FIRST STEPS / BASIC INFO
UNPACKING THE CONSOLE
The console is shipped as two packages. One (larger) carton contains the
console and technical documentation; the other (smaller) contains the
rackmount power supply, connecting cable, and connector kit.
MAINFRAME INSTALLATION
DO NOT CONNECT THE R-5 CONSOLE TO ITS POWER SUPPLY, AND DO
NOT CONNECT THE POWER SUPPLY TO THE AC POWER LINE UNTIL
INSTRUCTED TO DO SO.
It is not necessary to prepare the counter by making a cutout, since the
R-5 is mounted above the counter top. If you will be securing the console
to a counter top, you will need to drill mounting holes for four #8
woodscrews as shown in the drawing below.
30.3"
Pre-drill for #8 woodscrews—do NOT use larger diameter screws; they may split the console wood!
Drill COUNTERTOP with .173" diameter (#17 drill) clear holes. Pre-drill CONSOLE WOODEN
ENDPIECES from below with .136" diameter (#29 drill) tap holes. Use hole locations as shown.

FIRST STEPS / BASIC INFO
The first step is to ground the console.
SYSTEM GROUND
While console power supply common, audio common, and the
mainframe chassis are connected together at the R-5 mainframe, they
are not connected to electrical ground and the chassis of the power
supply. Safety requirements dictate that a positive connection from the
console mainframe to electrical ground be made in the completed
installation; audio requirements also dictate this same connection—
use the two grounding lugs on the connector surface area of the
mainframe (underneath the hinged meterbridge) to establish your system
ground (see left AUD VU meter area on drawing on page 1-1).
The system ground serves two important purposes:
(1) Provides a zero signal reference point for the entire audio system;
(2) Assures safety from electrical shock.
There exist two terms that one encounters in a discussion of ground:
(A) EARTH GROUND, which is usually a heavy copper rod driven
into the soil adjacent to the building (around 6 feet down) or
a connection to the copper water pipes leading into the
building. Either is acceptable (unless, of course, the water
pipes are plastic).
(B) THE POWER COMPANY EARTH CONDUCTOR that enters the
building at the power line breaker box; this conductor should
be (and is often by code) tied to the above-mentioned earth
ground at one point. This point is the SYSTEM EARTH
GROUND.
TIE THE CONSOLE GROUND LUG TERMINALS TO THE SYSTEM
EARTH GROUND. TIE EVERY PIECE OF EQUIPMENT IN THE ENTIRE
AUDIO SYSTEM TO THE CONSOLE'S GROUND LUG TERMINALS. If the
system earth ground point is inaccessible, tie the console ground
terminals to the power company earth conductor at the main breaker box
(see drawing "Typical Grounding Scheme" on page 1-4).
Each piece of equipment should be connected by its own ground wire
(usually the round third pin on the AC cord). This means that every AC
outlet must have a separate conductor run to the console ground lug
terminals; the outlets cannot be daisy-chained as is normally encountered
in commercial and residential AC systems. Any equipment not supplied
with 3-wire AC cables must have individual ground wires (16 gauge or
larger) connected to their chassis grounds and then run to the console
ground lug terminals.

GROUNDING SCHEME
Further Grounding Details
As a rule of thumb, consumer
units (low level, –10dBu,
unbalanced) usually utilize RCA
jacks and two conductor wiring
connections; professional level
equipment (+4dBu, balanced)
generally uses three-conductor
XLR connectors.
R-5 / Jan 97
Check all equipment to be absolutely certain that each unit is power
transformer isolated from the AC mains to prevent safety hazards.
It is assumed that in each piece of audio equipment the audio ground
and the chassis are tied together at some point. Any piece of equipment
lacking a grounded chassis is likely to be prone to interference problems.
Locate all unbalanced audio equipment in the same rack if possible, to
minimize chassis ground potential differences. It may also be helpful to
insulate each piece of unbalanced equipment from it’s mounting rails in
the rack by means of nylon 10-32 screws and insulating washers between
rails and faceplates.
Page 1 - 4
FIRST STEPS / BASIC INFO
The next step is to install the rackmount power supply.
THE CONSOLE POWER SUPPLY
The power feed recommended
in the text is often installed and
referred to in studios as an “isolated AC ground” outlet.
It is usually orange in color.
The R-5 console uses a separate rackmount power supply unit. The
power supply should be mounted in an adjacent equipment rack within
fifteen feet (but no closer than 3 feet) of the console. It should be
mounted in a rack space (it requires two rack spaces or 3-1/2") where
proper air circulation is possible. Avoid locating any high gain equipment
(such as phono preamps, tape recorders, etc.) too near the power supply,
to avoid magnetic interference into that equipment.
Once the supply is mounted, connect the linking power cable at the
console end; the connector is a 6-pin plug that mates with a matching
socket ("DC IN") mounted on the console connector area underneath the
righthand end of the hinged meterbridge (see drawing page 1-10).
Connect the other end of the cable to the rear of the rackmounted power
supply.
The power supply is fitted with a 3-wire grounded AC cord that should
be plugged into a “clean” AC power source. That is, an AC source that
feeds only the control room audio gear. This source should be a separate
feed from those powering lighting, air-conditioning, or any other nonaudio machinery. The third pin ground wire of the AC source should be
tied to the system earth ground point (see “System Ground” section).
Note that while the AC power cord ground wire terminates at the power
supply chassis, it does NOT connect to the R-5 console common; the
console itself must be grounded separately. (See previous section:
“System Ground”.)
ENERGIZING THE CONSOLE
Assuming the console mainframe is properly installed and grounded,
and its power supply correctly rackmounted and connected to the
console, you may now energize the rackmount power supply by plugging
it into the AC mains.
The four LEDs on the power supply front panel should light up to
indicate the presence of their respective voltages. The console's VU
meters and timer display will illuminate. All other switches should
alternate on and off when pressed in succession. (Note CUE switches will
de-activate when an associated line input red channel ON switch is
pressed. Amber channel OFF switches should deactivate ON switches
when pressed.
Once you have verified proper power-up, unplug the rackmount
power supply to de-energize the console.
You are now ready to proceed with audio and control wiring. First,
however, you should familiarize yourself with the R-5 wiring system
and supplied tools (next section).

FIRST STEPS / BASIC INFO
WIRING OVERVIEW
All audio/control connections and end-user programming of R-5 console
functions take place at 12-pin AMP-type connectors located along the top
of the console, directly underneath the hinged meterbridge (see top of
drawing on page 1-1). Each connector consists of a printed-circuit board
("PCB") mounted female socket and a supplied mating male plug.
All R-5 console wiring takes
place at the top of the
console, underneath the
hinged meterbridge.

being inserted into its PCB-mounted socket.
The supplied crimp tool (with extractor pin) is used
to wire up all I/O connector plugs.
A connector kit is included with each console, and consists of mating
plugs, a crimp tool (Paladin model PA1645), an appropriate number of
crimp type wiring pins (.062" pin diameter; to be used with 22 gauge wire)
and a pin extractor tool (used to remove crimp pins that have been
accidentally inserted in the wrong connector block hole, or if rewiring or
wiring repair is needed).

FIRST STEPS / BASIC INFO
Individual Channel I/O Connectors
Console input channels each have two 12-pin connectors: UPPER (for
LOGIC and control) and LOWER (for AUDIO). Note that audio signal
connections follow a logical pattern: They are grouped in 4 sets of 3 pins
each (1-3, 4-6, 7-9, and 10-12). The first pin of each group (1, 4, 7, and 10)
is audio common (ground) for connection of shields. The next pin (2, 5, 8,
and 11) is the low side for balanced signals, or ground for unbalanced
signals. The third pin (3, 6, 9, and 12) is the high side for balanced signals,
or the signal connection for unbalanced ones.
The audio signal pattern described
in the text applies to input channel
AUDIO (lower) connectors. Logic,
output, monitor and accessory
connectors have their own pinouts.
See appropriate manual chapters
for detailed information. In all cases,
however, the pin numbering pattern
(1-12) is identical.

