Press this button to start
the “test sound” generator. Use
this test sound to position all the

The test sound moves in
sequence from the left Satellite,
the Center Speaker, the right
Satellite, then to the rear right
Satellite, rear left Satellite and
the subwoofer. All indicator lights
will blink on and off while the
test sound generator is in
operation.
The test sound will operate for
three complete cycles and then
stop. You can terminate the
sound at any point by pressing
the Test button again.
First use the test sound to
verify that each speaker is
operating.
Then make sure the speakers
are positioned so that the test
sound can be clearly heard.
Finally, adjust the front panel
level controls for the Center,
Subwoofer and rear Satellites.
Adjust each control so its speaker
achieves a balanced output level
with the left and right satellites
