Mic Preamp w/ Dynamics.

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.

    The 4-710d is one of the smartest mic preamps around. It’s cleverly designed and fun to use. I love the drive it gives me on drums and guitars.

    Chris Dugan

    (Green Day, Iggy Pop, U2)

    The 4-710d is a whole racks worth of gear in one small box. Four big-sounding mic pres, four 1176's, eight channels of A/D conversion — big UA warm sound.

    Rik Simpson

    (Coldplay, Portishead, Jay Z)

    "I've been using the [4-710d] on loads of different sources. It adds a real sense of depth and originality and I love how you can the control the harmonic distortion to fall anywhere between super clean to fuzzy and warm."

    It is a great blend of the clean and the soulful ways of the sound. It compliments very well my Apollo and Apollo Twin set-up. I am using it slaved via WordClock as the ADAT sync proved a little unstable. The extra 4 line ins that can be also sent via ADAT ara a great addition. The blend… ǶÁÂȪむ
