For proper Dolby Pro Logic
operation, a test tone 
is used to calibrate the 
volume settings of the
speakers. A noise will be
heard cycling, in order,
from the front left, center,
right, and both surround
speakers.
Using the remote control,
push “Tone.” Then adjust
the Center and Surround
levels until the volume 
of all the speakers is the 
same during the test.
Note: The test tone is 
used to calibrate the 
performance of the system.
When listening to an actual
recording, the volume level
of the surround channels is
generally much lower than
that of the front channels.
In fact, when listening to a
movie, virtually all of the
dialogue and a substantial
number of the effects are
reproduced through the
center channel.

Delay Time
The delay control allows
the user to set the sur-
round delay between 15
and 30 milliseconds in 
one-millisecond increments.
The best setting will
depend on the distance
between the main 
listening area and the
front speakers as well as
the distance between the
main listening area and 
the rear speakers. The chart
at the bottom shows the
recommended settings.

If there is no sound from any
of the speakers, check the
following:
• Make sure the subwoofer is
plugged into an active AC wall 
outlet.
• Make sure the Master Power
Switch, located on the rear of the
subwoofer, is in the 
On/Standby
position.
• Make sure there is a source –
for example, a VCR or television –
hooked up to the TV or tape/aux
input jacks on The Source.
• Make sure that the program 
material is playing.
• Recheck the hookup connec-
tions.
If most of the sound comes from
the center-channel speaker, with
little or no information from 
the surround channels, note the 
following:
Although most of today’s televi-
sions are equipped with stereo
audio output jacks, some stereo
televisions have poor audio sec-
tions and are unable to provide a
Dolby Pro Logic encoded signal. In
the unlikely event that you experi-
ence this problem, connecting the
audio outputs from your hi-fi VCR,
laser disc player, DVD player, or
satellite receiver directly to one of
the inputs on The Source will pro-
vide a proper audio signal and
allow you to enjoy true Dolby Pro
Logic surround sound.
If there is no sound from the
surround speakers or sound is
very low, check the following:
• Check all connections between
the amplifier and each of the
speakers.
• Raise the surround volume 
from the remote control 
(see 
Operation
section).
• Make sure the TV show or movie 
you are watching is recorded in
Dolby Surround.
If there is no sound from the
center speaker, check the
following:
• Make sure that the processor 
is in the Pro Logic mode. If it is 
in Phantom or Stereo mode, the
center speaker will not play.
• Check the connections between 
the subwoofer and the center
speaker.
If you have low bass output,
check the following:
• Experiment with placement of 
the subwoofer. Remember, place
the subwoofer in a corner to get
maximum bass output from the
system.
• Increase the level of bass,
using the remote control.
• Adjust the level control on the 
rear of the subwoofer.
If you are having trouble picking
up radio stations, check the
following:
• Make sure the antenna is 
hooked up properly.
• Depending on your distance from
the station’s transmitter, you may
need to install an FM antenna on 
the roof or in the attic.
