Yamaha DSR-100PRO Owner's manual

 Congratulations
‘You are now the proud owner of a Yamaha DSR-100PRO
Dolby Pro Logic Surround Processor. This sophisticated digital
surround decoder lets you experience the full realism and impact
of Dolby Surround movie theater sound in your own home.
Dolby Pro Logic Surround gets its name from its professional-
grade directional logic circuitry, which provides greater effective:
— channel separation for a much higher degree of realism than
the “passive” Dolby Surround circuits found in today’s typical —
home audio/video equipment. With a suitable complement of
surround amplifiers and speakers, the DSR-100PRO can bring
you the kind of exciting, dramatic listening experience that nor-
mally can only be had at leading movie theaters.
To further extend the range of realistic listening environments
you can create with your system, we recommend the Yamaha
— DSP-series Digital Sound Field Processors. These DSP units
simulate some of the world's most famous music listening en-
vironments, including actual movie theaters, concert halls, cathe-
drals, and jazz clubs. They are also effective with any audio
source, including monophonic program material. Together, the -
DSR-100PRO and a DSP unit such as the DSP-1 or DSP- 3000
form a perfect pair, for the ultimate in listening excitement.
To assure maximum performance and trouble-free operation, ‘
refer to the connection recommendations and operating instruc-
tions in this manual. Be sure to store the manual 1 ina safe place
a for future reference. 1

Putting in the Batteries
Since the remote is handy for controlling DSR-100PRO
operations, begin by installing the supplied batteries.
1. The battery compartment cover is on the back of the re-
mote control unit. To open, pull down on the compartment
cover clip while pulling the cover outward.
2. Insert the two batteries (SUM-3 or AA type), being
careful to align their polarity with the markings inside the
compartment.
3. Put the battery compartment cover back on.
* The batteries should last for quite a while, but they
should be replaced if remote control operation seems
erratic or If it no longer works from a reasonable distance.
Always replace with two new batteries. Any SUM-3 or
AA type batteries will do, but they should both be the same.

direct line from the remote to the DSR-100PRO is obstruct-
ed by furniture or other items, or if you press the keys while
aiming the remote away from the DSR-100PRO.
Amplification and Speaker Arrangements
The Basic System
To achieve the same dynamic sound that the professional
Dolby systems in movie theaters do, the DSR-100PRO “active
circuit configuration breaks the Dolby Surround encoded
stereo signal into several different channels: a center
channel for dialog, the main left and right channels, and
rear surround channels. A typical system setup includes
five speakers with appropriate amplifiers. The center dialog
speaker is placed adjacent to the screen, the main speakers
are placed in their usual positions for stereo listening, and
the surround speakers are placed at the left and right
sides in the rear. a
If for some reason it is not practical to use five speakers,
It IS possible to eliminate the center dialog speaker. The
“phantom” mode is used in this case to route the dialog to
the main speakers. Best results are obtained with the full
five-speaker system, however.
It is also possible to further expand your system with the
addition of a subwoofer and amplifier. The subwoofer
should be placed in the rear of the room in the center.
NOTE: The Yamaha M-35 power amplifier (which provides
four channels of amplification) is recommended to satisfy
your additional amplification system needs.
Dolby Pro Logic Surround Technical Notes
The DSR-100PRO uses an “active” circuit configuration
which is similar to professional Dolby stereo decoders em-
ployed in movie theaters. How is this different from the
“passive” decoders found in typical home equipment?
The Dolby Pro Logic Surround system is distinguished
by logic circuitry that emphasizes “directional” information
by proportionally canceling unwanted crosstalk. Taking the
left and right channel signals as its input, the DSR-100PRO
first- produces two additional signals, a left-plus-right signal
(L+R) for the center channel and a left-minus-right signal
(L-R) for the rear surround channel. It then compares the
levels of these four signals, L, R, L+R, and L-R. Based on
these level differences, the DSR-100PRO emphasizes par-
ticular channels. For example, dialog is characterized by
an increase in L+R signal level. When this is detected, the
DSR-100PRO routes dialog to the center channel. As this
results in a slight drop in the signal level sent to the left and
right speakers, the DSR-100PRO boosts the center channel
slightly to maintain overall volume at a constant level. Simi-
larly, when L-R signal level is high, the DSR-100PRO boosts
the surround channel level and reduces left and right chan-
nel levels.
This results in the high dynamic range and sharp effec-
tive channel separation of 26—40dB. Dolby Pro Logic Sur-
round provides a true center channel, so that there are four
independent channels, unlike passive Dolby Surround
which in effect has only three channels, left right and rear.
In fact, in a passive Dolby Surround system, it is a bad
idea to use a center speaker, because it would reduce the
effective channel separation that you hear between the left
and right speakers. However, with the DSR-100PRO's ac-
tive circuitry, dialog is automatically locked on screen while
maintaining the width and separation of the stereo sound
stage.

