Mic-level (balanced) inputs supply optional 48 V phantom power
across both XLR ports. See
Enable or disable phantom power
Connecting devices that are not designed for
phantom power when phantom power is enabled on
the XLR ports can seriously damage those devices.
Always check the phantom power LED before
connecting devices to the XLR ports. A direct box can
be used to provide the correct mic-level signal to the
XLR port and offers some isolation protection in case
of accidental exposure to 48 V phantom power.
