The other is an ambient noise filter function that reduces sporadically occurring noise.
This function makes keyboard type sounds and paper rustling sounds less likely to be
captured.
Both functions cannot be used in environments where there is noise louder than the
voice of the speaker requiring reinforcement. There are limits on the ability of the
functions to reduce noise. It is recommended that units be installed as far as possible
from sources of noise.
When not installing on a ceiling, use cushioning material or sound absorbing material
so that the sound of footsteps and desk noises are not captured.
You can configure the capture range on the MAS-A100 setup screen. Noise can be
reduced by reducing the audio capture range of MAS-A100 units that are close to
noise sources to match the movement of the lecturer.
Calculator for speech reinforcement
The “Calculator for speech reinforcement” web site can be used to calculate the
coverage of the MAS-A100 units and the intervals between multiple units so that the
mouth of a lecturer walking around the lecturer’s dais is always within the radius of the
coverage.
