BBE Sonic Maximizer 482i

The BBE 482i Sonic Maximizer is a dual-mono sonic maximizer, featuring independent lo contour and process controls, with a transparent volume/boost, and hard-wire bypass. The all-analog 482i Sonic Maximizer restores natural brilliance and clarity to an audio signal by the use of two integrated functions. First, it adjusts the phase relationships between the low, mid and high frequencies through adding progressively longer delay times to lower frequencies, creating a kind of mirror curve to neutralize the effect of loudspeaker phase distortion.

Second, the Sonic Maximizer augments higher and lower frequencies as loudspeakers tend to be less efficient in their extreme treble and bass ranges. The end result is a dynamic, program-driven restoration which reveals more of the natural texture and detail in the sound without causing fatigue that is often associated with exciter effects, psychoacoustic processors or excessive use of equalizers.
