PDA300I is a complete solution dedicated to 2-way self-powered loudspeakers. Designed  to  meet  different  applications, it provides 2 channels with output power of  300W @ 4ohm.  In addition it offers a full set of value adding features such as on board DSP.  To guarantee maximum reliability,  the PDA300I includes  a highly efficient switch mode power supply with PFC (Power Factor Correction) which provides power to the 2 output channels. The 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 PDA300I 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 Clip/Limiter function per channel provides output monitoring to prevent speaker damage with gentle gain reduction at clip threshold, in addition to the efficient heat dissipation system and  Over-Heat  protection  which  themselves  ensure uncompromised reliability.

Furthermore the PDA300I is also equipped with a Dynamic Boost Filter. All setup parameters for input mixing, DSP features and the limiter setting are accessible by using the remote PC software.
