Universal Audio 1176LN Classic Limiting Amplifier
The Universal Audio 1176LN Classic Limiting Amplifier, captures all the nuance of the original through obsessive attention to detail and delivers that trademark sound.
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. Accept no copies.
The optional Universal Audio 1176-SA Stereo Adapter calibrates two mono 1176s for stereo operation. The 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.

What We Think
The Universal Audio 1176LN Classic Limiting Amplifier is the undeniable epitome and daddy of aggressive compression. With it's very fast attack and release times and transformer saturation, you can absolutely use the 1176LN "incorrectly" to achieve stunning results that just sound so right. You've heard it compress many an acoustic guitar (Engineer Jim Scott regularly used his 1176's on Tom Petty's acoustic guitars - Wildflowers, anyone? - and speaking of Wildflowers, mix engineer Richard Dodd strapped a pair across the stereo bus for this masterpiece of an album), and you've heard it compress bass and drums for years and years now. And don't think for a minute that you've never heard it on vocals - The 1176LN was used on Roger Daltry's vocals on "Who Are You". It feels stupid to try and tell you why you need at least one 1176LN; probably just because it's simply a given. It's THE compressor to have if you can only have just one.

As with the LA-2A, this compressor has a history of showing itself on thousands of recordings over the years! While providing a sweetness and "up front" effect on just about every instrument and vocals, it has that legendary "all buttons" feature that is often copied by other manufacturers for a really aggressive sound! Get the real deal with the 1176LN! This compressor also works great in conjunction with the LA-2A for vocals!
