windows, heat sources, and too much vibration, dust,
moisture or cold. Avoid sources of hum (transformers,
motors). To prevent fire or electrical shock, do not
expose to rain and water.
8
To prevent lightning damage, pull out the power cord
and remove the antenna cable during an electrical
storm.
9
When not planning to use this unit for long periods
of time (ie., vacation, etc.), disconnect the AC power
plug from the wall outlet.
3
Do not operate the unit upside-down. It may overheat,
possibly causing damage.
4
Never open the cabinet. If a foreign object drops into
the set, contact your dealer.
5
Do not use force on switches, knobs or cords. When
moving the set, first turn the unit off. Then gently
disconnect the power plug and the cords connecting to
other equipment. Never pull the cord itself.
6
2
Do not attempt to clean the unit with chemical solvents;
this might damage the finish. Use a clean, dry cloth.
10 Be sure to read the “Troubleshooting” section on
common operating errors before concluding that your
unit is faulty.
11 Do not connect audio equipment to the AC outlets on
the rear panel if that equipment requires more power
than the outlets are rated to provide.

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.

CONNECTING SPEAKERS
Connect the SPEAKERS terminals to your speakers with wire
of the proper gauge, cut 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.
●
●
●
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.
How to Connect:
Red: positive (+)
Black: negative (–)
➁
➀ Unscrew the knob.
➁ Insert the bare wire.
➂
➀
[Remove approx. 5mm
(1/4”) insulation from
the speaker wires.]
➂ Tighten the knob and
secure the wire.
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 signalprocessing system such as a graphic equalizer or sound
processor.
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.
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.
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.

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.
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.

Battery replacement
If you find that the remote control transmitter must be used
closer to the main unit, the batteries are weak. Replace both
batteries with new ones.
Notes
● Use only AA, R6, UM-3 batteries for replacement.
● Be sure the polarities are correct. (See the illustration inside
the battery compartment.)
● Remove the batteries if the remote control transmitter will
not be used for an extended period of time.
● If batteries leak, dispose of them immediately. Avoid
touching the leaked material or letting it come in contact with
clothing, etc. Clean the battery compartment thoroughly
before installing new batteries.

Notes
● There should be no large obstacles between the remote
control transmitter and the main unit.
● 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
direct lighting.

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
REMEDY
Power cord is not plugged in or is not
completely inserted.
