PDA Series

PDA330I is designed  to  meet  different applications, it provides 3 channels with output power of  300W@4Ω (Sub) or 2 x 300W@4Ω (Statellites).  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 Class D amplifier 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 MARANI® 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. Morever 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.
