the main display) or remote commands (e.g., from an IR repeater, to
affect only the remote signal path). Refer to p. 19, Remote IR and Remote Turn-on,
for more information.
The factory default setting is remote. If your installation of the PAV prevents IR
commands from reaching the PAV (as when behind closed doors, for example),
and if you are using an IR repeater to pass IR commands to the PAV, you may
wish to set the IR input on the rear panel to local, in which case you would also
want to “hard-wire” the PAV to your IR repeater (see IR Tip Polarity, page 19). To
make this software change, follow these steps:
Important:
1
ENTER THE REMOTE CONTROL MENU
This menu is accessed from the setup menu by moving the cursor to
remote control (using the master button), and pressing the volume +/– key
to select the menu item.
2
SELECT REAR IR JACK
Using the master button, move the cursor to rear IR jack and press
volume +/–.
3
TOGGLE THE MENU ITEM FROM REMOTE TO LOCAL
Press either of the volume +/– keys to change the default setting of
remote to local.
Note that this change will not take effect until you back out of
the on screen menus and return to normal operation. This
delayed response allows you to continue to use the IR
receiver on the main display long enough to finish what you
are doing. It will be turned off in favor of the IR input jack
once you leave the menu system.
Once the rear IR jack is changed to local, the IR receiver in the main display is
deactivated in favor of the rear IR jack. If you do this unintentionally and are not
set up to “hard-wire” the commands into the rear IR jack, don’t worry. You can
always use the front panel buttons to operate the on screen menu system, turning the rear IR jack setting back to remote. Doing so reactivates the IR receiver in
47
the main display. (See Operating the On Screen Menus from the Front Panel,
page 35.)
Changing the
PAV’s IR Address
Important!
In some installations, you may discover that some other company is trying to use
the same infrared control codes used by the PAV, or vice versa. (This unfortunate
circumstance has become more common in recent years thanks to the explosion
of IR-controlled products in the home.) Fortunately, the PAV allows you to use any
of eight different sets of IR codes, which are accessed by changing the “IR address” used by the PAV.
If you change the IR address of your PAV, your remote control
will no longer operate the PAV until it is re-taught all of the new
codes! Do not change this setting from its default value of 5
unless you must, in order to solve a conflict.
If you run into an apparent IR conflict where pushing one button on a remote
control affects something seemingly unrelated, we suggest that you contact your
dealer/installer for assistance. (The numbers 0 through 7 refer to Philips RECS80
addresses, a bit of engineering trivia your installer may need if your system is
already using several of the available addresses, including the one we normally
use in the PAV: 5.)
Configuring the
Remote Trigger output
The remote trigger output on the rear panel of the PAV is normally used to automatically turn the associated Proceed AMPs on and off with the PAV. This is particularly convenient when the amplifiers are located at some distance from the
PAV, as may be the case when they are placed near the speakers (for example). In
this application, you can simply leave it in its default setting, pulse.
If you need to turn on and off a power amplifier that does not include remote
turn-on capabilities, the simplest solution is to use a product like the Niles IPC-6,
which is an intelligent AC-outlet strip that can turn AC power on and off to a set
of components based on the presence or absence of a level control voltage.
Caution!
If you use the remote trigger output of your PAV with nonMadrigal products, it is important that those products provide
current-limiting and ground isolation for this output. This
isolation may be accomplished with opto-couplers or with
low-voltage relays. Please consult with your installer prior to
using the remote trigger output with products other than those
designed by Madrigal.
Note that the remote trigger output of the PAV can support approximately 5 volts
at 30 mA current.
Having completed the calibration of your PAV system, you may also wish to consider locking your settings to minimize the likelihood of someone inadvertantly
changing your setup. This menu item can be found under the operate menu,
which is found at the main PAV menu. (See page 47 for more information.)
48
Using the PAV
Setting the Volume
There are, in effect, two volume controls in the PAV. When in either THX cinema
