The UA 610 Tube Preamp & EQ Plug-In Collection recreates the iconic sound of the original 610-A and its modern 610-B successor, legendary for their warm tube tone and musical overdrive characteristics. Originally developed by Universal Audio founder Bill Putnam Sr. in the early 1960s, the 610 preamps became synonymous with classic recordings from artists like the Beach Boys, Johnny Cash, Adele, and Cold War Kids. This plug-in collection captures the rich harmonic detail and natural compression that made these preamps essential tools in studios worldwide.

This carefully modeled plug-in offers authentic emulations of the entire 610 signal path, including tube amplifiers, transformers, and circuit nonlinearities, delivering a three-dimensional tube warmth and presence to vocals, guitars, bass, and more. Users can record in real time through the 610-A or 610-B models using Apollo interfaces or add saturation and coloration during mixing with any UAD-2 hardware. The 610-A model is inspired by the famed Wally Heider 'Green Board' that shaped legendary sounds, while the 610-B features selectable input impedance and expanded EQ options, providing a broad tonal palette from clean to clipped.

Leveraging UA's Unison technology, the plug-in integrates seamlessly with Apollo hardware to replicate the precise impedance, gain staging, and tonal characteristics of the original analog preamps. This enables musicians and producers to access the full range of the 610’s expressive qualities, from subtle warmth to rich tube saturation, without leaving their digital environment. Whether used to enhance individual tracks or to add vintage color and depth across a full mix, the UA 610 Tube Preamp & EQ Collection brings legendary analog tube character to modern production workflows.
