JL Audio RD800/6


Clean, Powerful, and Reliable

The look is amazing, and the performance backs it up. These ultracompact full-range RD series amplifiers from JL Audio are engineered to generate loads of power with exceptional efficiency and low distortion. The result: premium audio quality with significantly reduced current draw and heat. Small size, minimal heat and lots of power — Class-D amplifier design offers significant advantages. And the NexD™ switching technology adds even more, using enhanced pulse width modulation techniques to boost the amplifier’s bandwidth while minimizing distortion and improving efficiency.

Studio-Grade Signal Processing and Indicators

This RD series amplifier’s signal processing features include high- or low-pass 12-decibel/octave filters for each channel pair, with continuously variable frequency selection from 50–500 Hz. The 6-channel model offers triple high-pass filters or full 3-way crossover capability. LED clipping indicators on the control panel let you quickly set each channel pair’s input sensitivity, without the need for additional test equipment. With “input type” switches on the stereo channel sections, RD series amps can eliminate the need for Y-adapters when bridging stereo output channels.
