Wall-Mounting Your Satellites
The satellites may be wall-mounted. The customer is responsible for proper selection and use of mounting hardware available through hardware stores to properly and safely wall-mount the satellites. This product is not intended for ceiling mounting.

1 Speaker Placement
For optimum performance, follow these guidelines when placing the speakers.
Front Speakers
Place the front left and right speakers on the sides of the television. The distance between them should be the same as the distance from the television to the listener. The center-channel speaker should be placed on top of the television.
![graph TD A["Box 1"] --> B["Car"] C["Box 2"] --> B B --> D["Car"] style A fill:#f9f,stroke:#333 style C fill:#f9f,stroke:#333 style B fill:#ccf,stroke:#333 style D fill:#cfc,stroke:#333](/content/2026/07/1440572/images/e32e8bea8239a5254d7b88412f3984767e8d88d8fb4fdc65eace2530984800e8.jpg)
Place the center speaker even with the left and right speakers, or slightly behind them.
Place all three front speakers at approximately the same height (height of ears preferable).

Surround Speakers
The surround speakers should be placed 5'-6' high and parallel to the main listening area, facing each other. Alternatively, they may be mounted on a wall behind the listening area, facing forward.


1 Speaker Placement (Cont.)
On optional stands. Part No. FS10/20.

Subwoofer
The subwoofer should be placed along the front wall. Bass output will increase as the subwoofer is moved closer to a corner.

Rotating logo. Pull out gently and turn.

2 Speaker Connection
To connect your speakers, press down on the quick-release tab, which opens the terminal for the speaker wire, and put the bare end of the wire in straight. Release the tab and give
the speaker wire a gentle tug. If it's in properly, it won't "give" at all. If it slides, repeat the procedure. Use the shortest wire for the CENTER speaker, the two medium-length wires for the
FRONT speakers and the long wires for the REAR speakers. Always insert the RED-coated wire into the RED terminals and the BLACK-coated wire into the
BLACK terminals on each of your speakers and on the appropriate terminal on the back of the Main Unit.

Make sure you match RED to RED and BLACK to BLACK on both ends.
3 Source Connection (TV or VCR)

The ESC230 is equipped with a line-level output that allows you to send the same audio signal to additional audio equipment, such as an amplifier and speakers in another location.
4 DVD Player with Built-In Dolby Digital or DTS® Processor or Outboard Surround Processor

6-Channel Digital Direct
If you have a DVD player or surround processor with a built-in Dolby Digital or DTS processor, connect the 6 outputs of the DVD player/processor as shown. Please check that all 5 satellites and the subwoofer are configured correctly through the DVD player or the outboard processor. Depending on the product you own, you may have to configure these settings using the on-screen display of the DVD player or the outboard processor. Make sure that the satellites are set to On and are in Small mode, and that the subwoofer is also set to On.
5 Source Connection (Headphone)

6 Plug In

7 Turn On
The Master Power Switch should be turned off when the unit will be unused for a long period of time.

Note: The unit will return to default settings when the Master Power Switch is turned off.
8 Surround Modes
Dolby Pro Logic
Use this mode for films recorded using Dolby Surround. The surround channels have a 20-ms delay.
Hall/Concert
These modes create surround sound from stereo recordings. The center channel is not used and the surround channels have a 20-ms delay. Repeated pressing and releasing of the button provides access to these two modes.
Stereo
This mode plays two-channel recordings through the front left and right speakers.
6-Channel Direct Digital
If you have a DVD player or surround processor with a built-in Dolby Digital or DTS processor, this mode will provide the best quality surround-sound presentation.


9 Test Mode and Level Adjustments
Test Tone
The test tone is used to calibrate the level settings of the speakers. A static noise will be heard cycling, in order, from the front left, center, right and both surround speakers. Using the remote control, adjust the Center and Surround levels until the volume of all the speakers is the same during the test. 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 substantial number of effects are reproduced through the center channel.

Troubleshooting
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 connection 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 placement 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.
