The Bill Putnam-designed tube limiter that changed recording. The 175B and 176 tube compressors are prized for their rich tube gain reduction character, fast attack, and sonic flexibility.
With only roughly 1,000 units made, vintage 175B and 176s easily command well over $5,000 on the vintage market today, and they can be found in the racks of some of the world’s finest studios. Now, you can track and mix with the only authentic plug-in emulation of the original UA 175B and 176 compressors — exclusively for UAD hardware and UA Audio Interfaces.
Introduced in the early 1960s, Universal Audio’s 175B and 176 compressors were the first audio compressors purpose-built for studio recording and mixing music. Often cited among the crowning achievements of audio pioneer and UA founder Bill Putnam Sr., the 175B and 176 are prized for their rich tube gain reduction character, fast attack, and sonic flexibility.
With its breakthrough fast attack time and independently variable Attack and Release controls, the UA 175B and 176 went far beyond all previously available broadcast limiters. They were quickly installed in the early 1960’s at both United/Western and legendary Sunset Sound studios, where a rack of 176s still reside today.
As an all-tube predecessor to the famed 1176, the 175B and 176 compressors have lent warmth and character to thousands of seminal recordings — from the Rolling Stones and Elton John, to Led Zeppelin, Van Halen, Aretha Franklin, and Miles Davis.
