710 Twin-Finity Tone-Blending Mic 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.

* Classic Putnam 610 console mic preamplifier and DI
* Legendary all-tube sound, at a project studio price
* Gain, Level, and Impedance selection for maximum tonal variety
* Backed by 1-Year limited warranty

The key to its 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.
