The EX.BB 500 from Aphex is a 500 series module that features two of the company's processors, the Aural Exciter and Big Bottom. The mono module can be installed in the company's USB 500 Rack or any 500 series compatible rack. The processors can be used individually or together, and enable switches allow for processor bypass or for comparison listening.
Originally designed to help negate high frequency loss from the constant replaying of multi-track tape during studio sessions, the Aphex Aural Exciter still has relevance in today's non-destructive digital world by enhancing sound quality without recourse to equalization. The processor is able to "open up" a sound source, adding clarity and definition without changing level or adding distortion.
The Optical Big Bottom provides low-frequency punch, without the unwanted level boost that comes from increasing low-end EQ. Benefits are deeper, more resonant, detailed bass with tighter articulation, extending the low frequency spectrum for a richer, more percussive sound, even at very low volume levels. The processor features Tune, Drive and Mix controls, enabling users to dynamically enhance low frequencies.
Both the Aural Exciter and Big Bottom are "smart" circuits, analyzing the audio signal in real-time, in order to provide the optimal amount of processing for the given moment in the signal, regardless of signal or file type and quality. The module is suitable for use in many audio environments including recording studios, broadcast facilities, concert arenas, musicians' equipment racks, DJ systems, houses of worship, auditoriums, theaters and sports venues.
