Build a compact recording setup today without boxing yourself in when tomorrow's session gets bigger. The Universal Audio Volt 4 Gen 2 12-in/6-out USB audio interface combines two Tone Shaping Preamps, four analog inputs, ADAT or S/PDIF expansion, MIDI I/O and 32-bit/192kHz conversion in a bus-powered desktop design. Three preamp character modes—Warmth, Focus and Shine—provide Tube, Solid State and British Class-A-inspired tones at the recording stage, while front-panel Hi-Z instrument connections accommodate guitars, basses and other instruments. A full-color Smart Display keeps levels and settings visible, with Auto-Gain and Clip Protection helping streamline setup and safeguard dynamic performances. With additional line outputs for outboard processing, an onboard USB hub, loopback and UAD Console and LUNA integration, Volt 4 Gen 2 provides the connectivity to move from solo recording into more ambitious studio and content-production workflows.
Tone Shaping Preamps Add Character at the Source
Two digitally controlled mic/line preamps provide 60dB of gain and three selectable tonal personalities for shaping recordings before they reach the DAW. Warmth introduces Tube-inspired color, Focus provides a Solid State-style response, and Shine adds British Class-A-inspired presence, giving vocals and instruments distinct starting points without requiring an external preamp. Independent 48V phantom power on each channel supports compatible condenser microphones, while two front-panel Hi-Z connections make direct guitar and bass recording straightforward. Two additional line inputs expand the analog input count to four for synthesizers, drum machines and other line-level studio hardware.
Smart Display Auto-Gain and Clip Protection Speed Up Sessions
The full-color Smart Display provides at-a-glance feedback for inputs, levels and settings, helping musicians and engineers stay focused on the performance instead of navigating software windows. Auto-Gain establishes recording levels quickly when changing sources or performers, while Clip Protection helps catch unexpected peaks before they overload the digital recording path. Integration with the UAD Console app and LUNA adds session recall and low-latency cue mixing, providing additional control when sessions require more sophisticated monitoring and routing.
ADAT MIDI and Additional I/O Leave Room to Expand
Optical connectivity allows up to eight ADAT input channels at 44.1/48kHz, four channels at 96kHz or two channels at 192kHz using S/MUX, making it possible to add compatible external preamps and converters as recording requirements grow. The same optical connection can operate as a two-channel S/PDIF input across supported sample rates. MIDI In and Out integrate keyboards, controllers, synths and drum machines, while an onboard USB hub provides a convenient connection for peripherals and can supply power to compatible external MIDI controllers. In addition to the main stereo monitor pair, balanced line outputs 3–4 can accommodate outboard gear and more advanced routing configurations.
32-Bit Conversion Provides Detail From Input to Monitoring
Volt 4 Gen 2 records at resolutions up to 32-bit/192kHz, providing a high-resolution path for vocals, acoustic instruments, electronic sources and expanded multichannel sessions. The analog line inputs provide 119dB A-weighted dynamic range, while the microphone preamps deliver 118dB. Balanced monitor and line outputs reach 126dB of dynamic range and a maximum output level of +20.2dBu, supporting clear monitoring and studio-level signal routing. A dedicated 1/4" headphone output provides the cue mix for tracking and critical listening, while built-in loopback combines live inputs with computer playback for podcasts, livestreams and other content creation.
UAD Software Turns the Interface Into a Complete Production System
The included UAD Volt Studio Bundle pairs the hardware with LUNA Digital Audio Workstation and more than 15 UAD plug-ins and instruments, including the UA 610 Tube Preamp & EQ Collection, Century Tube Channel Strip, Teletronix LA-2A Tube Compressor, UA 1176 Classic FET Compressor, Pure Plate Reverb, Galaxy Tape Echo and Oxide Tape Recorder. PolyMAX and Anthem synths plus UAD guitar amps broaden the creative palette, while additional software from Celemony, Plugin Alliance, UJAM, Splice and UVI adds pitch correction, bass processing, virtual drums, virtual bass and instruments, along with three months of FL Studio Producer Edition. USB bus power and compatibility with Mac, Windows, iPad and iPhone make the Universal Audio Volt 4 Gen 2 USB-C Audio Interface a scalable production centerpiece that can move between mobile recording and an expanded desktop studio.
