JL Audio HD1200/1 Class D HD Monoblock Subwoofer Car Amplifier

The core technology of the HD amplifiers is called Single Cycle Control™ which tracks the audio signal, compares it to the real PWM waveform and then corrects it in each and every cycle (over 400,000 times per second). By doing this, a multitude of distortion-causing mechanisms are tightly controlled to enable pristine amplification. This exclusive core amplifier technology is mated to our regulated, intelligent power supply (R.I.P.S.), advanced thermal management systems and a full complement of studio-grade processing features that puts the HD amplifiers in a performance class all their own.

With frequency response that extends smoothly into treble range, the HD1200/1 will be used in many creative ways by adventurous users, but its primary mission in life is to drive subwoofers, so its feature set has been optimized for that purpose. It features a variable slope crossover, infrasonic filter, polarity reversal switch, remote level control port and preamp outputs.
