TROUBLESHOOTING
> FOCAL SIGN DOES NOT LIGHT
1.
Measure the voltage at the amplifier power terminal. It should be between 12 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 polarity (+ and -) and make sure they are tight.
5.
Check battery connections.
6.
Check the fuse in the REM wire.
7.
Check fuse at battery.
8.
Check fuse inside amplifier. (
CHECK DIAGNOSTIC AND PROTECTION LED PANEL
, Pg 2)
• The fuses are located inside the right end cap of the amplifier beside the power terminals. The
recommended fuse size is six 25 amp ATC.
> FOCAL SIGN LIGHT IS FLASHING
1.
Is the amp very hot? (
CHECK DIAGNOSTIC AND PROTECTION LED PANEL
, Pg 2)
• If yes:
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.
Possible Short Circuit (
CHECK DIAGNOSTIC AND PROTECTION LED PANEL
, Pg 2)
• Check connections for small “wire whiskers” that may be shorting between amplifier terminals or speaker
terminals.
• Disconnect the speaker wires from the amplifier and turn the amplifier on. Does the light go solid?
If yes:
Keeping the speaker wires disconnected from the amplifier, use an ohm meter to measure the speaker
wires for short circuit.
> NO SOUND AND THE FOCAL SIGN LIGHT IS SOLID
1.
Make sure the source radio is on and that there a sound signal coming from the source radio.
2.
Double check your connections to the source radio.
3.
Make sure you using the correct source radio wires and that they are plugged into the correct amplifier RCA.
4.
Double check your connections to the speakers and speaker crossovers.
5.
Check that all amplifier switches are in the correct positions for your speaker set up.
6.
Check that
HP
frequency is LOWER than
LP
frequency.
> 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.
2.
The Remote Volume Control will not function if the amp switch is
DIRECT
. The switch must be in
MASTER
.
> SUBHARMONIC SYNTHESIZER DOES NOT FUNCTION
1.
The remote level control must be plugged in.
2.
Increase the 45Hz level and the 30 Hz Level.
