482i Sonic Maximizer

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.

"An extraordinary device. It is effective and unobtrusive giving better apparent highs and improving clarity ...its outstanding characteristic is its naturalness of sound ...had superb sound qualities."
". . . phenomenal separation of instruments . . . clarinets, oboes, bassoons, and other reeds are refreshingly distinct in tone. The same goes for French horns and trombones, or violins and violas."