or pro logic modes, the input level control should be used to compensate for differences between recordings, using its associated green LED as a guide. Adjustments to allow for personal preferences, late-night listening, and the like should
then be made with the master volume control.
When in any of the other surround modes, the input level adjustment is significantly less critical and can be largely ignored (particularly if input level defaults
were set up during installation).
Home THX cinema
When the THX cinema mode is engaged, both the Dolby Pro Logic circuitry and
the proprietary Home THX audio processing circuits are in use. This is most appropriate for film-based program materials made since the mid-1970’s, which have
in all likelihood been mixed in a standard dubbing stage environment. This setting will provide the listener with the most accurate reproduction of the majority
of motion pictures available. In addition, many other video source materials are
produced in Dolby Surround using the industry standard response curves, and
are best enjoyed in the THX cinema mode. (Examples include Star Trek: Voyager
and The David Letterman Show, which are mixed in an environment which emulates the dubbing stage used for film.)
Dolby Pro Logic Surround
Some program material does not conform to film industry standards, although it
may still be Dolby Surround encoded. Music videos on MTV, for instance, are often Dolby Surround encoded, but have soundtracks which are produced in nonfilm studios. In fact, a growing number of music CDs are mastered with surround
sound. These sources and others which have surround encoding but which are
unlikely to have been mixed or re-mixed in industry-standard production facilities should use the pro logic mode to avoid compensation where none is indicated.
When in doubt as to whether THX cinema or pro logic is more appropriate, listen for a natural presentation of the treble. Films mixed for theatrical release exhibit an elevated treble region when played back on a home system with flat response. The THX cinema mode will correct this. Conversely, surround-encoded
programs without this high frequency emphasis might sound dull or lacking in
detail when (incorrectly) played in the THX cinema mode.
Stereo Surround
The stereo surround mode has been carefully designed to extract real ambience
from your recordings rather than synthesizing something artificial that might be
quite alien to the music itself. The ambient cues found in the program material
are then used to provide appropriate information for the center and rear speakers.
The front Left and Right speakers are left unaffected by this mode, allowing you
to hear unadulterated stereo imaging with the addition of a genuine sense of hall
ambience.
Since this mode is based on the recordings themselves, it is normal to hear some
variation in the degree of the effect. Extremely “dry” recordings which lack any
significant ambience may not sound significantly different than when in surround
49
off mode (e.g., two-channel stereo). You may find that increasing the level of the
rear speakers is necessary in order to bring what little ambience is in a “dry” recording up to a more enjoyable level.
Mono Surround
The mono surround mode can provide a sense of spaciousness and size to
monophonic program material such as some historical recordings and movie classics such as Casablanca or The Wizard of Oz. The mono surround mode makes
no effort to “electronically reprocess to simulate stereo” (a process which almost
always causes more harm than good). Instead, it uses sophisticated steering techniques to create a sense of space in what would otherwise be a largely dimensionless soundfield. It is particularly helpful when viewing mono program material on a big screen, where a tiny mono image would simply sound wrong in
contrast to the big picture.
Surround Off
The surround off mode is intended for music reproduction without any form of
surround enhancement. In this mode, the Left and Right speakers are active along
with the subwoofer(s), and reproduce the input without any processing other
than the electronic crossover needed for the subs.
Mono
The mono mode sums the incoming Left and Right signals. The result is sent to
the center channel speaker, as well as the subwoofer(s). This mode is especially
useful for older, classic films or historical recordings which have noisy mono
soundtracks. Since much of the noise is likely to be random in phase, significant
noise cancellation can often be achieved by playing these mono sources in a true
mono mode.
The Operate Menu
Those settings for which there is no “right” or “wrong” but which are purely a
matter of user preference are contained in the operate menu (accessed from outside the menu system by pressing menu on your remote control twice). The operate menu is organized as shown at left, and is detailed below:
MUTE

