TROUBLESHOOTING
> FOCAL SIGN DOES NOT LIGHT
1.
Measure the voltage at the amplifier power terminal.
It should be between 12.5 and 15 volts.
2.
Measure the voltage at the amplifier REM terminal.
It should be between 12 and 15 volts.
3.
If you are using BTL high level for automatic turn on, try connecting a REM wire.
4.
Check your power and ground connections to be correct po and - and they are clean and tight.
5.
Check battery connections.
6.
Check the fuse in the REM wire.
7.
Check 80 AMP fuse at battery.
8.
Check fuse inside amplifier.
The fuse is inside the right end cap beside the power terminals.
The recommended ATC fuse size is three 25 amp.
> FOCAL SIGN IS FLASHING
1.
Is the amp very hot?
Wait a few minutes for it to cool down.
You need to get more fresh cool air to the amplifier.
Do not cover the amplifier or mount it flush into a hole.
2.
If the amp is cold and the Focal sign is flashing, there is an internal fault. The amplifier must then be returned
for service.
> NO SOUND
1.
Is the Focal sign light off or flashing?
2.
Is the source radio on and is there a sound signal coming from the source radio?
3.
Use an ohm meter and measure the speaker wires for short circuit.
4.
Check connections for small “wire whisker” that may be shorting between amplifier terminals or speaker
terminals.
5.
Use an ohm meter and measure the speaker for short circuit.
6.
Double check your connections to the source radio.
7.
Are you using the correct source radio wires and are they plugged into the correct amplifier RCA?
8.
Double check your connections to the speakers and speaker crossovers.
9.
Check that all amplifier switches are in the correct positions for your speaker set up.
10.
Check that HP & LP frequencies are set correctly for your speakers.
11.
If little or no sound, make sure that you are NOT in BP (Band Pass) Mode, with the crossover points
overlapping or HP/LP frequency reversed.
> AMPLIFIER BLOWS FUSE WHEN YOU TURN IT ON
1.
Power and ground may be reversed.
Check + and - polarity at amplifier and at battery.
> SUBWOOFER REMOTE VOLUME CONTROL DOES NOT FUNCTION
1.
Check that Remote Volume Control wire is plugged into the amplifier securely.
