High Level Input with Sensing Power On
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.
Variable HPF/LPF for front and rear
Variable 12 dB/Oct 50-
300Hz HPF (High-Pass Filter) and LPF (Low-Pass Filter) for front
and rear channels.
Subsonic Filter
Independent variable 12 dB/Oct 6-70Hz sub-
sonic HPF (High Pass Filter) for front and rear channels.
Bass Boost
Variable 0-10 dB 40Hz bass boost provides
additional bass response at lower frequencies (rear channels
only).

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.
