PROFILE OF THIS UNIT
You are the proud owner of this Yamaha stereo receiver –an extremely sophisticated audio component. The Digital Sound Field
Processor (DSP) built into this unit takes full advantage of Yamaha’s undisputed leadership in the field of digital audio processing to
bring you a whole new world of listening experiences. Follow the instructions in this manual carefully when setting up your system,
and this unit will sonically transform your room into a wide range of listening environments –movie theater, concert hall, and so on.
In addition, you get incredible realism from Dolby-encoded video sources using the built-in Dolby Pro Logic Surround Decoder.
Rather than tell you about the wonders of digital sound field processing, however, let’s get right down to the business of setting up
the system and trying out its many capabilities. Please read this operation manual carefully and store it in a safe place for later
reference.
Digital Sound Field Processing
What is it that makes live music so good? Today’s advanced
sound reproduction technology lets you get extremely close to
the sound of a live performance, but chances are you’ll still
notice something missing: the acoustic environment of the live
concert hall. Extensive research into the exact nature of the
sonic reflections that create the ambience of a large hall has
made it possible for Yamaha engineers to bring you this same
sound in your own listening room, so you’ll feel all the sound of
a live concert.
What’s more, our technicians, armed with sophisticated
measuring equipment, have even made it possible to capture
the acoustics of a variety of venues such as an actual concert
hall, theater, etc. to allow you to accurately recreate one of
several actual live performance environments, all in your own
home.
Dolby Pro Logic Surround
The Dolby Pro Logic Surround Decoder program lets you
experience the dramatic realism and impact of Dolby Surround
movie theater sound in your own home. Dolby Pro Logic gets
its name from its professional-grade steering 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.
Dolby Pro Logic Surround provides a true center channel, so
that there are four independent channels, unlike passive Dolby
Surround which has in effect only three channels: left, right,
and rear. This center channel allows listeners seated in even
less-than-ideal positions to hear the dialog originating from
action on the screen while getting a stereo effect as well.
This Dolby Pro Logic Surround Decoder employs a digital
signal processing system. This system increases sound
stability at each channel and minimizes crosstalk between
channels compared to conventional analog Dolby signal
processing.
In addition, this unit features a built-in automatic input balance
control. This circuit always presents you the best surround
conditions without performing manual adjustments.
“ENHANCED” Dolby Pro Logic Surround
This unit has a second mode of Dolby Pro Logic Surround
processing called “Enhanced Dolby Pro Logic Surround”
processing. Enhanced Dolby Pro Logic Surround processing
recreates the surround effect of a movie theater, effectively
duplicating its multiple surround loudspeaker system,
completely surrounding the listener with the sounds of the
action taking place on the screen.

SPEAKER SETUP FOR THIS UNIT
SPEAKERS TO BE USED
This unit is designed to provide the best sound-field quality with a 5 speaker configuration. The speakers to be used with this unit
will be mainly front speakers, rear speakers, and a center speaker. (You can omit the center speaker. Refer to the “4-Speaker
Configuration” shown below.)
The front speakers are used for the output of the main source sound and the effect sound. They will probably be the speakers of
your present stereo speaker system. The rear speakers are used for the output of the effect sound. And the center speaker is
used for the output of the center sound (dialog etc.) encoded with the Dolby Surround. The rear and center speakers do not need
to be equal in power to the front speakers. However, all the speakers should have high enough power handling to accept the
maximum output of this unit.
SPEAKER CONFIGURATION
5-Speaker Configuration
This configuration is the most effective and is the one that is
recommended. In this configuration, the center speaker is
necessary as well as the rear speakers. If the digital sound
field program is in DOLBY PRO LOGIC or ENHANCED mode
conversations will be output from the center speaker and the
ambience will be excellent.
●
Set the center mode to the “NORMAL” or “WIDE” position.
(For details, refer to page 11.)
4-Speaker Configuration
The center speaker is not used in this configuration. If the
digital sound field program is in the DOLBY PRO LOGIC or
ENHANCED mode, the center sound is output from the left and
the right front speakers. However, the sound effect of other
programs can be the same as that of the 5-speaker
configuration.
●
Be sure to set the center mode to the “PHANTOM” position.
(For details, refer to page 11.)
SPEAKER PLACEMENT
The recommanded speaker configuration, the 5-speaker configuration, will require two speaker pairs: front speakers (your normal
stereo speakers), and rear speakers, plus a center speaker. When you place these speakers, refer to the following.
Front: In normal position. (The position of your present
stereo speaker system.)
Rear: Behind your listening position, facing slightly inward.
Nearly six feet (approx. 1.8 m) up from the floor.
Center: Precisely between the front speakers. (To avoid
interference with TV sets, use a magnetically shielded
speaker. If, however, it is not effective, keep the
speaker away from TV sets.)

