Universal Audio 710 Twin-Finity Mic Pre & D.I.

What happens when you marry the clean, sterile sound of a class A FET transistor with the warm, loving tone of vacuum tubes? You get the Universal Audio 710 Twin-Finity™, a radically new Universal Audio pre-amp design which uniquely combines both the classic retro warmth of Universal Audio tube design and the transient bite of solid-state in a 2U, half-rack, all-metal chassis. The 710 was created specifically to add the tonal versatility and sonic inspiration missing from generic audio interface pre-amps. You can even rack 2 of them together for a stereo pair.
