Power an entire system
The XD700/5 5-channel amp can power your vehicle's entire system, delivering 75 watts RMS to each of your front and rear speakers, while powering a sub with up to 300 watts. You can also switch to 3-channel mode, and power your front speakers with 200 watts each, while still driving the sub with 300 watts. High- and low-pass filters give you intimate control over the character of your sound.

"Differential-balanced" inputs keep the signals clear of outside noise, and allow you to connect this amp to just about any in-dash stereo, even a factory radio with no preamp outputs. An optional wired remote lets you tweak the level from your front seat.

Features

5-Channel Full-Range Amplifier: The JL Audio XD700/5 is a five-channel, class-D amplifier utilizing NexD ultra-high speed switching technology to deliver outstanding fidelity and efficiency. The XD700/5 can be operated with a wide variety of source units and system configuration.

Amplifier Rating: The JL Audio XD700/5 Class D amplifier is rated at 75 Watts RMS x 4-channels (front & rear) + 180 Watts x 1-channel (subwoofer) in 4-ohm at 20 to 20,000Hz with a signal-to-noise-ratio of 104 dB and a total harmonic distortion of 1% while receiving 14.4 Volts.

NexD Class D Technology: NexD is a state-of-the-art switching amplifier design that combines exceptional audio quality with excellent efficiency and less complexity. This results in an affordable compact amplification with exceptional audio quality and unsurpassed total efficiency.

Advanced Rollback Protection: The XD-Series amplifiers employ advanced thermal and low-impedance protection to virtually eliminate annoying amplifier shut-down events. Should any XD-Series amplifier ever overheat, its intelligent, unregulated power supply reacts by limiting available peak voltage until the amplifier returns to a safe temperature range. Likewise, if an impedance lower than optimal for the amplifier is present at the outputs, the XD amplifier will roll back peak voltage to protect itself without shutting down.

Differential-Balanced Inputs: The JL Audio amplifier features differential-balanced input architecture to effectively control noise and ensure compatibility with a wide variety of source units, including many OEM systems. Without resorting to line output converters, you can directly connect most OEM source units to the JL Audio amplifier without creating any noise or compatibility issues. Unlike conventional single-ended inputs, the differential-balanced design does not connect one side of the audio signal to chassis ground. This eliminates any voltage sensitivity between one input terminal and ground and greatly reduces the incidence of alternator whine in a typical car audio installation.

Note: You will need three speaker wire to RCA adaptors (136XDCLR2S, sold separately) to connect this amplifier to your headunit via speaker-level.

Protection Circuitry With Status Indicator Lights: There is a single multi-color LED on the top panel of the amplifier to indicate the amplifier's operating status.

  • Flashing Green: When the LED is flashing green, the amplifier is powering up and audio output is muted.
  • Constant Green: This LED lights green to indicate that the amplifier is turned on and operating normally.
  • Constant Red: This Red LED lights to indicate that the amplifier has exceeded its safe operating temperature, putting the amplifier into a self-protection mode, which reduces the power output of the amplifier. The red light will shut off and the amplifier will return to normal, full-power operating mode if the heat sink temperature drops back to a safe level.
  • Constant Amber (Yellow): The Amber (Yellow) LED light indicates that an over-current condition has occurred and is accompanied by a muting of the amplifier's output. Over-current condition 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.
  • LED Off: The only condition that will shut down an undamaged XD700/5 completely is if battery voltage or remote turn-on voltage drops below 10-volts. The amplifier will turn back on when voltage climbs back above 11-volts.

Cooling System: The outer shell of the JL Audio amplifier is designed to remove heat from the amplifier circuitry. For optimum cooling performance, this outer shell should be exposed to as large a volume of air as possible.  Enclosing the amplifier in a small, poorly ventilated chamber can lead to excessive heat build-up and degraded performance.

Controls

Control Panel Cover: The XD700/5 features a Control Panel Security Cover which protects and hides the amplifier's controls. When installed, the cover ensures that the amplifier's settings are not accidentally changed while creating a clean aesthetic look for the amplifier and your installation. The control panel security cover is pre-installed at the factory and must be temporarily removed for access the amplifier's controls. The security cover is secured by two 2.5mm hex-head screws.

Simplified Gain Setting: The XD Series amplifier makes setting the gain level of the amp via the input sensitivity control very simple. All you need is Digital AC Voltmeter (142TK12V, sold separately) and a Test CD Disc (503CD104, sold separately) with a sine-wave test-tone recorded at 0 dB reference level in the frequency range to be amplified for that set of channels (50 Hz for subwoofer channels, 1 kHz for a midrange application).

Note: The XD700/5 is equipped with a independent gain controls for the 1/2, 3/4, & 5 channels.

Flexible Input Section And Active Crossover Network: The JL Audio XD amplifier provides a flexible input section and a comprehensive crossover network to fine tune your system effectively and accurately. The variable filter design employed in the JL Audio XD amplifier crossover sections allow you to seamlessly switch slopes, easily change filter frequencies and address what frequencies the preamp inputs will pass. The XD700/5 offers the following independent crossover adjustments for the front, rear, and subwoofer channels along the unit's top panel, behind a removal cover plate.

  • Input Mode: This switch allows operation of all 5 amplifier channels with only one pair of input signals (2ch); with independent front & rear input signal pairs (4ch); or with discrete front, rear, & subwoofer signal pairs (5ch).
  • Filter Mode: The amplifier allows you to select either a Full-Range or High-Pass crossover setting for channels 1/2 (front). For channels 3/4 (rear), you can choose between a Full-Range, High-Pass, or Band-Pass crossover setting. Either a Full-Range, a 12dB/oct. Low-Pass, or a 24dB/oct. Low-Pass crossover setting can bet chosen for the subwoofer channel (5).
  • Variable Frequency: For channels 1/2 (front), you can set the high-pass crossover frequency between 50-5,000 Hz. For channels 3/4 (rear), you can set the band-pass or high-pass crossover frequency between 50-500Hz. For channel 5 (subwoofer), you can set the low-pass filter frequency between 50-500Hz.

Connections

Power/Ground/Turn-On Terminals: The amplifier features set-screw terminals for the power, ground, and remote turn-on connections.

  • Power and Ground: The JL Audio amplifier's set-screw Power and Ground connections are designed to accept 8 to 4 AWG power wire. A 2.5mm hex-wrench is supplied for making connections.
  • Remote Turn-On: The JL Audio XD 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 60-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 60-amps, the original should be replaced with a 60-amp fuse

Speaker Output Terminals: The XD700/5 amplifier's twelve set-screw speaker terminals will accept 16 to 8 AWG speaker wire. A 2.5mm hex-wrench is supplied for making connections.

Preamp Inputs: The amplifier features 3 pair of differential-balanced RCA jack inputs. The amplifier features a dedicated Input Sensitivity gain control for the front 1/2, 3/4, and 5 channels of the amplifier. These controls are designed to match the input sensitivity of the HD700/5 to the specific signal source that is feeding it. The amplifier's input level can be set independently for all channels between 100mV-4V.

Remote Level Control: The amplifier features a standard telephone connector for adding an optional wired remote level control. With the addition of the optional wired Remote Level Control (136HDRLC, sold separately), you can control the volume of all channels or just the subwoofer channel of the XD700/5 from the front of your vehicle. This is useful for subwoofer level control or even as a master volume control for your system. If desired, multiple XD amplifiers can be controlled from a single HD-RLC controller using a simple phone line splitter and multiple phone cables (all sold separately).

Note: All inputs and outputs are located on one side of the amplifier to make installation of the amplifier simple and neat.
