The award-winning 710 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.
