Installation & Setup
8
Use this setup for connection to an AVR80,
AVI250 or other compatible products
equipped with 6 Channel Direct inputs.
1. Connect the AC-3 RF output of a
compatible LV player to the ADP303 AC-3
RF In Jack
¡
.
2. Connect the optical or coax AC-3
output of a DSS, DVD player or HDTV
receiver to the respective input jack
™£
on the ADP303.
3. Connect the Analog Line Outputs of
the Laser Disc player to the LD inputs of
the receiver.
4. Connect the PCM output of the Laser
Disc player (if equipped) to the LD
Digital input of the AVR80.
5. Connect the Line Out
∞
jacks of the
ADP303 to the 6 Channel Direct inputs of
the AVR80.
6. Set the Speaker Mode switches
§¶•ª
to their proper positions
based on the type of speakers in use.
7. Using the small Allen Key tool supplied
with the ADP303, carefully remove the
cover panel for the Level Trim Controls
˙
. Set the cover aside so that you may
replace it later.
8. Turn on the power to both the ADP303
and the receiver or amplifier. Before pro-
ceeding further, make certain that the
output levels on the receiver or amplifier
have been properly adjusted.
9. Press the 6ch Direct Input button of
the AVR80 or AVI250.
10. Set the Main Volume Control
î
on
the ADP303 to the 12 o’clock position.
11. Press the Test button
ƒ
and hold it
for a few seconds. This will start the test
tone sequence.
Note that a test signal noise will be heard
from the speakers. Verify that test signal
circulates in a clockwise direction, stop-
ping for five seconds at each speaker. If
the sound is heard out of order, (i.e.,
moving from right to left, or appearing
out of order), turn the unit off and check
the connection from the ADP303 output
jacks to the inputs of your AV receiver.
12. Listen to the sound as it moves
between the speakers. Ideally, the output
from each speaker should be equal. If the
output is NOT equal change the level by
carefully turning the Output Level Trim
Control
˙
for the speaker that needs
adjustment.
13. When you have completed the adjust-
ments press “Test” button
ƒ
once to
stop the Test Tone.
14. Carefully replace the cover for the
Level Trim Controls.
15. During normal operation use the
AVR80 or AVI250 volume control to
adjust the volume level.
