The all-analogue dual-mono sonic maximizer that restores natural brilliance and clarity of 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, it 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. The unit features independent Lo Contour and Process controls, unbalanced 6.3mm inputs and outputs, and unbalanced RCA inputs and outputs.
