Four Twin-Finity preamps + 1176-style compression + 8 channels of A/D conversion. The Universal Audio 4-710d is the most flexible preamp in the UA lineup — four 710 Twin-Finity tube/solid-state tone-blending preamps, true-bypass 1176-style compression on each, plus eight channels of 24-bit A/D conversion for direct integration with any audio interface.

At a Glance

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.
• 2U Rackmount — All-metal chassis.

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.

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

What does Hemisphere Modeling do?

Hemisphere puts professional emulations of classic studio microphones inside the mic, so a single affordable mic can sound like several legendary models. You can audition and change the model to match the source.

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.

Your purchase includes: 4-710d Four-Channel Tone-Blending Mic Preamp (2U rackmount), IEC power cable, 1-year limited warranty.
