You can
connect a microphone to the projector's
Mic port to provide audio support during
presentations.
Note: If you
connect a condenser microphone with plug-in power support, turn on
the Plug-in Power setting in the
Extended menu. If you want to output audio from the external
speakers when the projector is turned off, you need to select
Communication On for the
Standby Mode setting and
Always On for the A/V Output setting in the projector's Extended
menu.
