CVSUB50 SUBWOOFER OPERATION
Press the Master Power switch (marked �Power� å) in to the On position to use the subwoofer. The CVSUB50 subwoofer will automatically turn on or go into standby (sleep) mode as described below. When your receiver or amplifier is off, or is not sending program material to the subwoofer, the subwoofer will be in standby mode (LED on front of CVSUB50 will be red). When the subwoofer senses an audio signal, it will automatically turn on (LED will be green). If the subwoofer does not sense a signal after approximately 20 minutes, it will automatically go into standby mode. 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 å to the Off position by pressing it until it pops out.

The Phase Control determines whether the subwoofer�s piston-like action moves in and out in phase with the main speakers or opposite the main speakers. There is no correct or incorrect setting. Proper phase adjustment depends on several variables, such as subwoofer placement and listener position. Adjust the Phase Switch ç to maximize bass output at the listening position. Remember, every system, room and listener is different. There are no right or wrong settings; this switch offers the added flexibility to

adjust your subwoofer for optimum performance for your specific listening conditions without having to move your speakers. If at some time in the future you happen to rearrange your listening room and move your speakers, you should experiment with the phase switch in both positions, and leave it in the position that maximizes bass performance.
