Channels A & B Crossover Frequencies
The variable crossover controls allow each filter to be easily adjusted and “dialed in”
to the desired crossover frequency. The frequency the knob is turned to is called the
“cutoff frequency.” This cutoff frequency occurs at –3dB and will cause a reduction
in power that the speaker “sees” at a rate of 12dB per octave. Channels A & B are
dedicated High-Pass filters and will only allow frequencies above the crossover point
to pass.

• Channel A & B crossover points are continuously adjustable between 80Hz to 460Hz
