  • Direct connection (High Level Input) can be made with the speaker output of your car audio unit if it is not equipped with RCA line output.
  • High Level Sensing power on feature allows the unit to be activated without the need for remote connection.
  • Independent variable 12 dB/Oct 50-300Hz HPF (High-Pass Filter) and LPF (Low-Pass Filter) for front and rear channels.
  • Independent variable 6-70Hz sub-sonic HPF (High Pass Filter) 12 dB/Oct for both front and rear channels.
  • Independent variable 0-10 dB 40Hz bass boost provides additional bass response at lower frequencies for both front and rear channels.

Footnotes

  1. CEA-2006 Compliant — Standardized “Voluntary” Testing & Measurement Methods for Mobile Audio Amplifiers. This standard advocates a uniform method for determining an amplifier’s RMS power and signal-to-noise ratio. Using 14.4 volts, RMS watts are measured into a 4-ohm impedance load at 1 percent Total Harmonic Distortion (THD) plus noise, at a frequency range (for general purpose amplifiers) of 20 Hz to 20,000 Hz.
