Universal Audio 1176LN

The original Universal Audio 1176LN designed by Bill Putnam 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.

Today, the 1176LN is new again. While it certainly would have been possible and much simpler to modernize and "improve" the 1176LN, every effort was made to remain faithful to Putnam's 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. Demand the original.

The 1176SA calibrates two mono 1176s for stereo operation. 1176-SA Stereo AdapterThe 1176SA was first offered for the original 1176, but has become increasingly difficult to find for use with either vintage or new 1176s. Due to customer demand for stereo operation, we carefully recreated the original adapter. The 1176SA is a small device (4.25" x2.5" x1.75") which rests behind the 1176s. The 1176SA sports a full metal enclosure for proper shielding, gold-plated connectors. A 2-year battery is included. The 1176SA is compatible with both new and vintage models.
