Universal Audio VOLT 4 MAX Interfaccia Audio USB

Universal Audio Volt 4 Max USB Audio Interface

The Universal Audio Volt 4 Max is a 12-in / 6-out desktop USB audio interface delivering 32-bit / 192 kHz conversion and two Tone Shaping preamps offering Warmth, Focus, and Shine harmonic modes. Max Processing layers six real-time compression presets on top, while Auto-Gain keeps tracking fast. ADAT/S/PDIF expansion, MIDI In/Out, and an onboard USB hub round out the package.

Standout Features

Most desktop interfaces stop at clean preamps. The Volt 4 Max adds three harmonic modes emulating tube, solid-state, and British Class-A circuitry, plus six compression presets modelled on the 1176 and LA-2A.

Conversion and Preamps

The Volt 4 Max records and plays back at up to 32-bit / 192 kHz. Two Tone Shaping mic preamps deliver 60 dB of gain with +48 V phantom power.

• A/D – D/A Conversion: 32-bit / 192 kHz
• Microphone Inputs: 2 × XLR/jack combo, 60 dB gain, 119 dB dynamic range
• Instrument Inputs: 2 × 1/4" TS Hi-Z, 1 MΩ

I/O and Expansion

Twelve inputs and six outputs cover tracking bands, layering hardware, and feeding two pairs of monitors. ADAT/S/PDIF optical input adds eight channels.

• Simultaneous I/O: 12 in / 6 out
• Digital Expansion: ADAT/S/PDIF, 8 ch @ 44.1/48 kHz, 4 @ 96 kHz, 2 @ 192 kHz
• MIDI and USB Hub: MIDI In/Out, USB 2.0 host + USB hub

Monitoring and Control

The Smart Display shows levels, settings, and gain reduction in full colour. Main and Alt speaker switching, a talkback mic, and two headphone outputs handle monitoring.
