Phantom power (+48 V DC) is provided. This can be switched on or off by the +48 V phantom switch .

Care should be taken NOT to plug mics into the console (or stagebox) while the phantom power is on. Also, mute the monitor/PA speakers when turning phantom power on or off. Allow the system to adjust for a couple of seconds after engaging phantom power before setting input gains.

If possible, connect the unit to other devices in a balanced configuration to allow for maximum interference immunity.
