Universal Audio 710 Twin-Finity Tone-Bending Mic Preamplifier Universal Audio

The Universal Audio 710 Twin-Finity is a hybrid mic preamp/DI that combines solid state and tube gain stages and the ability to variably blend the two, from fully solid state or tube and anything in between—includes a 19″ rack-kit for mounting one or two units.

 

The Universal Audio 710 Twin-Finity™ is a radical departure from Universal Audio’s classic preamp designs, which many come to expect of UA. However, UA also proved itself to be a company of innovation, some of which have spanned decades and have yet to be replaced. The award-winning 710 Twin-Finity is a testament to UA innovation. It combines both the classic retro warmth of tubes with the transient bite of solid-state circuitry. The 710 Twin-Finity’s ability to blend tube and solid-state tone 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. There are numerous affordable solid-state and tube preamplifiers in the world, but the 710 Twin-Finity is the only one that offers the best of both worlds—as well as everything in-between—all in one 2U, half-rack box that’s within reach of any serious project studio’s budget.

Universal Audio 710 Twin-Finity unique features:

• Harness the distinct sonic properties of tubes and solid-state in one unique preamp/DI
• Blend between tube and solid-state sounds for myriad textures and tones
• Unlock the potential of your mic locker with a powerfully versatile preamp
• Easily track guitar, bass, or keyboards with the front panel 1/4″ Hi-Z instrument input

Universal Audio 710 Twin-Finity—Under the Hood

The key to the 710 Twin-Finity’s 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 “∞”. 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.

The Universal Audio 710 Twin-Finity was specifically created to add the tonal versatility and sonic inspiration missing from the generic preamps found in most audio interfaces. Order yours today. For more information, call or chat online with your PAD Studio Consultant.
