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.

6
2. System Configuration
The MAS-A100 connects to a network switch over a single network cable that carries
Power over Ethernet (PoE), two-channel outputs of Dante audio, and remote-control
information for setup and operation.
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. An MASM-1 on a
PC placed not only in the same segment but also beyond a layer 3 switch (for example,
on a PC placed in a control room) can perform MAS-A100 configuration and operation
after initial setup.
This document describes the details of setup and operation using the MASM-1,
however, the web UI interface integrated with the MAS-A100 can also be used.
2.1 Audio capture
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.

Output Use Capture range
Main output Speech
reinforcement
2 to 3 m radius hemisphere.
(2 m is recommended for higher quality of speech
reinforcement.)
Rec output Recording 7 m radius hemisphere.
2.2 System configuration examples
Connecting to a Dante-compatible digital mixer
The following diagram shows an example system configuration where the Main output
and the Rec output of two MAS-A100 units are converted and mixed to analog audio
by a digital mixer, and connected to a speech reinforcement system and a recording
system, respectively.
Connecting to analog mixers
The following diagram below shows an example system configuration where the Main
output and the Rec output of an MAS-A100 unit are converted to analog audio by
Dante/Analog converters, mixed by analog audio mixers, and connected to a speech
reinforcement system and a recording system, respectively.

2.3 Example use cases
Small size classroom
Only one MAS-A100 mounted in the center on the ceiling of a small size classroom
covers the recording of the whole classroom.
The Rec output of the MAS-A100 passes through the recording system of the
classroom via a Dante/Analog converter. 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 whole small size classroom.
Middle size classroom
Two MAS-A100 units mounted on the ceiling above the lecturer’s dais of a classroom
are used for both speech reinforcement and recording of the lecturer. Another

9
MAS-A100 unit is mounted on the ceiling above the audience seating and is used for
recording the audience.
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 capture range of the Main output of the MAS-A100 units is a hemisphere of 2 to 3
m radius (4 to 6 m diameter), and two MAS-A100 cover the speech reinforcement of
the lecturer around the lecturer’s dais of a middle size classroom.
The capture range of the Rec output of the MAS-A100 is a hemisphere of 7 m radius
(14 m diameter), and three MAS-A100 units together cover the recording of the whole
middle size classroom.

3. System Design
3.1 Installation
Installation of multiple microphones
The capture range of the Main output of an MAS-A100 unit is a hemisphere of 2 to 3
m radius (4 to 6 m diameter). The capture range of the Rec output is a hemisphere of
7 m radius (14 m diameter).
To capture a wider area, install multiple MAS-A100 units separated at fixed intervals,
and mix the output of the units. Since audio can be captured with very low noise, an
auto-mixer is not required for mixing the output of the units.
Make sure to mix the audio channels of the Main output and audio channels of Rec
output separately. Note that a mix of the Main output and the Rec output cannot be
used.
It is recommended that an auto-mixer not be used for mixing the Main output, as its
automatic gain adjustment function may interfere with calibration (see “4.2
Calibration”).
Installation environment and level of speech reinforcement
By exploiting a unique feedback reduction technique, the Main output of an MAS-A100
unit can be connected to a speech reinforcement system and played back by
loudspeakers in a room. However, there is a limit with the feedback reduction
technique, and the level (audio volume) of the speech reinforcement is limited
depending on the installation environment.
Calibration is necessary before using the Main output of the MAS-A100 to optimize the
settings for the installation environment. For details about the calibration process, see
“4.2 Calibration”. Note that the Rec output is not dependent on the installation
environment.
