Overview
The 4-710d takes four of UA's TEC Award-winning 710 Twin-Finity preamps and bundles them with 1176-style compression and pristine A/D conversion in a single 2U rack unit — and costs less than three standalone 710 units. For engineers tracking bands or drum kits through tube/solid-state preamps with onboard dynamics, the 4-710d is one of the most cost-effective ways to build a four-channel premium analog front end.
Key Features
- Four TEC Award-Winning 710 Twin-Finity Preamps — Each with continuously variable tube/solid-state tone blending.
- Dual-Path Design Per Channel — 285V Class A tube + transimpedance solid-state, phase-aligned.
- 1176-Style Compression Per Channel — True-bypass; specially tuned "fast" and "slow" settings; same circuit topology as the famous 1176 limiter.
- JFET Direct Input on Each Channel — 2.2 MΩ ultra Hi-Z impedance with auto input override.
- 8-Channel 24-Bit A/D Conversion — Up to 192 kHz sample rate; the four preamp channels plus four additional analog line inputs.
- Digital Output — Dual ADAT optical or AES/EBU via DB-25 connector.
- Send/Return Jacks — Insert external processing between preamp and compressor stages.
- Low-Jitter Word Clock I/O — Sync with external clock sources.

Use Cases
- Drum Kit Tracking — Four preamps for kick, snare, and two overheads (combined with two more preamps elsewhere for toms).
- Small Ensemble Recording — Singer-songwriter with guitar, bass, vocals, and harmony.
- Front End for Apollo Interface — Add eight more A/D channels via ADAT to a Twin X or Solo.
- Voiceover / Podcast Multi-Host — Four mic channels with per-channel compression.
- Mobile / Location Recording — Compact 2U package for portable tracking.
Tone Blending Across Four Channels
Each channel has its own tone-blending control, so you can record drums with different tube/solid-state blends per source — fast solid-state on kick beater, blended tube warmth on snare top, full tube saturation on room mics. The flexibility this affords for tracking is unique in the under-$2K preamp market.

Frequently Asked Questions

Is this good for podcasting, streaming, and home studios?
Yes. These mics are built for vocals, podcasting, streaming, and project-studio recording, giving home creators access to pro mic tones without a full mic locker.
Does it need phantom power?
Condenser models need +48V phantom power. Dynamic models do not, though the modeling features work best with adequate clean gain.
