features and specifications
crossover mode selectors when used with normal, full range systems, set these switches to “FULL.” If you wish to use the internal crossovers to power a driver of specific frequency range, use the “LOWPASS” or “HIGHPASS” settings.
input level controls use these controls 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 controls until distortion begins to occur, and reduce slightly from this point.
low pass frequency controls when one or both of the crossover selector switches is in “low pass” mode, one can set the upper frequency limit for audio program sent to the speakers.
high pass frequency controls when the one or both of crossover selector switch is in “high pass” mode, one can set the lower frequency limit for audio program sent to the speakers.
