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.

Just incredible and eerily accurate to the hardware!

I know first hand that you do not need to use an expensive microphone to see what UAD’s Avalon can do for you. It sounds so clean as a preamp (Unison) and I can’t recommend it enough. No other company comes close to emulating hardware like UAD & the Avalon is no different. A new mainstay for me vocally and even on bass/guitars. Thankful for UAD.

While I can't compare this to the hardware unit, I think what's so great about the Avalon's sound is it's clear and smooth preamp sound, and the "energy" and "movement" of the compressor - it has a lot of character, and this certainly captures that. It makes sense to me why the Avalon is considered a go-to for rap and pop vocals, it has a very strong and BIG sound - and the EQ on this is also brilliantly smooth. This is truly an amazing and beautiful sounding plug-in.

Versatile and Brilliant

LOVE this plug-in. It's simple, easy, and sounds great. The EQ portions of it make it incredibly practical. I'm using this extensively on vocals and individual instruments. Can't recommend it highly enough.

Purchase this plug-in now and get a taste of the industry standard in your DAW

This is the best tube channel strip/pre and is authentic to the hardware. Although digital signals distort when you push them this plug-in rounds out at the top and it does a great job of imaging its analog big brother. I have recorded some amazing tracks through this, you can really get many different sounds out of this box, I've used it on everything from drums to vocals and been really happy with the sounds I got, it has seen a ton of use and performed flawlessly, Looks and sounds like a million dollars to me!

so crazy

I am very familiar with this sound and have been lucky to track hours, upon hours of vocals with the analog version. Now I don't need to worry whether or not a studio has a 737 because UA's analog emulation is second to none! I've done my own A/B comparison.

Must have!

Suitable for classical genre/acoustic instruments

Works well with solo trumpet stereo recordings attempting to emulate orchestral halls and symphonic greatness.

Wow !

I watched a lot of videos before I purchased this plug in and all I can say is wow. I took a voice note off my phone, ran it thru my Apollo inputs with this plug in. All I can say is that it made a big difference and I haven’t really used it like I want to yet.

Silky smooth precision from a studio standard!

I demoed the Avalon right when it came out ! We have been using the hardware version the studio throughout our recording career for bass for recording vocals and was so happy to see that UAD had modelled the Avalon. It is without a doubt my favourite silky smooth precise compressor and EQ! I own and use regularly the Neve 1073 the 88RS and the API vision strip and the Manley set. They all have their own sound but the Avalon ads that warm natural silky smooth sheen and vibe to complete my kit! Thanks so much UAD , now I have to buy another Mic to upgrade my setup!

I had the hardware version of this, the plug does a real good job. You can really crank up the preamp gain.
