Low-frequency information for subwoofer only.High efficient power
Stiffly regulated PWM power supplies. MOSFET switches maintain
rated power over a wide range of battery voltages.
Adjustable from 20Hz to 250Hz with a slope of 24dB per octave.This
allows for the adjustment of the upper point of the frequency bandwidth
and the respective subwoofer.
Adjustable from 15Hz to 40Hz with a slope of 24dB per octave.This allows
for the attenuation of frequencies that are mostly inaudible and cause
unnecessary strain on the amplifier.
Protection against thermal, overload and short circuit conditions.
This amplifier come complete with a compact remote GAIN CONTROLLER
which can be conveniently mounted on or under the dashboard of your
car.