FIRST STEPS / BASIC INFO
BALANCED vs UNBALANCED CONNECTIONS
As a rule of thumb,
consumer units (low
level, –10dBu, unbalanced) usually utilize RCA
jacks and two conductor
wiring connections;
professional level equipment (+4dBu, balanced)
generally uses threeconductor XLR connectors.
By now everyone knows (or should know) that balanced inputs and outputs are
highly desirable —they have an intrinsic ability to reject hum, noise, crosstalk,
and RF, even if the shielding and grounding leave something to be desired. The
R-5 console has electronically balanced inputs and outputs, and leaves the
factory ready to accept professional level, +4dBu balanced source signals.
Not all equipment used in stations is balanced, however, and the most costeffective devices often don’t have +4 dBu output levels, either. Because of these
realities, the R-5 console is designed to accept balanced or unbalanced sources
with levels as low as -10dBu. If you will be using this type of equipment, be aware
that line input gain for affected channels should be reprogrammed for low level
–10dBu signals (see bottom of page 3-4 and top of page 3-5).
Connecting unbalanced inputs is simple—wire to the console with typical
shielded two conductor cable (like Belden 9451), just as if you were connecting
a balanced source. At the unbalanced machine’s output, connect the black wire
(LOW) to the shield. This “pseudo-balanced” connection has proven to be the
simplest and most trouble-free way to go. Another plus is that the wiring need
not be changed out if a balanced output machine is subsequently installed in that
position.
If you will be connecting console OUTPUTS to an unbalanced system, be sure
to connect the LOW side and SHIELD together at the console, and connect the
unbalanced system to the HIGH side output and LOW/SHIELD connections.

FIRST STEPS / BASIC INFO
WIRING UP THE CONSOLE
With the console mainframe installed and properly grounded, and the
rackmount power supply installed, connected, and console power-up
verified, you are now ready to proceed with audio and control wiring.
Note the main portion of this manual is organized by channel type
(inputs, outputs, monitors and accessories). Each chapter has a special
section devoted to wiring hook-ups; use the information in these sections
(typically called "Audio Connections" and "Logic and Control Wiring") to
proceed.

MONO MIC INPUTS
OVERVIEW
!
If you plan to use an outboard
patch loop, the console's internal
jumper resistor must be removed.
See page A-7.
Each R-5 audio console is supplied with two mono microphone input
channels; each channel can accept two microphone input signals which
are accessed by an A/B input selector switch at the top of the channel. There
are individual microphone gain trims provided for each A and B input,
allowing you to match differing signal levels.
Typically the two microphone channels will be used for the operator's
control room mic and a second microphone in another studio; for this
reason the channels may be programmed to automatically mute control
room or studio monitor speakers (factory preset to dim instead of mute see page A-10) when they are turned on, to prevent microphone feedback.
Mic inputs may also be turned ON and OFF from a remote location, allowing
talent in remote studios to control their microphones directly. It is also
possible to activate TALKBACK-to-CR from another studio.
As you can see by the signal flow diagram below, a pre-fader, pre-on/off
insert point is provided for mic inputs, allowing you to use outboard signal
processing (equalization, reverberation, compression/limiting, etc.) for
individual channels. Note this patch point is bridged at the factory with an
internal 10Ω resistor; if you will be using an outboard processing loop, the
jumper resistor must be removed. See page A-7.
Once they have passed through the channel's fader, microphone input
signals are assigned to the console's output busses: PROGRAM (stereo),
AUDITION (stereo) and/or TELEPHONE (mono).

CONTROLS and FEATURES
GAIN TRIM - Concealed front panel gain trim potentiometers (located
just above the A/B selector switch, beneath the hinged meterbridge) provide
a 32dB control range, assuring compatibility with various input levels.
There are separate trimpots for A and B sources.
A/B SOURCE - This switch (LED illuminated) selects between the two
electronically balanced microphone level inputs. The "B" source is selected
when the switch is lit.
INSERT POINT (internal) - Mono mic inputs have a patch point available
at the channel's audio connector to allow insertion of outboard processing.
The insert point is unbalanced, pre-fader, pre-on/off.
ASSIGN - These three switches (LED illuminated) determine where the
input signal will be sent; they route the channel signal to the console's
stereo Program (PGM), stereo Audition (AUD) and/or mono Telephone
(TEL) busses.
FADER - Long-throw carbon; plug-in for easy service.
ON/OFF SWITCHES - Turn the channel ON and OFF. Brightly illuminated.
If desired, they may be remotely controlled and programmed for different
automatic functions:
EXTERNAL CONTROL - Microphone channels may be turned ON and
OFF from a remote location; A TALKBACK-to-CR function can also be
remotely activated. The channel's ON switch can control a remote LED
tally indicator (see ON TALLY, bottom of page 2-5). These functions are
intended for a user-provided talent/guest control panel in a separate
studio. Three momentary contact switches are required (see drawing on
page 2-6).
PROGRAMMABLE FUNCTIONS - These include control room MUTE,
studio MUTE/DIM, and TALKBACK-to-STUDIO. These are programmed
via jumpers at the channel's logic connector (see page 2-5). Note the CR
MUTE signal can also activate the console's ON-AIR TALLY RELAY (see
MONITORS chapter, CUE/TALLY connector pinout, page 6-6).

Mono Mic Input (Audio Connections)
Mono mic input channel audio connections are made at the channel's
LOWER 12-pin AUDIO connector. These consist of electronically balanced
inputs for two microphones (A and B, pins 1 thru 6) and an unbalanced
mono patch insert point (pins 7 thru 12).

The R-5 console will accept balanced, low impedance (150Ω nom.)
microphone signals up to -12dBu levels. Individual gain trims for A and B
sources (each with a 32dB range) allow you to match various incoming
signal levels (with a typical -50dBu mic source signal, the resulting input
gain trim range will be -12dB to +20dB). Maximum deliverable mic gain is
85dB. Phantom power (+18V) is built-in. (While this is rarely necessary,
phantom power can be disabled if required—see Appendix, page A-4).
Mic channel insert points are unbalanced (nominal level -2.5dBu,
nominal insert out impedance 100Ω; insert in 10KΩ) and are intended for
outboard signal processing (equalization, reverb, digital processing, etc.).
If you will be using unbalanced equipment at these ports, be sure to tie LOW
and SHIELD together at the source end of each patch.

If you do plan to use an insert patch point as an outboard processing
loop, you must remove the console's built-in jumper resistor on the MB-5
Motherboard PCB (see APPENDIX, page A-7); otherwise signal will not pass
through your external equipment. If you will be using an INSERT OUT port
as a DIRECT OUT feed to another input, without bringing the signal back
into the channel's INSERT IN port, the built-in jumper resistor should
remain in place to preserve the signal path through the input channel.

