Universal Audio Volt 2 USB Audio Interface

Universal Audio Volt 2 — Desktop USB Audio Interface with Vintage 610 Preamp Character

The Universal Audio Volt 2 is a 2-in / 2-out USB audio interface that brings UA's classic 610 tube preamp character into a compact, bus-powered recording hub. With two combo XLR/TRS inputs, Vintage Mic Preamp mode, and 24-bit / 192 kHz conversion, it captures vocals, guitars, and instruments with studio-grade clarity. The Volt 2 suits creators who want clean recording with optional analog-style coloration at the press of a button.

Vintage Mic Preamp Mode and Class-Compliant USB-C Design

What sets this interface apart from other units in its segment is its onboard Vintage Mic Preamp mode — an all-analog circuit emulating UA's iconic 610 tube preamp. Direct Monitoring offers latency-free recording in stereo or mono, while the bus-powered, class-compliant USB-C design runs from a single cable on Mac, Windows, iPad, and iPhone (iOS 14+) without needing a separate power supply.

Two Combo Inputs with 48V Phantom Power and Vintage Mode

The input stage centers on two combo XLR/TRS jacks accepting microphones, line-level instruments, and Hi-Z sources like electric guitars and basses. Each channel has its own gain knob and LED level meter, plus a global 48V phantom power switch with a soft-start ramp that prevents clicks and pops when engaging condenser microphones.

• Number of Preamps: 2 — independent gain control per channel for stereo or dual-source recording sessions
• Phantom Power: Yes (48V) — soft-start ramp protects connected condenser microphones from power-on pops
• Inputs: MIDI IN, MIC/Line (2× combo XLR/TRS) — connect synths, drum machines, microphones, and instruments simultaneously

24-bit / 192 kHz Conversion with 111.9 dB Dynamic Range

Conversion runs through a Cirrus Logic CS4272 DAC/ADC chipset, delivering 24-bit / 192 kHz resolution across all inputs and outputs. Independent measurements confirm 111.9 dB dynamic range on the microphone inputs and -129 dBuA equivalent input noise — putting the Volt 2 among the better-performing interfaces in its segment.

• Sample Rate: 192 kHz / 24-bit — captures every nuance of vocal and instrument performances at studio-grade resolution
• Dynamic Range (Mic Input): 111.9 dB — ample headroom for clean, low-noise recordings across the audible spectrum
• Equivalent Input Noise: -129 dBuA (A-weighted) — quiet enough for low-output dynamic microphones without an inline preamp

Headphone Amplifier, Monitor Outputs, and Included DAW + Plug-ins

Two balanced TRS monitor outputs deliver +13 dBV professional line-level signal, paired with a dedicated 1/4" TRS headphone jack and its own volume knob. The package includes LUNA DAW, Ableton Live Lite, Melodyne Essential, and UAD plug-ins — UA 610, 1176, Teletronix LA-2A, Pure Plate Reverb, PolyMAX Synth — so recording can begin the moment the interface is unboxed.

• Outputs: MIDI OUT, Monitor OUT (2× balanced TRS), Headphone Jack 6.3 mm TRS — covers monitoring, MIDI, and private listening from a single desktop unit
• Package Content: Ableton Live Lite, Manual, Software bundle, USB-C to USB-A cable — everything needed to start recording on Mac, PC, or iOS
• Headphone Output: Yes — dedicated amplifier with enough power to drive most high-impedance studio headphones cleanly
