Protea System II 4.24C Digital Crossover/System Processor

Technical Notes & Specifications

Architects Specifications
Protea System II 4.24C
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. Each input and output

shall have individual mute capability. The programmable digital 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 connectors. 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 programming 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.
