Description
Reduces steady-state noise in a classroom or
a meeting room (e.g., fan noise of air
conditioners and projectors). The effect is
weakest when set to [Low], and strongest
when set to [High].
Notes
The noise may not be reduced

sufficiently in some MAS-A100
installation environments.
The unit is not effective for the reduction

of random noise (e.g., noise of typing on
a keyboard or writing on a blackboard).
Controls the gain of frequency equalizer
bands at 60 Hz, 250 Hz, 1 kHz, 4 kHz, and 12
kHz.
Description
Controls the level of feedback reduction.
Setting to [High] achieves greater feedback
reduction, but decreases the audio quality.
Adjusts the noise gate. Noise gate
attenuates the audio when the input level is
small. The effect is weakest when set to
[Low], and strongest when set to [High].
Note that the beginning of speech may be
lost due to the slight delay in detecting sound
input.
Usually, set this to [Off]. If the level of noise
reduction achieved using [Noise reduction] is
insufficient, set this to [Low], [Middle], or
[High].
