The UA 1176LN is a classic limiting amplifier featuring FET-Style Compressor with Class A Output & Custom Transformers — True to the Original.

The 1176LN Classic Limiting Amplifier is a modern reproduction, yet every effort was made to remain faithful to UA founder Bill Putnam Sr.’s visionary design and intentions.

The original UA 1176LN was a major breakthrough in limiter technology — the first true peak limiter with all transistor circuitry offering superior performance with a signature sound — and set the standard for all limiters to follow. The ultra-fast attack time and trademark sound have lured legendary artists and studio moguls alike to the 1176LN — Peter Frampton, Joe Satriani, Joe Chiccarelli, Vance Powell, and Mike Elizondo are just a few names on a list that’s continued to grow, for nearly 50 years.

Carefully trained staff hand-wire and test each unit until it meets our uncompromising standards. This Universal Audio Classic version of the 1176LN captures all the nuance of the original through obsessive attention to detail and delivers that trademark sound. Demand the original.
