JL Audio HD1200/1 Features:

  • JL Audio HD Series Monoblock Class D Amplifier
  • RMS Power Rating (11V-14.5V):
    • 4 ohms: 1200 watts x 1 chan.
    • 3 ohms: 1200 watts x 1 chan.
    • 2 ohms: 1200 watts x 1 chan.
    • 1.5 ohms: 1200 watts x 1 chan.
  • Max power output: 1200 watts x 1 chan.
  • Remote bass level input
  • 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″Lx 8-1/4″Wx 1-15/16″H
