PDASP2SA2 is a complete solution dedicated to 2-way or 3-way self-powered  loudspeakers. Designed  to  meet  different applications, it provides 2.1 channels with output power of  1000W+500W+500W @4Ω.  In addition it offers a full set of value adding features such as on board DSP.  To guarantee maximum reliability,  the PDASP2SA2 includes  a highly efficient switch mode power supply with PFC (Power Factor Correction) which provides power to the 2.1 output channels. The output stages use the 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 PDASP2SA2 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 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. All setup parameters for input mixing, DSP features and the limiter setting are accessible by using the remote PC software.
