ADDING A SUBWOOFER
You may wish to add a subwoofer to reinforce the bass
frequencies.
This unit provides line-level subwoofer outputs, which contain only
the frequencies under 200 Hz from the main and center channels. If
you use one subwoofer, connect the MONO LOW PASS jack to the
INPUT jack of the subwoofer amplifier, and connect the speaker
terminals of the subwoofer amplifier to the subwoofer.
If you wish to obtain more presence in your listening room, the
use of two subwoofers is recommended. To connect two subwoofers
to this unit, connect the “left” SPLIT LOW PASS jack to the INPUT
jack of the amplifier driving the left subwoofer, and the “right” SPLIT
LOW PASS jack to the INPUT jack of the amplifier driving the right
subwoofer, and then connect each subwoofer to the corresponding
amplifier.
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.
Red: positive (+)
Black: negative (–)
1 Unscrew the knob.
2 Insert the bare wire.
3 Tighten the knob and
secure the wire.
NOTE: Use speakers with the specified impedance shown on the
rear of this unit.
NOTE: Banana Plug connections are also possible (except for
Scandinavian models). Simply insert the Banana Plug connector into
the corresponding terminal.
