DPA480P is a cost-effective 4-IN/8-OUT digital speaker management system. Designed to be catered for any crossover configuration, it provides the suitable processing and control necessary for both live and fixed installation use. It offers 4 analog inputs, 8 analog outputs, managed by a powerful MARANI®  DSP Engine, in addition to high performance 24 bit AD/DA Converters.

DSP Marani DPA480P

Each input channel provides a choice of EQ with 30-band Parametric EQ, Gain control, Noise Gate Function, RMS Compressor and configurable Delay. Each output offers up to 7-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, HP/LP Filters and driver alignment Delay.

DSP Marani DPA480P

The DPA480P supports a full matrix mixing mode where inputs may be routed/mixed in any ratio to any output. For remote configuration and control the DPA480P can be connected via USB or RS485 connections. The control remote PC software allows simultaneous control up to 32 units, setting all parameters and showing real time levels.
