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.

UA710TF

This preamp has improved EVERYTHING I have put through it sound- wise. My untreated basement studio and solid performances aside, this preamp has brought character to my recordings. Finding that sweet spot on the 'blend' knob for a source still makes me smile.. it's a beautiful thing.

Great versatility!

Great sound and versatility. I love the tube sound on acoustic guitars, vocals and any acoustic instrument. I also love it when I track the line for an electric guitar to use with amp emulation: it adds that warmth that can't be achieved with the digital saturation/drive of the emulation.

Very simple to use. Great price

BIG and Warm

Tried it on Vocals, Electric bass and El. Guitar Cabinet and Acoustic Guitar and it sounds awesome! It can go from very clean sound to a bit dirty, from fat and boomy to more bright and sweet. I own this for a very short time but I am sure will help me bring my productions to a whole new level!

Excelente Preamp

el 710 es un excelente preamp con gran versatilidad, los tonos que se pueden conseguir son infinitos gracias a que podemos hacer mezclas de transistor o tubo. Funciona muy bien como caja directa para grabar bajos y guitarras.

Perfect Solution

WOW. As a home recording hobbyist I found this single piece of gear to be an astonishing improvement to my process. The choice of trans vs tube. The price point. The UA 710 along with my UAD Solo card have made my recordings sound spectacular. The highs are as glittery as a stripper!! Put it this way, I now MUST take the plunge and acoustically treat my space since it is limiting the sonic possibilities of the UA710TF. WOW

I have bougth this one to find out how good it works. Great one, it works with a Neuman u87 AI perfect. So i decide to buy a twin finity 4-710d. Next days it will comes from my dealer.The UAD 2 Solo from this Bundel i have bought is very usefull too. So i believe someone ask himself why me is giving 4 Stars for this and other products of UA ? The whole Videos, Handbooks, Hints are all in English. I miss a German translation :(. German translation will makes thinks better understanding and working for me. Great work UA, thx for that.

Este es el previo que mas utilizo en mi estudio(estudio Atica)
El sonido es muy bueno
El único punto negativo es el paso de 4 a 5. Que es muy agresivo

Por lo demás es fantástico.

Ce sont des petits bijoux. Facile d'accés, possibilité ou pas d'utiliser la lampe! Vraiment un rapport /qualité prix très bon.
C'est du bonheur de faire des prise de son dans mon home studio!

Excellence heavyweight for the long run

It has all you need. They nailed it with this baby. For many years now it just brings what I need from a mic & line pre-amp. hiZ input sounds de-luxe, put a mic true it and it has a clean to warm sound with the blend (Fet mix Tube) function to top it of. It has al the basic functionality an input needs. Even if you set the input on fire and totally destroy it you will like the X-factor. Great dynamics.. End conclusion: a 10+ Its a fact that many hits are recorded today with this tool in combination with the apollo's. Thanks for reading!

WHAT A GREAT TONE

All of a sudden my AKG 420 microphone sounds like a $3000 mic! I'm very happy with the sound it produces. Also very clean and warm sound for my jazz guitar that I tried.
Vocals sound awesome with it.

The Right Tone Going In

That extra boost!

I use a Roland studio capture interface with an AKG C414, which sounded great alone. By adding the 710 Twin-Finity it added that big studio depth to my recordings in my home studio!

Rocks!

I've been using 710 Twin-Finity for over 2 years, and it's my favourite pre-amp! Almost in every genre, you can use this toy.

Warmness

Had lot of waited warm tube sound. This nailed the coffin. So warm vintage and uniqueness combined. Really worth of every penny. It's now heart of my studio.
