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.
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.
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.
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.

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.)
SPEAKER PLACEMENT
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.)
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.
6
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.)
CONNECTIONS
Before attempting to make any connections to or from this unit, be sure to first switch OFF the power to this unit and to any other
components to which connections are being made.
CONNECTIONS WITH OTHER COMPONENTS

CONNECTING SPEAKERS
Connect the SPEAKERS terminals to your speakers with wire
of the proper gauge, cut to be as short as possible. If the
connections are faulty, no sound will be heard from the
speakers. Make sure that the polarity of the speaker wires is
correct, that is, + and – markings are observed. If these wires
are reversed, the sound will be unnatural and will lack bass.
Do not let the bare speaker wires touch each other and do
not let them touch the metal parts of this unit as this could
damage this unit and/or speakers.
●
Use speakers with the specified impedance shown on the
rear of this unit.
How to Connect:
