Each output channel shall include: 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 (Off) and 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 682.54ms; 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. Each input and output shall have individual mute capability. The programmable digital distribution processor shall have a maximum in/out level of +20dBu. Frequency response shall be ±0.25dB 20Hz to 20kHz. Dynamic Range shall be greater than 110dB (20-20KHz, unweighted) and SMPTE intermodulation distortion or THD shall be less than 0.01% at 1KHz, +20dBu. Input impedance shall be 18K ohms active balanced. Output impedance shall be active balanced, 112 ohms. Inputs and outputs shall be balanced type on euroblock connectors. LED indicators shall show signal present, limiter threshold, clip and mute conditions. Full programming and control of the unit shall be from the front or rear panel accessible RS-232 serial port using Ashly Protea System Software, or via MIDI. There shall be 30 factory presets that may be overwritten by the user and stored. External recall of up to eight scenes via contact closure shall be accessible through a euroblock connector. There shall also be a four levels of password protected security lockout. The programmable digital crossover shall weigh 9.0 lbs net and mount in a standard 19” rack using 1 space (1.75” high). The power requirement shall be 80-260VAC, 50-60Hz, 30W. The unit shall be an Ashly Audio Protea System II 4.24D Digital Distribution Processor.
