JBL ESC550 - Manual (Page 22)

– 22 –
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
connections.
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
televisions are equipped with
stereo audio output jacks,
some stereo televisions have
poor audio sections 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 receiv-
er directly to one of the inputs
on The Source will provide 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
it is very low, check the
following:
• Check all connections
between 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, or
3 Stereo 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.
