ADDING A SUBWOOFER

You may wish to add a subwoofer to reinforce the bass

frequencies.

This unit provides a line-level subwoofer output, which contains

only the frequencies under 200 Hz from the main and center

channels. Connect the LOW PASS jack to the INPUT jack of the

subwoofer amplifier, and connect the speaker terminals of the

subwoofer amplifier to the subwoofer.

With some subwoofers, including the Yamaha Active Servo

Processing Subwoofer System, the amplifier and subwoofer are in

the same unit.

CONNECTING SPEAKER SYSTEMS

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

or any other metal part as this could damage this unit and/or

speakers.

NOTE: Use speakers with the specified impedance shown on the

rear of this unit.

NOTE: Banana Plug connections are also possible (except for

Europe model). Simply insert the Banana Plug connector into the

corresponding terminal.

Red: positive (+)

Black: negative (–)

Unscrew the knob.

Insert the bare wire.

Tighten the knob and

secure the wire.
