❑ “To Far-end” screen
In this screen you can make echo-cancel settings for the mics.
The mic signal after echo-cancellation is output to the remote location.
4 [Effect] box
Specifies the amount of echo cancellation. Higher numeric values allow more echoes to
be cancelled. However, the audio quality will decrease correspondingly, so you should
consider the balance between these factors as you make the adjustment.
5 [NR] button
These are on/off switches for the noise reduction function which removes steady-state
noise such as produced by a projector or air conditioner in the local location. We
recommend that you leave these on.

3 Meters
Mic In. meter ........ Indicates the level of the signal that is
input from your own mic (Near-end Mic).
Ref In. meter......... Indicates the level of the reference signal.
The most effective echo cancellation will
be obtained with a level at which the
yellow indicators light occasionally.
Echo Attn. meter.. Indicates the amount of echo cancellation
for each channel. Higher levels indicate
that the echo canceller is working.
ERL meter.............. Indicates the ERL (Echo Return Loss = the
level of the audio that is output from the
speaker and re-input to the mic). Echo
cancellation will work most effectively if
you adjust the position of the speaker and
mic so as to minimize this level.
