AMPLIFIER STATUS INDICATOR LIGHTS &
PROTECTION CIRCUITRY
There are two status indicator lights on the
input i control end of the amplifier.
Outs Amplifier Status Cha
~ 0 0 Input
~ Power Protect ~
~II~
Remote Bass Port
1) "Power" (Green): 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 a short-circuit
or a dangerously low impedance connected
to the amplifier output(s). Connecting the
speaker outputs to an impedance lower than
2 ohms stereo (4 ohms bridged) will cause
this protection mode to activate.
When this
protection
mode is activated, the amplifier will
reduce
it maximum power output to protect its
circuitry, which will manifest itselfas increased
distortion.
When the problem is corrected, the
amplifier will
return to normal operation.
Advanced Rollback Thermal protection
Unlike conventional thermal protection
systems, which shut down an amplifier when it
overheats, this system protects the amplifier by
gradually reducing power
output ifthe amplifier's
safe operating temperature
is exceeded. The
amplifier will continue to operate and return
to normal power output once its temperature
returns to a normal range.

Low-Voltage protection:
If the vessel's supply voltage drops below 10
volts, the entire amplifier will shut itself off to
protect its internal circuitry.
The green "Power"
indicator will turn off when this occurs. The
amplifier will turn back on when voltage climbs
back above
10 volts. This may happen in a rapid
cycle when bass-heavy
program material causes
a weak charging system to dip below
10 volts
momentarily.
If this is happening in your system,
turn your audio system off and have your power
wiring,
ground connections and charging
system inspected.
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
IL 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.
