SCS150SI/SCS160SI/SCS180.6S SPEAKER CONNECTIONS Connection Tips To use the binding-post speaker terminals on the subwoofer, unscrew the colored collar until the pass through hole in the center post is visible under the collar. Insert the bare end of the wire through this hole; then screw the collar down until the connection is tight. The hole in the center of each collar is intended for use with banana-type connectors.
SCS150SI/SCS160SI/SCS180.6S Dolby* Pro Logic* (Non-Digital) – Speaker Level Use this installation method for Dolby Pro Logic applications (not Dolby Digital, DTS® or 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 amplifier’s front left and right speaker terminals to the left and right terminals on the subwoofer that are marked “High Level In.
SCS150SI/SCS160SI/SCS180.6S Dolby Pro Logic (Non-Digital) – Line Level Use this installation method for Dolby Pro Logic applications (not Dolby Digital, DTS or other digital processing), where the receiver/processor is equipped with a subwoofer output, or a volume-controlled preamp (line-) level output: Use RCA-type patch cords to connect the line-level subwoofer outputs on your receiver or amplifier to the line-level inputs on the subwoofer.
SCS150SI/SCS160SI/SCS180.6S O P E R AT I O N 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 HIGH LEVEL + L – – R + is not sending program material to the subwoofer, the subwoofer will be in standby mode.
SCS150SI/SCS160SI/SCS180.6S TROUBLESHOOTING 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 its Power switch ¡ is switched on to the “•” position. • Check all wires and connections 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.

SCS150SI/SCS160SI/SCS180.6S Test Set Up and Procedure Equipment needed: • Function/signal generator/sweep generator • Integrated Amplifier • Multimeter • Speaker cables General Unit Function (UUT = Unit Under Test) 1) From the signal generator, connect one line level (RCA) cable to the Subwoofer Line Level Input jacks L/R on the UUT. 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.
