Marani Pascal PDA540P 4-Channel Power Amplifier with DSP & IIR FILTERS (4X500 W@4Ω)

Sale price$999.99


PDA540P  it provides 4 channels with output power of 4x500W @4 Ohm. Moreover the low and mid channels can be bridged into a powerful configuration allowing power of 1kW@4/8ohm + 2x500W@4ohm in order to drive Subwoofers and satellites. In addition it offers a full set of added value features such as on board DSP and RS485 connection for monitoring and control via dedicated PC software.

The 4 output stages use the Class D module. The PDA540P  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, crossover filters, parametric EQs per input and output sections,RMS compressor, alignment delay, all in all everything needed to optimize a self-powered loudspeaker. Moreover the efficient heat dissipation system and Over-Heat protection ensure uncompromised reliability. Furthermore the PDA540P is also equipped with a useful Pink/White noise generator. All setup parameters for input mixing, DSP features and the limiter setting are accessible by using the remote PC software.
