Get Legendary FET Compression with Tone and Attitude, True to the Original

Upon its release in 1967, the 1176 Limiting Amplifier became an instant classic because of its unique lightning-fast attack and release times, musical Class A output stage, and its wide range of sounds, ranging from subtle, near-transparent compression, to all-out drive and distortion.

Universal Audio’s 1176LN Classic Limiting Amplifier is a handbuilt, faithful reproduction of Bill Putnam Sr.’s original visionary design — an iconic piece of audio history that had a hand behind classic recordings from Led Zeppelin, The Rolling Stones, Michael Jackson, and more.

 
 

Add Toneful, Colorful Compression

Billed as a “true peak limiter with all transistor circuitry and superior performance on all types of program material,” the 1176’s major selling point was its ultra-fast attack time — a mere 20 µS (.00002 seconds) at its fastest setting. But engineers soon found out that the 1176 also injected character, attitude, and vibe to anything run through its circuitry. Some even used the 1176 with the compression turned off, just for the distinctive tone it imparts. The unit’s amplifiers and transformers all by themselves give a desirable “hot” quality to anything passing through them.

 

Create with a Legend 

In 1999, when Bill Putnam, Jr. relaunched Universal Audio, a reproduction of the Blackface 1176LN was the company’s first product. Reissued in 2000, it was based on the circuit designs of the C, D, and E revs of the classic 1176. One of the most critical aspects of recreating the sound of the original hardware, was faithfully reproducing the original output transformer, complete with the additional windings that provided the feedback signal to the final line output amplifier circuit. Bill Putnam Jr. found extensive design notes that enabled him to recreate and improve his father’s original design.
