MDA44T is a 4-channel power amplifier in class D that offers flexibility, efficiency and is able to provide a total output power of 3200W @ 4 ohms. Designed to meet the most demanding requests for both live and fixed installations, it provides high-value features including an efficient cooling system, high output power, an integrated DSP processor and USB / Ethernet / M connections-LAN that allow remote monitoring and control via dedicated PC software. To ensure maximum reliability, MDA44T uses two highly efficient switching type power supplies that individually provide energy to a pair of output channels. The output stages use the Circuitazione in Class D, which allows to obtain high efficiency, low distortion, all equipped with a complete set of circuit protection, in addition to the efficient heat dissipation system and overheating protection which in turn They guarantee reliability without compromise. Furthermore, the clip / limiter function provides output monitoring to avoid damage to the speakers with a slight reduction in the clip threshold. MDA44T is much more than an amplifier. In fact it includes a powerful and sophisticated DSP processor at 48KHz 24 bits in addition to the excellent AD / from to 24bit converters. The processor section has 4 channels of crossover filters up to 48db / oct, parametric eq parametrics both input and outgoing, RMS compressor, Peak limiter, alignment delay and also each input includes an internal pink / white noise generator, the Everything needed to optimize a sound diffusion system. MDA44T supports "Routing" mode in which the inputs can be routed / mixed in any output. All the configuration parameters of DSP functions and limiter settings are accessible both using the front panel controls, which the deducted PC software.
