Universal Audio Volt 476P USB Audio Interface

Universal Audio Volt 476P — Bus-Powered USB-C Interface with Built-In Analog Compression

This model is a desktop 4-in/4-out USB-C audio interface that brings Universal Audio's decades of analog heritage into a compact, bus-powered unit. Four onboard preamps, a real analog FET compressor, and 24-bit/192 kHz conversion make the Volt 476P a serious recording front-end for project studios, mobile rigs, and podcast setups. It is the right choice for creators who want genuine UA analog character — not a plug-in imitation — built directly into the hardware signal path.

Standout Features: Vintage Preamp Mode and the 76 Compressor

What separates this interface from every other bus-powered unit in this segment is its pair of dedicated analog circuits. The Vintage Preamp Mode engages an all-analog 610-style tube preamp emulation on every channel, adding tubelike dynamic saturation and harmonic weight to vocals, guitars, and bass. The onboard 76 Compressor is a real analog FET circuit inspired by UA's iconic 1176, with three hardware presets — VOC, GTR, and FAST — that cycle at the push of a button, so users get instant pro-studio compression without menu-diving.

Conversion and Signal Path — Pro-Grade Specs in a Desktop Box

The conversion stage is the foundation of any recording chain, and the gear delivers class-leading AD/DA performance at the maximum resolution supported by today's DAWs. This ensures true-to-life detail, dimensionality, and headroom on every track.

• Sample Rate / Bit Depth: 192 kHz / 24-bit — captures full-range detail for tracking and mixing
• AD/DA Conversion: Yes (class-leading analog circuitry) — preserves transient and harmonic information
• Number of Preamps: 4 — record a full band or multi-mic drum setup from a single unit
• With 48 V phantom power, it drives any condenser microphone found in your studio locker.

I/O, Monitoring, and MIDI — Built for Real Sessions

Beyond the preamps and compressor, this hardware is wired for flexible session work, with enough analog outputs to feed a small monitor rig, two independent cue mixes for collaborators, and a dedicated MIDI port for hardware synths and controllers.

• Inputs: 4 combo XLR/Jack + MIDI IN — accepts mics, instruments, and line-level sources
• Outputs: 6 × 6.3 mm TRS Jack + MIDI OUT — supports multiple monitor pairs or outboard gear
• Headphone Outputs: 2 × 6.3 mm TRS — independent level controls for engineer and artist
• Performers hear themselves in real time thanks to latency-free hardware monitoring.

Connectivity, Power, and Bundled Software

Bus-powered USB-C operation means no wall wart is required for laptop or desktop recording, and class-compliant drivers keep setup simple across Mac, Windows, iPad, and iPhone. Included software turns the unit into a complete recording studio out of the box.
