Capturing the Sound of Modern Music
After carefully auditioning multiple Avalon 737 hardware units, the UA team selected a "golden unit" with the ideal optical compression response. UA's DSP team then artfully captured the target hardware's class-A tube amplifier section with custom-wound transformer, LED-style optical compression, and discrete four-band EQ — the signature Avalon sound heard on thousands of chart-topping hits.
Unison™ Technology for UA Audio Interfaces
Harnessing UA’s groundbreaking Unison technology, the Avalon VT-737 plug-in captures the hardware’s mic preamp impedance, gain stage “sweet spots,” and exact circuit behaviors, giving you all the detailed sonics of the original Avalon hardware — including its gentle high-pass filter for removing mud and low-end gunk. And because the VT-737's front-panel Hi-Z input is a legendary bass DI, the VT-737 plug-in's Unison-enabled Hi-Z input endured rigorous evaluation, ensuring it was virtually indistinguishable from the original hardware.
Versatile Optical Compression
Excelling on vocals, bass, acoustic guitar, and voice-over work, the VT-737 plug-in's dynamics section emulates the hardware's gentle touch, rather than adding squash or crunch. Its relatively transparent compression also make it perfect for "stacking" the compressor again at mixdown, expertly controlling the dynamics of a vocal in a dense mix. An exclusive plug-in only, super-fast mode gives you “X4” faster attack, pushing the VT-737 beyond its physical limits, affording you tons of new dynamic versatility.
EQ with Details
The Avalon VT-737 Tube Channel Strip plug-in expertly emulates the hardware's discrete four-band EQ, allowing you to sculpt lead vocals with a visceral, larger-than-life presence and sophistication, placing them front-and-center in any mix. Like the hardware, the EQ can easily be placed before or after the compressor, and the mid bands can be engaged as sidechain filters for laser-focused compression. And with the 32k high frequency "air band," you can add delicate shimmer to everything from strings to background vocals to acoustic guitars.
Add Chart-Topping Sheen with Any UAD Hardware
Of course, the Avalon VT-737 Tube Channel Strip isn’t just for UA Audio Interface owners. UAD hardware owners can use the VT-737 Tube Channel Strip plug-in on any mix, giving your sources legendary fat bottom, "glassy" top-end textures, and a bevy of clear-eyed color — without ever going outside the box.
“The UAD Avalon VT‑737 plug‑in captures all the details of the hardware — from the preamp to the EQ and compression — this emulation is spot on. UA nailed it with this one.”
– Mike Larson (Pharrell, Ariana Grande, Migos)
“The Avalon VT-737 Tube Channel Strip plug-in captures the hardware perfectly. Plus, it's incredibly versatile, allowing me to add polish to vocals or warmth to bass.”
– Eric J Dubowsky (Flume, Odesza, Weezer)
“The UAD Avalon VT‑737 plug‑in is an indispensable recording and mixing tool with texture for days.”
– Hector Delgado (A$AP Rocky, Selena Gomez, Lana Del Rey)
“The UAD Avalon VT-737 Tube Channel Strip is an amazing sounding emulation. It’s a must have in any modern engineer’s toolkit.”

I have dreamed it True
The VT-737 is the beast I've always considered to possess. Now, when you can get a plugin to almost emulate the real thing, you get to consider followings:
1) how you can spend the huge amount of money you saved purchasing a plugin sounding like the real one for a good 70%
2) no gear to be afraid of a theft (it could be an issue)
3) ease of setup
I love it. I "have it"
Lovely addition to my plugin collection
I love using the Avalon 737 plugin as a Union plugin via the console before I even start using my daw. Wonderful sound.. sonically sounds like a replica of the actual legendary Avalon 737 preamp. Thank you Universal Audio for such an advancement in recording.

Emulación muy depurada, un pre amp muy limpio y de gran color, 100%recomendado
This is a plugin that goes Far Beyond Expectation.
This really is an amazing plugin. Bringing an incredible sound that does justice to all history and respect for the physical apparatus. Very good and versatile.
Adds lovely yet transparent color to VO
I’m a professional voice actor and audiobook narrator, and while I’m still learning how to use this as a unison pre—it just takes the raw signal to a more polished and clean place—and with light compression to smooth things out and very minimal eq to round off some of the edges from my voice/mic/room resonance. Still trying to find my sweet spot, but so far I’m very happy to play around with it.
I have a MacBook Pro 2017 i7 16GB, Apogee Duet 2, Garageband, Shure SMB7, Mackie 802 VLZ4 and a small closet. I would love to get this Avalon vt-737 (plugin) for Vocals, I want to record clean vocals, Is this plugin compatible with garageband? and the plugin VT-737 needs registration renewal every year? and how much the renewal fees if there is.
Avalon SP 737
Hi, I have an apollo twin quadcore. I love the quality of the mic pre's. I have tried pluggin's for my interfaces for a number of years and I hired an Avalon 737 to compare the difference. I cant help but notice that I was able to get a slightly more sonically better recording on an accoustic guitar...which is what I was looking for. Im not sure if software pluggins will ever satisfy my desire for a better sounding recording. I guess time and a lot of coin will tell.
Go-to for tracking Vocals!
Very clean, intuitive, and fun to use! Sounds wonderful!
i use it for union pre recording and it works well
I have a vintage_ 1st model. You really cant judge an emulation correctly without understanding/having material comparison. So close if used correct
Wonderful channel strip.
Love how easy it is to get a clean modern sound. Really smooth.

Sweet and Powerful
I really didn’t think I would need another channel strip - until I heard what the Avalon could do to the lows and the mid-high frequencies of anything you pass throught it. It became an integral part of all my basses and almost all my vocals. Simple to use, sweet and powerful sounding. Beautiful.
An Amazing tone mic pre
A new boutique UAD plugin that gives me a choice of tonal signal on my recording tracks on voices and any accustic instrument. It gives me a tonal character with clarity, musical energetic musical sound that it's so versatile that it's one Channel Strip mic pre that must have as a first choice for everything. Universal Audio you really created an unbelievable emulation compared to the hardware unit that sounds identical. It's deminantelly a musical box that sounds like thousands of dollars.

Best plugin period
The coloration and smoothness this thing delivers is mind blowing. I've tried alot of the preamps but when I tried the demo on this thing I had to purchase . With the levels hitting at the right levels don't really need eq or comp with the many options this thing has
Give that smooth and clear sounding vocal i absolutely love it
