What You'll Love:

EFFICIENT CLASS-D DESIGN

• 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.

CLEAN, POWERFUL, RELIABLE

• 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.

STUDIO-GRADE SIGNAL PROCESSING

• 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

• LED clipping indicators on the control panel let you quickly set each channel pair’s input sensitivity, without the need for additional test equipment.

EASY CONNECTIVITY

• With “input type” switches on the stereo channel sections, RD series amps can eliminate the need for Y-adapters when bridging stereo output channels.

AUDIO TECHNOLOGIES:

DIFFERENTIAL-BALANCED INPUTS

• Combating induced cable noise, this technology allows for the use of conventional RCA cables while delivering many of the benefits of a true balanced connection and accepting a wide range of input signal levels.

NEXD SWITCHING TECHNOLOGY

• Using enhanced pulse width modulation techniques, NexD technology achieves exceptional audio fidelity and efficiency while delivering high-power output from very compact amplifier designs.
