Add Punch with Max Processing

Volt Max lets you punch up your vocals, guitars, bass, and other sources 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 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 Best-in-Class 32-Bit Converters

When you capture that perfect take, Volt’s 32-bit / 192 kHz converters preserve every detail, exactly they happen. And with loud, clear speaker and headphone outputs, you’ll get the perfect monitoring levels, from your first take to your final mix.

Capture Bigger Ideas with More I/O

With Volt Max, your audio interface never becomes a bottleneck. Use its dual-mic and Hi-Z instrument inputs to record multiple vocalists 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 4 Max’s 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 great take wrecked by digital distortion. Volt’s 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.
