DriveCore Install DA Series Operation Manual

Troubleshooting

CONDITION: No input signal. The

Signal LED is not flashing, even

though audio is present and the

channel is ready.

POSSIBLE REASON:

• Input signal level is very low.

CONDITION: Bridge LED is lit.

POSSIBLE REASON:

• Amplifier is in bridge mono mode.

“Off/Flashing/On” above means that

the LED can be off, flashing, or on.
