Problem Possible Cause
Possible Solution
9. Speaker pops when Source unit may be sending pop noise to Disconnect RCA inputs then turn source
unit is turned on or off amplifier
unit on and off:
If pop noise is gone try a different Source Unit.
Possible ground loop noise Check to make sure grounds are correct
so No ground loops can exist:
If a poor ground exists correct the grounding.
DC offset at amplifier output
Measure the amount of DC voltage
across the speaker connectors at the
output of the Amplifier:
If the DC offset voltage at the amplifier
output is greater then 70mV it will cause a
turn on sound. Change the amplifier.
10. Bass Boost Distorted Input gain set too high or remote sub level Check gain settings:
control is turned all the way up Readjust gain settings with remote sub
control at center position.
11. Amp runs hot Inadequate ventilation Make sure unit has proper ventilation:
Check load impedance against the
Load impedance is too low
specifications:
Connect the proper load impedance.
12. Amp won't shut off Remote on wire is staying high or at 12V
Measure voltage between Remote on
terminal and the power ground terminal:
If the voltage is high disconnect the
Source Unit and see if the amp shuts off.
If it does try a different source unit.
