The Universal Audio Volt 4 Gen 2 is a 12-in/6-out USB audio interface built by the same engineers behind the legendary Apollo line, and it brings genuine studio-grade recording to any desk, bedroom, or backstage corner. With Tone Shaping Preamps, full 32-bit/192 kHz conversion, and a built-in Smart Display, it gives musicians, podcasters, and producers a fast, reliable way to capture professional sound without needing a full studio setup.
Preamps That Do the Heavy Lifting
A thin, lifeless recording usually comes down to the preamp, not the performer. The Volt 4 Gen 2 fixes that with two Tone Shaping Preamps offering 60 dB of gain and three distinct character modes, so you can dial in the tone before you even hit record.
Three Classic Tone Modes: Warmth, Focus, and Shine recreate Tube, Solid State, and British Class-A preamp characteristics, giving every vocal or instrument take real depth and personality.
32-Bit/192 kHz Conversion: High-resolution audio conversion captures every detail of your performance with clarity that holds up from the first take to the final mix.
Auto-Gain and Clip Protection: Set levels automatically and avoid unexpected peaks, so you can focus on playing instead of watching meters.
Inputs Built for a Growing Setup
Most compact interfaces force you to choose between simplicity and flexibility. The Volt 4 Gen 2 doesn't make you pick. With expanded connectivity, it's built to grow alongside your setup, whether you're recording solo or running a full band session.
12-In/6-Out I/O: Two mic/line inputs and two front-panel Hi-Z instrument inputs let you record vocals and instruments at the same time without juggling cables.
ADAT or S/PDIF Expansion: Add up to eight more channels through optical input, giving you a clear path to scale your studio as your needs change.
MIDI In/Out and USB Hub: Connect keyboards, drum machines, and controllers directly, with the onboard hub able to power external MIDI gear too.
A Studio That Fits in Your Bag
Great gear shouldn't require a power outlet, a rack, or a moving truck. The Volt 4 Gen 2 is bus-powered and class-compliant, so it works the moment you plug it in, whether you're at a desk, on a tour bus, or recording in a hotel room between shows.
USB Bus-Powered: No external power supply needed, making setup simple on Mac, Windows, iPad, and iPhone.
Built-In Loopback: Blend live input with computer audio for podcasts, livestreams, or video calls using the same technique pro broadcasters rely on.
Full Integration with UAD Console and LUNA: Get session recall and low-latency cue mixes, keeping your workflow smooth from tracking through mixdown.
One Interface, Every Session Covered
The Volt 4 Gen 2 is built for people who record often and don't want their gear getting in the way of their ideas. Between the Tone Shaping Preamps, expanded I/O, and bus-powered design, it covers tracking, mixing, podcasting, and livestreaming without asking you to compromise on sound quality. Add in a bundle of UAD plug-ins and the LUNA DAW, and you've got a setup that holds its own from the first idea to the finished track.
