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 sub- woofer will be in standby mode (LED on front of CVSUB50 will be red). When the subwoofer senses an audio signal, it will automati- cally 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.

The Phase Control deter- mines whether the sub- woofer’s piston-like action moves in and out in phase with the main speakers or opposite the main speakers. There is no correct or incor- rect setting. Proper phase adjustment depends on sev- eral variables, such as sub- woofer placement and lis- tener position. Adjust the Phase Switch ç to maxi- mize bass output at the listening position.

Remember, every system, room and listener is differ- ent. There are no right or wrong settings; this switch offers the added flexibility to

adjust your subwoofer for optimum performance for your specific listening condi- tions without having to move your speakers. If at some time in the future you hap- pen to rearrange your listen- ing room and move your speakers, you should experi- ment with the phase switch in both positions, and leave it in the position that maxi- mizes bass performance.
