The amplifier's input circuit filters out everything above 40....250 Hz, depending on the set-point of the frequency control, so that only the chosen bass notes / frequencies are amplified.

Input sensitivity control In order to achieve maximum signal-to-noise performance, the input sensitivity control adjusts the signal level from your car stereo/source, to match the amplifier's sensitivity. It is not a volume control. Note Not performing this adjustment and simply setting the input sensitivity control at or near the MAX position may permit electrical audio noise into the system. www.insignia-products.com 11
