DPA440A is a High End 4-IN/4-OUT digital speaker management system which maintains the same high quality hardware present. Designed for maximum versatility, it provides all the processing and control necessary for both live and fixed installation use. Proving for any crossover configuration, it offers 4 analog inputs, 4 analog outputs, managed by a powerful MARANI® DSP Engine, for a full 96kHz processing, in addition to high performance 24 bit AD/DA Converters. Each input channel provides a choice of EQ with 13-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 to48dB/Octave. Each output path also features Peak Limiter, RMS Compressor and configurable Delay.

The DPA440A supports two full matrix mixing mode where on the first matrix each input may be routed/mixed in any ratio to any output and on the second matrix each output channel may be routed/mixed in any ratio to any output. For remote configuration and control the DPA440A 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.

DPA4448QRT: It is a special version of DPA440A, where the remote control can be selected between the USB connection on the front panel or the TCP/IP one, located on the rear panel, replacing the RS485.
