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
- With a choice of 250-, 500-, or 1000-watt amplifier versions delivering clean power into a 2-ohm load (14.4 volts, 1% THD), the JD monoblocks offer versatile applications. Use a JD mono amplifier to drive a single subwoofer — or a pair to deliver stunning output from your subwoofer system.
PREMIUM-LEVEL SIGNAL PROCESSING
- For easy setup and interface with your speaker system, the JD series features a 12 dB/octave low-pass filter, with continuously variable frequency selection from 50–500 Hz and a variable bass boost EQ.
SPEAKER LEVEL OR RCA INPUTS
- Our versatile JD series design features dual-range, differential-balanced inputs capable of accepting line-level and speaker-level signals. The technology offers superior noise rejection and excellent compatibility with a wide range of input signal voltages.
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.
