Universal Audio 710 Twin-Finity – Tube/Solid-State Mic Preamp & DI
The 710 Twin-Finity is a single-channel mic/line preamp and instrument DI with two signal paths. One is a 310V Class-A tube stage and the other is a solid-state transimpedance stage. A blend knob moves continuously between 100% tube and 100% solid state, so one preamp covers warm and thick, fast and clean, and everything in between. It makes a solid upgrade over interface preamps for vocals, acoustic instruments, and DI’d guitar, bass, and keys.
Like other UA preamps, it has separate Gain and Level controls, so you can push the input stage for color and distortion and then set the output level independently. The VU meter has a Drive mode that shows how hard the input stage is being hit.
