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™ 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
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
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.

I really didn’t think I would need another channel strip - until I heard what the Avalon could do to the lows and the mid-high frequencies of anything you pass throught it. It became an integral part of all my basses and almost all my vocals. Simple to use, sweet and powerful sounding. Beautiful.

An Amazing tone mic pre
A new boutique UAD plugin that gives me a choice of tonal signal on my recording tracks on voices and any accustic instrument. It gives me a tonal character with clarity, musical energetic musical sound that it's so versatile that it's one Channel Strip mic pre that must have as a first choice for everything. Universal Audio you really created an unbelievable emulation compared to the hardware unit that sounds identical. It's deminantelly a musical box that sounds like thousands of dollars.

Great Preamp
The Avalon Tube strip gives tube character and saturation with clarity. The smoothness and the way it helps things sit, especially with vocals and acoustic guitars. Works great as a mixing plugin but really shines in the Unison slot.

SMOOTH
Smooth is the best word for this mic pre! Smooth compression, smooth high end and smooth sound.. love it! I would still love to try the real unit but for now.. this is perfect!!
E. Wells
Make your tracks shine
Wanted to try this out on prerecorded material since most only talk about it as a Unison plugin.
Could not believe the difference it makes on existing vocal tracks a definite winner.
Love this plugin.R. Neville
Owned the hardware
Sounds pretty identical to the actual hardware unit.
e. sanchez
Excelent
Es excelente suena muy parecido al hardware. Ideal para poner en la entrada y grabar con la calidad y sonido final

Just Beautiful
Makes a 500 dollar acoustic sounds like 5000 dollars. Just delicious to the ears.
A. Tkachenko
Wow Preamp Avalon is the best
This Avalon preamp is so good. I’m dreaming about it
V. Arnold
Silky smooth
Finally decided to pull the trigger and try this. For hip-hop and R&B vocals it's an instant go-to unison plugin. I don't even use the onboard compressor or EQ much, the gain stage alone is more than enough.
S. Crewe
Absolutely stacks up against the hardware!
I've used the hardware VT-737sp to record a number of albums, over the years. Even after only a very short period of using the UAD version, I can absolutely tell you that this stacks up alongside the hardware version. The smooth dynamic control, that sweet EQ - it's all there. 100% worth the buy!