Equipped with Center Switch to Match Your System
On the rear panel of the DSR-100PRO you will find a
CENTER MODE switch. This has an important role in
matching DSR-100PRO operation to the capabilities of
- your audio system.
e When this switch is at the ON position, a center channel
- signal is provided to the center output jack. Information
below 100Hz is fed to the left and right main speakers, so
you can use a relatively small speaker system for center
channel reproduction.
e |f not using a center speaker, you should set this switch
to the PHANTOM position. This allocates all center channel
information to the left and right main speakers.
With a Yamaha DSP-Series Sound Field Processor
The DSR-100PRO is equipped with a complete set of
inputs and selection facilities for connection to Yamaha
DSP-Series Digital Sound Field Processors. In this case the
pair of rear speakers used in the basic DSR-100PRO sys-
tem also handles the DSP-Series rear effect signals. DSP-
Series front effect channels can be reproduced indepen-
dently of the main front speakers (in which case you will
need yet another stereo amp and speakers). Or they may
be blended with the conventional main speaker output (by
setting the DSR-100PRO FRONT MIX switch to the ON po-
sition and setting the DSP-Series unit's FRONT MIX switch
to the Gch or OFF position). At a later date you can always
upgrade to a full 6-channel setup.
In either case, the DSR-100PRO's volume control alone
can adjust entire system volume, a real convenience, par-
ticularly with the remote.
DSP: In the following explanations, special notes con-
cerning DSP-Series connections and operations will be
preceded by the “DSP” mark.
Receivers and Integrated Amps versus Separate Pre-
and Power Amps
If your current hi-fi system is built around a receiver or
integrated amp then you can continue to use it for source
- Selection and to drive your main (front) speakers.
However, you may notice that sound quality is better
with a separate preamp and power amp.
For the center channel, you may wish to purchase a
mono power amp. For the rear surround speakers and (if
using a DSP-Series unit) front effect speakers, additional
stereo power amps are the optimum solution. However, if
you already own an extra receiver or integrated amp then
it can be used just as well.
For subwoofer output you may wish to choose the con-
venience and sound quality of a Yamaha Electronic Super
Woofer System which has its own built-in power amp.
Otherwise, you will need another mono amp and a single
subwoofer speaker system.
Before You Start Making Connections Make Sure that the DSR-100PRO and All Related Electronic Components are
Turned Off.

