Operations during Communication through IP Network
■ Configuring the speaker mode
You can select the audio output mode of the speakers
during a call.
y
You can display the "Speaker Mode" menu by holding down
in the initial display or calling display.
• Multi (Default): When this unit is connected to
multiple locations, the audio from other units is
automatically divided according to their locations. The
audio from each location is divided and output from the
left, center, and right side of the speaker if a conference
call involves 3 locations. If a conference call involves 2
locations, the audio is output from the left or right side
of the speaker. If a conference call involves a single
location, the system creates a virtual sound source for
the talker according to the position of the talker in the
remote location.
• Monaural: The audio from other units is not divided
according to their locations.
■ 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.
Notes
• "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
the "Setup guide" (a separate manual).
