Universal Audio 1176LN Classic Limiting Amplifier

Universal Audio 1176LN Classic Limiting Amplifier



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


The Universal Audio 1176 LN design is based upon the original Universal Audio 1176LN, designed by Bill Putnam, that was a major breakthrough in limiter technology, the first true peak limiter with all transistor circuitry offering superior performance and a signature sound.

Evolved from the popular Universal Audio 175 and 176 vacuum tube limiters, the 1176LN retained the proven qualities of these industry leaders, and set the standard for all limiters to follow.

While it certainly would have been possible and much simpler to modernize and “improve” the 1176LN, every effort was made to remain faithful to Putnams design and intentions. 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.
