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.

Exquisite
This is simply an exquisite emulation. I don't know how the UA engineers get these hardware homages nailed 100%, but I am so grateful for their talents. Crazy good.

Great channel strip
I use it a lot in the unison slot. It is great on vocals and D.I. Bass. Just plain smooth.

Of Course
I dreamed of having one of the hardware versions after recording an EP through one at the studio we used. Now I have it! It's just like the real thing to my ears!!!
T. Long
Very Nice.
Sounds great! Especially the punch kick algorithm. Use that on everything now. Nice one UA.
Think I got it in the Ultimate 10 Bundle which is the sickest bundle ever. It’s a monstrous collection of some really great sounding plugs. So worth the investment!
Don’t take my word for it. Download the demos and hear for yourself.M. O'Brien
Love it!
I didn’t go for this initially because people were saying it is for rap and the spoken word. I was struggling to get bass and resonance into my vocal. Granted I am not a sweet singer. I am more about character vocals. This is simply fantastic.
A. West
Authentic!
UA nailed this one! True Avalon characteristics!
M. O GRAUE
Just like the original!
The Avalon plug in works just like the original and the controls and face are really intuitive!

My new vocal 'go-to'
I have a selection of different mic pre-amp and compressor combos that I have been using in varying degrees. Most recently I had mainly been using the Manley Voxbox... That is until I decided to download and try this VT-737.
The preamp is SO sweet and smooth but with a really open and airy top end. The compressor is fairly transparent and very adaptable, mostly alleviating the need to daisy-chain other compressors into the signal chain. On vocals (which will probably be its only use for me) it sounds absolutely gorgeous and as a 'one-stop shop' Unison insert with sweet mic pre, flexible comp and a really nice EQ section this has just become my absolute 'go-to' in the Unison pre slot and most likely will be for the foreseeable future!H. Barakovic
Awesome
It's a plugin that every sound engineer nust have. Love him.

The 737 Take off - Keep flying high
If channel strips had 7 wonders, the the Avalon VT-737 Tube Channel Strip would be for sure Number 1, this is just not a channel strip , its much more , with any microphone you can play around and get immaculate sound and top quality output . a must have for voice over artiste and surely for all types of singer awaiting stardom . To be honest, Universal Audio did some serious hardwork to make Avalon VT-737 Tube Channel Strip exactly the same like the hardware , probably better ,cause you don't need to worry about the machine rusting or having some electrical issues or maybe getting stolen in these times of inflation, hats off to UA and a Grand thank you for making it available to us. God Bless

Spectacular mic preamp for voice overs and voice actors
In many of the recording studios that I have had the opportunity to go to work, there was the Avalon VT-737.
He has the incredible ability to give my voice a body and a grandeur that few can achieve. Absolute clarity, superb dynamics; and extraordinary strength.
I am very surprised at all that is giving good for me. Since I personally use it in my recording studio, I don't usually use the one I had before. Since the Avalon Vt-737 is far superior.
I recommend it above all to those who are dedicated to voice recordings for commercials, dubbing, narrations, etc. Spectacular!
