Universal Audio Volt 4 Gen 2

A Second-Generation Volt Designed for the Hybrid Studio

The Volt 4 Gen 2 continues the legacy of Volt USB audio interfaces, taking a more ambitious approach to home studio work and hybrid production. It retains the range's direct, musical spirit while evolving its recording control, display and expansion capabilities.

This interface is aimed at musicians, producers and creators who do not want to be limited by a simple two-input setup. With 12 simultaneous inputs and 6 outputs, it can become the nerve center of a workstation bringing together microphones, synthesizers, drum machines, guitar, nearfield monitors and MIDI devices.

Record, Produce and Stream Without Interrupting Your Inspiration

The Volt 4 Gen 2 is equally suited to singer-songwriters recording demos and producers working with multiple line sources. The two combo inputs accommodate a dynamic microphone, condenser microphone or line source, while the front-panel Hi-Z instrument inputs let you connect a guitar or bass directly, without an external DI box.

Its operation also meets the needs of podcasting, streaming and content creation. The built-in loopback makes it easy to capture audio from a computer, for example to stream a session, record a call or incorporate a backing track into a live broadcast. The headphone output provides precise nearfield monitoring during recording.

LUNA and UAD Console users benefit from dedicated integration with session recall and low-latency headphone cue mixes. The aim is to maintain comfortable, responsive monitoring during recording, even in a project containing multiple tracks and virtual instruments.

Shapable Preamps and Connectivity Ready to Evolve

Three Preamp Character Options to Shape the Sound at the Source

The two Tone Shaping microphone preamps deliver up to 60 dB of gain, providing valuable headroom for vocals, acoustic guitars, amplifiers or microphones requiring more level. Their Warmth, Focus and Shine modes let you tailor the character of the recording to suit the source and the desired result.

Warmth provides a denser, warmer feel, useful for adding weight to a vocal or bass. Focus prioritizes definition and presence in the midrange, while Shine helps emphasize openness and detail in the highs. These three voicings make it easy to find a sonic direction quickly, even before opening up the processing in your audio software.

Confident Control During Recording

The color Smart Display provides a more immediate view of the interface's essential information. Combined with Auto-Gain and anti-clipping protection, it supports critical recording sessions by reducing guesswork during setup. Auto-Gain helps establish a consistent input level, while anti-clipping protection helps safeguard recordings when the performance becomes more dynamic.

Digital Expansion, MIDI and Flexible Monitoring

The ADAT- or S/PDIF-compatible optical input opens the door to a larger setup. You can add external preamps, bring in additional channels from a converter or integrate digital equipment into your studio. In ADAT mode, the interface supports up to 8 channels at 44.1 or 48 kHz.

The MIDI inputs and outputs on mini-jacks let you control a synthesizer, drum machine or hardware controller. The two additional USB-C ports make this audio interface even more practical: one serves as a USB host, while the other acts as a hub for connecting a compatible device. An external USB-C power supply can be used when your setup requires greater stability.
