Recommended installation environment
Speech reinforcement loudspeakers
MAS-A100 units should be placed at least 2 m away from the loudspeakers. Installing 3 m
or further away is recommended. This increases the limit of speech reinforcement.
The speech reinforcement loudspeakers should be installed such that their output is
not directed toward the MAS-A100 units in order to increase the maximum volume for
speech reinforcement.
When installing MAS-A100 units on the ceiling above a classroom dais, it is
recommended that the loudspeakers be placed close to the audience.
Acoustic characteristics
It is recommended to use a room with low reverberation and low reflection acoustic
characteristics.
Speech reinforcement may not be applicable in a tiny room (e.g., smaller than 5 m ×
5 m), or in rooms with reflective interiors, such as vinyl tile floors or stone walls.
Noise
MAS-A100 units cannot be used in environments where there is noise louder than the
voice of the speaker requiring reinforcement.
The MAS-A100 has a limited ability to reduce steady-state noise. It is recommended
that units be installed as far as possible from equipment, such as air conditioners and
projectors.
The MAS-A100 has no ability to reduce random noise. If installed near audience
seating, the background noise of the audience may be reinforced or recorded. When
not installing on a ceiling, make sure that the sound of footsteps are not captured.
Calculator for speech reinforcement
Calculator for speech reinforcement calculates 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.
