3-IN/6-OUT 24-BITDIGITAL Speaker Processor

Add To Wishlist



The Protea System II 3.24CL-d from Ashly is a 3 input, 6 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 4 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.


The Protea 3.24CL-d is a variant of the 3.24CL with the only difference being the adjustable input and output delay times. Since the unit provides longer delay times on the outputs, distribution of audio to different zones is possible.
