Overview

4-710d Four-Channel Tone-Blending Mic Preamp w/ Dynamics

Four Channels of Tone-Blending “Twin-Finity” Preamps and 1176-Style Compression with Built-In A/D Converters

The Universal Audio 4-710d is a boutique quality, four-channel microphone/line preamplifier with unique tube and solid-state tone blending capabilities — perfect for a wide range of microphone and instrument sources. This versatile multi-channel preamp offers selectable 1176-style compression circuitry on each channel, plus four additional line inputs feeding eight channels of pristine analog-to-digital conversion. Building upon UA’s classic analog design approach, combined with smart modern features, the 4-710d is the most flexible preamp in the UA lineup.

At the core of the 4-710d are four channels of tone-blending “Twin-Finity” mic preamps with true-bypass 1176-style compression, including specially tuned "fast" and "slow" settings. Each of the four mic preamp channels allows for continuously variable phase-aligned tone, between a 100% tube and 100% solid-state signal path. Send and return jacks are available for external processing or signal access.

  • Four TEC Award-winning 710 Twin-Finity™ microphone/line preamps, each featuring:
  • Phase-aligned tone-blending of tube and solid state circuits, creamy to crunchy
  • Newly designed 1176-style compression circuit per preamp channel
  • Backed by 1-Year limited warranty

View All Features

The eight analog inputs are digitized via ultra high-quality 24-bit A/D converters at selectable sample rates up to 192 kHz. Digital output is available via dual ADAT “lightpipe” or AES/EBU DB-25 connectors, facilitating integration with most popular audio interfaces.

    Rik Simpson

    (Coldplay)

    "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."

    Versatile
    by b. driggers(Wednesday 4 March, 2015)

    I picked it up used out of Nashville used and, I will be purchasing another as, I complete my gear acquisitions for the studio I'm building. I wired it into the signal path using an Apollo Twin into Cubase. Set up was easy and, intergration was seamless and hassle free. I demoed it by… Read More

    yes, but
    by J. Gridl(Saturday 14 February, 2015)

    why does the apollo (dual/quad, not 16) not have an AES/EBU port?? I mean seriously, this would make 100% sense and they would sell A LOT more Apollo/4-710D Combo Packages... It's just stupid... sorry. ADAT is not "the same". One star off for "made in china" - it does… Read More

    Nothing New to Report. It\'s Excellent
    by J. May (Wednesday 21 January, 2015)

    Sometimes the skies part, a beam of light comes down, and a great piece of gear lands at your feet. Or, you go to a website and order it. Either way, most will be thrilled with the 4-710d. You're just not going to find a group of four preamps that sound this good at this price. Beyond that,… Read More