MONO MIC INPUTS
Mono Mic Input (Logic and Control Wiring)
See next page for a diagram
showing typical mic input channel
logic connections.
!
Note only ONE microphone
channel may be programmed
for TB to STUDIO!
Mono mic input channel control connections are made at the channel's
UPPER12-pin LOGIC connector. Available control functions are as follows:
Pin 1 - TB TO STUDIO (jumper to pin 2 to activate)
Pin 2 - TB TO STUDIO
Typically one of the console's mic channels will be devoted to the control
room (console operator's) mic and the other to an additional studio. If the
mic channel you are wiring is for the control room mic, you would logically
want it to be able to talk back to the additional studio. By jumpering pins
1 and 2 together, a pre-fader, pre-on/off microphone signal for this input
channel will appear at the console's studio monitor output when the
console's TALKBACK button is pressed. (See TB, page 6-4).
Pin 3 - CR MUTE (jumper to pin 4 to activate)
Pin 4 - CR MUTE
If the microphone input channel you are wiring is for the control room
mic, you will probably want the console's control room monitor output to
mute whenever that mic is on-the-air to prevent announcer feedback. This
can be accomplished by jumpering Pins 3 and 4 together; whenever the
channel's ON button is pressed, control room speakers will mute.
If you have not done the
modification described on page
A-10, the studio level will DIM by
15dB instead of muting
completely.
If desired, the console's CUE
bus (and hence any TB-to-CR
signals) can also be programmed
to interrupt the control room
sreakers. See CUE-TO-CR,
page 6-6.
Pin 5 - STUDIO MUTE (jumper to pin 6 to activate)
Pin 6 - STUDIO MUTE
If the channel you are wiring is devoted to a studio mic, you can make the
console's studio monitor output mute whenever the channel is ON by
jumpering Pins 5 and 6 together.
Pin 7 - TB TO CR (control line; jumper to pin 10 to activate)
Again, if you are wiring a channel for a studio microphone you will want
that channel to be able to talk back to the control room (CR). By providing
a contact closure between Pins 7 and 10 (via a user-supplied momentary
"TB" switch located in the studio) the channel's pre-fader, pre-on/off signal
will appear on the console's CUE bus (and hence at the built-in cue speaker)
allowing the operator to hear it off-air. Note this same talkback signal will
also automatically interrupt the operator's headphone feed.
Pin 8 - REMOTE ON (momentary contact to pin 10 latches channel ON)
Used to turn a mic channel ON from another location (user-supplied
momentary contact switch required).
Pin 9 - REMOTE OFF (momentary contact to pin 10 latches channel OFF)
Used to turn a mic channel OFF from another location (user-supplied
momentary contact switch required).
Pin 10 - ON/OFF/TB COMMON
Used in conjunction with Pins 7, 8 and 9 for external control of channel.
The mic input ON TALLY may
also be used to drive an external
logic circuit. If the external circuit
will include additional lamps or
relays, these must be powered
from a separate supply. See
APPENDIX, page A-2, for a
recommended circuit.
R-5 / Jan 97

Pin 11 - TALLY COMMON (return from remote tally indicator)
Pin 12 - ON TALLY (lights remote tally indicator)
In addition to its own built-in switch "lamp" (in reality a solid state LED
indicator) the channel's ON switch can also run a second tally indicator
(maximum draw 25 milliamps) typically located in a user-supplied studio
talent control panel ON switch. This second indicator lets studio talent
know when their microphone is live.

STEREO LINE INPUTS
OVERVIEW
Each R-5 audio console is supplied with ten stereo line inputs; each
input can accept two stereo line signals which are accessed by an A/B input
selector switch at the top of the channel. Note there are two possible gain
settings provided for each A and B input: +4dBu (professional level
balanced inputs—the factory default) or an alternate –10dBu setting for low
level "consumer-type" equipment (the –10dBu setting is activated by wiring
jumpers in each channel's upper LOGIC connector; see top of page 3-5).
Each channel has its own CUE switch, allowing material to be previewed
prior to airplay; the CUE function is automatically deactivated when the
channel ON switch is pressed. At this point the channel signal is routed (at
the level set by the linear fader) to whichever console output busses have
been selected via the three ASSIGN switches (PGM, AUD and/or TEL)
Stereo line inputs also have built-in control circuitry that enables the
console operator to START and STOP external source machines by pressing
channel ON and OFF switches. Additionally, the channel's OFF switch
indicator LED can be controlled by a remote source machine, allowing it to
function as a flashing READY lite to show the operator when a machine is
cued up and ready to begin play. Finally, stereo line input channels may be
automatically turned off by the remote source machine (typically when it
has reached end-of-play). Detailed wiring information for these control
functions may be found on pages 3-5 and 3-6.

CONTROLS and FEATURES
GAIN SET - The stereo line inputs have two possible input gain settings:
+4dBu (for balanced, professional level equipment, usually equipped with
XLR output jacks), and –10dBu (for low level consumer-type equipment,
usually equipped with RCA plugs). The factory default setting is for +4dBu
levels; if you will be using low level equipment, it will be necessary to reprogram input gain at the channel's LOGIC (upper) I/O connector. See top
of page 3-5 for details.
A/B SOURCE - This switch (LED illuminated) selects between the two
electronically balanced stereo line level inputs. The "B" source is selected
when the switch is lit.
CUE – When pressed, this switch (LED illuminated), routes the channel
signal to the console's CUE bus, where it may be heard by the operator on
the meterbridge mounted internal cue speaker. CUE also automatically
interrupts the operator's headphones, and can be programmed to interrupt
the console's control room output as well, allowing it to be heard on the CR
monitor speakers.
ASSIGN - These switches (LED illuminated) determine where the input
signal will be sent; they route the channel signal to the console's stereo
Program (PGM), stereo Audition (AUD) and/or mono Telephone (TEL)
busses.
FADER - Stereo, long-throw carbon; plug-in for easy service.
ON/OFF SWITCHES - Turn the channel signal ON and OFF. Brightly
illuminated. If desired, they can perform several remote functions:
EXTERNAL CONTROL - Channel ON and OFF switches can START and
STOP an external source machine. The external machine can also
automatically shut OFF the channel when it reaches end-of-play, and can
flash the channel OFF switch indicator LED when it is READY and cued
up for play. All control ports are opto-isolated. Exact wiring details are
called out on pages 3-5 and 3-6.

The R-5 console normally accepts professional balanced (+4dBu level)
line level signals (maximum input +28dBu). However, the inputs may be
reprogrammed for –10dBu source levels if desired (see LOGIC connector,
next section). Generally speaking, –10dBu consumer-type equipment will
usually be found with RCA type output jacks; professional +4dBu level
equipment is more likely to use XLR jacks. Note the above ports connect
to high impedance, electronically balanced bridging-type input circuitry. If
you will be connecting unbalanced equipment to these input ports, be sure
to tie LOW and SHIELD together at the source end.
Page 3 - 4
STEREO LINE INPUTS
Stereo Line Input (Logic and Control Wiring)
As a rule of thumb, consumer
units (low level, –10dBu)
usually utilize RCA jacks and
two conductor wiring
connections; professional
level (+4dBu) equipment
generally uses threeconductor XLR connections.

Line input channel remote control connections (and optional –10dBu
gain settings) are made at the each channel's UPPER 12-pin LOGIC
connector. Pins are as follows:
Pin 1 - LEFT –10dBu GAIN SET (jumper to pin 2 to activate)
Pin 2 - [audio common]
Pin 3 - RIGHT –10dBu GAIN SET (jumper to pin 4 to activate)
Pin 4 - [audio common]
R-5 stereo line inputs normally accept professional +4dBu balanced
levels. However, they can be re-programmed for low level (–10dBu) consumertype source machines (usually unbalanced sources). If you will be using
this type of equipment, install the jumpers listed above. Also, when wiring
audio to the console from these machines, be sure to tie LOW and SHIELD
together at the source end of the connection. (See upper drawing on page
1-8.)
The remaining functions listed below (pins 5 through 12) will interface
with one playback machine (presumably the one connected to the channel's
"A" input). All control ports are opto-isolated.
Pin 5 - EXT START (w/pin 6 will start a remote playback machine)
Pin 6 - external START common
Pin 7 - EXT STOP (w/pin 8 will stop a remote playback machine)
Pin 8 - external STOP common
These pins are used to START and STOP a remote playback machine
whenever the channel's ON and OFF buttons are pressed. They should be
wired to the source machine's START and STOP connector pins. For
machine connector details see the owner's manual for the particular unit
you are using.
Pin 9 - REMOTE OFF
Pin 10 - remote OFF common
A momentary closure between pins 9 and 10 (usually provided by
professional playback machines at end-of-play) will turn the line input
channel OFF. For machine connector details see the owner's manual for the
particular unit you are using.
Pin 11 - READY
Pin 12 - READY common
These pins, when hooked to a source machine's READY TALLY port,
allow the channel OFF switch indicator LED to be flashed by the source
machine, letting it function as a READY indicator to tell the console
operator when that machine is cued up and ready to play. Functionally, the
source machine puts out momentary negative pulses to ground which
cause the R-5 logic circuits to interrupt current to the OFF switch LED,
making it flash instead of shine steadily. For machine connector details see
the owner's manual for the particular unit you are using.

