JL Audio JD400/4

Compact and Versatile: Fits nearly anywhere: 9.50 x 7.50 x 2.10 in. (242 x 190 x 53 mm) Ultra-flexible outputs, capable of multiple configurations:4-Ch. Satellite Amp: power front and rear speakers with 75W x 43-Ch. System Amp: power front speakers with 75W x 2 and a sub with up to 200W2-Ch. High-Power Satellite Amp: power 2pr. of speakers with 200W x 22-Ch. High-Power Subwoofer Amp: drive two subwoofers with 200W x 2

NexD™ Switching Amplifier Technology: Our advanced high-speed switching technology delivers outstanding fidelity with very low noise and distortion. Exceptional efficiency results in reduced current draw and heat, permitting reliable high power output within a very small chassis. Full-bandwidth operation in all channels. (20 Hz - 20 kHz bandwidth)

Complete Signal Processing Sections: 12dB/octave high or low-pass filters for each channel pair, defeatable, with fully variable frequency selection from 50-500 Hz. Preamp outputs (buffered, pass-through type, from CH. 1&2)

Dual-Range, Differential-Balanced Inputs and Automatic Turn-On Capabilities: NO NOISE! Outstanding noise rejection prevents alternator whine and other noises. Accepts line-level or speaker level signals up to 8V RMS, including those from factory systems, without a line-output converter (LOC): just splice wires to a pair of RCA ends or RCA cables. Selectable Input Mode switch permits one pair of inputs to feed both pairs of output channels. Automatic turn-on option via Signal-Sensing or DC-Offset sensing

Integrated LED Clipping Indicators for Easy Setup: Simplifies input-sensitivity setting by providing accurate visual feedback of output clipping level.1) Disconnect one speaker output wire2) Play full-scale (0 dBfs) sine-wave through audio system, with head unit at 3/4 volume and tone controls set flat.3) Adjust input sensitivity until light turns on, then back off slightly. Separate, top-mounted LEDs report overall status and condition
