channel signal into both left and right RCA
inputs. This option is used when deploying a
pair of the XD200/2v2’s channels to drive left
channel speakers only and the other pair of the
XD200/2v2’s channels to drive right channel
speakers only.
2) Left + Right Channel Information: When
bridged and fed by a stereo input, the
XD200/2v2’s channels will automatically
combine the left a nd right channels into
a summed mono (left + right) channel.
This option is useful when using a bridged
XD200/2v2 to drive a subwoofer system
or a summed mono center channel.
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.
2 Channel Amplifier
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.
5) LED off / Amplifier Shuts Off Unexpectedly
The only condition that will shut down an
undamaged XD200/2v2 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.
