FIR Amplifiers Module

2-Channel Power Amplifier(300W@4Ω+50W@8Ω)
PDA350IF is a complete solution dedicated to 2-way selfpowered loudspeakers. Designed to meet different applications, it provides 2 channels, composed of one way for powering the Woofer (Low Freq.) and one for powering Tweeter (High Freq.) , with output power of 300W@4 Ohm+50W(CH2)@8 Ohm. In addition it offers a full set of added value features such as on board DSP and RS485 connection from the DSP board for monitoring and control via dedicated PC software. To guarantee maximum reliability, the PDA350IF includes a highly efficient integrated power supply. The Woofer output stage uses the Class D Amplifier Module, the Tweeter stage is powered by a Linear 50W Amp.

The PDA350IF includes a set of sophisticated processes for loudspeaker, implemented by the powerful MARANI® DSP running 48kHz/24bit [96 bits precision for theinternal intermediate processes] and high performance 24bit AD/DA Converters. Processes as Noise Gate, up to 512 taps FIR filters OR up to 48dB/Oct IIR Hp/Lp filters for X-OVer, parametric EQs per input and output sections, RMS compressor, alignment delay are available, all in all everything needed to optimize a self-powered loudspeaker. FIR coefficients generated from the Third Party Applications can be imported as .txt file. Moreover the Peak 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 a reliability without compromises.

Furthermore the PDA350IF is also equipped with a Dynamic Loudness function and 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. A Powerful 512 taps FIR is available for the System Phase Correction, based on System Response measurement.
