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.
How to Connect:
Red: positive (+)
Black: negative (–)
➀
Unscrew the knob.
➁
Insert the bare wire.
[Remove approx. 5mm
(1/4”) insulation from
the speaker wires.]
➂
Tighten the knob and
secure the wire.
●
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.
●
<General model only
>
Banana Plug connections are also possible. Simply insert
the Banana Plug connector into the corresponding terminal.
CONNECTING SPEAKERS
ABOUT THE OTHER REAR PANEL PARTS
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.
PRE OUT/MAIN IN terminals
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.
If a sound processor or other external unit is connected
between these terminals, 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.
Notes
●
If you will not use the PRE OUT/MAIN IN terminals, never
remove the jumper pins from these terminals. If removed,
no sound will be output from this unit.
●
If you will use this unit with an external unit connected
between the PRE OUT and MAIN IN terminals, make sure
that the PURE DIRECT switch on the front panel is turned
off.
●
If you will use this unit as a power amplifier, connect the
outputs of an external control amplifier etc. to this unit’s
MAIN IN terminals. In that case, this unit’s controls will not
function except the PHONES jack and the SPEAKERS
switches, so use the controls on the external control
amplifier to make volume adjustment etc.

Adjusting the BASS and TREBLE
controls
Adjusting the BALANCE control Selecting the SPEAKER system
Adjust the balance of the output volume to the left and right
speakers to compensate for sound imbalance caused from
speaker location or listening room conditions.
Because one or two speaker systems can be connected to this
unit, the SPEAKERS switches allow you to select speaker
system A or B, or both at once.
BASS : Turn this clockwise to increase (or counter-
clockwise to decrease) the low frequency
response.
TREBLE : Turn this clockwise to increase (or counter-
clockwise to decrease) the high frequency
response.
These switches can be used to adjust the turnover point of the
tone controls: either 200 Hz or 400 Hz for BASS and either 2.5
kHz or 5 kHz for TREBLE. This gives you flexible control over
bass and treble response characteristics.
Adjusting the continuously variable
LOUDNESS control
This control provides compensation for the human ears’ loss of
sensitivity to high and low-frequency ranges at low volume.
This control is adjustable to retain full tonal range at any
volume level.
1 Set to the “FLAT” position.
2 Set to the loudest listening level that you would listen to.
3 Turn until the desired volume is achieved.

Using the PURE DIRECT switch
You can enjoy the purest possible sound from your audio
sources by setting this switch so that the indicator lights up. By
doing so, the audio signals bypass the BASS, TREBLE,
BALANCE, LOUDNESS controls, SUBSONIC FILTER switch,
MODE switch and the PRE OUT/MAIN IN terminals, thus
eliminating any alterations to the audio signals.
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.
To select the MC position, press this switch so that it is held
inward. To select the MM position, press this switch so that it is
released outward.
If you set this switch to “ON” position, undesirable ultra-low-
frequency signals caused by turntable rumble or warped
records can be cut out without losing sound quality.

NOTES ABOUT THE REMOTE CONTROL TRANSMITTER
Battery installation
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.
Remote control transmitter operation range
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.
