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

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 have Vt-737’s in 3 rooms and have been using them consistently for years. ( mainly on hip hop and r&b vocals ) The only major difference here is that the knobs and buttons are on a computer screen instead of hardware. Other than the Huge price difference , a plus to owning this plug-in is that you don’t have to warm up or change blown tubes...

Works like the Real Avalon PreAmp

I was working in a studio with an Avalon Preamp for about 9 months. Now that I am in quarantine and I don't have access to the studio, I bought this Avalon Pluggin to continue my work from home. Wow I am impressed, its like working with the real one!

Thanks UA

This is Some how better working than the original unit I had at my studio last year, I know it´s not fully analog sounding but its offering operational extras that the original one and hadn´t? because of the stereo, I had only one channel at my studio, now I can do a lot of very useful stereo tasks in a stereo channel with this plugin. Thanks UAD

Love it!!

I own the Avalon hardware preamp, but this emulation is amazing! Now I rarely use the hardware unit. Love it for vocals and acoustic instruments. Pushing the 20 or 32 k band eq a little after de-essing provides nice air to a vocal without the digital artifacts that often come with boosting other eqs. Has a musical sounding compressor that can add a nice warm texture if that's what you're seeking

The most impressive channel strip Plug-in

This has got to be the most impressive channel strip Plug-in ever created, it just sounds great in most sounds with a slow attack like (vocals, strings, brass) it’s a beautiful simulation!!!

Gorgeous Tone....

One of my favourites, absolutely spot on the hardware. This is a very special plugin, some time has definitely been spent here. One of the best compressors in a plug in available. I find myself pulling up this software for pop production constantly, and if you're on the hunt for some LA vocal sheen, this is it folks. Transparent, open, punchy... all the key factors that we all look for on a pop production....My word..what a hit.

Vocal Perfection!!!

Anyone who is serious about a SMASH HIT
knows the vocal quality has to glisten in the mix.
The Avalon VT-737 is the vintage industry classic known to make vocals sizzle and come to life!

Avalon VT-737 makes my Schoeps MK2H stereo pair, which I have found to be a bit "too neutral and harsh", sound really great! It gives the sound certain warmth and focus, which I never could reach with any EQs.

Just what the MIX doctor Ordered

All I can say is wow .. what I difference it makes on the mix and vocals! If you don't have it try the 14 day demo first and buy before the sale is gone!
