Configuring the room size
You can configure this setting depending on the room size
and operating environment. However, you do not need to
change it from “Large” normally.
•
Large (Default)
: Select this setting for using this unit
in an ordinary conference room, open space, or office.
The communication quality is most stable in this
setting.
•
Medium
: Select this setting when this unit is used in a
room with large reverberations. This setting reduces
the echo heard at the other party locations using the
“Large” setting.
•
Small
: Select this setting when echo is still heard at the
other party locations using the “Medium” setting.
• “Room Size” is a function for reducing the echo heard at the
other party locations. “Room Size” cannot reduce the echo that
is heard from this unit installed at the local location.
• “Medium” and “Small” can improve the echo processing
capability but lowers the communication quality. These settings
should be selected only when echo is heard at the other party
locations.
■
External input/output
Select whether or not external audio equipment is
connected to this system. For details, refer to “Configuring
the external input/output setting” (page 19 and page 30) in
