Four Inputs and Eight Outputs coupled with a user interface so easy you won't even need the manual to set up your system, the Protea System II 4.24C Digital Crossover/System Processor has all the audio processing tools needed for precise crossover and sound control. Each input allows you to control gain, delay and six parametric, low or high shelf filters. In addition to setting crossover frequencies, each output may be assigned to any one or a combination of inputs, allows you to program four parametric, low or high shelf filters, delay for time delay adjustments, output gain, reverse polarity and a compressor/limiter for speaker protection. All this in a one rack space with XLR input and output connections. You may also program and control the 4.24C with Ashly's Protea System Software (WindowsTM 95, 98, 2000, XP and NT platforms), AMX NetLinx, MIDI or SIA-Smaart software. In all, the Protea 4.24C is a powerful tool for use in fixed installation and live sound applications.

Architect Specifications

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.
