MAS-A100 installation
When using speech reinforcement loudspeakers (Main output)
The audio capture range of an MAS-A100 for speech reinforcement is a hemisphere of
2 to 3 m radius (4 to 6 m diameter) with the MAS-A100 at the center. Consider the
height of the ceiling, the posture of the lecturer (sitting or standing), and the position
of the lecturer’s mouth, then design the installation so that the lecturer is within the
audio capture range.
It is recommended that the MAS-A100 be within 2 m distance from the lecturer.
