■ “AEC” component editor
This specifies AEC-related settings. The left side of the screen is Reference, and the right
side of the screen is for settings related to microphones connected to Mic In 1–16. If there
are more than five mics, a scroll bar will be displayed at the bottom.
Mic. 1–16
a
[ON] button
Switches between enabling or disabling AEC for each microphone.
b Level meters
These show the input/output levels and information related to acoustic echo.
• [IN] level meter
Shows the input level from the microphone.
• [ERL] level meter
Shows in real time the amount of sound (dB) collected by the near end microphone
from a remote location that was originally generated by a near end speaker (audio that
is an echo factor). A range from 0 dB to around –16 dB is a guideline for a good
installation environment.
If this meter shows a positive value, the following conditions may be applicable. Please
change so that ERL is a negative number. If it is lower than –16 dB, the microphone's
input level may be low.
