Universal Audio Volt 4P Max: The Flagship Model with 4 Tone-Shaping Preamps
Are you looking for the ultimate desktop USB audio interface for recording full bands, multi-host podcasts, or multi-channel studio sessions? The Universal Audio Volt 4P Max is the absolute pinnacle of the Volt Max series. While other models offer select microphone inputs, the Volt 4P Max equips all four of its analog inputs with professional Tone Shaping preamps and Max Processing.
Combine this with superior 32-bit / 192 kHz audio conversion, a generous 12-in / 6-out I/O configuration with optical ADAT expandability, Main/Alt speaker switching, a built-in talkback microphone, and a crisp Smart Display. The Volt 4P Max transforms any room into a full-fledged professional recording studio.
Why Choose the Universal Audio Volt 4P Max?
1. Four Powerful Tone-Shaping Preamps (18 Tone Combinations per Channel)
Record up to four vocalists or instruments simultaneously with unmatched analog warmth. Each of the four microphone and line inputs features two unique hardware functions:
- 3 Tone Shaping Modes: Effortlessly switch per channel between Warmth (rich UA 610 tube sound), Focus (tight solid-state clarity), or Shine (airy, open British Class-A high-end).
- Max Processing Presets: Onboard analog dynamics processing with 6 optimized compressor presets for vocals, guitar, and bass (such as Rap Vocal, Album Vocal, Electric Guitar, and Tight Bass), based on the iconic 1176 and LA-2A hardware.
2. Superior 32-Bit / 192 kHz Audio Conversion
Capture every musical performance with the utmost precision. With a dynamic range of 119 dB on the inputs and 126 dB on the monitor outputs, your recordings remain noise-free, transparent, and dynamic—from the softest acoustic strumming to the loudest drum beats.
3. Maximum Expandability: 12-In / 6-Out I/O with ADAT
. Thanks to the four built-in analog preamps, you can record an entire band or multiple vocalists at once. Want to record drum kits with multiple microphones in the future? Using the optical ADAT/S/PDIF input, you can effortlessly add up to 8 additional digital channels to your setup.
4. Advanced Control Room Monitoring & Talkback
- Main / Alt Speaker Switching: Switch between two different sets of studio monitors with the push of a button to critically compare your mix across multiple systems.
- Built-in Talkback Microphone: Communicate directly and clearly with musicians or guests from the control room.
- Two Headphone Outputs: Features a 6.3mm TRS and a 3.5mm stereo jack with a dedicated cue mix for seamless collaboration during recording sessions.
5. Smart Display, Auto-Gain & Clip Protection
- Full-Color Smart Display: Get instant, clear visual feedback on input levels, channel selections, and the compressors’ real-time gain reduction.
- Auto-Gain & Clip Protection: Automatically adjust levels in seconds. Clip Protection prevents digital distortion during unexpected loud peaks.
- Loopback & Built-in USB Hub: Ideal for multi-channel livestreams and podcasts, plus a USB hub for directly connecting MIDI controllers or peripherals.