TELEPHONE INPUT
OVERVIEW
This specialized input channel is designed to handle telephone call-in
talk segments. It makes use of the console's mono TEL bus to generate a
mix-minus feed to the caller; any inputs assigned to the TEL bus are fed to
the caller, whose voice signal is returned via the dedicated phone channel
fader and then routed (through ASSIGN switches) to either the PROGRAM
bus for live on-air broadcast or to the AUDITION bus for delayed tape
recording.
A CUE button allows interviewing the caller prior to airing. A separate
input (EXT, see flow diagram below) goes directly to the console TEL bus;
it may be used to introduce an additional feed to the caller.
The phone channel is used in conjunction with your station's telephone
hybrid, which interfaces between the console and the station's call-in
phone lines. The hybrid's output feeds the phone channel caller input. The
console's mono TEL output provides the signal going back to the caller;
this output feeds the hybrid's input.
A typical call-in segment might proceed as follows:
An alternate set-up might feed the
announcer mic signal (taken from that
mic channel's insert out point) into the
phone channel's external input, allowing
the caller to hear the announcer without
having to disturb the operator's mic
channel assign switch settings.
See also OUTPUTS chapter, page 5-2,
for additional information on phone
channel operation.
1) Caller phones in, announcer picks up off-air during a track play to
set up the call. He assigns his mic channel to TEL (first deactivating PGM/
AUD assignments so his voice doesn't go out over the air), hits his mic ON
switch, hits the phone channel CUE switch and talks to the caller, whose
voice comes up on the console's CUE speaker (and anywhere else CUE
has been programmed to interrupt—typically HDPN and/or CR). When he
is ready to take the call on-air, the operator
2) Deactivates CUE on the phone channel and assigns it to PGM,
3) Assigns his MIC channel to PGM (leaving TEL assigned) and does the
segment (caller voice level is controlled by the phone channel fader).
4) If the announcer wants to play any music during the segment, the
appropriate stereo line input is assigned to PGM and TEL, letting the
audience and the caller hear it.

CONTROLS and FEATURES
TEL TRIM - A recessed front panel trimpot at the top of the channel
adjusts the console's mono TEL output level.
ASSIGN - These switches (LED illuminated) determine where the call-in
segment signal will be sent; they route the channel signal to the console's
stereo Program (PGM) or stereo Audition (AUD) busses. Typically when
PGM is assigned the call segment will go out on-air; when the console's
AUDITION output has been wired to feed a recorder, the AUD button
permits off-air taping for later use.
FADER - Long-throw carbon; plug-in for easy service. Controls the level
of the caller's voice.
CALLER INPUT PORTS - There are two electronically balanced voice
input ports available: one is for –10dBu signals, the other for +4dBu levels.
They accept signal from your station's telephone hybrid.
EXTERNAL INPUT (internal) - Accepts a +4dBu balanced mono signal.
Feeds the console's TEL bus (see previous page).

Telephone Input (Audio Connections)
Telephone input channel audio connections are made at the channel's
LOWER 12-pin PHONE/TEL connector. These consist of electronically
balanced inputs for an external mono line level signal, the console's mono
TEL output, and two caller inputs (one for –10dBu signals and the other for
+4dBu levels).
Pin 1 - EXTERNAL INPUT, shield

There are two available: one for low level signals (–10dBu) and the other for
high level (+4dBu). The signals cannot come directly off a telephone
company line, but must first interface through your station's telephone
hybrid. This hybrid's output actually feeds the console's caller input ports.
If you will be using the –10dBu port and the source signal is unbalanced,
be sure to tie LOW and SHIELD together at the source end.

OUTPUTS
OVERVIEW
The make-up of R-5 output
signals is determined by which
input channels have been
assigned to which output busses.
For example, if input channels 2,
5 and 7 have their PGM assign
buttons activated, then their
combined signal will appear at
the console's Program output.
The R-5 console has three main outputs: PROGRAM (stereo),
AUDITION (stereo) and TELEPHONE (mono). All three are electronically
balanced and will drive +4dBu into 600Ω loads. Typically PROGRAM is
the master output and goes out over-the-air. AUDITION can be used to
feed a stereo tape machine for recording segments for later airplay.
These two stereo outputs are monitored by two pairs of VU meters (PGM
left/right and AUD left/right). Output levels for PGM and AUD are set by
concealed front panel trimports located just above the telephone input
channel underneath the console's hinged meterbridge. VU calibration
trimpots are located just above the Line Select switchbank at the
righthand end of the mainframe (beneath the hinged meterbridge). See
drawing on page 5-1.
The R-5's Telephone (TEL) bus is the console's mono output; its level
is adjusted by a trimpot located at the top of the phone channel. It does
not have an associated VU meter. The TEL bus also serves another
important function: it is used to generate a "mix-minus" feed for callers
during on-air telephone segments. In other words, the TEL bus ACN
(active combining network) signal is picked up by the phone input
channel and used to feed callers (thru the station telephone hybrid) a
special version of everything going out over the air—minus their own
voice. This prevents feedback during call-in segments.
Example: If the telephone segment is a "name that tune" contest,
the announcer's mic and the line input channel being used to play the
contest tune would both have PGM and TEL assign switches activated.
The telephone input channel would be assigned to PGM. The caller
hears a mono version of the tune plus the announcer over his
telephone line (which receives the console's TEL output thru the
station hybrid). Since PGM is also assigned, however, a full stereo
version of the same two signals plus the caller's voice (phone channel
PGM assign) is simultaneously going out over the air.
Output wiring connectors for all three busses (PGM, AUD and TEL)
are located at the top of the console, above the phone channel.
CONTROLS and FEATURES
R-5 console output circuitry is internal. The only applicable controls
are the front panel trimpots called out in the OVERVIEW section above.

