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.
How to Connect:
Red: positive (+)
Black: negative (–)
●
●
●
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.
*When connecting Banana Plugs to this unit’s SPEAKERS
terminals, be sure to tighten the terminal knobs to make
contact securely before connections.
➁
➀ Unscrew the knob.
➁ Insert the bare wire.
➂ Tighten the knob and
secure the wire.
➂
➀
Caution
When inserting the stripped ends of the speaker wires
as shown above, make sure at least 1/16 inch (1.6 mm)
of insulation is inside the wire holders (i.e. no exposed
wire is visible) and no loose conductor wire strands
are protruding after connection. If wires touch each
other or they touch the metal parts of this unit, this
unit and/or speakers could be damaged. To prevent
speaker wires from coming loose, make sure wire
holders are firmly screwed in.
REMOTE CONTROL (PRE AMP) connector
If you have the YAMAHA pre-amplifier CX-1 or CX-2, connect
this connector to the REMOTE CONTROL (POWER AMP)
connector of the pre-amplifier by using the cable provided with
the pre-amplifier. By this connection, the power of this unit is
controlled by the pre-amplifier’s POWER switch or the POWER
key of the remote control transmitter provided with the preamplifier.
After the connection is completed, keep the POWER switch of
this unit pressed inward (to the ON position).
Note
If you will not connect the REMOTE CONTROL connectors of
this unit and the pre-amplifier, do not connect the cable to
either connector. Otherwise, this unit will not function normally.

These controls adjust the level of signals input to this unit.
Normally set these controls to the “10” (maximum) position,
and adjust the whole sound output level with the VOLUME
control of the pre-amplifier. However, if your speakers’
permissible music input power is not high enough or sounds
from the speakers are distorted, turn these controls
counterclockwise to decrease the level.
Note
To turn the power off completely, disconnect the AC
power plug from the wall outlet.
