The crossover is divided into two sections: The Low section for the bass loudspeaker or subwoofer (mono or stereo) and the Mid-Hi section for the top/main speakers.
The crossover frequencies for Low and Mid-Hi can be set individually from 50 Hz to 120 Hz in 6 positions.
The Low filter has a slope of 24 dB per octave. The slope of the MID-HI filter can be switched from 12 dB to 24 dB.
