about +12V of current.
Poor ground connection, Check the connections.

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.
