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.
NOW YOU CAN:
Track through meticulously designed UA tube preamp circuitry
Blend tube and solid-state textures for tons of flexibility
Harness classic 1176-style compression on each mic channel
Add 8 inputs to any Apollo interface via ADAT optical connection
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 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.
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 tweaking for fattening up a vocal, hold a bass guitar in place, or for 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.
