Universal Audio 710 Twin-Finity Tone-Blending Mic Preamplifier and DI Box
The 710 Twin-Finity runs two preamp circuits at once: a 310 volt Class A tube path and a transimpedance solid-state path, phase-aligned so a single Blend control moves between them without cancellation. Turned one way it is clean and fast, the other way it is compressed and crunchy, and every point in between is usable.
It offers more than 70 dB of gain with +48V phantom, a -15 dB pad, phase invert and a 75 Hz low cut, plus a discrete JFET DI with 2.2 Mohm input impedance on the front panel that switches in automatically on jack detect. Backlit VU metering shows output and Drive, and a 19 inch rack kit is included.
