If you hear no sound at all:
• Make sure the ESC230
main unit is plugged into a
live electrical outlet and
that the power switch is on.
• Check connections from
the ESC230 main unit to
the TV, VCR, DVD player
and the outboard surround
processor.
• If using with a television
or outboard surround
processor, make sure that
the TV or the surround
processor is on and a
signal is present.
• If using with a VCR,
make sure the VCR is
playing a tape.
• If using a DVD player,
make sure that the DVD
is playing.
• If using the 6-channel
digital direct inputs, make
sure that the 6-channel
mode is selected and its
indicator is illuminated on
the display. There will be
no output if the product is
in any other mode.
• If using the conventional
right and left inputs 1 or
2, make sure that Dolby
Pro Logic, Hall, Concert or
Stereo mode is selected
and its indicator is
illuminated in the display.
There will be no output if
the product is in the 6-
channel mode. Also make
sure that the appropriate
input (1 or 2) is selected as
illuminated in the display.
• Check all connections
between the ESC230
main unit and each of
the speakers.
If one or more of the speakers
does not play:
• Check all connections
between the ESC230
main unit and each of
the speakers.
• Adjust the balance
controls from left to right
and front to rear.
If you have very little bass
output:
• Make sure the subwoofer
is connected properly to
the ESC230 main unit.
• Experiment with place-
ment of the subwoofer.
Remember, place the
subwoofer in a corner
to get maximum bass
output from the system.
• Make sure Bass Boost
is on.
• Adjust Bass level.
If there is no sound coming
from the rear speakers or the
volume is very low:
• Check all connections
between ESC230 main unit
and each of the speakers.
• Adjust the front-rear
balance controls on the
ESC230 main unit.
• Make sure the TV show or
movie you are watching is
recorded in Dolby Surround.
If it is not, try the Concert
Hall or Stereo settings on
the ESC230 main unit.
When using the 6-channel
digital direct inputs, if there
is no sound coming from
some channels:
• Make sure that all 6
connectors are securely
connected on both the DVD
player/outboard processor
side and the ESC230 side.
• Make sure that the DVD
player/outboard processor’s
built-in decoder is correctly
configured to provide
output to all 5 satellites
and the subwoofer.
(Depending on the product
you own, you may have to
do this using that specific
product’s on-screen
display.) Make sure that the
satellites are set to Small
and the subwoofer is set
to On by checking the
settings of the DVD player
or outboard surround
processor.
