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.
