❑ “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.

1 AEC [ON] button

Switches the echo canceller function on/off.

2 REFERENCE [A][B][C][D] buttons

These buttons select whether the signal specified by the From

Far-end selection will be used as the AEC reference signal

(REFERENCE).

If multiple signals are selected, they will be mixed.

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.
