1. Introduction
This document describes the design of a system that uses MAS-A100 Beamforming
Microphones and an MASM-1 Microphone Array System Manager, and the required
information for setup and operation. Refer to the MAS-A100 Operating Instructions
and the MASM-1 Help Guide.
The MAS-A100 Beamforming Microphone is a beamforming type, ceiling-mounted
microphone with a speech reinforcement and clear audio recording system for
hands-free, hassle-free operation covering locations over a wide area.
Lecturers and presenters can use both hands freely when giving lectures and
presentations, without troublesome preparation and equipment operation.
The unit also supports Dante audio transmission and PoE (Power Over Ethernet)
power supply. It can be connected to various Dante-compatible audio systems using a
single network cable.
The MASM-1 Microphone Array System Manager is Windows application software for
configuring and operating an array of MAS-A100 Beamforming Microphones
collectively by remote control via a network.

2. MAS-A100 Overview
This section provides an overview of the MAS-A100 Beamforming Microphone.
Audio capture function
The MAS-A100 integrates eight directional microphone capsules and the signal
processing functions, as shown in the following diagram. It enables audio capture
features for speech reinforcement and for recording, corresponding to the Main output
and the Rec output, respectively.
The Main output exploits a unique feedback reduction technique, and can be
connected to a speech reinforcement system and played back by loudspeakers in a
room. The Rec output is optimized for recording of clearer audio over a wider area.
Audio output function
The MAS-A100 is compatible with the Dante system and achieves long-distance
transmission of low-latency, high-quality, digital audio. Main and Rec (2) outputs are
multiplexed and output using a single Cat 5e LAN cable. Also, the power supply for the
MAS-A100 is supplied by the same cable using PoE.
Setup and management function
The MAS-A100 has two IP addresses. One IP address is for output of the captured
audio using the Dante system. The other IP address is for MAS-A100 setup using the
web app or external API.
MASM-1 and Dante Controller software by Audinate (referred to as “Dante
Controller”) on a PC connected to the same segment (same layer 2 network) are used
to initialize the MAS-A100 units and route Dante audio, respectively.

3. System Configuration Example
This section shows an example system configuration using the MAS-A100.
3.1. Recording a lecture in a small room (no speech
reinforcement)
The following system configuration shows the unit installed for recording a lecture in
a small room with a width of 7 m, a depth of 9 m, and a ceiling height of about 3 m.
One MAS-A100 unit mounted on the ceiling in the center of the room above the
lecturer is used to capture audio.
The capture range of the Rec output is a hemisphere of 7 m radius (14 m diameter), and
one unit can cover the recording of the lecturer and audience. The Rec output of the
MAS-A100 connects to the recording system via a Dante/Analog converter (Audinate).

3.2. Reinforcing/capturing a lecture in a medium-sized
room
The following system configuration shows units installed for reinforcing speech and
recording a lecture in a medium-sized room with a width of 10 m, a depth of 20 m, and
a ceiling height of about 3 m. Three MAS-A100 units mounted on the ceiling at
intervals of 2.7 m above the lecturer are used to reinforce speech and capture audio.

The Main output and the Rec output of these MAS-A100 units are mixed by a Dante
DSP mixer and connected to a speech reinforcement system and a recording system,
respectively.
The speech reinforcement quality and volume can be increased by not installing
loudspeakers near the front of the room.