DISPLAY
PREF
OPERATE
VOLUME

• mute level — the magnitude of volume reduction introduced by pressing
the mute key is user-definable from -5 to -110 in increments of 5 (-2.5 dB to
-55 dB in 2.5 dB increments). The factory preset is for -40 (-20 dB).
• display pref — the display preferences subheading groups together several
items which control the appearance of the on screen displays presented by
the PAV during use. We will cover to this menu item in detail on the next
page.
• volume display — gives you the option of displaying your volume settings
on a scale of 0 (off) to 112 (extremely loud) or on a scale which is marked
off either plus or minus around the calibrated reference level established
during calibration. The former is called “absolute” while the latter is called
“relative.” As an example, if your calibrated reference level is 91, the display
would read 0 in the relative mode when it would read 91 in the absolute
mode.
• volume speed — you may select either slow, medium, or fast response for
the volume change when pressing and holding the volume +/– keys. In all
cases, single taps of the volume keys result in single incremental steps in
volume. The volume speed chosen affects the amount of time it takes to reach
maximum speed while holding the volume +/– button down.
• setup: locked/unlocked — after having completed all setup adjustments,
you may wish to lock your settings to prevent accidental changes. Doing so
will disallow access to the main setup menu until unlocked.

Returning to the subject of display preferences, selecting this menu item (by
pressing either volume +/– while the cursor is pointing at it) presents you with a
sub-menu, outlined at left. The details of that submenu are as follows:
• display position — the position of the on screen display of volume
changes, surround mode changes, etc., can be moved up or down to
suit the needs of your system. This flexibility allows you to place your
PAV’s on screen information where it won’t conflict with other on
screen information. As an example, you may place the on screen display in the black area under letterboxed movies.
• display timeout — controls the duration of these on screen “updates”
generated by the PAV as status reports when you change something.
(Remember that you can disable the on screen display using the on
screen button on the remote control.)
• character style — on screen messages are normally displayed within
a black box when superimposed on live video signals. This display
method ensures legibility even against extremely bright backgrounds,
when white letters might otherwise be difficult to read. At your option, however, you may elect to have these superimposed messages
displayed with only a black fringe around them, which some may find
less intrusive than the black box. This method remains easily legible
in all cases except a few (relatively rare) examples of extremely bright
video. A case in point might be the seemingly endless pans across the
sky shown during broadcast golf tournaments. (Do they really think
we can see a tiny white ball flying across a cloudy sky?).
• background color — the default color for the screen when lacking a
live video signal to display is blue. This blue screen serves as a reminder that your television is on, when in fact you may prefer to turn
it off. However, some may prefer to leave their projection television on
in order to keep it warmed up and ready to use, in which case a
black screen might be more desirable. (A black screen would facilitate
listening to music in a darkened room, for example.) This menu item
allows you to choose the best mode for your system, either blue or
black.
51
Programming the Remote
Control
Programming Other
Components’ Functions
The remote control provided with the PAV is capable of learning the commands
of almost any other remote control. This is true of any and all buttons on the remote, including those that are pre-programmed from the factory to operate specific PAV functions. If you find that some other configuration of the PAV remote
control better suits your particular needs, you are free to assign any command to
any button.
Chances are you will want to leave the pre-programmed functions of the remote
control where they are. The first order of business will be to teach the remote
control the critical functions of your other remote controls so you can put them
safely away in a drawer somewhere (reducing the clutter on your coffee table).
Before teaching the PAV remote control new commands, it is a good idea to organize your thoughts regarding which commands you would like to teach it, and
which buttons are the most logical “locations” for those commands. (See Planning Your Remote Control, pp. 55-56.)
For example, you may want to group the commands for your most-used components (perhaps your CD player and your TV) on the same bank as the PAV commands. Doing so minimizes the need to switch to the other bank.
Once planned, actually teaching the PAV remote the new commands is simple.
Follow these steps:
52
1
USING A PEN OR SIMILAR OBJECT, PRESS USE/LEARN.
This action places the remote control in the Learning mode, indicated by
the ready to learn and the learned/sending lights both being lit. Whenever
you wish to return to normal use mode, you may press the use/learn button again.
2
PRESS THE BUTTON WHICH IS TO RECEIVE A NEW COMMAND
This button becomes the “destination” for the command you are about to
“send” to the PAV remote control from the other component’s remote.
3
WITH THE OTHER REMOTE POINTING INTO THE PAV REMOTE CONTROL’S
IR WINDOW, PRESS AND HOLD THE COMMAND TO BE LEARNED FROM
THE OTHER REMOTE
Note that the PAV remote’s IR window is on the left side of its front surface
as seen from the normal user’s position. The PAV remote control will “receive” the IR command from the other remote and learn it, indicated by the
learned/sending LED lighting for a few moments. When this occurs, you
may release the button on your other remote.

