From the seller
Universal Audio 4-710d Four-Channel Tone-Blending Mic Preamp & Dynamics Processor
£1200
Kept exclusively in a smoke-free, climate-controlled professional London voice recording studio. Rack-mounted since day one, this unit has been meticulously cared for and driven strictly within balanced studio signal paths.
The 4-710d combines four channels of UA's acclaimed Twin-Finity™ tone-blending preamps—allowing you to blend seamlessly between 100% solid-state speed and 100% tube warmth—with classic 1176-style compression on every channel and premium 24-bit/192kHz A/D conversion.
Key Features & Specs
4 Preamps with Twin-Finity™ Tone Blending: Continuously phase-aligned variable blending between 100% 12AX7 tube warmth and 100% solid-state transimpedance circuit clarity.
1176-Style Compression: Newly designed 1176-style compression circuit on each channel with fast/slow attack and release settings.
Integrated 24-Bit / 192kHz A/D Conversion: Premium digital conversion via dual ADAT optical outputs and AES/EBU DB-25 connector.
Hi-Z Instrument Inputs: 4 front-panel JFET instrument inputs for line sources and direct bass/guitar tracking.
8-Channel Digital Expansion: 4 additional line inputs feed the internal A/D converter directly, giving you an 8-channel A/D expander over ADAT.
Monitored Control: Individual backlit VU meters with selectable drive and output monitoring, switchable low-cut filters, phase invert, and 48V phantom power.
Condition & Usage
Usage: Used solely in a static professional studio environment—never gigged, toured, or exposed to harsh environments.
Functional Condition: 100% fully functional. Tubes are quiet, pots and switches are smooth and static-free, and all analog/digital inputs and outputs operate flawlessly.
Cosmetic Condition: Excellent overall condition with light rack rash on the ears consistent with normal studio installation (please refer to photos for detailed visual condition).
