Troubleshoot
before seeking service for your amplifier or subwoofer, please re-check all systems. Following is a simple troubleshooting guide to assist you.
1. Verify that the unit is plugged in and power outlet used is active.
2. Is the power switch on?
3. Is the unit receiving an input signal from your source?
4. Have all controls (volume, crossover, phase, etc.) been properly set?
5. If the unit has been running at high levels, one of the protection circuits may be engaged. Has the amplifier overheated?
6. Has the power button been depressed on the remote?
7. Make sure binding posts are tightened.
8. Is the remote non-responsive? We recommend replacing the batteries in the remote.
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