REPEAT THE PROCESS OF “TEACHING” NEW COMMANDS TO THE
VARIOUS BUTTONS ON THE PAV REMOTE CONTROL UNTIL FINISHED.
You may, of course, add additional commands at any time. Just be careful
not to assign two commands to the same button (in the same bank), as
this will cause the second command to overwrite the first one, making it
unavailable for use.
5
PRESS “USE/LEARN” AGAIN WHEN YOU ARE DONE, IN ORDER TO
RETURN TO NORMAL “USE” MODE
You may now use your PAV remote control in place of the one you just
used to teach the PAV remote its “new tricks.” In the normal use mode, the
PAV remote control will transmit the various commands it has been “taught”
to associate with particular buttons, allowing you to put away the other remote.
6
TEST ALL YOUR NEW “LEARNED” COMMANDS TO ENSURE THAT THEY
WERE “LEARNED” CORRECTLY
As with all learning remote controls, it is sometimes possible for the PAV
remote control to learn either partial or multiple command bursts from the
original remote control. If you experience unexpected behavior when using
the PAV remote in lieu of the original, simply re-teach the offending command. You may want to try either a quick tap or a more extended press of
the original remote control’s button in order to get it to send a complete
(but not redundant) control signal for the PAV remote control to learn. Try
to avoid brightly lit areas, or areas lit by strong flourescent lights, when
teaching any learning remote control new commands. If it is impractical to
dim the lights a bit, provide some shade between the remotes by holding
this owner’s manual (or something similar) over the remote controls while
teaching new commands.
53
Programming PAV Functions
If you inadvertantly overwrite one or more PAV commands in your PAV remote
control, never fear—you don’t have to obtain another PAV remote in order to reteach your own its PAV-specific commands. The PAV itself can send all of the necessary IR commands from its main display window, enabling you to teach the
PAV remote both its pre-programmed commands and a few other, optional commands which you might find useful.
When using the PAV itself to teach new commands to your remote control, your
remote will have to be in its learning mode (obviously). Therefore, you must
navigate the on screen menus by using the buttons on the front panel of the PAV.
The buttons on the front panel you need to use are as follows:
• recall: the menu function is provided by the recall button. In order
to activate the on screen menus rather than simply recalling the
calibrated output level settings, press and hold the recall button until the front panel lights are turned off (about ten seconds). From
this point on until you exit the menu system, the recall button will
perform exactly as the menu button on the remote control would.
• master: the front panel master button is also conveniently placed
adjacent to the volume +/– buttons, and serves the same purpose
as the one on the remote control.
• volume +/–: the front panel volume +/– buttons also operate in
the same fashion as their counterparts on the remote control.
• standby: the enter function is provided by the standby button on
the front panel (when the PAV is in menu mode). It is deliberately
set apart from all of the other menu-related buttons to make permanent changes of system parameters a deliberate act.

For example, you may find that you use the THX cinema, pro logic,
stereo surround and surround off modes most frequently. You could assign a
button to each of these and never have to cycle through the other options
again. Similarly, you could assign specific output paths to the e, f, g, and h

