HELPFUL HINTS

6) Note: Each amp will require a dedicated 20 amp circuit if
you are driving the amp to its full output.  There will be a sus-
tained loss of power if the AC voltage is below the rated 120V
or 230/240V input.

1) NO SOUND FROM CH 3:  The rear BRIDGE switch has been

inadvertently pushed in.

2) STEREO CHANNELS SOUND THE SAME:  The rear 

PARALLEL switch has been inadvertently pushed in.

3) NO HIGH FREQUENCIES:  Tweeters or midrange drivers have

been damaged or blown from feedback or overpowering.

4) SYSTEM HUM:  Try switching the GND LIFT switch IN or OUT
(depending on your use).  If hum is not eliminated, then install
Carvin’s MTF55 “Ground Lifter” between the amplifier input and
signal source.  This isolates the input ground from the AC power
ground. 

5) POOR SOUND (BASS): The speaker systems are wired out
of phase to each other.  To correct, reverse the wires on one
speaker connector only and your sound, especially bass response
will improve.
