710 Twin-Finity™ Tone-Blending Mic Preamplifier
-
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.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 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.

It's my only analog preamp
Love the 710, specially the blend function between tube and resistor. I use it mainly on vocal.

Great unit but not exactly as promised
This unit has been out for quite a long time now. It is a great preamp- musical and solid. I found that if you swap the factory tubes with better ones you get much better results. The tone...

Workhorse of a preamp!
I've had this unit for a while now and it has been a heck of a preamp. No wonder they are still selling them. Great tones and clean sound.

“Ace Of All Trades”
A beautiful tone is a given with the 710 Twin-Finity. But what sets this preamp above the rest are the kinds of tones you can get with it. Leaning on the solid state side for transient attacks (overheads, guitar, metal percussion), and the tube preamp to fill out and warm up vocals, cello, woodwinds provides clarity and separation even before you start mixing!

Leider kann ich meine Finity 710 nicht registrieren, warum nicht???

This unit has been out for quite a long time now. It is a great preamp- musical and solid. I found that if you swap the factory tubes with better ones you get much better results. The tone blending feature is a gimmick tho. Good unit overall but not exactly as promised.

I first had the UA twinfinity 710, but sent it back for a Solo 610, which works very well. However i realised i also like the product of the 710, as it is a very good pre amp, so I decided i wanted, so i re purchased it. iI find that UA products are well made and perform very well.

Every Little Thing UA Does IS Magic.
So, I've been engineering for a while now and one of my pet peeves has always been getting a great hat sound. This was the motivation behind grabbing the 710. It only took a few minutes to dial in the sound I've been hearing in my head all these years. And don't get me wrong, this pre sounds great on guitars too! Very versatile box.

Love It
Just recently purchased UAD Arrow with this 710 and I must say..... it’s the only way to go if you’re the type that love having desk space. Sounds that I’ve achieved with the Neumann TLM 102 and the slate microphone through this pre - amp are phenomenal ! I recommend all to have this setup !

I do not hear Universal Audio quality!
I have two 710 devices and unfortunately I have to say that I am very disappointed. When a device it starts to crack when I turn the poti. I rarely use them. The fact that these devices are so vulnerable may have something to do with the fact that they are "Made in China" and not like other devices (610 Mark2) are not made in-house. I will try to resell these devices and would not recommend them for these devices. The character difference between clean and with tube are very very small. That's why I bought these preamps. You have to be very careful with the tube sound. Already in the middle position it can come in the mix to distortions which are very quiet when recording. But these come after compressing extremely forward. It is best to operate this preamp clean. Who has the money should rather buy a LA 610 Mark 2. Worth every penny but this preamp is not for me Universal Audio Preamp!

Ah quel bonheur!!
Je l'ai acheté il y a quelques années avec ma première UAD2 et je m'en sers pour tout. Voix, bien-sûr mais aussi mes basses, mes guitares avec ce petit "growl" bien chaleureux de la petite lampe (que je changerai peut-être un jour au profit d'un modèle légèrement plus chaud encore). Je l'adore, c'est mon petit pote qui fait tout à la maison sauf le ménage, ça ce sont les plugs UA qui s'en chargent et avec tout autant de brio.D. Boudreau
Not hearing all the hype
Okay so I've read a ton of reviews about this product. How it gives a plethora of tone variety etc. But I don't hear any difference between the solid state side as opposed to tube. Maybe I have a faulty unit I'm not sure. There isn't even a lot of difference between the mic preamp in a little Presonus Firestudio audio interface and this unit. Definitely not $700 worth I'll probably be returning it.

Great product!
I'm really impress with all tone managements on a simple device like he 710 Twin-Finity. Great product for the budget.
Will be better with a stereo output, but works nicely!R. Bouma
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!
