The Universal Audio Volt 4 Gen 2 is the USB audio interface in the Volt series with the most extensive input options: four Tone Shaping preamps, MIDI for controllers and synths, and an ADAT input for adding up to eight channels. Designed by the same team behind the Apollo interfaces, it combines simple, intuitive control—with Smart Display, Auto-Gain, and Clip Protection—with 32-bit converters that preserve every detail. It sets up in minutes on Mac, Windows, iPad, and iPhone and comes with a suite of UAD plug-ins and the LUNA DAW, ready for your home studio and a setup that’s bound to grow.

Four Tone-Shaping Preamps with Warmth, Focus, and Shine Modes

Each of the Volt 4’s four microphone preamps offers three tone-shaping modes: Warmth adds the warmth of a tube preamp, Focus the clarity of a solid-state preamp, and Shine the openness of a British-style Class-A preamp. Choose the character of your recording right from the start, whether for vocals, guitars, or any other source.

Four Mic/Line/Hi-Z inputs for vocals and instruments

The four professional-grade Mic/Line inputs, with clean 48 V phantom power, power your studio condenser microphones and also accommodate high-impedance guitars and basses. You can record vocals and instruments simultaneously—for example, a band in a rehearsal room or multiple microphones on the same source.

ADAT and MIDI to expand your studio

The ADAT input lets you add up to eight channels by connecting an external multichannel preamp: when your needs grow—for example, to mic a full drum kit—you don’t have to switch interfaces. The built-in MIDI connects directly to controllers and synths, eliminating the need for a separate MIDI interface.

Smart Display, Auto-Gain, and Clip Protection

The color Smart Display shows detailed information about inputs, levels, and settings. Auto-Gain sets the ideal recording level in seconds, and Clip Protection handles unexpected peaks, so you can focus on your performance instead of the meters.

32-bit Conversion, Loopback, and USB Power

The 32-bit/192 kHz converters capture every detail, and the powerful, clean monitor and headphone outputs guide you from the first take to the final mix. The Loopback feature lets you mix live sources with audio from your computer for podcasts, livestreams, and video calls.

Class-compliant on Mac, Windows, iPad, and iPhone

Volt 4 is USB-bus-powered, requiring no external power supplies, and is class-compliant on Mac, Windows, iPad, and iPhone: it works with any DAW without installing drivers. On Windows, the ASIO driver is available via the UA Connect app, while on iPhones and iPads without a USB-C port, you’ll need the Apple Lightning to USB Camera Adapter.

UAD Plug-ins and LUNA DAW Included

Each Volt includes over 15 UAD plug-ins and virtual instruments, including EQs, compressors, synths, and guitar amp simulations—the same software used for decades in professional production—along with LUNA, Universal Audio’s DAW designed to make recording quick and easy.
