The programmable digital crossover shall consist of four inputs and eight outputs with the ability to assign any output to any input. Each input channel shall include: a delay stage with a maximum delay of 682.5ms; a gain stage capable of +12dB boost and -40dB cut; six filter stages configurable to be a parametric filter with a frequency range of 19.7Hz to 21.9KHz, 1/24th octave step and a +15dB boost, -40dB cut, or a 6 or 12dB/ octave high or low shelf filter. Each output channel shall include: a routing stage allowing the user to assign the output to any or a combination of input(s); a high pass/ low pass crossover filter stage with selectable slopes of 12, 18, 24 and 48dB per octave
using Linkwitz-Riley, Bessel or Butterworth filter configurations; four filter stages configurable to be a parametric filter with a frequency range of 19.7Hz to 21.9KHz, 1/24th octave step and a +15dB boost, -40dB cut, or a 6 or 12dB/octave high or low shelf filter; a delay stage with a maximum delay of 21.33ms; a gain stage capable of +12dB boost and -40dB cut and the ability to invert the phase; a full function compressor/limiter with a threshold range of -20dBu to +20dBu.
