Inputs and outputs are made via 1/8" connectors including a dedicated headphone output and a sync output, which allows the Volca Mix to be used as a master sync generator to the connected volcas in the setup. A built-in stereo speaker is provided for portable performances. The Volca Mix can power up to three volca units and ships with a power supply, three audio cables, and three DC-to-DC volca power cables.

The Korg Volca Mix is a four-channel analog mixer designed for a live performance setup combining multiple volca units. The mixer offers two mono channels, a stereo channel, plus aux send and return functions for incorporating external effects. Each channel offers a hi-/lo-cut filter allowing you to contour the sounds of each device to create a polished mix. Additionally, the unit offers master effects including an analog stereo width expander and an analog dynamic range compressor with sidechain capabilities.
