PREPARATION
To drive main, center and/or rear speakers with external amplifiers
The speaker connections described on page 20 are fine for
most applications. If for some reason, however, you wish to
drive main, center and/or rear speakers with your existing
amplifier, etc., the following terminals are available for
connecting external amplifier(s) to this unit.
MAIN
1 2
1
MAIN terminals
These terminals are for main channel line output.
If you drive main speakers with an external stereo power
amplifier, connect the input terminals of the external
amplifier (MAIN IN or AUX terminals of an amplifier or a
receiver) to these terminals.
There is no connection to these terminals when you use
the built-in amplifier.
* Output signals from the MAIN terminals are affected by
the use of BASS, TREBLE, BALANCE controls, BASS
EXTENSION button and the TONE BYPASS button.
2
SUBWOOFER terminal
When using a subwoofer, connect its amplifier input to
this terminal. Low frequencies distributed from the main,
center and/or rear channels are output from this terminal.
(The cut-off frequency of this terminal is 90 Hz.) Signals
of LFE (low frequency effect) generated when Dolby
Digital or DTS is decoded are also output if they are
assigned to this terminal.

CENTER terminal
This terminal is for center channel line output.
If you drive a center speaker with an external power
amplifier, connect the input terminal of the external
amplifier to this terminal.
There is no connection to this terminal when you use the
built-in amplifier.
4
REAR (SURROUND) terminals
These terminals are for rear channel line output.
If you drive rear speakers with an external stereo power
amplifier, connect the input terminals of the external
amplifier (MAIN IN or AUX terminals of an amplifier or a
receiver) to these terminals.
There is no connection to these terminals when you use
the built-in amplifier.
Notes
• Output level of signals from all of these terminals are
adjusted by the use of VOLUME control on the front panel
or VOLUME keys on the remote controller.
• If an external power amplifier is connected to the MAIN,
CENTER, or REAR output terminals, do not use the
corresponding SPEAKERS terminals (MAIN, CENTER, or
REAR).
