Safe dynamic range. In HP mode internal processor provides HP crossover function based on Linkwitz-Riley 4th-order acoustical responce. This perfectly matches the proper MB SubWoofer model. Model MB 18.0 and MB 12.0 This switch configures internal processor to drive SubWoofer in Crossover mode based on LinkwitzRiley 4th-order acoustical responce at 100Hz or 80Hz. The choice of Crossover Frequency depends on which MB Full Range model is used in combination with MB 18.0 or MB 12.
> MB Loudspeakers are designed for audio applications. Full range audio program signal is expected to be used as input. Although time-shaped limiter systems are implemented, using high energy bandlimited signal, or exteme equalization (boost) on a full range signal may damage this equipment.
