There are two status indicator lights on the 

amplifier’s control panel. These are as follows: 
 
1)  “Power” (Green): Located at the far left of the 

amplifier’s control panel, this LED lights to 
indicate that the amplifier is turned on and 
operating normally.

 

2)   “Protect” (Red): Indicates that the amplifier 

protection circuitry has been activated 
to prevent product failure due to thermal 
overload, short-circuit or a dangerously 
low impedance connected to the amplifier 
outputs. Connecting the speaker output to 
an impedance lower than 2 ohms will cause 
this protection mode to activate. When this 
protection mode is activated, the amplifier will 
shut down to protect its circuitry. When the 
problem is corrected, the amplifier will return 
to normal operation and the “Protect” LED 
will shut off.

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.
