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 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.

710 ...blending like a dj mix ...

It's a fantastic piece of gear. I couldn't believe the difference is so big compared to the first preamp i had . I'm really happy with this hope i can save for the others from UAD to , it really has its own character ! Love it !!

Really useful!

I noticed a big difference the first session I used it on a lead vocal I was recording. Adds a nice character immediately. I've used on electric and acoustic guitars as well and sounds great. Also works great on my Hofner bass direct.

Excellent

Very attractive design. Controls are simple and straightforward. Owner's Guide is especially useful. They have gone to the trouble to assume you know nothing and they lay it out step by step. You don't see this much anymore. It helped me greatly. Now I do more listening and less fiddling. Strongly recommended.

Finally found what i was looking for

I have been buying and selling preamps for a while and decided to try the UAD 710. All i can say is, i am done searching. Straight to my interface and into my DAW with no EQ it sounds amazing. For xtra clean, dial to the left, add tube color to the right . Simple. Love this thing. Keep it up UAD!

To everything you want.

I've bought one 710 Twin and for sure I'll get another to make it Twis. For acoustic guitar, for drums, key and vocal. Everything you need it sounds good.

Genial el 710 twin

Llevo un tiempo con el y me parece muy versatil, le da al sonido un fuerza que si todas las pistas han pasado por el 710 notaras que todo suena con un color muy distinto al que estamos acostumbrados con los previos de las interfaces, la conparo con los previos d-pre de yamaha y los de la ediro fa 101, y se nota mucho la diferencia, el cambio entre estado solido y valvula es muy sutil, pero lo suficiente, la configuracion que mas me gusta es la intermedia, al igual que dice aguilera la gabancia en mi caso del 3 al 4 es muy brusco el cambio y eso hace que pierdas un poco el rango de posibilidades pero en general es un buen cacharro calidad precio de un buen mivel para estudios de proyecto y hone studio,
Estoy muy satisfecho con la compra.

Twin Finity brought my mic back to life..

If you are new to out board gear, and unsure of where to start, this is the best starting point!!! Price is a more than reasonable!!! And will give pretty much any mic more character..

So versatile

I've been so impressed with the versatility of this preamp. The tube-to-solid state option is incredibly flexible. I've had great success with this on electric guitars, vocals, and DI bass. Build quality is rock-solid and I like the half-width size. Makes it easy to want a second one!

Loved it so much, I had to have the 4-710d

I bought one of these to have a good tube preamp around the studio, and liked the idea of the Twin-Finity's versatility...clean to saturated, thanks to the Blend knob.

What I didn't know at the time was how important it would become in all my tracking...I started running an awful lot of gear through it, and found that tracks recorded through it had such a presence, and sat well in the mix, too.

So when UA released the 4-710d...well, it'd be an understatement to say that I was intrigued. The same functions as the 710, but with FOUR channels, limiting and 8-channel ADC? Greatest. Idea. Ever.

After explaining the importance of this product to my lovely wife, I ordered the 4-710d through Sweetwater. Cannot wait to have FIVE 710 channels!

LOVE! I'm a Voice Over performer and this little unit retrofitted with a 1960 long black plate tube from RCA makes this baby FAT AND WARM! The solid sate side gives me a clean and relatively uncolored sound for industrial reads. But when you roll it over to the tube side it's magic coupled with My Rode NT2A set copletely flat.
For the money, nothing touches this unit for it's sound and capability.