control, connect it to this connector by using the cable provided
with the turntable. This connection allows you to control the
turntable from the provided remote control transmitter.
GND terminal (For turntable use)
Connecting the ground wire of the turntable to this terminal will
minimize hum, but in some cases better results may be
obtained with the ground wire disconnected.
FRONT OUT terminals
These terminals are for front-channel line output. Leave the
jumper bars connected to FRONT IN terminals when you use
the built-in amplifier.
However, if you drive front speakers with an external stereo
power amplifier, remove the jumper bars and connect the input
terminals of the external amplifier (MAIN IN or AUX terminals
of a power amplifier or an integrated amplifier) to these
terminals.
FRONT IN terminals
These terminals are for line input to the built-in front-channel
amplifier. Leave the jumper bars connected to FRONT OUT
terminals when you use the built-in amplifier.
However, if you drive front speakers with an external stereo
power amplifier, remove the jumper bars.

ANTENNA CONNECTIONS
●
Each antenna should be connected to the designated terminals correctly, referring to the following figure.
●
Both AM and FM indoor antennas are included with this unit. In general, these antennas will probably provide sufficient signal
strength. Nevertheless, a properly installed outdoor antenna will give clearer reception than an indoor one. If you experience
poor reception quality, an outdoor antenna may result in improvement.
Connecting the AM loop antenna
* The AM loop antenna should be placed apart from the main unit. The antenna may be hung on a wall.
* The AM loop antenna should be kept connected, even if an outdoor AM antenna is connected to this unit.
GND terminal
For maximum safety and minimum interference, connect the
GND terminal to a good grounding. A good grounding is a
metal stake driven into moist earth.
Notes
●
When connecting the indoor
FM antenna, make sure that
the grooved part of the
connector hole is facing
downward.
●
If you need an outdoor FM antenna to improve FM reception
quality, either a 300-ohm feeder or a coaxial cable may be
used. In locations troubled by electrical interference, a
coaxial cable is preferable.

Notes
●
The FRONT EFFECT LEVEL key does not function if the
unit is in the “test” mode. Because the effect sound output
level of the front speakers is used as the basis in speaker
balance adjustment.
●
Once you have completed these adjustments, you can
adjust whole sound level on your audio system by using the
VOLUME control (or the MASTER VOLUME keys on the
remote control transmitter).
●
If you use external power amplifiers, their volume controls
may also be adjusted to achieve proper balance.
●
In step 12, if the center mode is in the “PHANTOM” position,
the sound output level of the center speaker can not be
adjusted. This is because in this mode, the center sound is
automatically output from the left and right front speakers.

Because one or two speaker systems (as front speakers) can
be connected to this unit, the SPEAKERS switches allow you
to select speaker system A or B, or both at once.
When you listen with headphones
Connect the headphones to the PHONES jack. You can listen
to the main sound through headphones. When listening with
headphones privately, set both the SPEAKERS A and B
switches to the OFF position.

TUNING OPERATIONS
Normally, if station signals are strong and there is no interference, quick automatic-search tuning (AUTOMATIC TUNING) is
possible. However, if signals of the station you want to select are weak, you must tune to it manually (MANUAL TUNING).
Display information
➀Displays the band and frequency of the received station.
➁Indicates the signal level of the received station.
➂Illuminates when an FM stereo broadcast with sufficient
signal strength is received.
Select the reception band (FM or AM) while watching
the display.
To tune to a higher frequency, press the right side once.
To tune to a lower frequency, press the left side once.
If the station where tuning search stopped is not the
desired one, follow step 3 again.
* If the tuning search does not stop at the desired station
(because the signals of the station are weak), change to
the MANUAL TUNING method.
Select the reception band (FM or AM) while watching
the display.
Tune to the desired station manually.
* To continue tuning search, press and hold the button.
Note
If you tune to a FM station manually, it is received in monaural
mode automatically to increase the signal quality.

