The 710 Twin-Finity™ is a radically new UA pre-amp design which uniquely combines both the classic retro warmth of UA tube design and the transient bite of solid-state in a 2U, half-rack, all-metal chassis. The 710 was created specifically to add the tonal versatility and sonic inspiration missing from generic audio interface preamps.

The 710 was created specifically to add the tonal versatility and sonic inspiration missing from generic audio interface preamps. The key to its sonic flexibility lies in its innovative circuit design, featuring a solid-state transimpedance 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 transimpedance stage is controlled via the "Blend Knob" labeled "∞". Blending is continually variable between 100% tube and 100% solid-state offering a practically infinite range of unique pre-amp tones and the ability to easily dial-in your own signature sound. 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. 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 is designed and built at UA headquarters in California, and includes a 19" rack-kit for mounting one or two units.