“off” commands for standby and mute (rather than toggles) offer improved
control over the PAV when operated from a remote zone.
The Surround, Path and Misc Control menus under the Direct Access
menus are as follows:

circuitry on and off independently of the remaining THX cinema circuits
(decorrelation and timbre-matching, both affecting only the surround channels). Since a small number of movies have already had their boosted high
frequencies corrected in the transfer to video, toggling the Re-EQ circuit off
prevents redundant correction while retaining the surround-channel benefits of THX.
Direct Volume provides a method for directly accessing any two-digit vol-
ume setting, something that owners of home automation systems such as
AMX and Crestron can use in their macros. For example, a macro called
“Background Music” might be written that would
•

select a particular music program on a 100-disc CD changer;
select cd1 on the PAV;
select stereo surround;
and change the volume setting to 45 (regardless of where the volume
had been set previously).
The format for giving the direct volume command is as follows: direct volume, then two digits, then enter.
The sub on/off feature will toggle between the configuration established
during initial setup and using the front three loudspeakers full-range, without any help from the subwoofer(s). (Specifically, it turns off the crossover
and the subwoofer output when subwoofer off is selected.) This feature
may be used to compare the performance of the system configured with
and without the subwoofer(s). (Note that pressing recall will always return
the system to its calibrated setup configuration, regardless of its current status.)

Planning Your Remote Control
For your convenience, we have included the following form on which you may
plan which additional functions you will assign to which buttons on the PAV remote control. We suggest photocopying this page and then planning your programming before getting into it too heavily. A little time spent planning can make
the teaching process go much more smoothly, and it provides you with a ready
reminder of which commands you placed where during the first day or two of
use. After that, you will probably find everything to be second nature, and you
may wonder how you ever got along without this “all-in-one” remote control. An
asterisk (*) indicates buttons normally used by the PAV.

Room Acoustics
The following information on room acoustics does not need to be considered in
every installation. Rather, it is provided for those who plan a dedicated listening
room, or for those who feel they have a problematic room and therefore need
ideas about how to improve their system’s performance further.
Once again, the value of your dealer’s experience should never be underestimated. Many installers have been involved in dozens or hundreds of home theater installations similar to yours, and have proven solutions to whatever problem
you might be experiencing. The information provided here is best used as a
starting point for your discussions with your dealer.
Room Reverberation
In a perfect world, your room would have no characteristic sound of its own, no
acoustical “fingerprint.” The ideal room would be perfectly neutral and would not
superimpose itself on the sound within it in any way. After all, any reverberation
or ambient sound which the director wished people to hear will be recorded in
the soundtrack. And much of the inherent ambience in music recordings will
normally be reproduced by the rear speakers (using the stereo surround mode),
where such ambience belongs. Anything beyond this added by the room would
be redundant and would actually detract from the realism. In general, then, the
ideal listening room will be somewhat more “dead” acoustically than the average
living room. This goal can be accomplished through the use of drapes, plush carpeting, or various acoustical treatments.
Note, however, that the surround speakers depend on reflecting sound to develop
the proper enveloping characteristic, and that they therefore need some reflective
surfaces. Ideally, these would be diffusive in nature, providing randomized reflections in many directions. Bookcases and other irregular surfaces provide diffusion, as do some commercially-available wall treatments. If there is some degree
of choice in the matter, it is generally better to have the rear 1⁄3 of the room be
reflective and diffusive, while the front 2⁄3 of the room is relatively absorptive. Resist the temptation to “go overboard,” however, lining the room with absorptive
material from floor to ceiling. It is possible to have too much absorption, resulting
