The Elysia mpressor 500 packs the functionality and Class-A discrete goodness of its bigger rackmount brother into a single-slot 500 Series module. Going far beyond what a "normal" compressor is capable of, the mpressor 500 employs awesome features like negative ratios, extreme time constants, "Anti Log" for extreme pumping compression and the unique Gain Reduction Limiter control. Amazing for all things percussion and especially handy for the extreme enveloping of dance and electronic music, the mpressor 500 is also versatile enough to handle every-day compression duties on any sound source.
