Capture the Sound of Modern Music

Capture the Sound of Modern Music

By artfully capturing our "golden unit" Avalon's flagship VT-737 hardware's class-A tube amplifier section, LED-style optical compression, and discrete four-band EQ, you can give your tracks the signature Avalon sound heard on thousands of chart-topping hits.

Record Vocals and Bass “Through” a Hit-Making Tube Preamp with Apollo

Record Vocals and Bass “Through” a Hit-Making Tube Preamp with Apollo

UA’s groundbreaking Unison technology lets you track in realtime through the Avalon VT-737 Channel Strip plug-in using your Apollo, giving you the chart-topping sound of the original hardware’s line/mic preamp impedance, gain stage “sweet spots,” and exact circuit behaviors.

Experience Versatile Compression on Vocals and More

Experience Versatile Compression on Vocals and More

Excelling on vocals, bass, acoustic guitar, and voice-over work, the VT-737 plug-in's dynamics section gives your tracks the hardware's gentle touch, rather than adding squash or crunch. This transparent compression is perfect for "stacking" the compressor again at mixdown, so you can control a vocal in a dense mix.

Fine-Tune Your Mixes with Bold EQ

Fine-Tune Your Mixes with Bold EQ

The Avalon VT-737 plug-in's four-band EQ, gives your vocals a lively presence and sophistication, placing them front-and-center in any mix. Like the hardware, the EQ can 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.

Superb Tube channel strip plugin

The Avalon VT-737 channel strip is just awesome. As transparent as you want i to be or as nasty gritty slamming as you want. An all in between go to channel strip plugin for any application.

Interesting understanding of customer orientation

UAD waits until you have bought a plugin for full price and sends you exactly one day later a loyality price offer for same plugin. I like their sense of humour :-D

Like the hardware

Ive been using the hardware for 20 years, but didn't use this emulation until the native version dropped. Sounds as good as you could possibly expect and definitely captures the spirit of the analog unit. At the very least it allows me to match recordings made seay from the hardware. Thumbs up.

avalon vt737sp Review

난 실제 아발론 vt737sp를 가지고있었다.마이크는 u87ai 를 사용했고 오디오 인터페이스는
rme fireface 800을 사용했었다. 시스템을 아폴로트윈으로 교체하면서 vt737sp plugin을 사용해보고 실제 vt737를 판매하였다. 그만큼 근접한 뉘앙스를 내주었다 훌륭한 플러그인이다.

AV 737

This thing is smooth and I love the comp for gentle tracking squeeze db or so. This is in my chain 50% of the time if tracking via the UAD

Surprisingly Faithful to the hardware

I have had the hardware 737 for many years in the studio. For those considering the hardware unit save your money, A/B this plugin and the difference to my ears anyways is so marginal that I recently just sold mine and leaning towards moving to in the box mixing and recording.

Tracking magic

This is the greatest channel strip for tracking. Put it in the unison spot (or not if you don’t want to commit). The gentle compression will sound transparent but stop overload and the tube harmonics are beautiful. Vocals, bass and acoustic guitar seriously shine.
