HELPFUL HINTS
1. No sound from Ch 2 or 4:
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:
Tr y switching the GND LIFT switch IN or OUT (depending on your use).
If the hum is not eliminated, then use a 600Ω line input transformer cutting the input
ground on the connectors (Pin 1). This isolates the input ground from the AC power ground.
5. Poor sound (poor bass):
The speaker systems are wired out of phase to each other. To correct, reverse the wires
on one speaker connector only and your bass response should improve.
6. Main AC breaker trips:
Each 120VAC DCM4000 amp will require two separate 20 amp circuit (240V: 25 amp)
to deliver its full sine wave power with a bench load.
