crossover mode selector when used with normal, full range systems, set this switch to “FULL.” If you wish to use the internal crossover to power a driver of specific frequency range, use the “LOWPASS” or “HIGHPASS” settings.
input level control use this control to match the outputs of your 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.
low pass frequency control when the crossover selector switch is in “low pass” mode, this control sets the upper frequency limit for audio program sent to the speakers.
high pass frequency control when the crossover selector switch is in “high pass” mode, this control sets the lower frequency limit for audio program sent to the speakers.
