Universal Audio Releases 175B & 176 Tube Compressor Collection

UAD Software v9.10 features an end-to-end emulation of the world’s first purpose-built studio compressors

SCOTTS VALLEY, CA • August 6th, 2019 — Universal Audio is proud to release UAD Software v9.10 featuring the 175B & 176 Tube Compressor Collection, a detailed plug-in emulation of UA founder, Bill Putnam Sr.’s iconic, ultra-rare tube limiters.

Introduced in the early 1960s, Universal Audio's 175B and 176 Tube Limiters were the first purpose-built studio compressors. Predecessors to the renowned 1176LN, the 175B and 176 are prized for their rich tube gain reduction character, fast attack, and sonic flexibility, making them enduringly popular for adding richness and detail to vocals, drums, guitars, and more.

With roughly only 1,000 units made, vintage 175B and 176s easily command well over $5,000 on the vintage market today, and have been used on thousands of seminal recordings — from the Rolling Stones, Led Zeppelin, and Van Halen to Aretha Franklin and Miles Davis. Now, users 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.

  • Painstaking emulation of the entire circuit path and control set of Bill Putnam Sr.’s rare and iconic 175B and 176 tube compressors
  • UA 175B features a fixed 12:1 Ratio, while 176 features four selectable Ratios: 2:1, 4:1, 8:1 and 12:1
  • Exclusive plug-in features include Sidechain Link, Dry/Wet Mix parallel processing, and Headroom for user-customizable operating level
  • Includes artist presets from Jacquire King, Carl Glanville, Joe Chiccarelli, and more
