6 Channel Full-range Amplifier (800 W)

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 our NexD™ switching technology adds even more, using enhanced pulse width modulation techniques to boost the amplifier’s bandwidth while minimizing distortion and improving efficiency.

The 4-channel amp churns out 400 watts of total power — 100 watts from each channel into a 2-ohm load (14.4 volts, 1% THD). The 6-channel amp outputs 800 watts of total power with an additional pair of channels capable of 200 watts each into a 2-ohm load (14.4 volts, 1% THD). All RD channel pairs are bridgeable for maximum application flexibility.

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.