Speakers & Speaker Placement
In a full 5-channel system you will use two sets of stereo
speakers: the front MAIN SPEAKERS (your normal stereo
speakers), the rear SURROUND SPEAKERS, and the CEN-
TER SPEAKER. You may also be using a SUBWOOFER.
© |
(
Surround Speaker . /
You Will probably use your present stereo speaker sys-
tem for the MAIN SPEAKER pair. The rear and center
speakers do not need to be of such high quality. But they
should have high enough power handling to accept the
maximum output of the amps that will drive them. The rear
channel output is filtered so that it covers only the frequen-
cles between 100Hz and 7kHz. Therefore, you do not need
to worry about reproduction of the high treble and low
bass tones—they are not present in the surround channel
signal. —
Place the MAIN SPEAKERS in their normal position.
Place the rear SURROUND SPEAKERS beside your
listening position and facing inward. They should be nearly
six feet up from the floor. If your power amp can drive two
sets of speakers, all the better. Place the second pair be-
hind you for even greater effectiveness.
Place the CENTER SPEAKER precisely between the
two MAIN SPEAKERS, (To avoid interference, keep the
speaker away from TV sets, or use a magnetically shielded
speaker) ‘
If using a SUBWOOFER such as a Yamaha Electronic
Super Woofer System, the position of the speaker is not so
critical because low bass tones are not highly directional.
DSP: If using additional FRONT EFFECT SPEAKERS, in-
stall them further apart than the MAIN SPEAKERS. It is
best to move the MAIN SPEAKERS slightly inward and
mount the FRONT EFFECT SPEAKERS on the wall several
feet above and behind them.
The Dolby Surround rear SURROUND SPEAKERS
double as the REAR EFFECT SPEAKERS in the DSP sys-
tem. Adjust their position so that they are at about the
same height and distance apart as the DSP FRONT EF
FECT SPEAKERS. Ideally, the four effect speakers should
be mounted in the corners of the room, all pointing down-
ward and inward toward the listening position.
DSP: If not using additional FRONT EFFECT SPEAKERS
(that is, if the FRONT MIX switch on the DSR-100PRO is
on), then the MAIN SPEAKER pair will also be reproduc-
ing the DSP front effect signals.
Set the MAIN SPEAKERS in the position that gives the
best stereo image. They should be reasonably wide apart
and at equal distances from your listening position.
NOTE: Since most speakers are sold in pairs, one practical
solution is to use one speaker for the center channel and
the other for the surround channel.
In this case you would use only one of the rear speaker
output jacks, either L or R. This is possible because in the
Dolby Surround system the surround channel information is
actually monophonic.
However, this is not recommended if you are using the
DSR-100PRO with a Yamaha DSP series unit.
Room Furnishings
You will get maximum realism from the DSR-100PRO
and DSP-Series units if the listening room is carpeted and
curtained so that it absorbs sound waves. With this kind of
acoustically “dead” room, most of what you hear comes
from the speakers and not from room reflections. However,
these are recommendations for optimization. You will find
the DSR-100PRO to be effective in virtually any listening
area.
General Instructions for Connections
Use the supplied stereo cables or an equivalent high
quality connection cable.
Make sure that you have the left (L) and right (R) chan-
nels correctly connected. That means that the jack marked
“L” on the amp must be connected to the jack marked “L
on the DSR-100PRO. Likewise with the “R” jacks. This Is
easy if you remember to always use the red plugs for the
“R” jacks and use the other plugs for the “1” jacks. By
convention, “R” jacks are located below “L” Jacks.
With speaker connections you must also be sure that
the polarity is correct. For each amplifier and each chan-
nel, connect the plus (+) terminal of the amplifier to the
plus terminal of the speaker, and connect the minus (—)
terminal of the amplifier to the minus terminal of the speak-
er. To keep track of polarity, use speaker cable that has one
of the two wires marked by a stripe or a different color

