Vintage unit in great condition.
Urei Universal Audio 1176LN Rev. F Limiting Amplifier

The Urei Universal Audio 1176LN Rev. F is an original vintage version of one of the most important dynamics processors in recording history. The 1176 combines extremely fast FET compression with transformer coupled analogue circuitry, giving it the punch, presence and unmistakable character that has made the design a studio standard for decades.

This particular unit is a Revision F 1176LN, representing a highly desirable period in the evolution of the original hardware. It is an exceptional processor for vocals, drums, bass, guitars and many other sources where fast dynamic control and distinctive analogue character are required.

Original Vintage 1176LN Rev. F

The 1176 design evolved through a number of revisions, each with its own circuit changes and sonic characteristics. Revision F belongs to the later classic Urei era and retains the essential FET gain reduction architecture that defines the 1176 sound.

For engineers looking for an original vintage 1176 rather than a modern recreation, a genuine Rev. F provides the circuitry, components and workflow associated with the classic hardware itself.

Legendary FET Compression

The 1176 was revolutionary for its speed. Its FET based gain reduction circuit provides exceptionally fast attack and release times, allowing the compressor to control transients in ways that many traditional compressor designs cannot.

At moderate settings, the 1176 can provide controlled and energetic dynamic reduction while bringing a source forward in the mix. Driven harder, it becomes an unmistakable creative effect, adding density, aggression and harmonic character.

Four Ratio Settings and All Buttons Mode

The classic front panel provides four selectable compression ratios of 4:1, 8:1, 12:1 and 20:1. This allows the 1176 to move from conventional compression through increasingly strong limiting.

The famous All Buttons mode can be achieved by engaging all four ratio buttons simultaneously. This changes the behaviour of the compression circuit and creates the aggressive, explosive character that has become one of the most celebrated 1176 techniques, particularly for drums and parallel processing.

A Studio Classic for Vocals

The 1176 is one of the most established vocal compressors in professional recording. Its fast response can control peaks while its analogue circuitry adds presence, density and energy, helping a vocal remain focused within a busy arrangement.

Depending on the gain staging and time constant settings, it can provide anything from relatively controlled peak reduction to a much more obvious compressed vocal sound.

Exceptional on Drums, Bass and Guitars

Drums are another classic application for the 1176. Snare, kick, room microphones and complete drum buses can benefit from its fast transient control and aggressive character. The famous All Buttons technique is particularly effective when creating explosive room microphone and parallel compression sounds.

Bass guitar can gain consistency and additional presence, while electric and acoustic guitars can be shaped with fast dynamic control without losing the energy of the performance.

Input and Output Driven Character

The 1176 does not use a conventional threshold control. Instead, compression is determined largely by how hard the signal is driven into the input stage. The Input and Output controls therefore become an important part of both the gain reduction and tonal character of the processor.

This interaction encourages engineers to treat the 1176 as an instrument rather than simply a utility compressor. Different combinations of input level, ratio, attack and release can dramatically change the behaviour and personality of the source.
