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
- Churning out 400 watts of total power — 100 watts from each of its 4 channels into a 2-ohm load (14.4 volts, 1% THD) — this JD series amp brings stunning output to your speaker system. It’s also fully bridgeable, so it can be used as a 3- or 2-channel amp to drive even more power through each line.
PREMIUM-LEVEL SIGNAL PROCESSING
- This JD 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.
LED CLIPPING INDICATOR RINGS
- An LED clipping indicator ring that surrounds each input level potentiometer lets you quickly and accurately set your amplifier’s input sensitivity, without the need for additional test equipment.
BUILT STRONG AND SMART
- Featuring a sleek industrial design with molded end caps and an aluminum extruded chassis, the JD series’ power indicator and protection LED indicators shine from behind a simple black logo bar on the top surface of the amplifier.
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.
