JL Audio - JX400/4D: 4 Ch. Class D Full-Range Amplifier, 400 W

4-Channel Class D Full-Range Amplifier, 100 W x 4 @ 2 Ω / 70 W x 4 @ 4 Ω - 14.4V

The JX400/4D employs a highly-efficient Class D design with a robust MOSFET power supply to deliver a strong 100 watts to each of its four channels into 2 ohms (14.4V, 1% THD).

Use the JX400/4D in combination with our JX500/1D or JX1000/1D monoblocks to build an amazing amplification system at a very affordable price. Or, use the JX400/4D by itself to power two satellites, plus a subwoofer.

The JX400/4D includes a defeatable 12 dB / octave filter for each channel bank, which can be configured as a low-pass or high-pass filter and offers continuously variable cutoff frequency selection from 50-200 Hz. Dedicated hi-level inputs are included, in addition to conventional low-level RCA inputs, making it easy to integrate with a variety of OEM and aftermarket head units.

Class D Circuitry - Full-Range

Summary:

Optimized, Class D amplifier circuitry delivers high efficiency without sacrificing full-range frequency fidelity.

Detailed Information:

The design of our full-range Class D amplifier circuitry places a high emphasis on damping of the driven load and full-range frequency control. Exceptional efficiency is also achieved, which allows the amplifier to be physically compact and also draws far less current from a vehicle’s electrical system during high-power operation.
