Trouble Shooting Guide
1. No output: Disconnect any secondary speakers and check for operation of the primary speaker only. If still
there is no output, check for loose screws on the green input connector. It is easy to think the wires are secure
in the connector and one wire is not. Tug on each wire to make sure each is tight.
2. Intermittent output: Check for shorted output causing the amplifier to into and output protection. Check each
input wire for loose screws.
3. Distortion: Do not power more than one AMP04TRP on one power supply. While it will work, it will cause
distortion.
4. No output, check to see that the power on light is on. It is located on the main PCB. If it is off, the power
supply is either bad or has come loose in the power socket.
5. Hum, for single ended inputs, there is a need for a jumper between – and the ground screw. Most of the time,
the jumper is needed.
