Universal Audio VOLT 4 MAX USB Audio Interface
The Volt 4 Max is a 12-in / 6-out desktop USB audio interface built around 32-bit / 192 kHz conversion and two onboard Tone Shaping preamps with Warmth, Focus, and Shine harmonic modes. Max Processing adds six real-time compression presets modelled on the 1176 and LA-2A, while a full-colour Smart Display, Auto-Gain, and Clip Protection keep tracking fast. ADAT/S/PDIF expansion, MIDI In/Out, and an onboard USB hub turn it into a compact control room for project studios.
- Two Tone Shaping mic preamps with 60 dB gain and three harmonic modes (Warmth, Focus, Shine) for tube, solid-state, and British Class-A colour
- Max Processing — six onboard compression presets tuned for vocals, guitars, and bass, modelled on the 1176 and LA-2A
- 32-bit / 192 kHz A/D–D/A conversion with 119 dB dynamic range on mic inputs and 126 dB on monitor outputs
- Main and Alt speaker switching, built-in talkback mic, two headphone outputs, ADAT/S/PDIF expansion, MIDI In/Out, and a USB hub
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.
- Monitor Outputs: 2 stereo pairs (Main and Alt), 1/4" TRS, 126 dB dynamic range
- Headphone Outputs: 2 × stereo (1/4" and 1/8" TRS), 45 mW into 32 Ω
- Smart Features: Smart Display, Auto-Gain, Clip Protection, talkback mic
Number of Channels: 12
This product offers 12 channels, allowing you to efficiently connect and manage multiple audio sources simultaneously. Each channel operates independently, giving you full control over each input, greatly expanding your ability to create and edit sound.
Number of Preamps: 2
The product features two preamplifiers, ensuring high-quality sound processing for two input channels. This system provides clear sound with low noise, ideal for stereo recording or using two microphones or instruments simultaneously.
Phantom Power: Yes
Phantom power provides the necessary voltage for condenser microphones that require an external power source to operate properly. This power supply is built directly into the microphone input, eliminating the need for additional power supplies.
Bit Depth: 32 bit
The 32-bit depth provides an extremely wide dynamic range and extreme precision in audio processing. This format is ideal for professional recording, post-production and sound design, where it is essential to capture every detail with maximum precision and minimum noise. 32-bit depth ensures the highest possible quality, which is especially important when processing highly dynamic audio.
S/PDIF: Yes
S/PDIF is a digital interface used to transfer high-quality audio between devices such as CD players, audio interfaces, amplifiers, and home theaters. It transfers audio signals in digital form without any loss of quality. S/PDIF ensures clean and accurate signal transmission without the need for conversion to analog form, minimizing noise and interference, making it ideal for professional and home audio systems.
ADAT: Yes
ADAT is a digital transmission protocol that allows the transmission of up to 8 channels of digital audio over a single optical cable (Toslink). It is often used in studio applications to increase the number of audio channels between devices such as audio interfaces and digital mixers. ADAT allows for high-quality audio transmission while providing more channels at lower sample rates. This format is ideal for situations where it is necessary to transmit multiple channels of digital audio without loss of quality.

DA Conversion: Yes
DA conversion allows digital signals to be converted to analog signals with high accuracy. This process ensures that digital audio is reproduced with minimal distortion, preserving all the fine details and dynamics of the original sound. Thanks to high-quality DA conversion, the sound is clear, rich, and true to the original when played through speakers or headphones.
AD Conversion: Yes
High-quality AD conversion ensures that every detail and dynamic range of analog audio is preserved when converted to digital form, ideal for professional recording and production. This allows analog sound sources such as microphones and instruments to be accurately recorded in digital systems.
