If the problem is in the same place, the source of the problem is most likely with your receiver or amplifier, and you should consult the owners manual for that product for further information. If theproblem has followed the speaker, consult your dealer for further assistance or, if that is not possible, visit our Web site at for further information. If there is no sound from Check all wires and connections between receiver/amplifier and speaker. Make sure all wires are connected. the center speaker:Make sure none of the speaker wires are frayed, ccut, punctured, or touching other wires. If your receiver/processor is set in Dolby Pro Logic mode, make sure the center speaker is not in phantom mode. If your receiver/processor is set in Dolby Digital or DTS mode, make sure the receiver/processor is configured so that the center speaker is enabled. If the system plays at low Check all wires and connections between receiver/amplifier and speakers. Make sure all wires are connected. volumes but shuts off as Make sure none of the speaker wires are frayed, cut, punctured, or touching other wires. volume is increased: If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier. If there is low (or no) bass Make sure the SUB or Line-Level Inputs of the SUB-TS7 subwoofer and SUB or LFE output of your receiver output:or amplifier are properly connected by the RCA-type interconnect cable. If you are using the SUB-TS7s Speaker-Level Inputs , check your speaker cables to make sure they are all connected; that none of the wires are frayed, cut, punctured, or touching other wires; and that you have maintained the correct polarity by connecting positive terminals to positive terminals, and negative terminals to negative terminals. Make sure the subwoofer is plugged into an active electrical outlet and its Master Power Switch is switched on to the “” position. Check the speaker setup (bass management) settings in your A/V receiver or processor to make certain that the front, center and surround speakers are configured for “Small,” and that the subwoofer is set for “Yes” or “On.” If there is no sound from Check all wires and connections between receiver/amplifier and speakers. Make sure all wires are connected. Make sure the surround speakers:none of the speaker wires are frayed, cut, punctured, or touching other wires. Review proper operation of your receiver/processor and its surround sound features. Make sure the movie or TV show you are watching is recorded in a surround sound mode. If it is not, check to see whether your receiver/processor has other surround modes you may use. In Dolby Digital or DTS mode, make sure your receiver/processor is configured so that the surround speakers are enabled. Review the operation of your DVD player and the jacket of your DVD to make sure that the DVD features the desired Dolby Digital or DTS mode, and that you have properly selected that mode using both the DVD players menu and the DVD discs menu.

Use a Y-cable from a mono source if necessary to connect to both inputs. Do not connect to the single, purple SUB input. 2) Turn on generator; adjust to 75mV, 50 Hz. 3) Plug in UUT; turn the power switch ON. Turn LEVEL control full clockwise (MAX) 4) LED should turn from Amber to Blue (on top of UUT); immediate and vigorous bass response should be heard and felt from port tube opening. 5) Turn off generator, turn LEVEL control full counterclockwise (MIN), and disconnect RCA cable. 6) Connect one pair of speaker cables to Speaker Level input terminal (IN) on UUT. Cables should be connected to an integrated amplifier fed by the signal generator. 7) Turn on generator and adjust so that speaker level input at the amplifier is 1.6V, 50 Hz. Turn LEVEL control full clockwise. 8) LED should turn from Amber to Blue; immediate and vigorous bass response should be heard and felt from the port tube opening. Sweep Function 1) Follow steps 6-8 above, using a sweep generator as a signal source. 2) Sweep generator from 20Hz to 300Hz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or any other noises. If any unusual noises are heard, remove woofers and test. Driver Function 1) Remove woofer from cabinet; detach + and - wire clips. 2) Check DC resistance of woofer; it should be 3.0 ohms 10% 3) Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 5.0V. 4) Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
