Universal Audio 710 Twin Finity 1-ch Tube & Solid State 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.

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.

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.
