VRP User’s Manual
I
f you should experience a problem with the operation of your subwoofer, please check all of the
following before seeking service. Following is a simple troubleshooting guide to assist you.
1. Verify that the unit is plugged in, the power outlet is active, and is supplying
proper voltage.
2. Is unit receiving an input signal from your source?
3. Have all controls on subwoofer (volume, crossover, phase, etc.) been properly set?
4. If unit has been running at high levels for an extended period of time, one of the
protection circuits may be engaged.
• Is the built-in amplifier extremely hot to the touch?
• Is your power line voltage sagging, such as when there are other devices on the
same circuit drawing lots of power?
If the protection circuitry is active, the unit may cycle on and off until operating parameters
return to normal. Under more serious conditions, the unit may shut off completely. Normal
operation should return upon cooling, but you may be required to turn the power off and then
on again to reset the unit.
The following conditions r
equire service by a qualified technician:
1. The power cord has become damaged.
2. The unit does not appear to operate nor
mally or exhibits a marked
change in performance.
3. The unit has been exposed to water.
4. Some part of the cabinet or circuitry is physically damaged.
