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.

    Versatile & great value!
    by J. Bennett(Sunday 16 October, 2016)

    Love this unit! I have an Apollo 8p and grabbed this along with the bundled satellite unit offer at the time. Great price, and super flexible for using with inserts or adding in the 1176 compressor type circuit through any channel. I sometimes just record the effects back in on a printed… Read More

    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). After extensive research, I purchased the 4-710d and replaced my Apogee Mic Pre (a serious upgrade to my system). Words can’t explain the emotions that went through me after hearing what the 4-710d… Read More

    Great Choice!
    by P. Laraque(Wednesday 14 September, 2016)

    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
