Give a growing studio the routing, tone and hands-on control to move from a quick overdub to a larger production without rebuilding the recording setup. The Universal Audio Volt 4 Max 12-in/6-out USB audio interface combines two Tone Shaping Preamps, six-preset Max dynamics processing and 32-bit/192kHz conversion with four analog inputs, ADAT or S/PDIF expansion and MIDI I/O. Three harmonic character modes—Warmth, Focus and Shine—provide Tube, Solid State and British Class-A-inspired character, while Max compression adds tracking-ready dynamics modeled on classic 1176 and LA-2A processors. A full-color Smart Display, Auto-Gain and Clip Protection simplify level setting, while Main/Alt speaker switching, two headphone outputs and built-in talkback strengthen the monitoring workflow. Add loopback, an onboard USB hub and UAD Console and LUNA integration, and Volt 4 Max becomes a flexible desktop centerpiece for recording, mixing, collaboration and content creation.
Tone Shaping and Max Compression Create 18 Character Combinations
Two digitally controlled microphone preamps provide 60dB of gain with three selectable harmonic character modes for shaping vocals and instruments before they reach the DAW. Warmth introduces Tube-inspired color, Focus delivers a Solid State-style response, and Shine adds British Class-A-inspired presence. Max processing complements those preamp modes with six push-button compression presets designed for vocals, guitars and bass, with dynamics inspired by Universal Audio's classic 1176 and LA-2A processors. Combining the three Tone modes with the six Max settings provides 18 sonic starting points, allowing engineers to move quickly between subtle analog-inspired enhancement and more assertive tracking tones.
Smart Display and Studio Monitoring Keep Sessions Moving
The full-color Smart Display provides immediate feedback for input levels, settings and gain reduction, keeping essential information visible without relying on a computer screen. Auto-Gain establishes recording levels quickly, while Clip Protection helps manage unexpected peaks that could otherwise compromise a performance. Two studio-quality headphone outputs share a cue mix for monitoring and collaboration, and the built-in talkback microphone provides direct communication with performers. Main and Alt stereo monitor outputs add speaker switching for comparing a mix across two sets of monitors, while UAD Console and LUNA integration supports session recall and low-latency cue mixing.
ADAT MIDI and Analog I/O Give the Studio Room to Grow
Two mic/line inputs with front-panel Hi-Z instrument connections cover microphones, guitars, bass and other primary sources, while two additional line inputs accommodate synthesizers, drum machines and external studio gear. Optical ADAT provides up to eight additional inputs at 44.1/48kHz, with S/MUX supporting four channels at 96kHz or two at 192kHz; the optical connection can alternatively accept two-channel S/PDIF across supported sample rates. MIDI In and Out connect controllers, keyboards and synths, while an onboard USB hub accommodates peripherals and can power compatible external MIDI controllers. Independent 48V phantom power on the microphone channels further expands source flexibility.
32-Bit Conversion Delivers Detail From Tracking Through Playback
Volt 4 Max supports 32-bit conversion at sample rates up to 192kHz, providing high-resolution capture for vocals, acoustic instruments, electronic sources and expanded multichannel sessions. The microphone and line inputs provide 119dB A-weighted dynamic range, while the balanced monitor and line outputs reach 126dB with a maximum level of +20.2dBu. USB bus power supports mobile operation with compatible devices, and a dedicated external power input with the required supply included provides another option for studio setups. Built-in loopback can blend live sources with computer audio for podcasts, livestreams and video calls, extending the interface beyond traditional music production.
UAD Plug-Ins and LUNA Complete the Production Workflow
The included UAD Volt Studio Bundle pairs the interface with LUNA Digital Audio Workstation and more than 15 UAD plug-ins and instruments, including the UA 610 Tube Preamp & EQ Collection, Century Tube Channel Strip, Teletronix LA-2A Tube Compressor, UA 1176 Classic FET Compressor, Pure Plate Reverb, Galaxy Tape Echo and Oxide Tape Recorder. PolyMAX and Anthem synths plus UAD guitar amps add creative sound sources, while software from Celemony, Plugin Alliance, UJAM, Splice and UVI expands the package with pitch correction, bass processing, virtual drums, virtual bass and instruments, along with three months of FL Studio Producer Edition. Compatible with Mac, Windows, iPad and iPhone, the Universal Audio Volt 4 Max brings analog-inspired tracking tone, intelligent recording tools and expandable studio connectivity together in one desktop production system.
