MDA Series

3-Channel DSP Power Amplifier(2 x150W@4Ω+ 350W@8Ω)
MDA3-100M is highly flexible and intelligent digital audio 3 Channels Class D power amplifier delivering up to a total of 600W@4/8Ω. To guarantee maximum reliability, for the 2 powered channels, the MDA3-100M includes one MARANI® SMPS and 3 highly efficient Class D Power Stages, 2 working in SL mode and one in BTL, for powering the Sub output. 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 MDA3-100M  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(Auto Compressor), alignment delay and Notch, Variable Q Hi/Lo Shelving and Hi/Lo Pass filters are availabl, 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 a reimplemented, which ensure  reliability without compromises. All setup parameters for input / output processes , DSP features are accessible by using remote PC software.
