manual abstract


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 abil- ity 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 digi- tal crossover shall have a maximum in/out level of +20dBu. Frequency response shall be ±.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 acive balanced, 100 ohms. Inputs and outputs shall be balanced type on XLR con- nectors. A 2 X 20 backlit LCD display will show all parameter, function and utility information. LED indicators shall show signal level, clip, limit threshold and mute conditions. Full program- ming and control of the unit shall be from the front panel or via the front panel accessable 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. There shall also be a four level security lockout feature. The programmable digital crossover shall weigh 10 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 4.24C Digital Crossover/System Processor.
