Trobleshooting
DOES NOT TURN ON OR BLUE LED DOESN’T LIGHT UP:
▪
The power cables aren’t connected correctly (ter12V, GND
and REM).
▪
The power cables have a poor connection. Check the connections.
▪
REM without signal. Check to see if the REM connection is receiving
about +12V of current.
▪
Poor ground connection, Check the connections.
NO AUDIO SIGNAL:
▪
Channel and or MAIN level control is at the lowest setting, increase
the setting.
▪
Channel MUTE button pressed, release the button by pressing it again.
▪
The signal cables from the channels or MAIN are disconnected.
Check the connections.
DISTORTED AUDIO SIGNAL:
▪
Distorted/saturated audio signal. Adjust the volume level of the
signal source. Decrease the gain control of the mixer input channels.
UNWANTED NOISE:
▪
All RCA and power cables should be checked beforehand for
irregularities and corrected if necessary.
▪
Use cables that suppress interference on the spark plugs.
▪
Route the incoming and outgoing RCA cables away from any other
cables since they are more sensitive to interference.
▪
Install a separate power source (+12V) for the sound system.
▪
Ground the console properly. Remove paint from the chassis at
the selected point, and connect the wire using a grounded terminal.
In order to prevent rust, insulate it with paint.
