Connecting an external amplifier
If you want to increase the power output to the speakers,
or want to use another amplifier, connect an external
amplifier to the OUTPUT jacks as follows.
Note
• When RCA pin plugs are connected to the OUTPUT jacks for
output to an external amplifier, signals are output from the
SPEAKERS terminals as well.
1 SUBWOOFER jack
When using a subwoofer with built-in amplifier,
including the YAMAHA Active Servo Processing
Subwoofer System, connect the input jack of the
subwoofer system to this jack. Low bass signals
distributed from the main, center and/or rear channels are
directed to this jack in accordance with your SPEAKER
SET selections. The LFE (low-frequency effect) signals
generated when Dolby Digital or DTS is decoded are also
directed to this jack in accordance with your SPEAKER
SET selections.
Notes
• The cut-off frequency of the SUBWOOFER jack is 90 Hz.
• If you do not use a subwoofer, designate the signals to the main
left and right speakers by changing the settings of SPEAKER
SET item “1E BASS” on the SET MENU.
• Use the control on the subwoofer to adjust its volume level. It
is also possible to adjust the volume level by using this unit’s
remote control (see “ADJUSTING THE LEVEL OF THE
EFFECT SPEAKERS” on page 51).
2 MAIN jacks

Note
• The signals output through these jacks are affected by the
BASS and TREBLE settings.
3 REAR CENTER jack

Connecting an external decoder
This unit is equipped with 6 additional input jacks (MAIN

external decoder, sound processor, or pre-amplifier.
Connect the output jacks on your external decoder to the
6CH INPUT jacks. Be sure to match the left and right
outputs to the left and right input jacks for the main and
surround channels.

automatically turns off the digital sound field processor, and
you cannot listen to DSP programs.

“1 SPEAKER SET” on the SET MENU do not apply (except
for “1F MAIN Lv”).
