Introducing Sony’s beamforming ceiling microphone with advanced speech reinforcement technology – enabling truly hands-free and contactless lectures and presentations.
Contactless, hands-free ceiling beamforming microphone with speech reinforcement capability
The MAS-A100 is a state-of-the-art speech reinforcement* and recording solution. Attaching and positioning lavalier microphones is time-consuming, and handheld microphones restrict movement. However, the Beamforming Microphone is simply affixed to the ceiling, then ready to use – leaving the orator location-free, hassle-free and hands-free to focus on presenting. And what’s more, operation is totally contactless, reducing risk of infection for users. *Loud speaker system is required for speech reinforcement
Dedicated channels for speech reinforcement and recording
Our comprehensive solution employs audio volume stabilisation and clear audio processing to produce sharp recordings. The MAS-A100 has two channel outputs. The main channel provides speech reinforcement in a classroom environment, while the dedicated rec channel records with a wider capture range and optimal intelligibility – perfect for lecture capture and remote learning*. The dual output channel enables true hybrid learning by providing speech reinforcement in the classroom, and recording for remote learning simultaneously, to create a true hybrid learning solution. *Lecture capture system required **Pre-testing recommended for remote learning applications.
Simple installation and management
Supporting Dante and PoE, MAS-A100 links with third-party systems via a single cable connection. Auto-calibration streamlines system configuration, and settings can easily be adjusted via the network using free MASM-1 management software. Permanent ceiling installation ensures hands-free and contactless operation. And with simple settings, central management and no need to monitor battery use, MAS-A100 is a convenient classroom audio solution.
Beamforming and Intelligent Feedback Reducer
The integration of beamforming technology and our market-leading Intelligent Feedback Reducer produces clear audio with hands-free speech reinforcement, leaving the presenter hands-free. Sony’s high-performance digital signal processing and unique algorithms extract speech sound while supressing unwanted feedback (howling).
Noise reduction
Our Ceiling Microphone incorporates advanced noise reduction technologies to minimise ambient noise. Stationary background noise arising from projectors and air conditioning are automatically detected and reduced to achieve clear sound resulting in better intelligibility and, ultimately, better understanding for listeners. In addition to this, the Ambient Noise Filter* feature automatically detects and filters out intermittent and distracting sounds, such as the typing of a keyboard, click of a mouse or the turning of pages. (Version 1.1) *The Ambient Noise Filter feature is scheduled to be available in March 2021.
Automatic gain control
The MAS-A100 has a useful inbuilt volume normalisation feature to maintain stable volume regardless of the distance between the presenter and the microphone, leaving the presenter free to move around the space without the audio quality deteriorating. Automatic gain control adjusts the strength of the signal received to ensure clear and consistent sound for easy listening.
Automatic calibration
The Beamforming Microphone optimises the parameters of audio processing for speech reinforcement automatically. The microphone generates a test signal, which is captured by the loud speakers. The system then calculates and configures the parameters for speech reinforcement. This calibration is required only on initial installation, minimising time-consuming set-up and system maintenance.
