CAUTION
When tuning the switch on ( ), be sure that only condenser
mics are connected to the XLR input. Devices other than
condenser mics may be damaged if connected to the phantom
power supply. Note, however, that the switch may be left on
when connecting to balanced dynamic microphones.
To avoid damage to speakers, be sure to turn off amplifiers (or
powered speakers) before turning this switch on or off. We also
recommend that you turn all output controls to their minimum
settings before operating the switch to avoid the risk of loud
noises that could cause hearing loss or device damage.
