Problem and turn the volume up | JL Audio XD200/2 instruction

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: Indicates 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. 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 affected channel(s). Because the muting behavior may be very short in duration, it may manifest itself as an audible, repetitive ticking 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. This functionality can be used to diagnose a short-circuit by only connecting one channel at a time. The “Status LED” will turn amber when you connect the channel that is experiencing

the problem and turn the volume up.

5)LED off / Amplifier Shuts Off Unexpectedly The only condition that will shut down

an undamaged XD200/2 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 not covered in this manual, please contact your dealer or technical support.
