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.”
– Ian Boxill (Lenny White, Prince, 2Pac)Customer Reviews

AVALON Vt 737 MIX Magic!!!
Have had the original AVALON with the purple knobs since it's inception. Added new JJ Gold tubes and it sounds better than brand new. Kept asking UAD for this model and it's excellent!! Recorded the same song twice once using all analog pre amp's. Once in the box ( on Mac ) using Unison. Very small differences , I love the amount of instances for the mix. Many discerning ears could not differentiate the two mixes. Thanks a real keeper in the UAD arsenal. The presets are another add on for me I always just used my ears , but then I rode Dinosaurs to school . lol

This is the real deal
Very very musical compressor, an eq that seems to be made to make tracks fit into the song context and a preamp that improves every sound source. This is a valuable plugin that really makes a difference. Thank you very much!

Avalon VT-737
For me Best software EQ for vocal.It can be pressed hard, but it still sounds very musical !

Perfect Emulation, well done uad
The opto-compressor and sweep equalizer emulations are 99% the original unit.
I gave uad 10/10.A. Norris
Real Vs the Plug
It was sort of romantic to see my AV737SP appear on the latest update of UA-2 plugs. I have run a matched pair since 1997 and love the timbre these units provide. Whilst the +10dB gain boost to the valve-stage embeds some greater "velvet" than the plug I am very happy the "Baby-Face Mod" has been included in the software.
I had my units modified many years ago to multiply the compressor attack time by 4, making the units far more versatile than the stock fastest time of approx' 2 ms.
Love this company's attention to detail - Congrats UA.
