Troubleshooting
This section provides basic Christie Vive Audio CDA5/CDA7.5 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”.
•
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”.
• 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.
•
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 they are
complete and wired correctly. Verify the polarity of each connection.
There is output from one
channel, but not from the
other channel.
•
Verify that the attenuators are turned up for both channels.
• 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.
Check the amplifier indicators:
•
If the SIG (signal) indicators are lit or blinking for both channels, make sure the
channel’s input signal is present and at a sufficient level to drive the input.
• 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”.
•
If the DC (direct current) indicators are lit for either channel, an abnormal
