Bring your Mic Collection to Life with a Wide Range of UA Preamp Tones

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 paths, as well as the ability to continuously blend between the two circuits. This gives you a wide range of textures — from creamy to crunchy — and lets you dial in the perfect amount of tube grit or solid-state sheen.

A Legendary Compression Circuit

Each of the 4-710d’s four channels features true-bypass 1176-style compression, including specially tuned "fast" and "slow" settings. This enables quick, on-the-fly adjustments for fattening up a vocal, holding a bass guitar in place, or adding sizzle and texture to synths and horns.

Add Inputs and Professional A/D Conversion

With eight analog inputs, the 4-710d is perfect for expanding your studio. Digitized via ultra high-quality 24-bit A/D converters at selectable sample rates up to 192 kHz, the 4-710d easily connects to most interfaces with its dual ADAT optical or AES/EBU DB-25 connectors.
