Universal audio 710 twin-finity
The 710 Twin-Finity includes a 19" rack-kit for mounting one or two units. Guitar and bass players will especially appreciate the 710s ability to bring out the best of both active and passive pickups. Plus, the discrete JFET DI input circuit can also easily handle any electric instrument. Versatility makes the 710 the perfect preamp partner for any mic collection. The VU meter features a unique "Drive" mode allowing you to see how hard you are driving the input stage. 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. 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.
There are a number of bottlenecks in the circuit that are the root cause, some are places where design improvements can be made and other are limitations of performance as a result of the active and passive components in the design. 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 "∞". The Twin Finity 710 UA is a nice sounding preamp but in its price range isn’t the best performer out there. 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. There are lots of sensibly priced solid-state and tube preamplifiers out there, but the 710 is the only one that offers the best of both worlds - as well as everything in-between - all in one box, and within reach of any serious project studio’s budget.

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 710 was created specifically to add the tonal versatility and sonic inspiration missing from generic audio interface preamps. Thank you for purchasing the Model 710 Twin-Finity Mic/Line/Hi-Z Preamplifier a radically new UA pre-amp design which 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 award-winning 710 Twin-Finity™ 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.

Phantom power, low pass filter and a polarity flip switch add full functionality to a versatile preamplifier. The VU meter can switch between displaying standard output levels and a "Drive" mode that allows for seeing how hard the input stage is being driven. The discrete JFET DI input circuit can handle virtually any electric instrument, including guitars and basses with both active and passive pickups. Along with the variable input and output controls, this design allows for an almost infinite range of tones to be dialed-in. Both stages are fed from a variable gain solid-state transimpedance input amplifier, and are summed to a single output according to the setting of the blend knob.
The tube circuit utilizes a 310V single ended, Class-A triode tube stage, which is phased aligned with a solid-state gain stage. A blend control allows the dialing-in of either circuit or a combination of both in varying degrees. The dual path design combines the "warmth" of a high-voltage vacuum tube design with the clarity of a solid-state circuit. The 710 Twin-Finity from Universal Audio is a single channel, dual path microphone preamplifier that includes an instrument direct inject (DI) input.
