English
The speaker connections described on page 18 are fine for
most applications. If for some reason, however, you wish to
drive main, center, front effect and/or rear speakers with your
existing amplifier, etc., the following terminals are available for
connecting external amplifier(s) to this unit.
1 MAIN CH PRE OUT/MAIN IN terminals
The PRE OUT terminals are for main channel line output,
and the MAIN IN terminals are for line input to the built-in
main channel amplifier. The PRE OUT and MAIN IN
terminals must be connected with jumper bars when the
built-in amplifier is used.
However, if you drive main speakers with an external
stereo power amplifier, first remove the jumper bars, and
then connect the input terminals of the external amplifier
(MAIN IN or AUX terminals of an amplifier or a receiver)
to the PRE OUT terminals. No connection is needed to
the MAIN IN terminals.
* Output signals from the PRE OUT terminals are
affected by the use of BASS, TREBLE, BALANCE
controls and BASS EXTENSION switch.
2 CENTER OUT/IN terminals
The CENTER OUT terminals are for center channel line
output, and the CENTER IN terminal is for line input to the
built-in center channel amplifier.
The lower side of CENTER OUT terminals and the
CENTER IN terminal must be connected with a jumper
bar when the built-in amplifier is used.
However, if you drive one or two center speakers with an
external power amplifier (for each), first remove the
jumper bar, and then connect the input terminal(s) of the
external amplifier(s) to either or both CENTER OUT
terminals. No connection is needed to the CENTER IN
terminal.
3 SUBWOOFER terminals
SUBWOOFER MONO terminal
When using a subwoofer, connect its amplifier input to
this terminal. Frequencies below 90 Hz distributed from
the main, center and/or rear channels are output from this
terminal. Signals of LFE (low frequency effect) generated
when the Dolby Digital (AC-3) or the DTS is decoded are
also output if they are assigned to this terminal.
SUBWOOFER SPLIT terminals
When using two subwoofers, connect their amplifier
inputs to these terminals. Low bass signals that are
output from the SUBWOOFER MONO terminal are also
output from these terminals. However, signals from the
left main and left rear channels are output to the SPLIT L
terminal, and signals from the right main and right rear
channels are to the SPLIT R terminal separately.
4 FRONT terminals
These terminals are for front effect channel line output.
There is no connection to these terminals when you use
the built-in amplifier.
However, if you drive front effect 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.
5 REAR (SURROUND) terminals
These terminals are for rear channel line output. There is
no connection to these terminals when you use the built-
in amplifier.
However, 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.
Notes
Output level of signals from all of these terminals are
adjusted by the use of VOLUME control on the front panel
or MASTER VOLUME keys on the remote control
transmitter.
If an external power amplifier is connected to the FRONT
or REAR output terminals, the corresponding internal
amplifier will be turned off and no output will be available
at the SPEAKERS terminals.
