Solution
Check the remote turn on connection and the
voltage at the amplifier and source unit
Check all system fuses
Recheck all connections
Check for short circuits
Check speakers with another amplifier
Double check all filter controls; possibly some
filter overlaps in frequency; if so, please correct
the alignment.
Double check function of speakers and wiring of
speakers and correct.
Check for adequate ventilation
Check load impedance
Check speaker wiring for short to the vehicle
chassis
Reduce input sensitivity (turn „LEVEL" CCW)
Check supply voltage at power terminal.
Readjust amplifier input level (turn „LEVEL"
CCW)
Check speakers with another amplifier
Set ENS to reduce distortions to min.
Recheck speaker wiring
Subwoofer: check wiring; check adjustment of
phase shift control and correct.
Reroute amplifier input wiring
Install a noise filter
Readjust ENS setting
Check all ground connections
Install a noise filter on the source unit's power
cable
Install a coupling transformer in the signal path
to improve ground isolation for the signal path
(ground loop isolator)
Readjust ENS setting
