DPA480 is a High End 4-IN/8-OUT digital speaker management system which maintains the same high quality hardware present in former DPA480 versions. Designed for maximum versatility, it provides all the processing and control necessary for both live and fixed installation use. Providing for any crossover configuration, it offers 4 analog inputs, 8 analog outputs and 2 digital S/PDIF inputs, managed by a powerful MARANI® DSP Engine, for a full 96kHz processing, in addition to 24 bit AD/DA Converters. Each input channel provides a choice of EQ with 30-band Parametric EQ, Gain control, Noise Gate, RMS Compressor, Internal White/ Pink Noise Generator,and configurable Delay.Each output offers up to 11-band of parametric equalization, in addition to the crossover filters which themselves provide slopes from 6dB/Octave up to 48dB/Octave. Each output path also features Peak Limiter, RMS Compressor and configurable Delay.
