Universal Audio Volt 4P Max - 12in / 6out Audio Interface
The Volt 4P Max is a flagship desktop USB audio interface featuring four tone-shaping preamps, a smart display with a clear visual interface, speaker switching, and Max dynamic processing. Together, these features provide drummers, bands, and producers with the connectivity they need to record extensive sessions with the full sound of a professional studio.
Developed by the same Universal Audio team that created the legendary Apollo interfaces, the Volt Max delivers studio-quality mic preamp sounds and classic compression on every channel at the touch of a button. Plus, when it’s time to finalize your recording, you’ll have access to a perfectly matched suite of award-winning UAD plug-ins and the LUNA Digital Audio Workstation.
