The delay control allows the
user to set the surround delay
between 15 and 30 milli-
seconds. 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 on the right shows
the recommended settings.

For proper Dolby Pro Logic
operation, a test tone is used
to calibrate the volume set-
tings 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
“Test 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 sub-
stantial number of the effects
are reproduced through the
center channel.

Push “Center Level” 

or 

until the volume of the center
speaker is the same as that of
the left and right speakers.

Push “Rear Level” 

or 

until the volume of the rear
speaker is the same as that of
the left and right speakers.

Press “Center Mode” on the
receiver 

Normal: Select this mode 
if you use a small center
speaker. The bass sound of the
center channel is reproduced
from the front left and right
speakers because the small
speaker cannot produce
enough bass.
Wide: Select this mode if you
use a medium-to-large center
speaker. The bass sound is
reproduced from the center
speaker.

Phantom: Select this mode 
if you don’t use a center
speaker. The center speaker’s
sound is reproduced from the
front left and right speakers.
