Studio Sound for the Full Band, at the Push of a Button
Home recordings and phone demos can sound thin and lifeless. Volt Max gives your recordings incredible tone right from the start. With three harmonic mic preamp modes — Warmth, Focus, and Shine — you can quickly add Tube, Solid State, and British Class-A tone to everything you record.

Add Punch with Max Processing
Volt Max lets you punch up your vocals, guitars, bass, and drums as you track, thanks to Max dynamics processing. With six push-button presets ranging from “Rap Vocals” to “Jangly Acoustic,” you’ll get big, radio-ready sounds based on our venerable 1176 and LA-2A studio compressors. Combined with its three preamp modes, it puts 18 inspiring sonic possibilities right at your fingertips.

Hear Every Detail with 32-Bit Converters
When you capture that perfect take, Volt Max’s best-in-class 32-bit / 192 kHz converters preserve every detail, exactly as it happened. And with loud, clear speaker and headphone outputs, you’ll get the perfect monitoring levels, from your first take to your final mix.

Capture Everything with Expanded I/O
The flagship Volt 4P Max gives you more of everything. It starts with four Tone Shaping Preamps to record multiple musicians and instruments at the same time. Tap into clean 48V phantom power for your fancy studio condenser mics. Connect your controllers and synths over MIDI. And with ADAT you can add eight more digital inputs, should the need arise.

See the Big Picture with Smart Display
Volt Max’s beautiful full-color Smart Display shows your inputs, levels, and settings in detail. So you spend less time setting up and more time creating.

Get the Perfect Levels with Auto-Gain
Nothing’s worse than a perfect take wrecked by digital distortion. Auto-Gain sets your recording levels in seconds, and Clip Protection catches unexpected peaks. So you can focus on the performance instead of the meters.

Start Making Music in Minutes
When you’re inspired, every second counts. Thankfully, Volt Max is ready, willing, and USB class-compliant on Mac, Windows, iPad, and iPhone.* No downloads or drivers. Works with any DAW. So you can be up and recording in minutes.

Shape Your Songs with UAD Plug-Ins and LUNA
Every Volt includes over 15 UAD plug-ins and instruments — the same software used to create and mix countless hit records for decades. Plus you get LUNA, our award-winning DAW with authentic “big studio” sound and smart tools designed to make recording easy.

Ideal for Larger Podcasts and Livestreams
Volt Max’s Loopback feature allows you to blend live sources with computer audio. So you can mix multi-guest podcasts and livestreams in realtime. Or just level up your video calls. There’s even a Talkback mic to communicate with talent. It’s the same way pro broadcasters work, built into every Volt.

*Requires an Apple Lightning to USB Camera Adapter (except iPhone / iPads with USB-C). Windows systems use the ASIO driver, available in the UA Connect app. Requirements for bus-power vary by model and device.
