Universal Audio Volt 4 Max

A Volt designed to take studio creativity further

The Volt 4 Max takes a modern approach to the desktop USB audio interface: delivering serious recording quality, flexible enough connectivity to accommodate multiple sources, and processing tools that sound musical right away. It is aimed at creators who want to go beyond simple audio conversion and have a true central hub for their recordings.

This Max version places particular emphasis on shaping the sound at the source. Its integrated processing quickly delivers more present vocals, more consistent guitars, or better-controlled bass, while maintaining a direct and reassuring user experience every day.

For musicians, beatmakers, and creators who want to record without complications

With its two microphone preamps, front-panel Hi-Z instrument inputs, and line inputs, the Volt 4 Max is equally suited to the singer-songwriter recording vocals and guitar and the hybrid producer working with synthesizers, drum machines, and external processors. The two microphone inputs feature independently switchable phantom power: a valuable advantage when using two condenser microphones or combining a condenser microphone with a dynamic microphone.

Compatible with the leading DAWs, including Ableton Live, FL Studio, GarageBand, Logic Pro, and Pro Tools, this audio interface naturally fits into a Mac or PC setup. Its maximum sample rate of 192 kHz meets the demands of production, podcasting, music streaming, and high-definition recording projects.

Expressive preamps and Max processing ready for recording

60 dB of gain and controlled recording

The two microphone preamps offer up to 60 dB of gain with digital control. This reserve makes it possible to precisely adjust the level to suit the microphones and recorded sources, including those that require more gain. The Auto-Gain function speeds up recording setup, while the anti-clipping protection helps prevent accidental digital distortion.

The central color Smart Display brings together essential information: current settings, signal levels, and gain reduction applied by the processing. This gives users a clear view of the recording chain without having to interrupt their creative flow.

Tone Shaping and compression: a configurable sonic signature

The Tone Shaping function offers three complementary modes: Warmth to add density and gentle harmonic saturation, Focus to enhance definition, and Shine to open up the top end. These colors make it easy to quickly adapt the character of a recording to vocals, electric guitar, acoustic guitar, or bass.

The integrated Max processor adds six compression presets dedicated to vocals, guitar, and bass. Its processing is inspired by LA-2A- and 1176-style compressors, two approaches renowned for their musicality: one smoother and more gradual, the other faster and more energetic. With more than 18 Tone and Max combinations, the Volt 4 Max makes it easy to create a sound that is already shaped before even opening any plug-ins.

Connectivity suited to instruments and external hardware

The front-panel instrument inputs 1 and 2 directly accommodate guitar, bass, or any high-impedance instrument. The XLR / jack combo inputs allow microphones and line-level signals to be connected, while line inputs 3 and 4 expand the possibilities for keyboards, expanders, drum machines, or external preamps. This layout makes the interface particularly well suited to a compact studio designed to grow over time.
