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.

One of the 1176’s famous features are its push-button selectable ratios of 4:1 and 8:1 for compression, and 12:1 and 20:1 for limiting. 1176 at 4:1, to its most notable setting, the “All Buttons In” mode, where all the ratio buttons are depressed simultaneously. This allows the 1176 to make a sound unlike any other processor ever heard before. Distortion increases, along with a plateaued slope and a lag time in response to initial transients, creating an explosive sound on drum room mics, fuzzing-out bass or electric guitar sound, or squeezing a vocal to bring it front and center of your mix.