MONITORS
OVERVIEW
CUE can also be programmed to
interrupt the console's stereo CR
output, allowing it's signal to
appear at the control room's
monitor speakers. See CUE-toCR, page 6-6.
The R-5 console has three stereo monitor circuits available to the
console operator that allow him (and other studio personnel) to hear
various console signal mixes without interfering with program content
going out over-the-air. They are:
1) CONTROL ROOM (CR) - a dedicated output designed to drive a
separate, user-provided power amp/speaker system in the main control
room;
2) STUDIO – a second stereo output intended for a remote (i.e., non CR)
studio power amp/speaker system;
3) HEADPHONE (HDPN) - an additional output (w/built-in power amp)
that drives the console operator's headphones. Its output appears at two
places: a headphone jack in the lower righthand corner of the console and
at a connector in the console's I/O wiring section.
What audio signal these three stereo monitor circuits carry is determined
by a SOURCE select switchbank which can choose from five signals: the
console's PGM, AUD, and TEL outputs, and two EXTernal line inputs,
which can be fed whatever end-user requirements dictate.
A fourth mono utility circuit, CUE, operates in conjunction with the
other three. This circuit appears at its own output connector for hook-up
to an external power amp/speaker system, and also includes an integral
power amp that drives the console's built-in meterbridge mounted cue
speaker. It is specifically designed to accomplish two important functions:
1) CUE can listen to any individual line input channel prior to it's going
on-air. It does this even when the channel is off, regardless of any fader
settings. The intended use here is for cueing up music tracks and program
segments prior to on-air play. CUE is activated by pressing any line input
channel cue switch, and when this is done its signal automatically
interrupts the console operator's headphone output and comes out of the
console's cue speaker. When the input channel's ON switch is pressed (for
on-air play), CUE is automatically deactivated.
The purpose of this function (called "cue drop-out") is to prevent a
potential on-air mishap: Assume a cue circuit system without this safety
feature has been used to ready an audio track for airplay and that line
channel now stands ready for firing (i.e., going on-air by pressing the
channel ON switch). The console operator, however, has forgotten to turn
the CUE switch off. He then turns on his announcer mic, does his set-up,
and segues into the next cut by hitting the line input ON switch. In
addition to feeding the console's PROGRAM output, cue audio from that
input will also be coming out of the console cue speaker, where it will be
picked up by his open microphone. The R-5's "cue dropout" feature
prevents this possibility.
2) The CUE bus also serves as a communication path for off-air links
between a) another studio and the control room, and b) telephone callers
and the console operator prior to over-the-air phone-in segments. In the
former case a studio microphone input channel can be placed into
TALKBACK-to-CR mode by a user-provided switch located in the other
R-5 / Jan 97

MONITORS
studio (see page 2-5), and that studio's microphone signal is then routed to the
CUE bus (regardless of the studio mic channel ON/OFF switch status and fader
setting) where the console operator can hear it on his headphones and the
console cue speaker (provided, of course, that his own microphone is not on-theair; if this is the case, then the cue speaker will be mute). For telephone work CUE
allows the console operator to listen to a telephone caller (via the console's CUE
speaker or his headphones) prior to putting him over the air (page 4-2).

CUE - The master level control for the CUE circuit. It controls the
built-in cue speaker; its output is also available at an I/O connector
and may be used to feed a separate, user-provided amplifier/speaker
system. The CUE output (mono) is electronically balanced and will
drive +4dBu into 600Ω loads. Note CUE is designed to automatically
interrupt the console's headphone output (and the CR output, when
so-programmed; see page 6-6). When it does so, the level of the
interruption is determined by the setting of this control. If the CUE
pot is set too high, you could end up with an unpleasantly loud
interrupt signal!
STUDIO - Controls the level of the console's studio output. The
output is electronically balanced, +4dBu into 600Ω. The studio output
signal is determined by the SOURCE select switchbank (see below).
TB (w/TRIM control) - When pressed, this momentary contact
switch (LED illuminated) routes the console operator's microphone
signal (pre on/off, pre-fader) to the studio output, where talent/guests
can hear it over a user-provided amplifier/speaker system. A recessed
trimpot sets the talkback level. Communication back from the studio
is accomplished by placing the studio microphone channel into
Talkback-to-CR mode ; the studio signal then appears on the console's
CUE bus where the operator can hear it. See page 2-5 for wiring details.
HDPN - Sets the level of the console's headphone output. This
appears at a front panel headphone jack (bottom of panel) and also at
an I/O connector. The headphone signal is determined by the SOURCE
select switchbank (below).
CR - The level control for the console's control room output. It
signal is determined by the SOURCE select switchbank (below).
Output is electronically balanced, +4dBu into 600Ω.
HDPN JACK - This stereo tip-ring-sleeve jack powers the console
operator's headphones. Medium impedance (nom. 60Ω) or higher
headsets are recommended.
SOURCE - This switchbank determines what signal the STUDIO, CR
and HDPN monitor circuits listen to. In addition to the three console
outputs (PGM, AUD and TEL), two external stereo line inputs are
provided. Typical uses for these include an off-the-air (tuner) signal,
recorder playback, AM or FM monitors for dual format facilities—in
short, any line level signal end-user requirements may dictate. Note
one of these external inputs can accept the output of the console's six
position LINE SELECT switchbank; greatly expanding monitor signal
capacity. See ACCESSORIES (Chapter 7) for details.
ON-AIR TALLY (internal) - The R-5 console provides a relay closure
(activated whenever CR output is muted) to control an external ON-AIR
tally light. See page 6-6 for details.

The R-5's headphone output is designed to drive medium impedance
(nominally 60Ω) or higher headsets through a built-in power amp. As the
headphone output signal that appears at this connector is paralled off the
built-in operator's headphone output jack, it may (depending on individual
operator preferences and headphone level control settings) be too hot for
an external amplifier that lacks input trim controls. Therefore, if you will
be using this port with an external power amp/speaker combination, you
may want to attenuate the signal, either with a supplementary pad circuit
or by using the external amplifier's input trim controls.

Tape Remote (Control Connections)
R-5 tape remote switches are simple closures brought out to I/O pins on
the two connectors dedicated to this accessory section. The top (upper)
connector is labeled TAPE I/O B and handles wiring for switches 4 thru 6
(PLAY, REC, STOP). The lower connector (TAPE I/O A) is dedicated to
switches 1 thru 3 (RTZ, FF, REW). Note each switch has an associated LED
indicator that may be powered by the remote machine if desired.

ACCESSORIES
Line Selector (Audio Connections)
The R-5 accessory line selector picks one of six external stereo line
inputs coming into the console (via three dedicated 12-pin connectors) and
sends it to the LINE output pins on the console's "LINE/HDPN OUT"
connector, where it may be picked up and wired to another console input
to expand its source capability (a stereo line input channel or one of the two
external line input ports on the console's monitor SOURCE select
switchbank are typical destinations).
Input connectors are located under the console's hinged meterbridge,
above the timer display. Output pins are on the upper connector directly to
the right of the inputs (LINE/HDPN OUT)
Each switch has a built-in LED indicator powered by the console.
Although the section contains active audio circuitry, it is functionally
equivalent to a "dry" switchbank, with no internal audio connections to the
console's other circuitry.

can also be used to feed an audio system external to the console. If that
system is unbalanced, we suggest tying LOW and SHIELD together at the
console end.

SET-UP
AND
TEST
FACTORY CALIBRATION
Your R-5 console has been pre-calibrated at the factory as follows:
1) Microphone input gain trimpots are adjusted so a –50dBu balanced
input signal yields a –2.5dBu output at the insert out patch point.
2) With the input channel fader set to max (all the way up) and the channel
assigned to PGM, AUD and TEL, output trimpots are then set to yield a
+16dBu output level.
3) The fader is then pulled down to its nominal setting (the two dots on
the scale) and the console's VU meter trimpots adjusted so the meters read
0dB (resulting in +4dBu console output levels.)
These are the standard factory settings.
END-USER SET-UP AND TEST
Assuming you have completed the basic steps called out in the first
chapter of this manual (i.e., mainframe is properly installed and grounded,
power supply is correctly rackmounted and connected to the console,
power-up has been verified) and the audio input, output and control
wiring for the console (as called out in subsequent manual chapters [mono
mic inputs, stereo line inputs, telephone input, outputs, monitors, and
accessories] is complete, you are now ready to verify proper set-up and
operation.
Before proceeding, power up the console, and check the following:
1) Make sure all channel ON/OFF switches are OFF.
2) De-activate all CUE switches.
3) Turn off all ASSIGN switching.
4) Run all FADERS down (off).
5) Turn all monitor pots (CUE, STUDIO, HDPN and CR) down to zero.
6) Set all INPUT A/B source select switches to "A" (unlit).
7) Plug in the console operator's headphone set.
Mono Mic Inputs
First, make sure of the following:
1) Has a microphone been connected to the mono input channel you will
be testing? Is the channel's A/B input select switch set correctly for the
microphone you will be using?
2) If you are using external equipment with the channel's insert patch
points, is that equipment turned on and operational? If you are NOT using
external equipment, is the patch point bridged at the channel's audio
connector? (If NO, then see bottom of page 2-4.)
Assuming the preceding conditions are correct, then
1) ASSIGN the channel to PGM.
2) Press the channel's red ON switch.
3) Move the FADER up to it's nominal setting (indicated by two dots).
4) At the console's monitor SOURCE select switchbank, press PGM.
R-5 / Jan 97
Page 8 - 2
SET-UP
AND
TEST
5) Speak normally into the microphone; the console's left and right
PROGRAM meters should respond appropriately.
6) Put on the headphones and slowly turn up the HDPN level control; you
should hear your own voice.
7) If your particular microphone does not yield a 0dB VU meter reading
when used under normal announcer conditions, first make sure any
external processing equipment being used at the channel's patch point has
its input and output gain settings properly adjusted. In other words, the
signal being returned to the console should be at the same level as the
signal leaving it (in the case of a factory calibrated console, this level will
be –2.5dBu). If it is not, make the necessary gain setting adjustment to the
external gear. If the settings are already correct, you may find it necessary,
depending on your particular microphone model and announcer mic
technique, to adjust the MIC GAIN TRIM control (at the top of the channel,
underneath the hinged meterbridge) until a 0dB reading is obtained with
normal voice input and a nominal ("two dot") fader setting.
8) If you have a microphone connected to the channel's "B" input, then
press the INPUT source select switch to activate that input (the switch will
light) and verify proper signal flow. (Note there is a separate mic input gain
trim for the "B" input.)
9) Turn off the first mic channel (press the amber OFF switch) and move
to the second mono mic input channel; repeat the same steps.
10) If the second mic input channel is used for a microphone in another
studio, and you have wired remote control functions from that studio to the
console channel, verify that these work properly. In other words, usersupplied ON and OFF switches in the remote studio should turn the
channel ON or OFF.
11) If the channel's remote ON TALLY port has been utilized, when the
channel is ON the remote indicator in the studio (either in the studio ON
switch itself, or as a separate ON-AIR light powered by a user-supplied
circuit [see page APPENDIX, page A-2]) should be illuminated.
Mono mic input studio and control room MUTE and TALKBACK
functions are discussed later in the MONITOR CONTROL SIGNALS
section (page 8-7) of this chapter.
Stereo Line Inputs
As you test your first stereo line input channel, you will also be verifying
the console's control room (CR), STUDIO and CUE circuits. We will
therefore assume you have installed:
a) a control room amplifier/monitor speaker system and that it is
being fed by the console's CR output;
b) a studio amplifier/monitor speaker system fed by the console's
STUDIO output; and
c) an external cue amp/speaker system fed by the console's mono
CUE output. Note this external CUE speaker system is optional, as the R5 console already contains its own built-in cue speaker/amp combination.

