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.

Absolutely stacks up against the hardware!

I've used the hardware VT-737sp to record a number of albums, over the years. Even after only a very short period of using the UAD version, I can absolutely tell you that this stacks up alongside the hardware version. The smooth dynamic control, that sweet EQ - it's all there. 100% worth the buy!

Must Have

I purchased this plugin because this is the pre amp that Dr. Dre did the Chronic albums on and I must say this is a must have if you record hip hop vocals.

Excellent Tone!

I was introduced to the Avalon from some producers here in LA that had the actual hardware. I had never heard of it before I met them. I noticed the tone and crispness on their vocals for the records they were recording and I assumed that a lot of that came from the Avalon. I was correct in my assumptions. This has been my go to Pre-Amp so far. I'm happy with my purchase!

I love it

처음 사용해 봤는데 마음에 들어요.
개인적으로 neve 1073보다
제가 하는 음원과 더 어울리는 사운드라서 만족스럽네요.

You dont know bass until you DI with Avalon! For vocals, the ability to sidechain instruments leaves space to punch through! Vocals and Bass this is AWESOME CENTRAL!

I’ve struggled to find a preamp that doesn’t roughen up vocals too much. I demoed the Avalon and I was blown away at how smooth I got vocals sounding. Maaan i’m gonna marry this thing

A Real Game-Changer!

Used this plugin for a mobile recording gig. Client was using a run-of-the-mill Shure SM27 in a relatively untreated recording environment. After the first take he literally couldn’t believe what he was hearing on the playback. The crispness and clarity are second to none. Gives the vocal that wonderful airiness that we’re all looking for. My only complaint is that I didn’t buy this plugin sooner.

Great sounding Preamp

I have wanted the Avalon ever since I got into music production and recording artists. Once I saw that Universal Audio created the emulation I knew I was getting it. The warmth adds quality to the vocals. Very impressed.

Une très bonne tranche de console.

Je n'ai jamais eu l'occasion d'utiliser le "hardware". Mais le plug in Avalon 737 sp est très efficace. Le son devient plus beau, doux. Bref, il est bien.

Wow!! I’m newer to mixing (5years), and I’ve become familiar with a vast different number of plug-ins but THIS plugin did something magical as soon as I slapped it on a Vocal. Warm round and tight, but not too tight is how I would describe it. Not too familiar with the world of tubes either (lol), but this has peaked my interest 10fold.

When You Need It

It's not good on everything but it's perfect when it's needed. The compressor section is as transparent as I've seen. The EQ has the best high end I've used. A must have is the final conclusion

It makes Vocals sound Heavenly

I added this to my input Chain, before my distressor and the 2 together are beautiful. Even clients noticed. I don’t know why I didn’t get it sooner. Must have if you’re doing vocals (that’s all I used it on)

Classic staple unit of the 90s and 2000s. I even use it on masters to help kill a little digital top. The compressor rocks as well. to the folks leaving poor reviews over the amount of presets, grow up and read the manual. Theres like 5 knobs that all do very obvious things this isnt rocket science

Very Versatile

This plugin is great in unison, and provides a nice front in. I alternate between it and the Nieve 1073, depending on the sound source and what I am in the mood for. It also serves as a great insert for many applications, especially bass; it has become my go-to for bass.
