Universal Audio Volt 4 Max – Max Compression with Speaker Switching

Volt 4 Max builds a small control room around two Tone Shaping Preamps: Max Processing compression, Main/Alt speaker switching, talkback, two headphone outputs, extra line I/O, ADAT, MIDI and a USB hub, with a power supply in the box.

Key Features

• Tone Shaping Preamp: Three switchable characters per channel: Warmth (tube, 610-inspired), Focus (American solid state) and Shine (British Class-A)
• Max Processing: Six onboard compressor presets based on the 1176, LA-2A and VCA designs, tuned for vocals, guitar and bass
• Main and Alt Speaker Switching: Check mixes on a second pair of monitors at the push of a button
• Built-In Talkback Mic: Communicate with the performer between takes
• 12-in / 6-out with ADAT: Line inputs 3-4 plus 8 optical channels for outboard gear and expansion
• Smart Display: Gain-reduction metering, Auto-Gain and Clip Protection

Customer Benefits

Speaker switching, talkback and dual headphones are features you normally buy a separate monitor controller for. Here they sit next to preamps with tone and compression, so a desk setup can record, monitor and check mixes from one unit. The included supply keeps everything stable with a powered USB controller on the hub.
