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

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.

My favorite

I absolutely love this plug-in. It is my go to unison preamp for upright bass, vocals, drums, acoustic guitar and just about anything else. I prefer the an over the b but both are fantastic and musical. One thing I like to do is use it for tracking then sweeten some tracks in post with the Neve 1084. Still amazing on its own with the 175 comp for some great vintage sounds. Thank you UA.

Fabulous sounding Pre

I recently spent a full day reviewing pretty much all of UAD's pre collection in demo mode; what a fascinating exercise that was. I already own several of the Neve models, which have become indispensable to my studio.

In this case, I was looking for something to complement a growing bass guitar collection; something that would let me record DI. I just want to enhance the natural character of the bass, be it a vintage P, a jazz, or something modern with Bartolinis. I can skip amp models these days, good as they are, because a nicely driven pre into LA-2 gets me everything I need.

For the vintage guitars, I found UA 610A the standout. Drive it a bit, and it really is an awesome, gorgeous sound, with a sweet, slightly grainy warmth to it.

Great for vocals too.

For more modern sounds, I slightly prefer the API, which is clean, chunky, dimensional, and which has a beautiful natural compression to it when pushed.

But this 610A now lives on my unison input for all things bass. It is also great on vocals, after the event, or for tracking. Give it a try, listen carefully, and see what *you* think. These things are somewhat subjective.

The 610-A plugin is the Secret Sinatra Sauce

I don't use the 610-B very much, however the 610-A plugin is pretty much my go-to for any kind of vintage Sinatra type sound. The way the voice breaks up on the peaks is really familiar and timeless, especially if you're a fan of Frank Sinatra. You will have to carefully set your gain staging BEFORE entering the plugin, and then take care to use the impedance and mic / line settings appropriately, but if you do it right, you can get a vocal track that's pretty reminiscent of Sinatra's recordings. I don't know if the 610 hardware equivalent was actually used in those recordings, but just that it sounds very close to it, to my ear.

UA 610 Collection

Great having both the 610A and 610B in the arsenal. These two, along with Neve 1073 and 88RS are providing a lot of versatility in tracking options.
