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.



  • Harness the distinct sonic properties of tubes and solid-state in one unique preamp/DI
  • Blend between tube and solid-state sounds for myriad textures and tones
  • Unlock the potential of your mic locker with a powerfully versatile preamp
  • Easily track guitar, bass, or keyboards with the front panel 1/4“ Hi-Z instrument input

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.
