Designed for meeting, lecture and presentation environments, the ceiling-mount microphone is for both speech reinforcement and recording with what they claim is a unique combination of beamforming technology and “intelligent feedback reducer” function. The microphone has a dual-channel output for simultaneous recordings in large areas to capture both the speaker and students/participants voices. Together with the support for Dante and PoE to enable easy installation, the MAS-A100 will significantly improve the audio experience in education and corporate organizations.
Here’s a video that explains the technology:
The MAS-A100 achieves hands-free speech reinforcement without requiring hand-held or body-worn microphones and subsequent batteries or device management. This is enabled by a unique combination of beamforming technology and an original feature called “intelligent feedback reducer” which can extract speech sound while suppressing unwanted feedback with Sony high-performance digital signal processing and unique algorithms. After capturing voice, the microphone’s Automatic Gain Control function automatically adjusts the output volume to be consistent regardless of the presenter’s location.
The beamforming microphone has dual-channel output thus achieves speech reinforcement and recording simultaneously by using the dedicated output channels. It covers a wide range and allows to record not only the speaker’s voice but also the students and participants. The microphone also has auto-noise reduction capabilities to minimize background sound from air conditioners, projectors etc. all of which make it ideal for lecture capture and meeting recording.
Sony says the microphone has the support of Dante, PoE (Power over Ethernet) and has a unique Automatic Calibration function automatically optimizes the parameters of the audio processing for speech reinforcement by generating and capturing the test signal during the installation process. Sony also includes Microphone Array System Manager software (MASM-1) can help centralize the settings and management of multiple microphones in various rooms connected via IP.
