4-Channel DSP Power Amplifier(4 x 2000 W@4Ω)


MDA4-2000PS is a highly flexible, powerful and intelligent 4-Channel power amplifier delivering up to a total of 4x1700W @ 4 ohms and 4x2320W @ 2 ohms, or able to drive 70V Constant Voltage Lines. Designed to meet the most demanding portable and fixed installation sound systems, it provides a full set of value added features such as high output power, efficient cooling system, on board DSP and USB/Ethernet for monitoring and control via PC software.

MDA4-2000PS includes a highly efficient Switch Mode Power Supply, which provides power to the output stages. The 4 output stages use the well-proven Class D module-full bandwidth PWM modulator obtaining ultra low distortion, high efficiency and also equipped with a full set of circuit protections. Furthermore the Clip/Limiter function provides output monitoring to prevent speaker damage with gentle gain reduction at clip threshold, in addition to the efficient heat dissipation system and Over-Heat protection which themselves ensure uncompromised reliability.

MDA4-2000PS is more than just an amplifier. It is also a capable and sophisticated loudspeaker processor, thanks to its powerful MARANI® DSP running 96 kHz / 24 bit [ 96 bits precision for the internal intermediate processes] and high performance 24bit AD/DA Converters. It offers 4 channels of slope up to 48dB/Oct IIR HP/LP crossover filters, or up to 512 taps FIR filters[FIR coefficients can be imported as .txt/.csv file from external application] , RMS compressor, parametric Eqs , alignment delay and white/pink noise internal generator, everything needed to optimize a loudspeaker system.

Moreover, MDA4-2000PS allows a 12dB headroom on processes overflow. User can also set the parameters, select input source, load presets, etc with the extraordinary touchscreen LCD in front panel. Apart from regular analog and digital source input, DANTE™ is also optional.