in reduced subjective dynamic impact and therefore less excitement.
The Boundary Effect
A well-known effect of room acoustics is the change in bass and mid-bass response which results from moving a speaker near a wall. This so-called “Boundary Effect” is the result of the reflection of the extremely long bass wave off the
wall being substantially in-phase with the direct sound radiated toward the listener. This in-phase reinforcement effectively “doubles-up” on the amplitude of
the bass relative to what would have been heard without the wall reflection. If a
speaker was originally designed to produce flat response when situated in the
middle of the room (not near any room surfaces), placing it on the floor or
against a single wall often makes it sound somewhat bass-heavy. Placing it where
the floor and the wall meet will produce even more bass, and placing it in the
corner (at the intersection of three room surfaces) is enough to make almost any
speaker sound congested and muddy, unless it was specifically designed for that
type of placement in the first place. (In practice, the actual difference you hear
may vary slightly from room to room, depending on how solidly the walls are
built. A light, flexible wall may “leak” bass into the next room, reducing the magnitude of the effect.)
59
The Boundary Effect is particularly important when it comes time to position the
front speakers. If they are not placed consistently with regard to adjacent room
boundaries, the tonal balance or timbre of sounds panned across the front may
change, weakening the illusion of a real object moving across the soundstage. The
front Left, Center and Right speakers should be the same distance from the wall
behind them, and there should be approximate symmetry of the Left and Right
speakers with respect to their respective side walls.
Room Modes
Another acoustic property of concern is the concept of “room modes.” (These are
also sometimes called “standing waves.”) Bass frequencies have long wavelengths,
some of which are the same size as some dimension of the room itself. If the
sizes work out such that the reflection of the wave between two walls is in phase
with the original wave, that particular frequency will be over-emphasized. Similarly, some frequencies will very nearly cancel out in certain parts of the room,
being out of phase with each other. This effect is much worse in rooms in which
two or more dimensions (width and length, for instance) are even multiples of
one another, since the same frequencies are then being affected no matter which
way they turn. The result is wildly irregular bass response in various parts of the
room, resulting in either an unnatural, boomy quality or a thin, lifeless character
to the sound depending on where you sit.
All rooms have room modes, but you can ameliorate their effect greatly. In the
case of new construction, where you may have some latitude specifying the final
room dimensions, make sure that no two dimensions of the room are even multiples of each other. (Consult with your dealer for more information.)
Most of the time, you will not have the luxury of specifying where walls should
go. The next best thing (and something to be tried even when you can move
walls) is mid-bass diffusion. Break up the reflections between parallel surfaces
with large pieces of furniture or almost anything else. The worst sounding rooms
are the ones which are almost empty, since the standing waves can bounce back
and forth unimpeded.
Another strategy to be tried in minimizing the audibility of standing waves is
speaker placement. The placement of the speakers in any home theater system is
somewhat restricted by the need to have the sound closely associated with the
screen, which in turn must be in a location convenient to the seating area. But
sometimes moving a speaker a bit can make a noticeable difference in the
smoothness of the mid-bass response, due to changes in the room’s modes. Fortunately, the subwoofers can be moved with relative freedom, since they normally
will not be localized as sources of sound. Experiment with an ear toward having
the smoothest bass response and the best “splice” or transition to the LCRs.
Of course, there are various acoustical treatments which can be utilized—ask
your dealer. There is also electronic equalization, but this is best done after everything else has been optimized. Electronic EQ is best for providing the finishing
touches to a room, rather than for doing major surgery. And in all cases, electronic EQ should be done by a trained professional with equipment having at
least one-third octave resolution. Anything less than that is likely to introduce as
many problems as it solves.

