Troubleshooting Tips
Symptom Probable Cause
No output
Low or no remote turn-on
Fuse blown
Power wires not connected
Audio input not connected .
Speaker wires not connected
Speaker are blown
Audio cycles on and off
Thermal protection engages
when amplifier heat sink tem-
perature exceeds 50º C (22º F)
Loose or poor audio input
Loose power connections
Distorted output
Amplifier level sensitivity set
too high exceeding maximum
capability of amplifier
Impedance load to amplifier
too low
Shorted speaker wires
Speaker not connected to am-
plifier properly .
Internal crossover not set prop-
erly for speakers
Speakers are blown
Poor bass response
Speakers wired with wrong
polarity causing cancellation at
low frequencies .
