Ashly Audio is introducing two new speaker processors for live sound and fixed installation applications to its line of Protea DSP products at InfoComm in Orlando, Florida, June 17-19. The Protea 4.8SP four-input/eight-output and Protea 3.6SP three-input/six-output 1RU digital signal processors offer an extremely intuitive user interface, plus PC control software, and comprehensive DSP, including crossover, equalization, delay and limiter functions.
Gain, delay and six filters (each a choice of parametric, low or high-shelf) may be applied to every input, each of which employs 24-bit, 48 kHz delta-sigma A/D converters with 128x over sampling. Outputs may be assigned from one or a combination of inputs. Butterworth, Bessel and Linkwitz-Riley crossover filters with up to 48 dB/octave slopes are available on the outputs, along with four parametric, low or high-shelf filters plus compressor/limiters to control feedback problems. Time delay adjustments, output gain and polarity reverse may also be applied to the outputs, which include limiters for speaker protection.
