LPP480F is a high end 4-IN/8-OUT digital speaker management system which is MARANI® flagship controller, adding astonishing hardware and software features on the basis of the LPP series. Designed for maximum versatility, it provides all the processing and control necessary for both live and fixed installation use. Proving for any crossover configuration, it offers 4 analog inputs, 8 analog outputs, 2 Stereo AES/EBU inputs, and 4 Dante™ inputs, managed by 3 powerful MARANI® DSP Engines, for a full 96kHz processing, in addition to 24 Bit Texas Instruments AD/DA Converters. Each input channel provides a choice of a 13-band Parametric EQ, with plenty of filter types, Gain control, Noise Gate, RMS Compressor, Internal White/Pink Noise Generator, and configurable Delay. Each output offers up to 7-band of parametric equalization, in addition to the IIR crossover filters which themselves provide slopes from 6dB/Octave up to 48dB/Octave. Each output path also features PEAK Limiter, RMS Compressor and configurable Delay. Output X-Over Filtering can be selected to be IIR style, with the complete set of Classic Hp/Lp filters (Butterworth, Linkwitz-Railey, Bessel) or FIR, being for each output channel available a 512 taps FIR filter which can be set as Hp/Lp/Bp.
On each one of the 4 Input paths, one more 1024 taps FIR is available for Phase Correction purposes, where the Coefficients Calculation can be supported by an embedded Wizard tool or can be loaded from external sources as Third Parties software for the FIR filters coefficients generation. Being the phase correction operated by an FIR Filter which can be Asymmetrical other than Symmetrical, a powerful tool for adjusting/reducing the FIR latency is available, allowing therefore the LPP480F to be used without any problem also for Live performances still having the Phase correction FIR running together with the eventual FIR for the X-Over implementation in cascade.
The LPP480F supports a full set of matrix mixing modes where Input sources can be routed/mixed to the Input paths, inputs paths may be routed/mixed in any ratio to any output and couple of outputs (1/2, 3/4, 5/6, 7/8) can be swapped at pleasure. For remote configuration and control the LPP480F can be connected via USB /TCP-IP Interfaces. Moreover, with front panel dedicated buttons, user can go directly to the editing pages like Xover, channel editing windows, while can monitor the real-time meters and other parameters from the LCD screen.
