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.

*A loudspeaker system is required for speech reinforcement

Dedicated Channels for Speech Reinforcement and Recording

Our comprehensive solution employs audio volume stabilization and clear audio processing to produce sharp recordings. The MAS-A100 has two channel outputs. The dual-output channel enables speech reinforcement and recording simultaneously. The dedicated rec channel records with a wider capture range and optimal intelligibility—perfect for lecture capture.

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. 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 suppressing unwanted feedback (howling). 

A diagram showing how the Beamforming Microphone's feedback reducer works. We see how the teacher's voice is captured by the microphone and sent to the loudspeakers. The sound from the loudspeaker goes back to the microphone but is canceled out, eliminating the feedback

Noise reduction

Our Beamforming Microphone incorporates advanced noise-reduction technologies to minimize 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.

Automatic gain control

The MAS-A100 has a useful inbuilt volume normalization 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.

A diagram showing how Automatic Calibration works. Beamforming Microphone sends a test signal to the speakers which is picked up by the microphone. The microphone then adjusts its parameters based on this test signal

Automatic calibration

The Beamforming Microphone optimizes 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, minimizing time-consuming set-up and system maintenance.

  1. Generate test signal
  2. Capture test signal from loudspeakers
  3. Calculate and configure optimal parameters for speech reinforcement

Microphone Array System Manager (free download)

Our comprehensive solution includes free Microphone Array System Manager software (MASM-1). The software supports installation and configuration of initial settings, as well as monitoring, operations and firmware management. MASM-1 is a total management solution, enabling users to manage multiple microphones in multiple locations centrally and easily via the local network.

System Setup

Whether you’re integrating into a Dante audio system or an existing analog system, Beamforming Microphone provides simple integration with minimal fuss. You can also calculate how many microphones you need to deliver seamless lectures with our online configurator tool, which calculates the dimensions of your room to provide the optimum setup.

A diagram showing a typical Beamforming Microphone setup connected to a Dante audio system. The microphones are connected to a PoE switch which sends the signal to a Dante mixer. The mixer outputs two signals: the recording channel is sent to a lecturer capture recorder. The second signal is sent to an amplifier then to the loudspeakers on the main channel

The microphones are connected to a PoE switch and on to a Dante to analog converter which converts the signal to analog. The signal is then sent to the mixer which outputs two signals: the recording channel is sent to a lecturer capture recorder. The second signal is sent to an amplifier then to the loudspeakers on the main channel
