JBL SYNTHESIS SDA-7200 Troubleshooting/Specifications
TROUBLESHOOTING
Incorrect connections, configuration or operation is sometimes mistaken for a product
malfunction. If problems occur, see this section for troubleshooting information. If a problem
persists, please contact your JBL Synthesis authorized dealer or installer.
No power: • If no front panel indicators are lit, check to make certain
that the AC power cord is firmly inserted into the AC Power
Socket.
The front panel Standby/
On Switch does not function:
• It is normal for the Standby/On switch to be inactive when a
trigger cable is connected or when the Audio Sense Switch
is in the left, or ON, position. To restore this switch to manual
operation remove the trigger cable and change the Audio
Sense Switch to the right, or OFF, position.
Power on, but no audio: • If all Channel Operation Indicators are red the amplifier may
have shut itself down to prevent overheating. Turn the unit
off for about five minutes and then restart. If this problem
persists check for proper ventilation and if added air flow
does not solve the problem consult your dealer or installer.
• Check the surround processor to make certain it is not in a
“Mute” mode.
Audio from some, but not all
channels:
• If all some channels, but not all, have audio output first
check to make certain that all audio input and speaker
connections are solid.
• If some channels operate and show a blue Channel
Operation Indicator, but one or more are red, first turn the
unit off with the Master Power Switch and then turn it on. If
one or more Channel Operation Indicators are still red try the
following:
1. Turn the unit off and then check the speaker wire
connections at both the amplifier and speaker side to
make certain that none of the conductor strands are
touching the chassis or another conductor channel.
2. Remove the wires at the speaker end of a channel with a
red indicator and see if it turns blue. This is an indication
that fault is likely in the speaker and not the amplifier.
• If none of these suggestions solves the problem, turn your
amplifier off and contact your dealer or installer.
