Speaker Outputs - JL Audio JX360/2 Owner's Manual

speaker outputs

The JX360/2's speaker outputs are designed to
accept 16 AWG - 8 AWG wire.
Bridged
CH. 1 CH. 2
(L) (R)
JX360/2 is 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
when using a "bridged" configuration.

Speaker loads below 2 ohms nominal per
channel are not recommended and may cause
the amplifier to initiate 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 JX360/2 has been designed
for bridging of its channels 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, the amplifier will deliver
optimum power into a 4 ohm load.

When bridged, the JX360/2 will deliver 360W
x 1 into a 4 ohm load or 220W x 1 into an 8
ohm load. Operating a pair of bridged
channels into a load lower than 4 ohms is
not recommended.
! I m p o r ta n t !
Any bridged channel pair must be fed by both
Input Channels corresponding to it (Left and
Right). Failure to do so will result in significant
audible distortion.
When the JX360/2 is 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 the JX360/2, use a
"Y-Adaptor" to split the single channel signal
into both left and right RCA inputs. This
option is useful when using the JX360/2 to
drive left channel speakers only and another
JX360/2 to drive right channel speakers only.
2) Left + Right Channel Information:
When bridged and fed by a stereo input, the
JX360/2 will automatically combine the left
and right input channels into a summed mono
(left + right) channel. This option is useful
when using a the JX360/2 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.
