Get tube and solid-state sonics and everything in-between with this unique mic pre/DI.

The award-winning 710 Twin-Finity™ is a radical UA mic preamp design that combines both the classic retro warmth of tubes with the transient bite of solid-state, all in a 2U, half-rack unit. The 710 was created specifically to add the tonal versatility and sonic inspiration missing from generic audio interface preamps.

Tone blending is continually variable between 100% tube and 100% solid-state, offering a practically infinite range of unique preamp tones, plus the ability to easily dial-in your own signature sound. There are lots of sensibly priced solid-state and tube preamplifiers out there, but the 710 Twin-Finity is the only one that offers the best of both worlds — as well as everything in-between — all in one box, and within reach of any serious project studio’s budget. Includes a 19" rack-kit for mounting one or two units.

Now You Can:

Harness the distinct sonic properties of tubes and solid-state in one unique preamp/DI

Blend between tube and solid-state sounds for myriad textures and tones

Unlock the potential of your mic locker with a powerfully versatile preamp

Easily track guitar, bass, or keyboards with the front panel 1/4“ Hi-Z instrument input

The Ultimate in Mic Pre Flexibility

The Ultimate in Mic Pre Flexibility

The key to the 710 Twin-Finity’s sonic flexibility lies in its innovative circuit design, featuring a solid-state transimpedance input amp simultaneously driving separate, phase-aligned tube and solid-state gain stages, which are then summed to a single output. The mix between the 310 volt single-ended class-A triode tube stage and solid-state transimpedance stage is controlled via the "Blend Knob" labeled "∞". Blending is continually variable between 100% tube and 100% solid-state offering a practically infinite range of unique pre-amp tones and the ability to easily dial-in your own signature sound.

Drive for Days

Like all our other preamp designs, the 710 features dual gain-stage controls (Gain/Level) which can radically vary the amount of coloration and distortion by allowing you to crank up the input gain like a guitar amp. The VU meter features a unique "Drive" mode allowing you to see how hard you are driving the input stage.

Le plus tout terrain de mes preamps. Fiable autant sur les voix que instrument et meme sur l entree Hi-z....seul bemol l ambiance souvent amplifiée face a d autre preamp classe A au meme niveau d entree ce qui peut deplaire, il suffit de savoir doser!!!

This pre amp is a very good product. It really does the job for me. I am able to blend my vocals depending on the type of song I record which makes each project different.
This being my first piece of UA hardware and definitely not my last! Thanks

Talk about versatility! Need clean Solid State need rich and think Tube - or anything in between, the 710TF has it. I also own the 6176 making the 710TF my other "go to" in the rack. Perfect for anything, however I have found it my favorite for mic'd acoustic guitars. Using the TRANS/TUBE control helps me to dial-in the right amount of crisp and grit as needed for the particular track. This is a must have in any rack.

A brilliant tool for almost everything. Clean or overdriven, i like both ( maybe a little bit too easy to distort
but...) Tube or solid-state , both are great and different. It's not a all tube pre-amp, so don't expect to have the TUBE sound of the 610, but it gives some nuances needed in solid-state recording. SOUNDS GREAT !

This is a great preamp that I've used on both vocals and guitar to add a little crunch/fizz to the tone. Really helped with one particular vocal where it caused it to sit lovely in the mix.

Awesome!

Sound - The best sound for Baglama (saz) recordings
Operation - quick and logical
Equipment - I would like to wish a great limiter from me in this great point
Price - Is it necessary to say anything about it ... for the Universal Audio sound almost for nothing

Conclusion - For me and my shots of the preamp from 2011!

Good product, multipurpose. An integrated compressor would be great but good product!

Sounds absolutely perfect.
For some vocalists sometimes i have to add some more gain at the soundcard.

This is really great to mix 2 very different sounds(trans/tube).

J. Teeters

One of my absolute favorites hands down! One pre that is Solid State and Tube. I absolutely love using the 710 in the mix on everything from bass to soft synths. I literally could not live without this fine specimen of Pre/Di.

This is the best pre-amp I have ever used. Simple to operate, consistent sound, durable and it integrates with my (small) set-up perfectly. I recommend this to anyone who asks me how I get my voice-over clips to sound "that way".
