Volt 4 Gen 2

Tone-Shaping Preamps
Choose from Warmth, Focus, and Shine modes to add tube, solid-state, or British Class-A character while recording.

Flexible Analog Inputs
Mic, line, and instrument connections accommodate vocals, instruments, stereo sources, and external studio equipment.

Digital Expansion
The optical input supports additional channels through ADAT or a stereo digital source through S/PDIF.

Automatic Level Control
Auto-Gain sets recording levels quickly, while Clip Protection helps prevent unexpected peaks from distorting a take.

Full-Color Display
Clear visual feedback provides quick access to input levels, channel settings, and other recording information.

MIDI Connectivity
MIDI input and output connect compatible controllers, keyboards, synthesizers, and drum machines.

Independent Phantom Power
Each microphone channel provides individually switchable phantom power for compatible condenser microphones.

Loopback Audio
Computer audio and live sources can be combined for podcasts, livestreams, video calls, and other content.

USB Bus Power
Power from a compatible computer or mobile device supports recording without an external power supply.

USB Hub
An onboard USB port connects compatible peripherals and can power external MIDI controllers.

Production Software
Included recording software, plug-ins, instruments, effects, and amplifier tools provide a complete starting point for music production.
