Beamforming microphone
MAS-A100
A ceiling-mounted microphone, the MAS-A100 allows for totally hands-free presentations without the use of wired or wireless microphones. Amplify and record the speaker’s voice at the same time.
Overview
Achieves hands-free and natural “voice amplification”
The MAS-A100 is equipped with an intelligent noise feedback reducer and advanced beamforming technology developed by Sony for its professional microphones.
With these latest technologies, listeners can easily hear the speaker’s natural voice amplified, which has typically been challenging using ceiling-mounted microphones.

Simultaneously amplifies and records audio with a 2-channel output
Compatible with the digital audio network standard “Dante,” developed by Audinate, the MAS-A100 can simultaneously capture two audio channels one for amplifying the speaker and one for recording through a single network cable. It can connect to classroom speakers and clearly record lectures at the same time.
Easy installation, easy setup
The MAS-A100 is powered via PoE (Power over Ethernet). Because power is supplied through a network cable, battery management is no longer necessary, unlike wireless microphones. By laying just one network cable, you can cover all of the audio output, power supply, and settings management from a PC using the Dante protocol. With the calibration function, it’s easy to adjust the settings as needed at the time of installation.
Noise reduction
Eliminates ambient noise from projectors and air conditioners.
Auto gain control
Volume levels automatically adjust to best amplify the speaker’s voice wherever they are in the room.
