    BB-48S is a High End 4-IN/8-OUT digital speaker management system adding an astonishing FIR filtering tool set. Designed for maximum versatility, it provides all the processing and control necessary for both live and fixed installation use. 4 analog inputs, 8 analog outputs and 2 AES/EBU inputs are managed by 2 powerful DSP Engines, for a full 96kHz processing, in addition to 24 Bit AD/DA Converters. Each input channel provides 13 PEQ, Gain control, Noise Gate, RMS Compressor, Internal White/Pink Noise Generator and configurable Delay. Each output offers up to 7 PEQ, in addition to the IIR crossover filters whose slopes from 6 up to 48dB/Octave. Each output path also features PEAK Limiter, RMS Compressor and configurable Delay. Particularly, the Output X-Over Filtering can be selected to be IIR HP/LP filters (Butterworth, Linkwitz-Railey, Bessel) or 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 Asymmetrical FIR is available for Phase Correction purposes. Being the phase correction FIR Asymmetrical, a powerful tool for adjusting/reducing the FIR latency is available, allowing therefore the BB-48S 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 BB-48S 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 BB-48S can be connected via USB/RS485/TCP-IP connections. The control remote PC software allows simultaneous control up to 32 units, setting all parameters and showing real time levels.
