The Universal Audio 710 Twin-Finity Preamp uniquely combines both the classic retro warmth of UA tube design and the transient bite of solid-state!

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.

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.

    Great preamp
    Dan C

    Bought this as an upgrade from an Art Pro pre that I had be using for years and definitely a step up in quality & tone. Using it with a tube mic, so I actually blend in a bit of the solid-state side to pull back the coloration and produce a warm, but still crisp tone. The Hi-Zi on the front is way handy for those direct-in bass parts and a vast improvement over the DI box I was using (no surprise there). All in all, a great unit. The VU meter is a bit small, but I guess that real estate is limited given that two will fit side-by-side in a rack.

    Excelent Mic Pre
    Oscar Pestana

    UA always give us a high quality gear for a fair price. This 710 is awesome! Years and years of project development from Mr Puttnam pionner legacy thru nowadays high end UA technology. I have 2 of them, for stereo recordings, and I must say that they are built like a tank and amazing sonically, from focused solid state to analog warmth tube colors, and everything in between due to this genius blend knob, this gear is a must have. Thanks UA!
