Buy a new UA 4-710d Tone-Blending Mic Preamp and get a UAD-2 QUAD DSP Accelerator FREE!
Now You Can:
  • Track through meticulously designed UA mic 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
  • Process signals via Send and Return jacks for each channel
Bring your mic collection to life with 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.

    4-710d Happiness...! "Ordering another one TODAY"
    by D. Taylor(Monday 26 September, 2016)

    The UAD 4-710d Mic Preamp is by far the best Mic Pre available to date (in my honest opinion).

    Have had mine for about 2 weeks now and I am quite impressed with the significant improvement of my tracks using it. Love to multiple inputs which supports a variety of configurations since I often have to change-up inputs on the fly based on who I am having come in to record. The quality… Read More

    Solid/Tube Pres + 8 channels of great A/D = must own
    by D. Chan(Tuesday 13 September, 2016)

    I originally purchased this due to the great promotion with the Quad Satellite, but after using it for a month, I would happily purchase it full price with no promotions. Everything works great, and the ability to connect it to my Apollo Twin using ADAT and adding up to 8 additional… Read More
