Connecting to an External
Amplifier
If you want to increase the power output to the speakers,

output to an external amplifier, it is not necessary to use the
corresponding SPEAKERS terminals.

MAIN jacks
Main channel line output jacks.
Note
• The signals output through these jacks are affected by the
BASS, TREBLE and BASS EXTENSION settings.
2
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. (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. The subwoofer volume cannot be adjusted from
this unit.
• Depending on the settings of “1 SPEAKER SET”, “10A LFE
LEVEL” and “11 DTS 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, changing
items 1A to 1E on the SET MENU is not affected.
