Two-Channel Class A/B Amplifier: The JL Audio JX360/2 is a
two-channel, full-range (20-20,000Hz) audio amplifier utilizing Class A/B
technology. The JX360/2 can be operated with a wide variety of source units
(aftermarket or factory) and system configurations (Mono or 2-channel).
MOSFET Switching Power Supply: The JL Audio JX series two-channel
amplifier employs a rugged MOSFET power supply for outstanding reliability and
(RMS) Power @ 14.4V
(RMS) Power @ 12.5V
High-Mass Heat Sink: A heavy extruded aluminum heat sink is designed
to keep the JL Audio JX series amplifier in a comfortable thermal range during
demanding operation. This high-mass, extruded heat sink removes heat from the
amplifier circuitry, extending high-power operation. This improves reliability
and reduces the frequency of thermally related shut-down event.
Protection Circuitry: The JX360/2's protection circuitry automatically
shuts the amplifier down if thermal limits are exceeded, a short-circuit is
detected in the speaker wiring, or if low supply voltage limits are reached.
Status Indicator Lights: There are two status indicator
lights on the right side of the amplifier.
- Power (Green): This LED lights green to indicate that
the amplifier is turned on and operating normally.
- Protect (Red): The Protection LED lights Red to
indicate the amplifier's protection circuitry has been activated to prevent
product failure due to thermal overload, a short-circuit, or a dangerously
low impedance connected to the amplifier's outputs.
Input Sensitivity: The two-channel amplifier's Input
Sensitivity Control is used to match your source unit's output voltage to the
input stage of the amplifier for maximum clean output.
- Low-Level Input Range: 200mV-4V (RMS)
- High-Level Input Range: 2V-10V (RMS)
Variable Crossover: The variable filter design employed in the JX
series amplifier's crossover section allows you to switch filter modes and
change filter frequencies. The JX360/2 offers the following crossover
adjustments along the amp's side-panel.
- Filter Mode: The amplifier allows you to select either
a Low Pass, High Pass or Full-Range operation.
- Variable Frequency: You can set the amplifier's Low
Pass or High Pass crossover from 50 to 200 Hz.
Power/Ground/Turn-On Terminals: The two-channel amplifier
features set-screw terminals for the power, ground, and remote turn-on
- Power and Ground: The JL Audio amplifier's set-screw
Power and Ground connections are designed to accept 4 to 2 AWG power wire. A
2.5mm hex-wrench is supplied for making connections.
- Remote Turn-On: The JL Audio JX series amplifier's set-screw
turn-on lead will accept 18 to 8 AWG wire. The same 2.5mm hex-wrench is
supplied for making connection.
Note: The Amplifier is not equipped with a fuse. An
external 50-amp AFS, AGU, or MAXI fuse (not included) must be installed on
the power wire. If a wiring kit is used which includes a fuse with a value
other than 50-amps, the original should be replaced with a 50-amp fuse
Speaker Output Terminals: The JX360/2 amplifier's four
set-screw speaker terminals will accept 16 to 8 AWG speaker wire. The
amplifier's speaker terminals can be wired in a stereo or bridged configuration.
A 2.5mm hex-wrench is supplied for making connections.
Preamp Inputs: The two-channel amplifier features one set of
stereo RCA input jacks. The amplifier features a dedicated Input Sensitivity
gain control for these inputs. These controls are designed to match the input
sensitivity of the JX360/2 to the specific signal source that is feeding it. The
amplifier's low-level input can be set between 200mV-4V RMS.
Speaker Level Inputs: The JL Audio JX360/2 also accepts speaker level
signals, including those from factory systems (without the need for a
line-output converter), via the supplied 10" speaker-level harness. The
amplifier's high-level input can be set between 2V-10V RMS.
Preamp Outputs: The JX360/2 incorporates a pass-through
preamp output sections, so that additional amplifiers can easily be connected to
the same signal(s) feeding the two-channel amplifier. These preamp output
signals are buffered to prevent noise and are always preamp level, regardless of
the level of signals feeding the amplifier's inputs.
