When Universal Audio founder Bill Putnam Sr. introduced the 610 Modular Amplifier preamp in 1958, it was a milestone in audio history. The 610 is famous among record producers for its harmonic detail, clipping characteristics, and ability to overdrive in a warm, musical fashion. The original 610 preamp was integral to countless legendary recordings — from the Beach Boys’ Pet Sounds to Johnny Cash’s landmark At Folsom Prison. Its modern variant, the 610-B, helped create new classics by Adele and Cold War Kids.

Now, Universal Audio has fully captured the 610’s revered tube character and tone with the UA 610 Tube Preamp & EQ Plug-In Collection. for the UAD Powered Plug-Ins platform and Apollo audio interfaces.

The 610 plug-in collection includes both the classic 610-A model and modern 610-B hardware, and represents the first comprehensive modeling of this hallowed preamp design — including its tube and transformer components and unique distortion characteristics.

For Apollo Twin and Apollo DUO/QUAD users, the 610 collection works in conjunction with UA’s new Unison™ technology, an exclusive analog/digital integration system that enables continuous, realtime, bi-directional control and interplay between Apollo’s physical hardware and UAD software mic preamp models. With Unison, the Apollo mic preamp’s analog impedance, gain stage sweet spots, and component-level circuit behaviors are adjusted in real time to accurately emulate the target mic preamp model.

Available for purchase via UA's Online Store for $299*, the UA 610 Tube Preamp & EQ Collection is part of new UAD Software v7.5, which also includes the Brainworx-developed Dangerous BAX EQ Plug-In Collection and additional updates to the UAD-2 platform.

Universal Audio’s API Vision Channel Strip Plug-In is now also Unison-enabled via a free firmware update in UAD Software v7.5, allowing Apollo users to capture the authentic circuit behaviors of the Vision’s timeless 212L preamp.

*Owners of the UA 610-B Tube Preamp Plug-In can upgrade to the full 610 Tube Preamp & EQ Collection for $149.
