Unison Enabled


Authentic tube mic preamp modeling – featuring Unison technology for Apollo interfaces.

When Universal Audio founder Bill Putnam Sr. introduced the 610 Modular Amplifier preamp in the early '60s, it was a milestone in audio recording history. The 610 became famous among record producers for its startling harmonic detail, and rich clipping characteristics, and its ability to overdrive in a warm, ultra-musical fashion.

The original 610-A preamp was integral to countless legendary recordings — from the Beach Boys’ Pet Sounds and Johnny Cash’s At Folsom Prison. Its modern variant, the 610-B, helped to create new classics by Adele and Cold War Kids. Today, you can add the same tube presence, warmth, and body to vocals, guitars, bass and more with the UA 610 Tube Preamp & EQ Plug-In Collection for UAD-2 and Apollo interfaces.

Give your tracks startling three-dimensional tube warmth, presence, and body

Record “through” the 610-A or 610-B tube preamp models in real time using Apollo Twin, DUO, or QUAD

Mix and saturate signals with any UAD-2 hardware for an iconic tube glow

Use the 610-A plug-in to get the tone of the Wally Heider "Green Board," used to record Neil Young, Ray Charles, Elvis Presley and Jimi Hendrix

Get the character of the 610’s entire signal path, including tube amplifiers and transformers, and circuit nonlinearities

Control Apollo interface mic preamp gain staging and impedance directly from the plug-in via Unison™ technology

Featuring the UA 610-B Tube Preamp & EQ plug-in

The First Genuine 610 Tube Preamp Emulation

The First Genuine 610 Tube Preamp Emulation

With over three years of development, the UA 610 Collection represents the first comprehensive modeling of the legendary 610-A tube preamp and its modern variant, the 610-B — including their tube and transformer components and all of the unique distortion characteristics of the originals. The 610-A is modeled on a channel from the storied Wally Heider "Green Board," used to record Neil Young, Ray Charles, Elvis Presley and Jimi Hendrix, and offers simple 10 kHz high-shelf and 100 Hz low-shelf EQ. The modern 610-B offers selectable input impedance, adjustable high- and low-shelf EQ, and expanded gain range.

Unison Technology for Apollo Interfaces

Unison Technology for Apollo Interfaces

With UA’s Unison technology, the UA 610 Preamp & EQ Collection blurs the lines between analog and digital, giving you all of the 610’s important impedance, gain stage “sweet spots,” and circuit behaviors that have made it legendary. And just like their hardware relatives, both the 610 plug-ins allow Line and Mic levels, with both 500 Ω and 2.0 k Ω impedance setting options available in the 610-B. Combined with Apollo's physical preamp gain, this provides a tonal range from clean to clipped — with tons of broad, musical sweet spots in-between.

Add Tube Color to any Source

Add Tube Color to any Source

UAD-2 and Apollo 16 owners can use the UA 610 Collection for mixing, adding color and saturation to any source, without going outside the box. Inject your tracks with the legendary warm, natural compression the 610 is famous for, allowing you to place instruments perfectly in the mix while giving them a rich, three-dimensional tube character.

Review UA 610

Basically I don't like vintage old style, it's not my favourite style and I tried this plugin out, but I don't like the sound and the way how it changed my recorded audio with some noise. I don't want to use it in future.

Can't live without this

I use this for drums, especially for snare. It has something I can't get with other plugins I have used or tried over the years.

1960s Heaven

The 610A gives you 'that' sound. It is unmistakably that 60's American sound you hear from The Beach Boys, The Doors, or any other record from that era. This is the holy grail of tube sounds. If you know that sound and want that sound it is simply breathtaking. I've never heard a tube emulation sound as great as this and the V76.

Pretty good

Not sure I would buy these, especially with UA’s crazy prices (even on sale). Got them with the heritage bundle. They sound nice and give you options and help add some weight. At a good price ($30-$50) I’d recommend.

Used a lot

I see many different opinions about this one, some like/hate the sound for being either transparent, or characteristic :P
I really like the 610A for adding warmth and a pleasant bass boost to just about anything.

Sounds amazing

Compared to my previous interface, which was a highly rated one, this sounds amazing with the UA 610 in the unison position. Didn’t know my vocals could sound that good doing recording at home. Worth the switch to UA.

I had to buy it, didn't want it.

This was part of the Apollo Heritage edition. I haven't tried it because I wasn't interested in it. And because I didn't know I bought it. UA is so annoying. It lists you all of the ca. 200 plugins, and you have no idea of which of them are demos and which you own. And scroll 200 plugins. Are you kidding me??? All I wanted to have, was C-Vox. The rest I cannot recommend. And I don't need the rest for what I record with my fantastic Sound Devices MixPre-3 II.

Where is a bypass button on 610B?

When you created a new design for both 610, the bypass button on 610B disappeared.

They're ok, I just think these are pretty expensive considering what they are and the sound quality. I can't hear much different in the saturation to what you can do with 100 other much cheaper plugins, and its hard to dial in accurately with the way the level and output are set up. The EQs are borderline useless too. 2 stars
