Capturing the Sound of Modern Music

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<sup>™</sup> Technology for UA Audio Interfaces

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

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

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.

I got this with my Thunderbolt 3. I have the hardware and this is really close to it. Good thing is i can have Avalon sound on the move.

I agree with all these positive reviews. This plugin’s sound quality is exceptional. Well done, all.

I have never had the privilege of using or even touching the hardware, so I can’t compare it to that, but the plugin sounds Just great.

Great for bass

I know this is mainly used as a vocal front end but, on a whim, I tried the demo of the Avalon as a high-end DI emulation for bass guitar and was seriously impressed. I’ve now bought the plugin and use it for all of my bass needs as well as for vocals, horns etc. It’s pretty much displaced the Eden and Ampeg bass amp plugins whenever I want a clean modern sound with presence and a solid low end. Great piece of kit.

I've been using the hardware for years, and I'm impressed by the emulation.
Amazing job, UAD ! When you have a good and expensive mic, you want to make to route to a trusted mic amp. the VT737 a highly recommended and trusted amp you can use with complete peace of mind.

Vocal Magic

If you want something solid, silky and full this is the piece you need. Will be a staple in your studio as well. Can’t beat having as many Avalon’s as you can at once!!!!

Great Sound

Makes vocals sound amazing. A singer I work with loves how his voice sounds so warm and punchy. Dont even need to process his vocals much after. Great Product. You guys at Universal Audio really matched the original Hardware great job.

Avalon is a must...

Just when I thought I've got my vocal chain already set, then this plugin came and...
Just like a real unit, this fellow gives you a special juice, character and great sounding signal for any material that runs thru it. I usually use it as my first plugin in chain like I would normally do it in a hardware setup scenario. I don't own any of the Apollo interfaces (yet) but I'm sure that with its Unison technology, you can use it when recording into you daw and the result would be identical to what and actual hardware unit would gave you. I think it's one of those must have plugins.

I knew but didn't know... Would give this 6 stars if possible!

I somewhat always knew about the Avalon, but some ppl will try to downplay the Avalon and say everyone uses it, or go HD, etc... But being on a budget this was perfect, the sound of this feels like I just gave myself a record deal lol

Sounds so good, I put out an album last year but re-recorded and re-released after recording w/ Apollo and Avalon. Listen for yourself below...

Amazing, and so easy to use!

This is a great plugin. I picked this up having waited til it went on sale. Now I have access to a really famous piece of kit and understand just why everyone raves about it.

Pretty damn good

Im a 27 year recording engineer and producer , having worked in many a studios over my career I can say this is almost as transparent as the real thing. It's a dsp hog , can use but maybe three or four additional plugins on a solo with virtuals on.

Intente testear el Avalon en principio ni bien lo lanzaron y acto seguido quede enfermo de tenerlo... Sinceramente años esperando tener estos Tubos y a este valor, movil y que suene al Cristal que quería... Ok se pasaron del limite de lo probable UA y siempre demasiado acostumbrado a hacerlo a punto... By Universal Audio gracias
