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.

Un preamplificador plugin igual a hardware

Es increíble con la tecnología unison suena igual al hardware, las felicitaciones para Universal audio por el trabajo minucioso, están en todos los detalles.
Este pre en formato Hardware lo utilice cuando trabaje en un estudio pro de Uruguay.
Ahora que tengo la forma de probarlo en formato software es increíble, uaudio ha realizado magia, solo queda agradecimiento. Ojala pueda obtenerlo ahora solo estoy usando la demo.
Si tienes dudas, te digo mas de 25 años de experiencia tengo y este Avalon vt-737 es fantástico.

Awesome Sound

Great compressor and fabulous EQ. Don't forget about the x4 for the attack on the compressor, you might need it.

Used on bass & vocal track so far. Damn is this worth it.
Presets are spot on with only minor changes to dial it in perfectly. Smooth. My new 2nd favorite plugin

Seems good

I rushed to purchase it when I purchase Apollo interface thinking it would be great for bass. But in the road, I found that other preamps like Helios and Neve, even UAD 610B are more suited to bass. It shines in vocals though. I Don't know how it compares to the real thing but honestly I don't care.

The best

Without a doubt, this is the best EQ II’ve ever used. It has made the single biggest change as far as plug-ins go to my work.
