Trobleshooting
DOES NOT TURN ON OR BLUE LED DOESN'T LIGHT UP:
The power cables aren't connected correctly (terminals +12V, 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.
