4 Troubleshooting
Problem: Power indicator does not turn on.
Procedure: Check that the unit is plugged into a functioning outlet. En-
sure that there is an audio signal present on the audio input indicated
by the green LED being lit. If the unit is powered up but in sleep mode
(due to no signal), the blue active LED will not be lit.
Problem: No output heard on speakers; Blue power indicator is lit.
Procedure: Check that physical level controls are not turned down.
Check that input and output connections are secure. Ensure signal pre-
sent LED is lit to denote a signal. If there is no signal detected check
signal source and that level controls are set high enough. If using Co-
braNet, ensure that it is properly configured and sending full-level au-
dio. Refer to section 3.3.
Problem: Amplifier overheats and/or shuts off.
Procedure: Review section 2.2.3 on proper cooling procedures. Check
the clip LEDs on the front or rear of the amplifier to see if the signal is
overdriving (the signal light flashes red frequently). Overdriving the am-
plifier for extended periods of time can cause a thermal shutdown.
Problem: Output sound is distorted or cracking.
Procedure: Check all cables for damage or loose connections and re-
duce the gain on the input signal at the mixer or preamp level. Replace
the cables and loudspeakers temporarily to see if this resolves the
problem. If problem still exists, contact your Authorized Dealer for ser-
vice.
