STATUS LED / PROTECTION CIRCUITRY
There is a single multi-color LED on the top
surface of the amplifier to indicate the amplifier’s
operating status.
1) Flashing Green: amplifier is powering up,
audio output is muted.
2) Constant Green: amplifier is on and
functioning normally, audio output is active.
3) Constant Red: lights to indicate that the
amplifier has exceeded its safe operating
temperature, putting the amplifier into a
self-protection mode, which reduces the
peak power output of the amplifier without
muting the audio. When its temperature returns
to a safe level, the red light will return to green
and the amplifier will return to full power
operating mode.
4) Constant Amber (Yellow): Indicates
that an over-current condition has occurred and
is accompanied by a muting of the amplifier’s
output. Because the muting behavior may be
very short in duration, it may manifest itself as
an audible, repetitive ticking or thumping noise
in the output. Over-current conditions can be
caused by a speaker impedance lower than the
optimum load impedance range for the amplifier
or a short-circuit in the speaker wiring. The
latter can result from a short circuit between the
positive and negative speaker wires or between
either speaker wire and the vehicle chassis.
The “Status LED” will remain amber for a few
seconds, even if the over-current condition is of a
very short duration.
5) LED off / Amplifier Shuts Off Unexpectedly
The only condition that will shut down
an undamaged XD1000/1v2 completely is if
battery voltage or remote turn-on voltage drops
below 10 volts. The “Status LED” will turn off.
when this occurs. The amplifier will turn back
on when voltage climbs back above 11 volts.
If this is happening in your system, have your
charging system and power wiring inspected.
For more information on troubleshooting this
amplifier, refer to Appendix D (pages 14, 15).
SERVICING YOUR JL AUDIO AMPLIFIER
If your amplifier fails or malfunctions, please
return it to your authorized JL Audio dealer so
that it may be sent in to JL Audio for service.
There are no user serviceable parts or fuses inside
the amplifier. The unique nature of the circuitry
in the JL Audio amplifiers requires specifically
trained service personnel. Do not attempt
to service the amplifier yourself or through
unauthorized repair facilities. This will not only
void the warranty, but may result in the creation
of more problems within the amplifier.
If you have any questions about the installation or
setup of the amplifier that have not been covered
in this manual, please contact your dealer or
technical support.
