Universal Audio 710

Twin-Finity Tone-Blending Mic Pre & DI

Order Code: 710
RRP: $1,899.00

Dial up a sound - your sound - with the exact tones you've been searching for. The Twin-Finity™ uses a clever blend switch to allow either 100% valve, full solid-state, or anywhere in between.

"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."

The 710, although compact (half-rack) width, is full of nice features. It's a mic preamp, and there is also a front-panel DI socket, which is divine for bass tones.

The Twin-Finity box includes a 19" rack-kit for mounting one or two units.
