Universal Audio 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.
