20
Echo Canceller Mode
Determine whether or not to use Echo canceller.
21
Signal Limiter
Set the Singnal Limiter Mode.
22
Echo Canceller NLP Mode
Non-linear processing mode.Enable this option to
decrease the low level echo. When NLP is enabled,
the voice with low level is replacecd with NLP noise.
As a result, a low echo of the level is usually
removed compared with the conversation level.
24
Echo Canceller NLP Noise Setting
Becomes invalid item if 84-12-22 is set to Disabled.
Set the noise level adjusting method added with
NLP.
When "0" is set, the level is self-adjusted - when "1"
is set, Program 84-19-23 is used.
26
TX (Transmit) Gain
Define the setting to amplify and to attenuate the
