Webster, NY (March 16, 2006)–Ashly Audio has released two DSP option cards for its PE-Series amplifiers. Proteane DSP option cards use a SHARC 200 MHz, 32-bit, floating-point processor and operate from 48 to 96 kHz with a 24-bit AD/DA. The Proteane DSP-1 XLR version and Proteane DSP-2 Euroblock version offer both analog and digital (AES3) inputs and two additional processed output channels for driving two more amplifier channels.
Proteane DSP cards have an extensive DSP library including graphic, parametric, notch and shelving equalization filter types, Bessel, Butterworth and Linkwitz/Riley high- and low-pass crossover filters with slopes of up to 48 dB/octave and all pass filters for phase correction. Additional processing blocks include signal delay, compressor/limiter, gate, matrix mixer, signal generators (sinewave, white and pink noise) and metering.
