input

 

fuse blown

 

power wires not connected

 

audio input not connected

 

or no output from source

 

speaker wires not connected

audio cycles on and off

speakers are blown

 

thermal protection engages

 

when amplifier heatsink

 

temperature exceeds 90° C

 

loose or poor audio input

distorted output

amplifier level sensitivity set too

 

high; exceeding maximum

 

output capability of amplifier

 

impedance load to amplifier too

 

low

 

shorted speaker wires

 

speaker not connected to

 

amplifier properly

 

internal crossover not set

 

properly for speaker

action to take

check remote turn-on voltage output at amplifier and correct as needed

check power wire integrity and reversed polarity, repair as needed and replace fuse

check power wire and ground connections and repair or replace as needed

check input connections and signal integrity, repair or replace as needed

check speaker wires and repair or replace as needed

check system with known working speaker and repair or replace speakers as needed

make sure there is proper ventilation for amplifier and improve ventilation as needed

check input connections and repair or replace as needed

reset gain referring to the tuning section of the manual for detailed instructions

check speaker impedance load if below 2 stereo or 4 mono rewire speakers to achieve a higher impedance

check speaker wire connections and repair or replace as needed

check speaker wiring and repair or replace as needed refer to the installation section of this manual for detailed instructions

reset crossovers referring to the multi-cross™ crossover configuration section of this manual
