Take a Listen
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.”

Incredible plugin, although not as close to the original hardware
Just to say this plugin sounds amazing, preamp has 'the touch', compression is good (although the hardware can compress more being more transparent) and the eq works really well, not to say...

Avalon VT-737 Tube Channel Strip

Amazing !!
I’ve owned the very expensive 737 for years and it was always the first channel strip I’d go to for vocals. It was also the first high end channel strip I owned and I saved for months just for a down payment to end up financing the balance. I used the trial one day for a female vocal and my jaw dropped as to how accurate it was to the hardware unit. Of course I’m the only one in the room that cared to notice and everyone is looking at me like I was in a coma. If you’re like me and slowly realizing that expensive hardware like the 737 can be emulated so well nowadays save your money and use the trials to make decisions. Whenever the hardware or emulation debate comes up I always say use your ears and then ask yourself if the end listener will know that you used a $3000 hardware version or a $99 plugin (I used the sale) I would guess the listener wouldn’t know or care if they are enjoying the song, so where’s the argument now. This plugin is worth owning and you can unrack the expensive beast if you own it and get some cash back.

Just to say this plugin sounds amazing, preamp has 'the touch', compression is good (although the hardware can compress more being more transparent) and the eq works really well, not to say the transparent hpf. But the magic is the routing options you have, which makes it a real workhorse. In combo with the Tube-Tech CL1-B is a magic chain. Sinceraly, everyone should get it

Beast Processor
Definitely, my number-one choice between any other pre-amplifiers is this peace of gear.
Thanks a lot for bringing analog sound and unison technology into the digital plugins to use.
This is a great job!b. cheung
Great
Tames my 808's without losing the punch. Have not tried on vocals and need to learn this plugin some more. But happy with it never the less.

Great Plug-in, but ..
Great Plugin, definitely needs some love on the GUI, please add the option to scale the GUI by % , could be great have manual control of the oversampling.

Cool stuff
Working like a dream. Perfect on vocals
P. Coffin
Pretty Breathtakingly Good
I have the hardware, and this is easily 90% of the magic - but I'd say don't compare it to the hardware, that's really not the point. This thing sounds amazing! Recording + Mixing both level up from using this where it shines: vocals and acoustic instruments!
