JL Audio HD750/1 Features:

    There have been many attempts at creating well-behaved, full-range switching amplifier designs. As it stands today, there are several good technologies to choose from, but there is one that stands out above all others and it’s called Single Cycle Control. This revolutionary core technology was mated to the legendary R.I.P.S. power supply, advanced thermal management systems and a full complement of studio-grade processing features to put the all-new JL Audio HD amplifiers in a performance class all their own. Of course, being Class D switching amplifiers, you can expect low current draw and a very compact chassis (and you won’t be disappointed on either front). But, what makes the HD amplifiers really special only becomes clear when you listen to one.

  • JL Audio HD Series Monoblock Class D Amplifier
  • RMS Power Rating (11V-14.5V):
    • 4 ohms: 750 watts x 1 chan.
    • 3 ohms: 750 watts x 1 chan.
    • 2 ohms: 750 watts x 1 chan.
    • 1.5 ohms: 750 watts x 1 chan.
  • Max power output: 750 watts x 1 chan
  • LED power (green) and protect (red) indicators
  • Mono/Single channel operation
  • R.I.P.S. – Regulated, Intelligent Power Supply
    • “Regulated” means that the power supply adjusts its operation so as to maintain the amplifier’s rated power output and low distortion operation over a wide range of vehicle voltages (11V – 14.5V)
    • This contrasts with conventional, “unregulated” power supplies, which allow rail voltages to sag in direct proportion to drops in the supply voltage
    • The “Intelligent” portion of the R.I.P.S. System is a circuit that actually monitors output current to optimize the amplifier’s output power over a wide range of load impedances (1.5 ohm to 4 ohm per channel)
    • Bottom Line – Optimum power, at any impedance between 1.5 ohm and 4 ohm per channel, at any vehicle voltage between 11V and 14.5V
  • Single Cycle Control – high-fidelity, full-range class D is a reality
    • Tracking the audio signal, comparing it to the real PWM waveform and then correcting it in each and every cycle (over 400,000 times per second)
    • Heavy duty aluminum alloy heatsink for heat dissipation
    • In addition to the sonic benefits of Single Cycle Control Class D, the technology also results in outstanding efficiency
  • Input sensitivity:
    • Low level: 200mV-2V
    • High level: 800mV-8V
  • 1 Pair of Buffered preamp RCA outputs for daisy chaining the audio signal
  • Variable high-pass filter (50-500 Hz, 12 or 24 dB/octave)
  • Variable low-pass filter (50-500 Hz, 12 or 24 dB/octave)
  • Infrasonic filter (30 Hz, defeatable)
  • Output polarity switch – Yes
  • Frequency response: 6-8,000 Hz
  • Dimensions: 10-13/16″L x 8-1/4″W x 1-15/16″H
