Preset 58
Preset #58 (High Volume Pre Recorded Music) is included in ToneMatch® Presets Version 3.0. For information about how to obtain it please see:
Preset 57 is optimized for low volume music. The low bass is boosted to better match the physics/psychoacoustics of our own auditory system.
Preset 58 is optimized for higher volume music. Some of the bass is boosted and some of the upper mids are reduced to have a more natural sound at these higher volumes.