Description of Each Sound Field Program
PROGRAM FEATURE
This program reproduces sources encoded with the Dolby Surround.
PRO LOGIC
The employment of the digital signal processing system improves crosstalk and transfers the sound source
more smoothly and precisely, compared to the conventional type. A stable movie sound field is recreated.
This program reproduces sources encoded with the Dolby Surround.
ENHANCED
Enhancing the “Normal” Dolby Pro Logic, the DSP technology simulates the multi-surround speaker
systems of a 35 mm film theater, thus widening the surrounded-sound field with greater presence.
CONCERT VIDEO
This program is effective for music videos and gives excellent depth and clarity for vocals. For opera, the
orchestra and stage are ideally recreated, letting you feel as if you were in an actual concert hall.
MONO MOVIE
This program is designed specifically to enhance mono source programs. Compared to a strictly mono
setting, the sound image created in this mode is wider and slightly forward of the speaker pair, lending an
immediacy to the overall sound. It is particularly effective when used with old mono movies, news
broadcasts and dialog.
ROCK CONCERT This program is suitable for rock music. A big, powerful sound is reproduced lively and dynamically.
CONCERT HALL
In this program, the center seems even more deeply behind the front speaker pair, creating an expansive,
large hall ambience.
OFF
When any program is not used with the selected source, press this switch.
The sound is output only from the front speakers.
USING DIGITAL SOUND FIELD PROCESSOR (DSP)
This unit incorporates a sophisticated, multi-program digital sound field processor, which allows you to expand and shape the audio
sound field from both the audio and video sources, for a theater-like experience in the listening/viewing room.
This digital sound field processor has 6 programs; 4 programs for digital sound field processing and 2 programs for the Dolby Pro
Logic Surround sound system (DOLBY PRO LOGIC and ENHANCED). You can create an excellent audio sound field by selecting
the suitable program and adding desired adjustments. In addition, when the digital sound field program is in the DOLBY PRO
LOGIC or ENHANCED mode, the built-in automatic input balance control functions. This presents you the best surround condition
without manual adjustment.

Notes on Operation of Sound Field Programs
●
In the CONCERT VIDEO, MONO MOVIE, ROCK CONCERT
and CONCERT HALL modes, no sound is heard from the
center speaker.
●
When a monaural sound source is played in the DOLBY
PRO LOGIC or ENHANCED mode, no sound is heard from
the front speakers and the rear speakers. Sound is heard
only from the center speaker. However, if the center mode is
in the PHANTOM, the front speakers output the sound of the
center speaker.
●
If you connect an external amplifier to this unit, see if it has
built-in surround sound or ambience circuitry. If it does, then
be sure that the surround or ambience circuitry on that
amplifier is off while you are using the digital sound field
processor’s Dolby Pro Logic Surround decoding function.
●
When this unit is in the Dolby Pro Logic Surround mode, if
the main-source sound is considerably altered by
overadjustment of the BASS or TREBLE controls, the
relationship between the center and rear channels may
produce an unnatural effect.
Description of Dolby Pro Logic Surround
DOLBY PRO LOGIC SURROUND: This unit employs the
Dolby Pro Logic Surround system. This system is similar to
professional Dolby Stereo decoders used in movie theaters.
By employing a four-channel system, the Dolby Pro Logic
Surround system divides the input signals into four levels: the
left and right main channels, the center channel (to characterize
dialog), and the rear surround-sound channels (to characterize
sound effects, background noise and other ambient noise).
Dolby Surround is encoded on the sound track of commercially
available video cassettes and video discs as well. When you
play a source encoded with Dolby Surround on your home video
system, the Dolby Pro Logic Surround mode on this unit
decodes the signal and feeds the surround-sound effects.
The Dolby Pro Logic Surround mode may not be always
effective on video sources not encoded with Dolby Surround.
Manufactured under license from Dolby Laboratories Licensing
Corporation. Additionally licensed under one or more of the
following patents: U.S. numbers 3,632,886, 3,746,792, and
3,959,590; Canadian numbers 1,004,603 and 1,037,877.

Adjustment of DELAY TIME
You can adjust the time difference between the beginning of
the source sound and the beginning of the effect sound with
the DELAY TIME control.
The DELAY TIME control is effective with all programs.
By applying more or less delay, sound effects, background
noise, and ambient noise coming at you from the rear speakers
can be enhanced or subdued for extra effect.
1. PRO LOGIC: from 15 to 30 milliseconds
(Preset value: 20 milliseconds)
2. ENHANCED: from 15 to 30 milliseconds
(Preset value: 20 milliseconds)
3. CONCERT VIDEO: from 1 to 100 milliseconds
(Preset value: 25 milliseconds)
4. MONO MOVIE: from 1 to 100 milliseconds
(Preset value: 25 milliseconds)
5. ROCK CONCERT: from 1 to 100 milliseconds
(Preset value: 15 milliseconds)
6. CONCERT HALL: from 1 to 100 milliseconds
(Preset value: 30 milliseconds)
By continuously pressing “+” or “–” on the DELAY TIME
control, the value changes continuously.
However, the value stops changing momentarily at the preset
point.
Note
Adding too much delay will cause an unnatural effect with
some sources. Experiment with the DELAY TIME control to
create the effect that you find most suitable.
Follow step 1–6 shown in “OPERATIONS” on page
13.
Select the desired program that is suitable for the
source.
If desired, adjust the delay time and the output level of
each speaker. (For details, refer to the corresponding
descriptions on this page and the next page.)
Note
If you prefer to cancel the selected program, press the OFF
switch. The sound will be the normal 2-channel stereo without
surround sound effect.
