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

OUTLETS is 100 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.
PRE OUT/MAIN IN terminals
<For AX-570 only>
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 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
