Universal Audio 710 Twin-Finity™ Mic/Line Preamp & DI
The award-winning UA 710 Twin-Finity™ delivers the warmth of tubes and the clarity of solid-state in one versatile half-rack preamp. With continuously variable tone-blending between the 310V Class-A tube stage and solid-state transimpedance stage, the 710 lets you dial in anything from creamy saturation to crisp punch. Dual gain-stage controls and a unique VU “Drive” mode allow you to shape harmonic richness like a guitar amp, while its compact, rack-mountable design makes it a perfect studio or stage companion.
