Universal Audio 4-710d Four Channel Tone-Blending Mic Preamp with Dynamics
Four Channels of Tone-Blending “Twin-Finity” Preamps and 1176-Style Compression with Built-In A/D ConvertersThe 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
