4-IN/8-OUT 24-BITDIGITAL Speaker Processor

Price includes 7% GST

Description



 The Protea System II 4.24C from Ashly is a four input, eight output digital crossover/system processor. In addition to setting crossover frequencies, each output may be assigned to any one or a combination of inputs, which allows the user to program four parametric filters, low or high shelf filters, delay for time delay adjustments, output gain, reverse polarity and a compressor/limiter for speaker protection.


 


A powerful tool for use in fixed installation and live sound applications, the unit utilizes state of the art DSP that includes 24-bit, 48kHz delta-sigma A/D converters with 128x over-sampling. D/A conversion utilizes 24-bit delta-sigma converters with 128x over-sampling. All inputs and outputs are precision balanced and RF protected using XLR connectors.


 


Aside from front panel control, the user can also program and control the 4.24C with Ashly's Protea System software (Windows 95, 98, 2000, XP and NT platforms,) AMX NetLinx, MIDI or SIA-Smaart software.
