CONNECTIONS
Connecting to 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 PRE OUT/MAIN IN jacks as follows.
Note
• When RCA pin plugs are connected to the PRE OUT/MAIN
IN jacks for output to an external amplifier, it is not necessary
to use the corresponding SPEAKERS terminals.

MAIN OUT/IN jacks
MAIN OUT
jacks .... Main channel line output jacks.
The signals output through these
jacks are affected by VOLUME,
BASS, TREBLE, and BASS
EXTENSION settings.
MAIN IN

channel amplifiers.
When connecting to these jacks, signals input to the
preamplifier of this unit will not be output from the main

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 if they
are assigned to this jack. (The cut-off frequency of this
jack is 90 Hz.) The LFE (low-frequency effect) signals
generated when Dolby Digital or DTS is decoded are also
directed if they are assigned to this jack.
Notes
• Adjust the volume level of the subwoofer with the control on
the subwoofer. It is also possible to adjust the volume level by
using the remote control of this unit (see ADJUSTING THE
LEVEL OF THE EFFECT SPEAKERS on page 67).
• Depending on the settings of “1 SPEAKER SET” and “10 LFE
LEVEL” on the SET MENU, some signals may not be output
from the SUBWOOFER jack.

Connecting an External Decoder
This unit is equipped with 6 additional input jacks (left
and right MAIN, CENTER, left and right SURROUND
and SUBWOOFER) for discrete multi-channel input from
an 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.
Notes
• When you select 6CH INPUT as the input source, this unit
automatically turns off the digital sound field processor, and
you cannot listen to DSP programs.
• When you select 6CH INPUT as the input source, settings of
“1 SPEAKER SET” on the SET MENU do not apply (except
for 1F MAIN LEVEL).
