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.

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.
