The Universal Audio Volt 4P Max is the flagship model in the new Volt range, combining four full Tone Shaping mic preamps with onboard Max compression and expanded 12-in/6-out connectivity. It is built for bands, multi-mic recording, collaborative production and advanced content setups that need more analogue inputs without giving up UA’s fast, creator-friendly workflow.
Four Tone Shaping preamps
All four mic/line channels provide up to 60dB of digitally controlled gain and can use UA’s three Tone Shaping characters: Warmth for tube-inspired depth, Focus for controlled solid-state punch, and Shine for a more open British Class-A style sound. Independent 48V phantom power is available per channel.
Max Processing on a four-preamp interface
Max Processing adds six real-time compression presets tuned for vocals, guitars and bass, inspired by classic UA compressor designs including the 1176 and LA-2A. Combining Tone and Max gives you more than 18 source-shaping options, making it possible to commit to polished, musical sounds during tracking.
Built for larger sessions
Four rear mic/line combo inputs let you capture up to four microphone or line sources at once, while two front-panel Hi-Z inputs are ready for guitar and bass. ADAT or S/PDIF optical input allows digital expansion, including up to eight ADAT channels at 44.1/48kHz. MIDI In/Out connects controllers and synths, and the onboard USB hub can host a compatible peripheral.
Studio monitoring and communication
Main/Alt speaker switching lets you compare mixes across two monitor pairs. Two headphone outputs share one cue mix for collaboration, while the built-in talkback microphone keeps communication with performers simple. The Smart Display shows channel information, levels and Max gain reduction, with Auto-Gain and Clip Protection helping you set and maintain safe recording levels.
