Thermal protection engages when amplifier heat
sink temperature exceeds 75º C (167º F)
Loose or poor audio input
Loose power connections
Distorted output
Amplifier level sensitivity set too high exceeding
maximum capability of amplifier , resulting in
distorted sound

Action To Take
Check remote turn-on voltage at voltage amplifier and repair as needed.
Check power wire's integrity and check for speaker shorts. Fix as needed
and replace fuse.
Check power wire and ground connections and repair or replace as needed.
Check RCA connections and repair or replace as needed.
Check speaker wires and repair or replace as needed.
Check that ESP status indicator is not indicating an active event. Check sys-

Make sure there is proper ventilation for amplifier and improve ventilation
as needed.
Check RCA connections and repair or replace as needed.
Check power wires and ground connections and repair or replace as needed.
Readjust gain. Refer to the Adjusting the Sound of the System section of this

Check speaker impedance load, if below 2Ω, rewire the speakers to achieve
higher impedance.
Check speaker wires and repair or replace as needed.
