CONFIGURATION
This unit automatically tracks the talker's voice. The
talker's voice can be picked up with very narrow
directivity so that background noise can be significantly
reduced. The voice of only one talker can be picked up at a
time.
While the "Mic Area" screen is being displayed, press a
numeric key to specify the area in which the tracking
function is disabled. Each time you press the numeric key,
the tracking function is enabled or disabled in the
direction as shown below.
y
• Pressing the numeric key (5) enables the tracking
function in the all areas.
• You can select multiple areas at the same time.
Select [Menu] - [Settings] - [Mic Area].
Configure the acoustic echo cancellation setting
depending on your operating environment. Normally, you
do not need to change it from "Low" (default).
• Low (default): Select this setting when this unit is used
in an ordinary conference room, open space, or office.
The communication quality is most stable in this
setting.
• Mid: Select this setting if echo is produced at the other
party when this unit is used in "Low". This setting is
suited for use in a room with high reverberations.
• High: Select this setting if echo is still produced at the
other party when this unit is used in "Mid".
"Mid" and "High" can improve the echo processing capability but
lowers the communication quality. These settings should be
selected only when echo is produced at the other party.
Select [Menu] - [Settings] - [AEC Effect].
