The UA 175B and 176 Tube Compressor Collection delivers the legendary sound of Bill Putnam Sr.'s iconic compressors, renowned for their rich tube-driven gain reduction and sonic character. These plug-ins faithfully emulate the original hardware units that shaped countless classic recordings, offering musicians and producers the ability to infuse their tracks with authentic vintage compression and warmth. Designed to enhance vocals, drums, guitars, and synths, these compressors add harmonic richness and dynamic control, making them essential tools in modern music production.

Introduced in the early 1960s, these compressors were pioneering designs that provided fast attack times and independent Attack and Release controls, features that revolutionized studio recording and mixing. The plug-in versions preserve the unique feedback compression circuit from the original units, delivering smooth compression at lower input levels and intense limiting when pushed harder. Users can shape dynamics precisely across a range of compression ratios while benefiting from parallel processing capabilities and headroom controls to achieve polished and dynamic mixes with ease.

Beyond compression, the UA 175B and 176 plug-ins serve as powerful tone-shaping devices, allowing producers to apply tube-driven saturation and warmth even without engaging compression. Their ability to add depth, definition, and energy to various sources makes them invaluable for enhancing room mics, drum busses, guitars, bass, and vocals. The authentic sound and flexible controls make these compressors a go-to choice for achieving professional-quality mixes that retain the character and vibe of vintage studio gear.
