MODULO DI AMPLIFICAZIONE MARANI PDA330I

PDA330I is designed to meet different applications, it provides 3 channels with output power of 300W@4 ohm (Sub) or 2 x 300W@4 ohm (Satellites). In addition it offers a full set of value adding features such as on board DSP. To guarantee maximum reliability, the PDA330I includes a highly efficient switch mode power supply with PFC (Power Factor Correction) which provides power to the 3 output channels. The woofer output stage uses the well-known ICEPower 300ASC+300AC Class D module - full bandwith PWM modulator obtaining ultra low distortion, high dynamic range and also equipped with a full set of circuit protections. The PDA330I includes a set of sophisticated processes for loudspeaker, implemented by the powerful M704 DSP running 96kHz/24bit [96 bits precision for the internal intermediate processes]. Processes as Noise Gate, crossover filters, parametric EQs per input and output sections, alignment delay, all in all everything needed to optimize a self-powered loudspeaker. Morover the RMS Compressor function per channel provides output monitoring to prevent speaker damage with gentle gain reduction at threshold, in addition to the efficient heat dissipation system and Over-Heat protection which themselves ensure uncompromised reliability. All setup parameters for input mixing, DSP features and the limiter setting are accessible by using the remote PC software.High Band can be splited or not in two sub-band. When the Xover split freq is enabled then the RMS compressor working on the lower band and a additional volume (hi_level) working on the Higher band.
