We Want You Listening For A Lifetime
YAMAHA and the Electronic Industries Association’s
Consumer Electronics Group want you to get the most out of
your equipment by playing it at a safe level. One that lets the
sound come through loud and clear without annoying blaring or
distortion – and, most importantly, without
affecting your sensitive hearing. Since hearing
damage from loud sounds is often undetectable
until it is too late, YAMAHA and the Electronic
Industries Association’s Consumer Electronics
Group recommend you to avoid prolonged
exposure from excessive volume levels.

One or two speaker systems can be connected to this unit.
If you connect only one speaker system, connect it to either
the SPEAKERS A or B terminals.
Use speakers with the specified impedance shown on the
rear of this unit.
Banana Plug connections are also possible (except for
Scandinavian models). Simply insert the Banana Plug
connector into the corresponding terminal.
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.

ABOUT THE ACCESSORY TERMINALS
AC OUTLETS (SWITCHED)
PRE OUT/MAIN IN terminals
(Europe and General models) ............3 SWITCHED OUTLETS
(Australia and U.K. models)..................1 SWITCHED OUTLET
Removing the jumper pins enables this unit to independently
perform the functions of a control amplifier and a power
amplifier. These terminals are for connection of a signal-
processing system such as a graphic equalizer or sound
processor.
Use these to connect the power cords from your components
to this unit.
The power to the SWITCHED outlets is controlled by this unit’s
POWER switch or the provided remote control transmitter’s
POWER key. These outlets will supply power to any
component whenever this unit is turned on.
The maximum power (total power consumption of
components) that can be connected to the SWITCHED AC
OUTLETS is 200 watts.
If a sound processor or other component is connected, the
VOLUME control of this unit can be used for overall
adjustment of the level of sound. To connect such a unit,
remove the jumper pins from the PRE OUT/MAIN IN terminals,
connect the inputs of that unit to the PRE OUT terminals and
its outputs to the MAIN IN terminals. For details, refer to the
owner’s manual included with the unit to be connected.
REMOTE CONTROL (PHONO) connector
If you have a YAMAHA turntable with a terminal for remote
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
normally minimize hum, but in some cases better results may
be obtained with the ground wire disconnected.

Setting the PHONO switch
Using the PURE DIRECT switch
Select either MM or MC position depending on your PHONO
cartridge, Moving Magnet or Moving Coil type. However, if you
use a high output MC cartridge, select MM position.
You can enjoy the purest possible sound from your audio
sources by setting this switch so that the indicator illuminates.
By doing so, the audio signal bypasses the BASS, TREBLE,
BALANCE and LOUDNESS controls, the SUBSONIC FILTER
switch and the PRE OUT/MAIN IN terminals, eliminating any
alterations to the audio signal.

If the remote control sensor is directly illuminated by strong
lighting (especially an inverter type of fluorescent lamp etc.),
it might cause the remote control transmitter not to work
correctly. In this case, reposition the main unit to avoid

TROUBLESHOOTING
If the unit fails to operate normally, check the following points to determine whether the fault can be corrected by the simple
measures suggested. If it cannot be corrected, or if the fault is not listed in the SYMPTOM column, disconnect the power cord and
contact your authorized YAMAHA dealer or service center for help.
SYMPTOM
CAUSE
REMEDY
The unit fails to turn on when the POWER
switch is pressed.
Power cord is not plugged in or is not
completely inserted.
Firmly plug in the power cord.
No sound.
Incorrect output cord connections.
Appropriate input source is not selected.
Speaker connections are not secure.
Connect the cords properly. If the problem
persists, the cords may be defective.
Select an appropriate input source with the
INPUT selector.
Secure the connections.
The sound suddenly goes off.
The protection circuit has activated because
of short circuit etc.
Turning the unit off and then on will reset the
protection circuit.
Only one side speaker outputs the sound.
Incorrect setting of the BALANCE control.

Set the LOUDNESS control to the FLAT
position.
The MUTING switch is ON.
First, turn the volume control to the full left.
Then, turn the MUTING switch OFF with the
remote control transmitter and adjust the
volume.
Using the BASS, TREBLE, BALANCE,
LOUDNESS controls and SUBSONIC
FILTER switch does not affect the tone.
The PURE DIRECT switch is ON.
The PURE DIRECT switch must be switched
OFF to use those controls.
The remote control transmitter does not
work.
Direct sunlight or lighting (of an inverter type
of flourescent lamp etc.) is striking the
remote control sensor of the main unit.
Change position of the main unit.
The distance or range within which the
remote control transmitter can be used
decreases.
The batteries of this remote control
transmitter are too weak.
Replace the batteries with new ones.