CONNECTING THE SURROUND POWER AMPLIFIER
AND SPEAKERS
Connect the DSR-100PRO's REAR OUTPUT jacks to
the input jacks of the power amplifier that will drive the rear
SURROUND SPEAKERS.
Connect the speakers to the amplifier.
NOTE: A 4-channel power amp such as the Yamaha M-35
can be used to drive both the MAIN SPEAKERS and the
rear SURROUND SPEAKERS. With this kind of amp you
would use the first two channels of the power amplifier
(channels “1” and “2” or “A” and “B”) for the MAIN
SPEAKERS, and the second two channels (37 and 4
or “C” and “D”) for the rear SURROUND SPEAKERS.
CAUTION: It is absolutely essential that all connections are
matched according to channel, that is, left-to-left and right-
to-right. In the case of the speaker terminals, you must also
be careful to match the polarity of the terminals as well.
CONNECTING A CENTER AMPLIFIER AND SPEAKER
AND/OR SUBWOOFER SYSTEM
True center channel capability is one of the most impor-
tant features of the Dolby Pro Logic Surround system.
On the rear panel of the DSR-100PRO are two jacks in
the section marked “CENTER” The upper CENTER jack is
for the Dolby Pro Logic Surround center channel output.
Connect this to the input jack on the center channel power
amp. In turn, connect the CENTER SPEAKER to the
speaker terminals on the amplifier
Do the same for the DSR-100PRO subwoofer output
jack (the lower jack marked “low pass fe=200Hz ) if you
Will be using this option. A Yamaha Electronic Super Woof-
er System is highly suited to this purpose since it combines
a mono power amp and subwoofer speaker in a single
cabinet.
NOTE: The signals from these jacks are monophonic so
separate mono amps are recommended to provide inde-
pendent amplification. The use of a stereo power amp to
handle both of these mono signals is another alternative.

2-1. INPUT LEVEL ADJUSTMENT
The DSR-100PRO is designed to accept input signal levels
of up to 3 volts. Distortion occurs if input signal level ex-
ceeds this value. On the other hand, noise increases if in-
put level is insufficient.
NOTE: Input level adjustment is not possible or necessary
if the DSR-100PRO is connected directly to a VCR, video
disc player, or to the tape jacks of an | Integrated amplifier or
receiver.
1. Listen to a Dolby Surround encoded source and turn on
the Dolby Surround Mode switch on the DSR-100PRO
front panel.
2. Adjust the preamplifier, integrated amplifier or receiver
volume control to the point where both noise and distortion
“are minimized.
Raise the volume slightly if you hear excessive noise
from the effects speakers.
Lower the volume slightly if your hear distortion from the
effects speakers. It is particularly important to check for dis-
tortion on the highest level music peaks, since these have
the greatest chance of overloading the circuitry.
3. When you are satisfied with the sound quality, make a
note of the volume setting.
NOTE: You will want to return to this volume setting for
optimum sound quality when using the DSR-100PRO.
Final volume adjustment should be performed on the
DSR-100PRO (and on the power amps driving the various

BACK WITH DOLBY SURROUND
1. Turn on the power on all components in the system.
2. Turn on the Dolby Pro Logic Surround Mode switch.
3. Select your input source on the preamplifier, integrated
amplifier, or receiver.
* |f the source is a tape deck connected tothe
DSR-100PRO rear panel tape jacks, then set the front
panel tape monitor switch to the ON position.
4. Adjust the master volume control knob on the
DSR-100PRO front panel.
5. If necessary, use the remote control unit to change the
delay time setting.
6. If necessary, adjust the front panel center and rear level
controls to match your listening source.
NOTE: The Dolby Pro Logic Surround system is designed
to be used with program material (mainly videotaped
movie soundtracks) that is encoded with the Dolby Sur-
round system. The results with material not encoded with
Dolby Surround may be unnatural.
NOTE: Some amplifiers and receivers have built-in sur-
round sound or ambience processing circuitry. If this is the
case in your system, then be sure that the surround or am-
bience circuitry is off on the source amp or receiver while
you are using the DSR-100PRO’s Dolby Pro Logic Surround
decoding function.
3-2. ORDINARY STEREO REPRODUCTION
Set the Dolby Pro Logic Surround Mode switch to the
OFF position. Then operate your system components
as usual.
* Be sure to turn on the power on the DSR-100PRO
e |f the source is a tape deck connected to the
~ DSR-100PRO rear panel tape jacks, then set the front
panel tape monitor switch to the ON position.
3-3. SOURCE SELECTION WITH TAPE
OOP CONNECTION
If your integrated amp or receiver tape jacks are used
for connection to the DSR-100PRO, then the amp or
receiver looks at the DSR-100PRO as if it were a tape
deck. Therefore, you must set the amp or receiver as if
you were going to make a tape recording of your desired
listening source.
If the amp or receiver has a REC SELECTOR, set it to
your desired listening source.
If it does not have a REC SELECTOR, simply select
your listening source using the usual controls.
Turn on the TAPE MONITOR switch on the amp or
receiver.
NOTE: If the DSR-100PRO is connected to the tape jacks
on an integrated amp or receiver, then all of the tape relat-
ed controls (tape monitor switch, tape deck selector, rec
out selector, and tape dubbing selector controls) may affect
operation. It is therefore necessary to pay special attention
to the settings of these controls in order to assure the cor-
rect routes for the signals.
"TO THE DSR-100PRO |
You can make tape recordings at any time, regardless
of switch and control knob settings on the DSR-100PRO.
The DSR-100PRO's rear panel TAPE REC OUT jacks pro-
vide the same signal as is input to its MAIN INPUT jacks.
However, the recorded signal does not include the effect
of the Dolby Pro Logic Surround decoder

