You
can use the Volume buttons on the
remote control or projector to adjust the volume as you project a
presentation with audio. The volume buttons
control the projector’s internal speaker system or any external
speakers you connected to the projector.
You must adjust the volume separately for each
connected input source.
Note: When
streaming content using the streaming media player, you can use the
volume buttons on the remote control for Android TV or voice
commands to adjust the strength of the audio signal from the
streaming media player up to the current projector volume
(Epson 880X). To adjust the maximum volume
of the projector or external sound system, use the volume buttons
on the projector or projector remote control.
