The Retro Instruments 176 Limiting Amplifier has the largest feature set in any variable-mu design. Its design is based on a Bill Putnam classic, the UA 176.
The Retro 176 faithfully reproduces the sound of the 1960s original with new features for the modern recording studio. The Retro 176 provides one of the most desirable compression signatures in recording history.
