PSW-D112/DPS-12 CONTROLS AND THEIR FUNCTION
1. Power LED - Will illuminate when the unit is turned on with the main power switch. This light will be RED when the unit is plugged in and not receiving a signal; when the PSW-D112 receives a signal, the light will cycle to GREEN. If no signal is received after 10 � 15 minutes the light will cycle back to RED (standby) until a signal is present again. 2. Main Power Switch - Main Power Switch to the PSW-D112/DPS-12; turn ON to energize the subwoofer. Under normal operation, Power Switch may be left ON to utilize the Auto ON/OFF feature. For extended periods of non-use, or vacations, it is recommended that the subwoofer's Power Switch be turned OFF. 3. Level Control - The subwoofer Level Control, (PSW-D112, located on the front panel, DPS-12, on the rear panel) adjusts the volume of the subwoofer relative to the rest of the system. 4. Video Contour - The subwoofer Video Contour Control, (PSW-D112, located on the front panel) optimizes the subwoofer's performance for movie listening. When the video-contour switch is �on� the subwoofer's performance is tailored to deliver the impact and excitement of today's movies. The green LED will illuminate when the video-contour switch is on. 5. Speaker In Jacks - Main Input connection to subwoofer when line level, subwoofer, or pre-amp output connectors are not available, or when a high pass filter (set at 150Hz) to main loudspeakers is desired through the Speaker Output Jacks. 6. Speak Out Jacks - Connected to main loudspeakers when the Speaker Input Jacks are used. 7. Phase Switch - Changes the subwoofer's output to be in phase or 180 degrees out of phase with the program material. 8. Line Input - Main Input connection to subwoofer (preferred). 9. Line Output - When using the Line-Level Input jacks, these are connected to an external power amplifier or receiver to power the main loudspeakers with a high pass filter if desired. 10. Direct In - If you will be connecting the PSW-D112 to a receiver/processor containing a Dolby Digital or DTS surround technology, use this single RCA connection. See the owner's manual for complete instructions. 11. Direct Out - (rev0 version only) This connection allows you to connect more than one PSW-D112 or DPS-12 together; connect this output jack to the Direct Input jack on the second subwoofer.
