SCS150SI/SCS160SI/SCS180.6SSCS150SI/SCS160SI/SCS180.6S 3 Dolby*Pro Logic*(Non-Digital) Speaker Level Use this installation method for Dolby Pro Logic appli- cations (not Dolby Digital, DTSor other digital processing), where the receiver/processor does not have a subwoofer output, or a volume-controlled preamp (line-) level output: Connect your receiver or amplifiers front left and right speaker terminals to the left and right terminals on the subwoofer that are marked “High Level In.” Connect the left and right terminals on the subwoofer that are marked “High Level Out” to the cor- responding terminals on the back of your front left and right speakers. Connect your receiver or amplifiers center, left and right surround-speaker terminals to the corre- sponding terminals on the back of your center, left and right surround speakers.

IMPORTANT: Do not use the LFE input on the subwoofer with Dolby Pro Logic processors. Note: If your receiver or amplifier only has one subwoofer output jack, then you will need to use a Y-connector (not included). Plug the male end of the Y- connector into your receiver or amplifiers subwoofer output jack, and connect each of the two female ends to separate RCA-type patch cords. Finally, plug the RCA- type patch cords into the line- level inputs on the subwoofer. Connect each speaker to the corresponding speaker terminals on your receiver or amplifier. Make sure your receiver or processor is correctly configured to indicate that the subwoofer is “On.” Note for advanced users: If your receiver/processor has a built-in low-pass crossover filter for the subwoofer output, you may use the LFE input to bypass the subwoofers internal crossover. Use this installation method for Dolby Digital, DTS or other digital surround processors: Use the line-level input jack marked “LFE” for the Low- Frequency Effects channel. Connect this jack to the LFE output or subwoofer output on your receiver or amplifier. Connect each speaker to the corresponding speaker terminals on your receiver or amplifier. Make sure that you have configured your surround- sound processor for “Subwoofer On.” The front left, front right, center and rear speakers should all be set to “Small.” Dolby Digital or DTS (or Other Digital Surround Mode) Connection LINE LEVEL IN LFE INPUTLFE OUT L R SUBWOOFERRECEIVER + + + + + + + + + + Receiver Subwoofer Out Left Front Left Rear Right Front Right Rear Subwoofer R L R L Center Line- Level In Right Surround Right Front Left Surround Left Front Center SCS150SI/SCS160SI/SCS180.6SSCS150SI/SCS160SI/SCS180.6S 5 OPERATION MIN MAX Subwoofer Level MIN MAX Subwoofer Level Move the Master Power switch (marked “Power” ) to the “” (On) position to use the subwoofer. The subwoofer will automatically turn itself on or go into standby (sleep) mode when left in the standby mode (“Auto/On” switch in the “Auto” position). When your receiver or amplifier is off, or is not sending program material to the subwoofer, the subwoofer will be in standby mode. When the sub- woofer senses an audio signal, it will automatically turn itself on. If the subwoofer does not sense a signal after approximately twenty minutes, it will automatically go into standby mode. When the “Auto/On” switch is switched to the “On” position, the subwoofer will remain on, whether or not program material is playing. If you will be away from home for an extended period of time, or if the subwoofer will not be used, switch the Master Power switch to the Off position.

SCS150SI/SCS160SI/SCS180.6SSCS150SI/SCS160SI/SCS180.6S 6 If there is no sound from any of the speakers: Check that receiver/amplifier is on and a source is playing. Check that the powered subwoofer is plugged in, and itsPower switch is switched on to the “” position. Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. Review proper operation of your receiver/amplifier. If there is no sound coming from one speaker: Check the “Balance” control on your receiver/amplifier. Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. In Dolby Digital or DTS modes, make sure that the receiver/processor is configured so that the speaker in question is enabled. Turn off all electronics and switch the speaker in question with one of the other speakers that is working correctly. Turn everything back on, and determine whether the problem is in the same place, i.e., the speaker that was working previously now has no sound and the speaker that was not working now sounds fine; or whether it has moved, i.e., the speaker that was not working still has no sound and the speaker that was working is still fine. 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 the problem 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 the center speaker: Check all wires and connections between receiver/amplifier and speaker. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. 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 con- figured so that the center speaker is enabled. If the system plays at low volumes but shuts off as volume is increased: Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. 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 output: Make sure the connections to the left and right “Speaker Inputs” have the correct polarity (+ and ). Make sure the subwoofer is plugged into an active electrical outlet. Make sure the powered subwoofer is plugged in, and itsPower switch is switched on to the “” position. TROUBLESHOOTING In Dolby Digital or DTS modes, make sure your receiver/processor is configured so that the subwoofer and LFE output are enabled.

Use a Y-cable from a mono source if necessary to connect to both inputs. Do not connect to the single LFE input. 2) Turn on generator; adjust to 100mV, 50 Hz. 3) Plug in UUT; turn the power switch ON. LED should switch from Red to Green. Turn LEVEL control full clockwise (MAX) 4) LED should Green; 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 2.0V, 50 Hz. Turn LEVEL control full clockwise. 8) Green LED should light; 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 (instructions on exploded view drawing); detach + and - wire clips. 2) Check DC resistance of woofer; it should be 3.4 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.
