Universal Audio 710 Twin-Finity Microphone Preamp

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. The key to its sonic flexibility lies in its innovative circuit design, featuring a solid-state trans impedance 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 trans impedance stage is controlled via the "Blend Knob" labeled "∞". Like all Universal Audio 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. Versatility makes the 710 the perfect preamp partner for any mic collection. Plus, the discrete JFET DI input circuit can also easily handle any electric instrument. Guitar and bass players will especially appreciate the 710s ability to bring out the best of both active and passive pickups. The 710 Twin-Finity includes a 19" rack-kit for mounting one or two units.