Using DSP Series Sound Field Programs
Note that it is possible to use the Dolby Pro Logic Sur-
round decoding feature of the DSR-100PRO together with
sound field programs on the DSP Series Sound Field
Processors. A certain amount of experimentation will be
required to determine suitable sound field programs for a
given movie scene. Don't use the Dolby Surround preset
program on the sound field processor when you are using
the DSR-100PRO.
Example DSP Presets for use with Dolby Pro o Logic
Surround Decoding
Music video | Club, or Concert | Ш
Adventure/Mystery Theater, Chamber, Pavilion
Musical Concert Hall
Drama Presence, Chamber, Theater
Do not use the Dolby Surround preset on the DSP unit.
— 4-1. GENERAL SETTINGS AND
RECOMMENDATIONS
The DSP unit should be connected between the source
unit (preamp, integrated amp, or receiver) and the
DSR-100PRO.
Set the DSP units MAIN LEVEL switch to 0dB in all
cases. This is essential to assure high sound quality from
the DSR-100PRO.
set the DSP units FRONT MIX switch to “OFF” or “6ch”
in all cases, regardless of how many effects channels you
will be using. a
If you are using an integrated amp or receiver and it is
: equipped with PRE OUT and MAIN IN jacks, then it is
highly recommended that you use them instead of the
TAPE PB and REC jacks.
NOTE: Be sure that the DSP unit's FRONT MIX switch is
OFF. If the DSP unit's FRONT MIX switch is set to “ON” or
“4ch, then the main output going to the DSR-100PRO
main input will contain DSP front effect information. This will
interfere with Dolby Pro Logic Surround decoding.

Speaker System Configuration for DSP Units
__ For optimum results when you use a DSP unit with the
DSR-100PRO, you may wish to add one more pair of
speakers to reproduce the DSP front effect output. This
gives you a total of seven individual speakers.
However, without these extra speakers you can con-
figure a 5-speaker system by setting the DSR- 100PRO’s
FRONT MIX switch to the ON position.
For a simple 4-speaker system without a center speaker,
additionally set the DSR-100PROss rear panel CENTER
MODE switch to the PHANTOM position.
* The DSR-100PRO's surround speakers also handle the
DSP units rear effect signals.
* [he DSR-100PRO'S. center channel output does not
reproduce DSP signals.

reproduce | DSP signals.
Speaker Placement for DSP Units
Place DSP front effect speakers above and behind the
main speakers, facing inward toward your listening position.
Place the rear speakers on both sides of your listening
position or behind your listening position. Experiment to
decide which position gives the best results in your listen-
ng room.
