Universal Audio Volt 4 Gen 2

The Universal Audio Volt 4 Gen 2 gives your recordings character and room to grow

The Universal Audio Volt 4 Gen 2 is a compact USB-C audio interface for vocals, guitar, keyboards, and content creation. Two Tone Shaping preamps offer 60 dB of gain and Warmth, Focus, and Shine sound modes, allowing you to shape the character of your source during recording. The 32-bit/192 kHz conversion captures your playing in detail, while Auto-Gain and Clip Protection help set and monitor your recording levels. The color display instantly shows the selected channels, meters, and settings. With additional line inputs, optical expansion, and MIDI, the interface is suitable for both a compact home studio and a larger recording setup. Loopback also makes it useful for streaming and podcasts. Through UAD Console and LUNA, you can manage monitoring and session settings, among other things. A clear interface that lets you start small without holding back your next step.

Connections and recording features

The Volt 4 Gen 2 offers up to 12 inputs and 6 outputs, including digital expansion. There are two XLR/TRS microphone/line inputs, two front-panel Hi-Z instrument connections, and two additional TRS line inputs. The Hi-Z connections share the first two recording channels and are not additional independent channels. Four analog line outputs, including a stereo monitor pair, and one stereo headphone output provide monitoring. The two microphone channels have individually switchable 48 V phantom power. Direct monitoring and built-in loopback are included. The optical TOSLINK input supports either ADAT or S/PDIF. ADAT supports eight channels at 44.1/48 kHz, four at 88.2/96 kHz, and two at 176.4/192 kHz; S/PDIF provides two channels. MIDI In and Out use 3.5 mm TRS Type A. The USB-C HOST connection operates according to USB 2.0, alongside a USB-C hub port for peripherals up to 5 V/0.5 A and a separate 5 V USB-C power input.

Power, size, and delivery

USB bus power is possible if the host provides sufficient power. If necessary, use a suitable external USB power supply via the separate 5 V input; a mains power supply is not included. A one-meter USB-C to USB-C cable is included. According to UA, the enclosure measures approximately 18.7 x 12.5 x 5.1 cm and weighs approximately 0.6 kg.