Page 8 - 3
SET-UP
See APPENDIX, page A-3, for a
discussion of appropriate gain
settings on user-supplied
external amplifier/speaker
monitor systems.
AND
TEST
We will also assume that these external amplifier/speaker systems are
energized and their gain settings are adjusted to an operational level.
1) Make sure a source machine is connected to the first stereo line input
channel (presumably the "A" source). Cue the machine up with program
material so it is ready to play. If the source machine has a low consumer
level output (–10dBu) make sure the console input connector has been
reprogrammed appropriately (see top of page 3-5). If the machine is a
professional unit with +4dBu output levels the console will accept this
signal with no further modification.
2) Run the fader up to its nominal setting.
3) Assign the channel to PGM.
4) Press the channel's red ON switch. If you have wired the source
machine to fire off of the console's ON switch, it should begin play
immediately. (If the source machine is not wired for control by the console,
then start it playing manually.) The console PROGRAM VU meters should
respond, and the source material should be audible over the operator's
headphone set.
NOTE: The external source machine can also be wired to feed a READY
tally signal to the console's OFF switch LED indicator. In this case, once
it is cued up and ready to play, the console's OFF switch should flash
intermittently instead of shining steadily. Note also the source machine,
once it reaches end-of-play, can also be wired to automatically turn the
console input channel OFF. If this is the case in your installation, verify
that these events occur as you test the channel.
!
See inset paragraph, page 6-2,
for the reasoning behind this
feature.
R-5 / Jan 97
5) Turn up the CR level pot. You should hear the input signal on the
control room monitor speakers.
6) Turn up the STUDIO level pot. You should hear the signal on the studio
monitor speakers.
7) Re-assign the input channel to AUD instead of PGM. All monitor audio
should stop, and the console AUDITION meters should now respond
instead of the PROGRAM meters.
8) Press the monitor SOURCE select switchbank AUD switch. Once
again, input audio should be heard over the CR and STUDIO monitors, as
well as the operator's headphones.
9) Re-assign the input channel to TEL. Select TEL on the monitor
SOURCE select switchbank. A mono version of the audio should be playing
through CR, STUDIO and HDPN.
10) De-activate the TEL monitor SOURCE select switch.
11) Press the channel CUE switch. Turn up the CUE level control. You
should hear audio on the console's built-in cue speaker and a mono version
of channel audio on the headphones. If you have installed an external cue
amplifier/speaker system, audio should be playing through it. If you have
programmed CUE to interrupt the console's CR output (see page 6-6), the
mono cue signal should appear over the CR monitor speakers. Note the
input channel fader setting does not affect the CUE interrupt level. Only
the rotary CUE level control pot does this.
12) Press the channel's ON switch again. Note the CUE signal drops out.
Whenever a channel ON button is pressed, that channel's CUE switch is
automatically de-activated. If you wish to override this feature, simply
press the CUE button another time—the cue signal will again be audible.
Page 8 - 4
SET-UP
AND
TEST
13) Press the input channel amber OFF switch. All audio should stop. If
the source machine has been wired for control by the console, it should
stop playing.
14) If you have a source machine connected to the channel's "B" input,
check that signal path as well, using the console's PGM ASSIGN and PGM
MONITOR signal path. (Note external source machine remote control
functions are not available for the B source; They function only with the
"A" input port.)
15) Check the remaining stereo line input channels.
Telephone Input
Prior to test, we will assume the following:
1) The console's mono TEL output has been connected to your station's
telephone hybrid input.
2) The station hybrid's output is feeding the R-5 phone channel CALLER
INPUT either at –10dBu or +4dBu, depending on output level (see page 4-4).
3) You will be talking to the caller via the console operator's microphone
input channel, using the console's TEL bus.
4) The console's PGM output is your on-air feed; the console's AUD
output is going to an external recording machine.
5) You will be playing a music track during the call using one of the
console's stereo line input channels.
6) The console operator's headphones are plugged in; the HDPN level pot
is turned up.
To test, perform the following steps:
1) Have an associate call the station using a regular contest line.
2) Assign your microphone channel to TEL, press the channel ON switch
and bring up the fader.
3) Activate the phone channel CUE switch and pick up on the call.
4) Hold your set-up conversation. You should hear the caller over the
console's cue speaker (provided the CUE level pot is turned up, of course)
and on your headphones. The caller will hear your voice from the station
hybrid (which is receiving the console's TEL output).
5) You are now ready to "go on the air". For this test we will send the callin segment to the console's AUD output, recording it for future airplay (it
could just as easily be going out over the air via the console's PGM output).
Select AUD on the monitor SOURCE select switchbank. If you have a
recording machine hooked-up to the console's AUD output, start it recording.
6) Deactivate the phone channel CUE button, press its AUD assign switch
and bring up the caller's fader.
7) Assign your mic channel to AUD (this is in addition to the earlier TEL
assign).
8) Do your phone-in segment, conversing with the caller. If you want to
play a track, assign the appropriate stereo line input channel to AUD and
TEL and do so.
R-5 / Jan 97
Page 8 - 5
SET-UP
AND
TEST
9) You should be able to hear the entire segment as it would be on-air
through the console operator headphones. NOTE you will not be able to
monitor it on the control room speakers, because they will have been
muted by the console operator's mic channel.
10) When the segment is over, de-activate TEL assign on your mic
channel and AUD assign on the phone channel. If you wish, play back the
recorded segment to verify that everything has worked properly.
NOTES: Depending on your particular set-up, you may wish to proceed
in a slightly different manner. For example, the caller could be receiving
your voice by a direct feed from your mic channel's insert out patch point
wired to the phone channel's EXT line input port. If this is the case, then
the console operator's mic signal will always be present on the console's
TEL bus, regardless of input ASSIGN switching, channel ON/OFF switches
and/or fader settings. This makes the segment easier operationally: To do
the set-up, pick up on the call and press the phone channel CUE switch.
Do your set-up using the operator's mic and the console cue speaker, and
when you're ready to go "on-air" turn off phone channel CUE, assign the
phone channel and your mic channel to PGM (or AUD if you're taping for
future airplay), and use their respective faders to control voice levels
(don't forget to press your mic channel's ON switch). If you will be feeding
music to the caller, be sure to assign that line input channel to TEL (so
the caller can hear it through the station hybrid) as well as PGM/AUD ("air/
tape") so the tune will also go out "over-the-air".
Outputs
Typically, the console's main stereo output (PROGRAM) will be the onair feed. AUDITION might then be wired to a stereo recording machine,
allowing program segments to be recorded for later airplay. The mono TEL
output is usually used to feed the station's telephone hybrid; it provides the
signal going back to incoming callers. These outputs are all electronically
balanced, with a +4dBu level into 600Ωs when the associated VU meters are
reading 0dB.
With a stereo line input playing and assigned to PGM, AUD and TEL,
verify that audio is indeed present at these respective console outputs.
Note again that if a console output is being used to feed consumer type
(–10dBu level equipment), the outgoing signal may be too hot for the
receiving unit. In this case, turn down the external machine's input gain
trims, or, if they are not available, you may wish to install a pad circuit
between the console output and the outboard unit (see page A-3 for a
suggested circuit). Be aware also of the proper way to hook up unbalanced
equipment to the console's balanced outputs (see page 1-8).
Monitors
Audio Signals
See "Stereo Line Inputs" section in this chapter for general testing of
monitor audio circuits. Note the monitor SOURCE select switchbank, in
addition to the console's three output busses (PGM, AUD, TEL), has two
R-5 / Jan 97
Page 8 - 6
SET-UP
AND
TEST
other selections: EXT 1 and EXT 2. These can be any line level signal you
wish to feed the console (including the output of the accessory line select
switchbank; see page 7-5). When selected, the audio you are feeding these
EXTERNAL monitor ports should appear on the console's CR, STUDIO and
HEADPHONE monitor outputs.
If you are using the console's I/O connector headphone output (instead
of or in addition to the console operator's front panel headphone output
jack) be sure you are familiar with the information set forth on page 6-5 of
this manual. Assuming you have set-up an external headphone system,
verify that its operation and level settings are as they should be. In other
words, the external headphone system should follow the monitor SOURCE
select switchbank, and should be interrupted by CUE whenever a CUE
switch is pressed anywhere on the console.
Control Signals
NOTE that while the console's
individual mic channel remote
TALLY functions (page 8-3) key
directly off input channel ON
switches, the console's ON-AIR
TALLY function is activated by
CR MUTE.
If you have not done the
modification described on page
A-10, the studio level will DIM by
15dB instead of muting
completely.
R-5 / Jan 97
99
You will already have verified the CUE interrupt feature of the R-5 console
during your test of the stereo line inputs.
The console's MUTE control lines should also be tested. Presumably you
will have assigned the console's first mono mic input channel to an
announcer mic located in the control room, and programmed that channel
to MUTE the console's CR output whenever that microphone is turned on.
To test this function:
1) Set up a stereo line input module to play a track; assign it's input
channel to PGM, assign the monitor SOURCE select switchbank to PGM,
turn ON the channel and then and turn up the CR level control. Assuming
the source machine connected to the line input is working properly, you
should hear audio at the control room speakers.
2) Now turn on the announcer mic channel. The control room speakers
should mute immediately, preventing feedback.
3) If you have wired up the console's ON-AIR TALLY function as well (page
6-6), the control room's ON-AIR indicator should also light up when the
MUTE function activates.
Assuming your second mic input channel is dedicated to a studio
microphone, and that studio has its own amplifier/speaker system fed by
the console's STUDIO output, AND the second mic input channel has been
programmed to MUTE STUDIO, then:
1) Set up a stereo line input module to play a track; assign it's input
channel to PGM, assign the monitor SOURCE select switchbank to PGM,
turn ON the channel and turn up the STUDIO level control. Assuming the
source machine connected to the line input is working properly, you
should hear audio at the studio speakers.
2) Now turn on the studio mic channel. The studio monitor speakers
should mute immediately, preventing feedback.
3) If you have wired up the channel's remote ON TALLY function as well
(page 2-5), the studio's ON TALLY indicator should light up when the
channel is turned ON.

SET-UP
AND
TEST
Talkback
There are two possible talkback paths with the R-5 console: CR to
STUDIO and STUDIO to CR.
In the first, CR to STUDIO, the announcer mic channel's pre-fader, preon/off signal is routed to the console's studio output whenever the
momentary action TB switch is pressed. Naturally, in order for this to work
the studio output must be operational; in other words, the STUDIO level
control must be turned up, and the studio microphone channel must be
OFF (if it were ON the studio speakers would be dimmed or muted). To test:
1) With the STUDIO level control set at its normal level (hopefully 6 or 7;
see page APPENDIX, page A-3) press and hold the console's TB button and
2) Speak into the console operator's (announcer) mic. Your voice should
come out over the studio monitor speakers. If the level is too loud or too
soft, adjust the front panel trimpot just above the TB button until it is the
way you want it.
In the second instance (STUDIO to CR TB), a microphone input channel
(presumably the console's second one) assigned to a studio microphone
has a remote momentary closure switch connected to that channel's TBto-CR control port. When the (user-supplied) talkback button in the studio
is pressed the studio microphone's pre-fader, pre-on/off signal is placed on
the console's CUE bus, where the console operator can hear it on the builtin cue speaker (or anywhere CUE interrupt is programmed to occur). The
level of the interrupt is determined by the CUE level pot; the studio mic
fader setting has no effect on the talkback level.
Accessories
Tape Remote Controls
Assuming you have wired up this switchbank per the console pinouts
called out on page 7-4 and in conjunction with the manufacturer's
information for your specific machine, verify each control function by
activating individual switches. Note, again, that each switch's LED indicator
must be powered by the external machine; there are no internal power
connections from the console.
Timer
When the console is initially powered up, the digital timer display will
energize immediately. After this first power-up, it may be necessary to hit
the RST (reset) button and/or S/S (start/stop) buttons in succession to zero
out the timer counter. Once this is done the timer will be fully functional
thereafter, with controls operating as follows:
S/S (START/STOP) – If the timer counter is stopped, pressing this button
once will cause it to start. If the counter is active, pressing this button once
will cause it to stop.
RST (RESET) – When pressed, resets the timer to zero. If the counter is
running, the display will immediately start to count up. If the counter is
stopped, the display will remain at 00:00.

