when used with normal, full range systems, set this switch to “FULL”. If you wish the internal crossover to power a driver of specific frequency range , use the “LOWPASS” or “HIGHPASS” settings.

when the crossover selector switch is in “low pass” mode, this control sets the upper frequency limit for audio program sent to the speakers.

when the crossover selector switch is in “high pass” mode, this control sets the upper frequency limit for audio program sent to the speakers.

use this control to match the outputs of you head unit to the amplifier. Starting with your head unit set at about the 2 o’clock position, increase the amp level control until distortion begins to occur, and reduce slightly from this point.
