Troubleshooting
This section provides basic Christie Vive Audio CDA2/CDA3 Professional Power Amplifiers troubleshooting
information.
Do not service the amplifier yourself. Contact a qualified service technician.
Problem Resolution
The amplifier power will not turn
on.
• Verify that the amplifier is receiving power. Plug the amplifier into the
AC mains. Connect the IEC line cord to the AC power inlet on the rear
panel of the amplifier.
• Verify that the circuit breaker for the mains circuit is open. Reset the
circuit breaker, then turn the amplifier power on again. If the AC mains
breaker continues to open, check the voltage and amperage (d) of the
circuit.
•
Verify that the circuit breaker has the correct voltage and amperage
(d). If required, have a qualified electrician replace the circuit breaker.
If the circuit breaker continues to open, send the amplifier to an
authorized service center for repair.
The amplifier power is on, but
there is no sound from the
loudspeakers.
•
Check the amplifier indicators:
• If the ACTIVE indicators are lit for each channel, verify that the
amplifier is receiving power. See The amplifier power will not turn
on. on page 13.
•
If the SIG (signal) indicators are lit or blinking, check the level of
the input signal source.
• If the TEMP (temperature) indicators are lit for either channel, the
amplifier has overheated and idled one or both channels. See The
amplifier is overheating. on page 14.
•
If the DC (direct current) indicators are lit for either channel, an
abnormal condition exists within the amplifier or the load it is
driving. If the channel does not reset and the DC indicators remain
lit, send the amplifier to an authorized service center for repair.
• Check the amplifier mode:
•
If the amplifier is in PARALLEL or BRIDGE mode and the input signal
is connected to CH B, connect the input signal is CH A. See Input
Connections on page 8.
•
If the amplifier is in BRIDGE mode and the output connections is
made to CH A or CH B, use the center BRIDGE output connector to
connect the loudspeaker. See Bridge Mode Connections on page
11.
•
Verify that the attenuators on the front panel are turned up. Turn the
attenuators up until you hear output from the loudspeakers.
•
Check all connections between the amplifier and loudspeakers. Make
sure that the twist lock connectors are fully-inserted and seated. The
connectors must be inserted and turned 1/4” clockwise until they lock
in position. If screw terminal connections are used at the loudspeaker
inputs, make sure the cables are attached and do not cause a short
between the poles of the loudspeaker inputs.
•
Inspect the loudspeaker cables and repair any shorts or breaks in the
cables, or replace the cables.
•
Inspect all loudspeaker cable connection terminations to make sure
