4 hybrid tube/solid state preamps and 1176-style compressors in a single unit.

The Universal Audio 4-710d is a boutique quality, 4-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 multichannel preamp offers selectable 1176-style compression circuitry on each channel, plus four additional line inputs feeding 8 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.

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


  • 4 TEC Award-winning 710 Twin-Finity microphone/line preamps, each featuring:
  • Dual-path 285-volt Class-A tube and transimpedance solid state preamps
  • Phase-aligned tone-blending of tube and solid state circuits, creamy to crunchy
  • Newly designed 1176-style compression circuit per preamp channel
  • JFET Direct Input with 2.2MÎ ultra Hi-Z impedance w/auto input override
  • Large backlit VU meters for flexible metering of input drive, gain level, and gain reduction
  • Balanced send/return inserts (half-normalled)
  • 48V phantom power
  • 75Hz low cut filter
  • Polarity switch
  • Monolithic balanced output stage
Analog-to-Digital Conversion
  • 8 channels of high quality 24-bit A/D conversion:
  • Selectable sample rates up to 192kHz
  • Digital output via dual ADAT optical and AES/EBU DB-25 connectors
  • 8-channel soft limiter (switchable for all channels)
