Marani – MDA4-750PS

MDA4-750PS is a highly flexible, powerful and intelligent 4-Channel power amplifier delivering up to a total of 4x750W @ 4 ohms and 4x870W @ 2 ohms, or able to drive 70V/100v Constant Voltage Lines

MDA4-750PS is a highly flexible, powerful and intelligent 4-Channel power amplifier delivering up to a total of 4x750W @ 4 ohms and 4x870W @ 2 ohms, or able to drive 70V/100v Constant Voltage Lines. The 4 output channels can be bridged into 2, and provide 1500W@8ohms power output. 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.

MDA4-750PS 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 bandwith 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.

MDA4-750PS is more than just an amplifier. It is also a capable and sophisticated loudspeaker processor, thanks to its powerful MARANIĀ® 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.
