JL Audio JX400/4D - JX Series 4-Channel Class D Full-Range Amplifier

The JL Audio JX Series of amplifiers are designed with a specific purpose; to deliver clean, rock-solid performance and reliability at an affordable price. The JL Audio JX400/4D is a four-channel, full-range audio amplifier utilizing Class D technology that can be operated with a wide variety of source units and system configurations. Unlike gimmicky price-conscious amplifiers, JL Audio employs specified oversized output transistors and rugged MOSFET power supplies to unsure proper current, thermal capacity and better overall performance. In addition, the JX400/4D includes flexible signal processing capabilities with a fully variable 12 dB/octave crossover filter, pass-through preamp outputs and high-level inputs.

Integration Flexibility

For those systems that do not offer a preamp level signal option, you can connect speaker level signals directly to the “Hi-Level Inputs” connector using the supplied connector and wire harness. Simply splice the appropriate left/right and positive/negative wires to the included harness and plug the harness into the “Hi-Level Inputs” connector on the amplifier. The JX monoblock will attenuate the high-level signal to make it compatible with its input stage. Alternatively, a traditional left/ right pair of RCA type jacks is used for preamp level (low-level) signals. This is the preferred connection method whenever available.

Selectable 12 dB / octave filter

The JX class D full-range amplifier features a defeatable 12 dB / octave filter, which can be configured as a low-pass or high-pass filter and offers continuously variable cutoff frequency selection from 50-200 Hz. This feature is designed to attenuate frequencies above or below its filter frequency, so that the system’s speakers do not reproduce any audible and often harmful frequencies. 80 Hz is a good starting point for system tuning, but its also advisable to match the crossover point with that of your subwoofer's low-pass filter - this ensures that your system is properly distributing the frequencies to the appropriate medium.
