MDA2-140PAF(D)/MDA2-140PAF(T) is a highly flexible, powerful and intelligent 2-Channel power amplifier delivering up to a total of 2x140W @ 4ohms, or 1x280W to drive 70V/100V Constant Voltage Line in Direct Drive without using internal transformer. Designed to meet the most demanding portable and fixed installation sound systems, it provides a full set of value added features such as on board DSP, Wifi Connection, and optional extension of Dante , Ethernet and Bluetooth with aptX . MDA2-140PAF includes a highly efficient Switch Mode Power Supply, which provides power to the output stages. The 2 output stages use the 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. MDA2-140PAF is more than an amplifier, but also a capable and sophisticated loudspeaker processor with its powerful MARANI® DSP running 48 kHz / 24 bit [ 96 bits precision for the internal intermediate processes] and high performance 24bit AD/DA Converters. It offers 2 channels of slope up to 48dB/Oct IIR HP/LP crossover filters, RMS compressor, parametric Eqs , alignment delay and white/pink noise internal generator, everything needed to optimize a loudspeaker system. Moreover, MDA2-140PAF supports sleep mode by setting time in the PC SW.
