JL Audio XD600/1v2 オーナーマニュアル

11

There is a single multi-color LED on the top 

surface of the amplifier to indicate the amplifier’s 
operating status.

 

1)    Flashing Green: The amplifier is powering up, 

audio output is muted. 

2)  Constant Green: The 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. 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.

The only condition that will shut down an 
undamaged XD600/1v2 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).

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.
