## Overview

The Universal Audio 710 Twin-Finity is a hybrid microphone preamp combining a 310V Class-A tube stage with a solid-state trans impedance amplifier. It features continuously variable tone blending, dual gain stages for versatile coloration, and a discrete ultra-high impedance JFET DI input ideal for guitars and basses. Housed in a durable stainless steel 2U half-rack unit, it offers professional-grade metering and build quality, making it a top choice for audio pros seeking infinite tonal possibilities.

## Description

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.

Review: From Malasya - In photo (desertcart) show the device is from California, but when it arrived at my home, it was from Malasya. I am worry about the quality.
Review: UA for voice over - There it is in action. Love the blend ability. I can change mics and blend as much tube as I need. I can go from a book on Audible to a trailer for a video game in minutes without changing the audio chain. Very clean sound.

*by S***R on November 15, 2016*

Pros: 1) genius concept for blending transistor and tube. 2) the di input is good for musicians with instruments 3) the panel design is clean and cool 4) the preamp is adequate for normal usage 5) sound seems smoother and silky with tube while crystal with transistor mode. I am not sure if it is mind implications or not. But my ears tell the feel about the difference is subtle but feelable. Cons: 1) the desktop handle mount is not standard accessory. While the included rack mount is almost useless at lease for me. I rather make it desktop 2) the noobs are truly plastic feel, although it is engineering taste but lack of solid construction.
