Purple Audio MC77 is a mono FET compressor modeled after the vintage Urei 1176 E revision. The modern electronic components and superior design of the Purple MC77 make it a cut above the 1176.
It all started when Purple Audio released the MC76 years before UA had done their 1776 revision. Using modern components they recreated the original sound and vibe of the vintage 1176 E rev. A main component of the original 1176 and the MC76 was the Clarostat input attenuator. When this attenuator was no longer available in 2002, Purple had to find an alternative attenuator that would work. After a brief pause and a new part, the MC77 was born - along with other new features that the MC76 did not have. This is truly a revered limiter - many customers prefer it over an original 1176 E!
