TROUBLESHOOT
SUBWOOFER ISN’T PLAYING
1. Verify unit is plugged in and power outlet used is active.
2. Verify the power switch is on.
3. Verify the subwoofer is connected to a source and all 12V triggers are on.
4. Verify the subwoofer can produce sound. A good way to test this is to press 3-2-1 on the remote control
while pointing it at the IR sensor on the subwoofer. The woofer should play the sweep tone used for room
Self-EQ.
IF THE BASS DOESN’T SOUND LOUD ENOUGH TO YOU:
1. Increase the subwoofer’s VOLUME level.
2. Increase the receiver’s LFE or SUB OUT volume level, if it is adjustable.
3. Put the subwoofer closer to a corner of your room.
IF THE SUBWOOFER OUTPUT IS DISTORTED, INTERMITTENT OR STOPS:
The subwoofer may have shut down due to the protection circuitry.
1. Reduce the volume setting; or
2. Shut the subwoofer o until normal operating conditions return.