Page 8 - 8
SET-UP
AND
TEST
HOLD – As long as this button is held down, the timer display will freeze
at whatever number it was at when the button was pushed. Note the HOLD
button does NOT stop the timer counter; when the HOLD button is
released, the timer display will immediately jump to the current count and
continue from there.
Line Selector
The accessory line selector switchbank should feed whichever signal is
activated to the switchbank output (and hence to any console or external
audio input this output has been wired to). Note individual switch LED
indicators are powered from the R-5 console itself and should illuminate
whenever a switch is turned on. Verify that designated audio signals are
going to the correct input destination.
This concludes set-up and test.

EXTERNAL ON TALLY CIRCUIT
R-5 input channel on tally circuits are designed to power 25 milliamps
at 5 volts DC (a typical solid state LED indicator). If you wish to run a larger
load with this control port, it will be necessary to provide an external relay
with its own power supply. The drawing below shows a suggested circuit for
accomplishing this:
relay circuit powered by user
supplied power supply
!
Don't forget the snubber diode
(1N4002). It must be used to prevent back EMF from the relay from
damaging the 2N3903 transistor
shown, as well as the driver circuitry
in the R-5 console.

EXTERNAL HEADPHONE PAD CIRCUIT
The R-5's external headphone output parallels the console's headphone
jack, which is driven by an internal power amp. If you will be using the builtin jack AND driving an external amplifier from the I/O connector port (see
page 6-5 for details), you may find (depending largely on the console
operator's preferred HDPN level pot setting) that the feed to the external
headphone power amplifier is too hot for the amp's input circuitry. If the
external amp lacks input gain trims to remedy this, we suggest the
following pad circuit be installed at the amp:

APPENDIX
MONITOR LEVEL SETTINGS
It is a characteristic of most all rotary potentiometers that they perform
best in the mid and upper portions of their audio control range. This is just
common sense: if the gain structure of your external monitor/speaker
system is set way up so a console level pot setting of only 2 or 3 results in
a very loud signal at the speaker, then a very small movement of the control
will result in a major level change. If, on the other hand, the external amp/
speaker system has its input gain turned down, then the console level
control can have a 6 or 7 setting, resulting in a much a wider control range
(i.e., a small movement of the pot results in a correspondingly small change
in level).
There are other advantages as well: left-right tracking is more consistent
throughout a control's mid and upper range than at the bottom of it's taper;
when a control pot is choked back to "almost off" the signal is radically
attenuated; if the external amplifier is then turned way up to produce a
satisfactory speaker level, any distortion or left/right mismatches introduced
by the control pot will be amplified as well. Bottom line? Set your external
amplifier input gain controls/trims so a console rotary control setting of 6
or 7 results in a satisfactory studio/control room speaker level. This will
give you the best of both worlds.
If your external amplifier doesn't have input gain controls, you may wish
to introduce an external pad (attenuation) circuit at the amplifier end of the
feed. The circuit shown in the drawing below will work with any of the
console's electronically balanced outputs (i.e., any output except mono
mic channel insert patch points and the console's HDPN circuit [see
preceding section]). It will provide approximately 17dB of attentuation.

DISABLING PHANTOM POWER
Mono mic input channels have built-in phantom power (+18VDC) that
is always on. This will cause no problems for the majority of available
microphones; however, should you find it necessary to disable phantom
power, this can be accomplished by removing two 4.99KΩ (1% precision)
resistors from each associated microphone input channel. The four
respective resistor pairs are shown below.
Rear view of MB-5 motherboard, behind microphone channel I/O audio
connectors, showing location of phantom power resistors (four pairs:
aR10/11, aR14/15, bR10/11, bR14/15).

HAND CRIMP TOOL WIRING INSTRUCTIONS
The supplied hand crimping tool (PALADIN model PA1645, W/S#850067) is
used for all I/O wiring connections to and from the console. It is to be used with
the supplied .062" pin diameter silver crimp terminals (figure 1) intended for 22
gauge wire.

TABS
(2) The terminal conductor tabs (pointing UP) are placed in anvil
18-22; the terminal's insulation tabs extend in front towards the
camera.

(3) The stripped 22 gauge wire is placed into the terminal and

conductor tabs (detail)
CONDUCTOR TABS
(1) .062" pin diameter silver crimp terminal
1) Strip wire approximately 3/16" (insert in
proper wire stripper, rotate one half turn, and
pull insulation off wire).
2) Leaving wire aside for the moment, with
Paladin tool fully open (engraved side toward
you) bring a terminal into position from the
unmarked side of the tool. Place the conductor
tabs (inner set as shown in figure 1) on the "1822" or "24-30" (depending on the wire) anvil
(slightly curved surface) so that the circular
portion of the tabs rests in the curved surface of
the anvil and the two tabs face up into the walls
of the female jaw. The insulation tabs will be
flush with the top of the tool (figure 2).
3) Close tool very slightly, only to the point of
holding the terminal in position (figure 2).
4) Insert wire into terminal until wire
insulation is stopped by conductor tabs (figure
3). CRIMP by squeezing handles until jaws are
fully closed.
5) If there is an insertion error or if a circuit
change is needed, you'll need to use an extractor
tool to remove terminals (next section).
(4) Final step: jaws fully closed; the insulation tabs have been
crimped.

EXTRACTOR PIN INSTRUCTIONS
If you should accidentally insert a crimp terminal pin into the wrong socket,
the supplied pin extractor tool (Waldom P/N W-HT-2023) will let you correct your
mistake without having to sacrifice a connector.
STEP 1.
Push wire attached to pin terminal, to
be removed, forward to free pin
terminal locking flanges from the
Nylon Connector Housing.
STEP 2.
Place extractor tip over pin
terminal to be removed. Press
handle portion of extractor in
downward motion until tip rests
upon Nylon Housing.
STEP 3.
Push ball at top of extractor
down toward pin terminal; pin
terminal will extract from Nylon
Housing.

APPENDIX
INSERT POINT BRIDGING RESISTORS
R-5 console mono mic input channels have built-in insert patch points.
These patch points are bridged at the factory with a 10Ω resistor so signal
will pass through the input channel without any external gear installed.
If you will not be using the insert points, or will only be utilizing the
INSERT OUT port (for use as a direct output from the input channel) there
is no need to modify anything. If, however, you plan to use the insert point
as a pair of I/O ports for an outboard processing loop, with the signal
leaving the console from INSERT OUT and returning after processing to
INSERT IN, it will be necessary to remove the insert bridging resistor for
that channel.
There are two bridging resistors; both are 10Ω, with one for mic input
channel 1 (resistor "aR9") and one for mic input channel 2 (resistor
"bR9"). These are shown on the schematic drawings at coordinates D-7
(pages 9-2 and 9-3) and on the MB-5 Motherboard PCB pictorial (page 9-12)
in the upper righthand corner of the page. The photo below shows a closeup of the pertinent section of the board. Note once the resistor(s) are
removed, each position has two thru-hole pads for jumper replacement
should you decide to go back to the original factory configuration.
Rear view of MB-5 Motherboard PCB (detail). The mono mic input insert
point bridging resistors shown must be removed if you plan to use external
processing loops in the signal chain.

STUDIO DIMMING RESISTORS
The R-5 STUDIO MUTE circuit is factory set as a 15dB dimming circuit
instead of a muting circuit by the presence of two resistors, R260 and
R261, with a value of 22.1KΩ each. These are shown on the schematic
drawing at coordinates C-3 (p.9-18) and on the OM-5 Output Board
pictorial (p.9-21) at the left edge of the page. To change the circuit to
perform muting instead of dimming, remove R260 for the right Studio
Out and R261 for the left Studio Out. The photo below shows a closeup
of the pertinent section of the board.
Rear view of OM-5 Output Board PCB (detail). The dimming resistors shown must
be removed if you need full muting capability in the Studio Output.
