The award-winning 71 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 71 was created specifically to add the tonal versatility and sonic inspiration missing from generic audio interface preamps. Tone blending is continually variable between 1% tube and 1% 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 71 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.
