710 Twin-Finity™ Tone Blending Microphone Preamplifier & DI Box


100% Tube to 100% Solid State — a Variable Tone Blending Mic Preamp & DI.

The award-winning 710 Twin-Finity™ is a radically new 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 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.
