speaker outputs

The JX360/4's speaker outputs are designed to
accept 16 AWG - 8 AWG wire.
Each pair of the JX360/4's channels are
designed to deliver power into speaker loads equal
to or greater than 2 ohms per channel when using
a "stereo" configuration and speaker loads equal
to or greater than 4 ohms per bridged pair of
channels when using a "bridged" configuration.

Speaker loads below 2 ohms nominal per
channel are not recommended and will cause
the amplifier to enter a protection mode.
brIdgIng consIderatIons
Bridging is the practice of combining the
output of two amplifier channels to drive a single
load. When bridged, each channel produces
signals of equal magnitude, but opposite polarity.
The combined output of the two channels
provides twice the output voltage available from
a single channel. The JX360/4 has been designed
for bridging of its channel pairs without the need
for input inversion adaptors.
To bridge a pair of channels, use the
"Left +" and "Right –" speaker connectors only
(the "Left –" and "Right +" remain unused).
When bridged, each channel will deliver
optimum power into a 4 ohm load.

When a pair of JX360/4 channels are bridged,
they will deliver 180W x 1 into a 4 ohm load or
140W x 1 into an 8 ohm load. Operating a
pair of bridged channels into a load lower
than 4 ohms is not recommended and will
cause the amplifier to enter a protection mode.

Any bridged channel pair must be fed by both
Input Channels corresponding to it (Left and
Bridged
Right). Failure to do so will result in significant
audible distortion.
When a pair of the JX360/4's channels are
operating in bridged mode, the output will be in
mono (only one channel). This mono channel
can contain right channel only information,

left channel only information or the sum of
the information from both the right and left
channels. In order to achieve one of these options,
configure the inputs to that pair of channels in
one of these two ways:
1) Left Channel Only or Right Channel Only
Information: If you wish to send a left-only
or right-only signal to a pair of the JX360/4's
channels, use a "Y-Adaptor" to split the single
channel signal into both left and right RCA
inputs. This option is useful when using a
pair of the JX360/4's channels to drive left
channel speakers only and the other pair of
the JX360/4's channels to drive right channel
speakers only.
2) Left + Right Channel Information:
When bridged and fed by a stereo input, a pair
of the JX360/4's channels will automatically
combine the left and right channels into a
summed mono (left + right) channel. This
option is useful when using a pair of the
JX360/4's channels to drive a subwoofer system
or a summed mono center channel.

amplIFIer status IndIcator lIgHts &
protectIon cIrcuItrY
There are two status indicator lights on the
control panel of the amplifier.
1) "Power" (Green): lights to indicate that the
amplifier is turned on and operating normally.
Located at the far left of the control panel.
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 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 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.

servIcIng Your 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.
