    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.

  • Page 6: System Configuration

    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...

  • Page 7: System Configuration Examples

    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.

  • Page 8: Example Use Cases

    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.
  • Page 9 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.

  • Page 10: System Design

    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).

  • Page 11: Recommended Installation Environment

    Recommended installation environment Speech reinforcement loudspeakers MAS-A100 units should be placed at least 2 m away from the loudspeakers. Installing 3 m or further away is recommended. This increases the limit of speech reinforcement. The speech reinforcement loudspeakers should be installed such that their output is not directed toward the MAS-A100 units in order to increase the maximum volume for speech reinforcement.

  • Page 14 Item Setting Description [Capture [Narrow], Controls the capture range. range] [Standard], The capture range is 2 to 3 m radius when set [Wide] to [Standard]. Setting to [Narrow] makes the capture range narrow, but the limit of the speech reinforcement level becomes higher. Setting to [Wide] makes the capture range wider, but the limit of the speech reinforcement level becomes lower.

  • Page 15: Rec Output

    The Rec output does not have microphone gain and muting settings. Control these using the recording system to which the Rec output is connected. Audio settings and signal processing functions The relationship between the audio settings and the MAS-A100 signal processing functions is shown in the following diagram.

  • Page 16: Network

    3.3 Network The MAS-A100 connects to the network switch over a single network cable, and has two IP addresses and two MAC addresses. One is for the output of Dante audio as a Dante device, while the other is for MAS-A100 setup and operation.
  • Page 17 Each unicast flow can contain up to four audio channels. The following diagram shows an example of one unicast flow, where the MAS-A100 sends the Main output and the Rec output to the Dante receiver of the DSP mixer.
  • Page 18 The maximum number of flows of each MAS-A100 is two. Therefore, it is necessary to use multicast flows instead of unicast flows if there is a need to send audio to three or more Dante devices. For details about Dante audio transmission using a multicast flow, refer to the Dante Controller user guide.

  • Page 19: Network Switch

    The power supply of the MAS-A100 is IEEE 802.3af compliant PoE class 0. The MAS-A100 power consumption is 9 W (typ) and 13 W (max). When a network switch connects to multiple MAS-A100 units or other PoE-compatible devices, be sure not to exceed the PoE power budget of the network switch.
