Purple Audio MC77 Limiter

The Purple Audio MC77 Limiter recreates the audio circuitry of the revision E 1176, using modern components matched to the original. Introduced in 1997, Purple Audio started making the MC76, an 1176 type compressor based on the D & E version units. The MC77 builds upon this legacy, adding new features that were lacking from the original.

Thousands of units later, Purple Audio maintains high parts and build quality, using components designed to last decades. Features like a toroidal power transformer, the best interlocking switches on the market, and conductive plastic potentiometers ensure the MC77 is built for longevity.

  • Single Element Class A Output Amplifier
  • Transformer Balanced XLR Inputs and Outputs
