Test tone, Balance, Center channel volume – JBL ESC550 User Manual
Page 18
– 18 –
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
“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.
