SLEEK, POWERFUL, PACKED WITH VALUE
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.
General Features:
- 12-Decibel/Octave Filter With Variable High-, Low- And Band-Pass Filters
- Selectable Input Voltage: Low (200 Mv To 2-Volt Rms) To High (800 Mv To 8-Volt Rms)
- 3 Turn-On Options: +12-Volt Remote Wire, Signal Sensing Or Dc Offset
- Onboard Led Clipping Indicator Simplifies Level Setting
- Signal Routing Flexibility With Selectable Input Mode And Type
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.
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.
