6 Channel Input Jacks

When the ADP303 is used with an
external preamplifier, an outboard
surround processor or any AV
receiver with PREAMP-OUT/MAIN-
INPUT jacks, connect these jacks
to the outputs of the preamp or
processor.

6 Channel Output Jacks

These jacks deliver the outputs of
the AC-3 decoder or pass through
the inputs from a preamplifier/
processor (see item 4) when the
ADP303 is in the BYPASS mode.
Depending on your application, they
will either be connected to the “6
Channel Direct” inputs of products
such as the AVR80 or directly to
external power amplifiers .

Front SPK Switch

This switch determines if low
frequency signals are sent to the
front left/right speakers. The factory
default “Small” sends them to the
subwoofer output only, while “Large”
sends a full range signal to the front
left/right speakers.

Surr SPK Switch

This switch determines if low
frequency signals are sent to the
surround speakers. The factory
default, “Small,” sends them to the
subwoofer output only, while “Large”
sends a full range signal to the
surround speakers. Select “none” if
you will not use surround speakers
and to route surround audio to the
front left/right speakers.

•

Center SPK Switch

This switch determines if low
frequency signals are sent to the
center speaker. The factory default ,
“Small,” sends them to the
subwoofer output only, while “Large”
send a full range signal to the center
speaker. Select “none” if you will not
use a center speaker and to route
center channel audio to the front
left/right speakers.

Subwoofer switch

This switch, in conjunction with the
other “SPK” switches, directs the
output of low frequency (LFE)
signals. If a subwoofer is used,
select “ON” to send all system
sound below 100 Hz to the
subwoofer output. If the “OFF”
position is used, the LFE output will
be directed to either the front
left/right or center speaker outputs,
depending on the position of
switches
