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.

Sounds amazing!

Just acquired this in the plugin of the week deal. I've had a play around with it and I'm very impressed. I'd held back on it before as I don't often record vocals which most people seem to use it for. I've tried it on bass and synths and it sounds great and a little different to my other channel strips. Pick it up now especially at this price, you won't regret it.

Saved me a bunch of money vs buying the hardware version.

Like others, I wish the interface was resizable but sound-wise it's great.

Pensaba que sería "otro plugin más", pero no es así. Es increíble el carácter que se puede conseguir en una voz con este plugin. No puedo decir que suena igual que el original, no tengo uno, pero tampoco me importa ni lo necesito. Gracias a este plugin ahora sí consigo el típico sonido característico de las voces "agresivas" de música urbana. Lo compré en descuento, pero si tuviese que volver a comprarlo por 300 dólares lo haría. <3

Best software preamp I ever used !

If you're into modern-polished vocal sound, this might be your best buy. The 32K eq band is absolutely crazy and the saturation is so full, crisp and clean. Add a 1176 and you're getting a perfect chain with 2 plugs. Resizable GUI is however necessary !!

Got it back

I sold my Avalon 737 when I purchased my Focusrite ISA828 which I really love. But I never got the same vocal richness that the Avalon delivers. Well I am here to say after 8 years without it…I got that sound back in the UAD Unison Avalon plug-in. Just like I remember. I am so pleased!! Great job UAD!!!
