4 track Mixer Mx4v2s

In case the mixer and another piece of equipment are both supplied from the same external power source, never connect the battery ground to the chassis ground nor the signal ground - especially the audio input/output connectors. The audio signal would suffer interference, and the supply unit board could get damaged.

Disconnect the signal ground and the shield from the audio connector as shown above, or use an M3i Power adapter. This adapter allows to supply up to 4 external devices. Please note that old mixers (version 1 or 2) must be modified to support this adapter. Please contact us for details.