Your System Settings
The settings in your Proceed PAV are saved in non-volatile memory and should
normally survive power outages. Still, it is a good idea to write your preferred
settings down against the chance of an inquisitive neighbor or family member
changing them without your knowledge. Please use the following form to record
your system’s settings against such a possibility.

Troubleshooting
Your Proceed PAV has been designed to deliver many years of satisfaction. It has
also been designed to allow an unusual amount of “customization” so as to make
it suitable in a wide variety of (possibly changing) circumstances. This flexibility
necessitates a certain amount of setup before the unit can be expected to perform correctly—in effect, one must inform the PAV of its environment so it may
make the right “decisions” about what it should do. Once setup is completed, the
PAV is quite simple to use. But the setup is quite essential.
It has been our experience that most difficulties encountered with the PAV are
due to improper initial setup. Please review the relevant portions of this manual
for the details of the setup procedure.
THERE SEEMS TO BE TOO LITTLE (OR TOO MUCH) BASS.
✓ Is the crossover set correctly for your speaker configuration?
✓ Are the output levels set accurately, usinga dB SPL meter?
THE AURAL IMAGE SEEMS INCONSISTENT OR VAGUE
✓ Are the output levels set accurately, using a dB SPL meter?
✓ Are your speakers closely matched to one another in tonal balance
and dynamic performance?
THERE IS A PERSISTENT HUM IN THE SPEAKERS.
✓ If it exists only with a particular input, check that source component and its interconnecting cables.
✓ If it exists on all sources, you may have a ground loop by having
multiple ground references in your system. We suggest you ask
your dealer for assistance in isolating this problem.
MY PAV’S ON SCREEN DISPLAY HAS INDICATED THAT IT HAS DETECTED
POTENTIAL AC PROBLEMS AND REFERRED ME TO THIS SECTION OF THE
MANUAL.
✓ If this is the first time you have seen the message, you probably
don’t have to do anything. If the PAV detects an electrical problem
that might affect its operating software (an unusually strong spike
on the AC line, for example), it posts this message and reinitializes
itself automatically. Your user settings, output levels and so forth are
retained.
✓ If you see this message with any regularity, you may have a persistent, severe ground loop or other AC problem that should be fixed.
We suggest you ask your dealer for assistance in isolating this
problem.
I LEFT THE PAV ON, BUT JUST RETURNED AND FOUND IT IN STANDBY.
WHAT IS HAPPENING?
✓ There was probably a power outage while you were away from the
system. During a power failure, the PAV saves all of its critical settings to non-volatile memory. When power is restored, it enters the
standby mode and waits for your return.
64
Care and Maintenance
To remove dust from the cabinet of the PAV, use a feather duster. To remove dirt
and fingerprints, we recommend isopropyl alcohol and a soft cloth.
Caution!
Always apply the isopropyl alcohol to the soft cloth and then
wipe the PAV with the dampened cloth. Never pour or spray
even small amounts of any liquid directly on the PAV, as doing
so may allow the liquid to reach the circuitry inside the unit.
Any liquid inside the unit poses a hazard to both the user and
to the unit, and must be avoided.
Make sure that the Remote sensor window on the front panel and the Remote
Control’s projection lens are kept clean and dust-free.
Fluorescent lighting and sunlight may interfere with the operation of the Remote
Control. Avoid placing the PAV near fluorescent lamps or in direct sunlight.
When the Remote Control’s batteries need to be replaced, use only AA batteries;
always replace both batteries at the same time. If you don’t plan to use the Remote Control often, remove the batteries. When not used for an extended period,
even “leakproof” batteries can leak corrosive acids that will damage the Remote
Control (and will void the warranty).
65

Obtaining Service
We take great pride in our dealers. Experience, dedication, and integrity make
these professionals ideally suited to assist with our customers’ service needs.
If your Proceed component must be serviced, please contact your dealer. Your
dealer will then decide whether the problem can be remedied locally, or whether
to contact Madrigal for further service information or parts, or to obtain a Return
Authorization. The Madrigal Technical Services Department works closely with
your dealer to solve your service needs expediently.
Important!
Return authorization must be obtained from Madrigal’s
Technical Services Department BEFORE a unit is shipped for
service.
It is extremely important that information about a problem be explicit and complete. A specific, comprehensive description of the problem helps your dealer and
the Madrigal Technical Services Department locate and repair the difficulty as
quickly as possible.
A copy of the original bill of sale will serve to verify warranty status. Please include it with the unit when it is brought in for warranty service.
Warning!
All returned units must be properly packaged (preferably in
their original packing material), and the proper return
authorization numbers must be marked on the outer carton
for identification. If the packaging to protect the unit is, in our
opinion or that of our dealer, inadequate to protect the unit,
we reserve the right to repackage it for return shipment at the
owner’s expense. Neither Madrigal nor your dealer can be
responsible for shipping damage due to improper (that is,
non-original) packaging.
Your dealer can order a new set of shipping materials for you if you need to ship
your component and no longer have the original materials. There will be a
charge for this service. We strongly recommend saving all packing materials in
case you need to ship your unit some day.

Specifications
The correlation between published specifications and performance is unreliable. A
list of numbers reveals virtually nothing. All technical measurements must be subject to qualitative as well as quantitative interpretation.
Measurements of the PAV yield excellent results by any standards. However, only
those specifications that apply to its actual operation are included here.
