The Best of Two Tonal Worlds in One Great Pre/DI

Get to know them!

The Universal Audio 710 Twin-Finity mic preamp/DI gives you the best of tube and solid-state tones — and even lets you blend them together! The 710 houses a Class A FET mic preamp, as well as a Class A tube pre. A Tone Blending knob lets you take the 710 from solid-state "bite" to a classic tube circuit and lets you continuously blend them to nail your signature sound. The Twin-Finity's dual gain stage controls also let you crank up the gain and add tasty vintage-style coloration to your signal. At Sweetwater, we love to paint with sound, and the 710 Twin-Finity has an incredible sonic palette packed into its compact half-rack chassis.

Tube or solid-state: How about both?

The 710 Twin-Finity tube/solid-state tone-blending mic pre/DI is the first preamp ever to offer phase-aligned blending of discrete tube and solid-state circuits. This preamp can be 100% tube, 100% solid-state, or anything in between! Use the input gain to drive the Class A triode tube stage into creamy saturation, then dial in a little transient bite from the solid-state transimpedance circuit, or vice versa — or any combination you can dream up.

Innovative circuit design

The 710's innovative circuit design is the key to its sonic flexibility. A solid-state transimpedance input amp simultaneously drives separate phase-aligned tube and solid-state gain stages that are summed to a single output. You control the mix between the 310V single-ended Class A triode tube stage and solid-state transimpedance stage via the Trans-Tube blend knob, which offers continually variable blending between 100% tube and 100% solid-state, letting you easily dial in your own signature sound from an almost infinite spectrum of unique tones.

Classic UA controls and versatility

In classic UA fashion, 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 that allows you to see how hard you are driving the input stage. The discrete JFET DI input circuit can also easily handle any electric instrument. Guitar and bass players will especially appreciate the 710's 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.
