MDA Series

3-Channel DSP Power Amplifier(3 x 700W@4/8Ω)
MDA3-700M is highly flexible and intelligent digital audio 3 Channels Class D power amplifier delivering up to a total of 2.1kW@4/8Ω or able to rive 70v/100v Constant Voltage Lines, in Direct Drive, without using internal transformers. To guarantee maximum reliability, for the 3 powered channels, the MDA3-700M includes one MARAN I SMPS and 3 highly efficient Class D Power Stages, each one working in BTL (Bridge Mode). The 3 output stages are very low noise and low distortion with efficiency up to 90% @ full load and also equipped with a full set of circuit protections. Designed to meet the most demanding residential application sound systems, it provides a basic set of features such as a matrix mixing mode where inputs may be routed/mixed in any ratio to any output.

The MDA3-700M includes a set of sophisticated processes for loudspeaker, implemented by the powerful MARANI® DSP running 48kHz/24bit [96 bits precision for the internal intermediate processes] and high performance 24bit AD/DA Converters. Processes as Noise Gate, dB/Oct IIR Hp/Lp filters for X-Over, parametric EQs per input and output sections, RMS compressor, alignment delay and Notch, Variable Q Hi/Lo Shelving and Hi/Lo Pass filters are available, all in all everything needed to optimize powered loudspeaker.

Moreover, a Overflow/Limiter function per channel provides internal processes monitoring to prevent Overflow Clipping to occur, in order to avoid feeding Class D amps with clipped waves and finally, jointly with a powerful embedded Clip Limiter, to avoid speaker damage with gain reduction at clip threshold. In addition, efficient heat dissipation system and Over-Heat protection are implemented, which themselves ensure reliability without compromises.

Furthermore the MDA3-700M is also equipped with a Dynamic Loudness function and an useful Pink/White noise generator. All setup parameters for input/output processes, DSP features are accessible by using the remote PC software.
