By merging the best of UA’s classic analog design with smart modern features and workflow enhancements, the 4-710d is the most flexible microphone preamp in the UA lineup.
Featuring four high-end mic/line preamps with a unique tube/solid-state tone blending circuit, as well as classic 1176-style compression on each mic channel, the 4-710d also offers tons of digital I/O to expand your setup.
At the core of the 4-710d are four channels of tone-blending “Twin-Finity” mic preamps. Each channel offers 100% tube and 100% solid-state signal path, as well as the ability to continuously blend between the two circuits. This gives you tons of textures — from creamy to crunchy — and lets you dial in the perfect amount of tube grit or solid-state sheen.
