    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.
  • Page 10 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.

    The audio capture range of an MAS-A100 for speech reinforcement is a hemisphere of 2 to 3 m radius (4 to 6 m diameter) with the MAS-A100 at the center. Consider the height of the ceiling, the posture of the lecturer (sitting or standing), and the position of the lecturer’s mouth, then design the installation so that the lecturer is within the...
  • Page 17 120 cm Multiple unit installation To capture a wider area, install multiple MAS-A100 units separated at fixed intervals, and mix the output of the units at the same volume. In such an installation, the MAS-A100 units capture audio with less noise, so sound quality abnormalities due to interference between the MAS-A100 units are less likely to occur, making the audio capture clearer.

    Speech reinforcement level adjustment By exploiting the beamforming function and feedback reduction technique, the Main output of an MAS-A100 unit can be connected to a speech reinforcement system and played back to achieve hands-free speech reinforcement. When using the Main output of the MAS-A100, a test signal generated by the...

  • Page 19: Installation Environment For Speech Reinforcement

    Install speech reinforcement loudspeakers such that their directivity field does not point towards the MAS-A100, and with a separation of 2 m or more from the MAS-A100. Installing 3 m or further away is recommended. When installing MAS-A100 units on the ceiling above a classroom dais, it is recommended that the loudspeakers be placed close to the audience.

  • Page 21: Calculator For Speech Reinforcement

    You can configure the capture range on the MAS-A100 setup screen. Noise can be reduced by reducing the audio capture range of MAS-A100 units that are close to noise sources to match the movement of the lecturer.

  • Page 22: Installation Environment For Audio Capture

    Installation environment for audio capture The audio capture performance of the MAS-A100 is affected by the use of the speech reinforcement function, installation location, shape of the room in which it is installed, materials of the room, and ambient noise environment. This section describes the recommended installation environment for the MAS-A100 for audio capture.

  • Page 23: Network Design

    MAS-A100 network function overview The MAS-A100 connects to a network using a single LAN cable (Cat 5e or higher), but internally it has two network interfaces. Each network interface has a separate MAC address.

  • Page 24: Ip Address Design

    Operation on an IPv4 network is recommended. Two IP addresses (an IP address for setup and an IP address for Dante) must be assigned to each MAS-A100 unit. There are three methods supported for obtaining an IP address. To prevent conflicts, it is recommended that the same method be used for both network interfaces.

  • Page 25: Setup Network Communications Protocols And Ports

    IPv6, but in most cases there is no need to use it. To prevent inadvertent access, it is recommended to disable IPv6 routing on the router of the network to which the MAS-A100 is connected. Dante does not support communication across routers or IPv6.

  • Page 26: Poe

    14336 to 14600 Unicast destination The MAS-A100 must be powered by a PoE class 0 equivalent power supply function that complies with IEEE 802.3af. The MAS-A100 power consumption is 9 W (typ) and 13 W (max). When a PoE hub connects to multiple MAS-A100 units or other PoE-compatible devices, be sure not to exceed the PoE power budget of the PoE hub.

    This section describes the design for connecting MAS-A100 units to the system. MAS-A100 audio output overview The MAS-A100 functions as a Dante transmitter device with two channels of audio outputs (Main output and Rec output) on a Dante network. Design how to route the separate outputs to the speech reinforcement system and recording system, respectively.
  • Page 31 Rec output to the Dante receiver of the recording system. 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.

  • Page 35 Since the MAS-A100 has a Dante audio output, D/A conversion is required to connect to an existing analog speech reinforcement audio system. In addition, in environments where a Dante-compatible DSP is installed, the Dante audio and the audio system for speech reinforcement can be connected directly using digital audio signals.

Speech reinforcement is achieved by connecting the analog audio signal to the line input of an existing audio system.
  • Page 37 Analog connection with existing audio system for speech reinforcement using 2 MAS-A100 units The Dante audio output of the MAS-A100 is used as the Main analog audio signal by using an Audinate ADP-DAO-AU-0x2. The signals are mixed 1:1 using a fixed-gain mixer, unity gain mixer, a microphone combiner, or splitter cable.

    Configure the routing of the audio signals between the Dante devices (register the logical connection to the Dante devices). This section describes routing the output of the MAS-A100 to a Dante receiver device (digital mixer or Dante/Analog converter). Routing is performed using Dante Controller installed on a PC connected to the same segment (same layer 2 network) as the MAS-A100 units in a room where the MAS-A100 units are installed.

    Main output. Calibration is required when the MAS-A100 units are installed, when the loudspeaker or MAS-A100 position is changed, or the settings for the audio system is changed.

  • Page 63: Calibration Preparation

    During the calibration of an MAS-A100, other MAS-A100 units for speech reinforcement in the same audio system should be muted. MASM-1 automatically switches calibration and muting of MAS-A100 units one at a time when calibrating a selection of multiple MAS-A100 units. All microphones other than the MAS-A100 units should be muted (low volume or switched off) during calibration.

    Press the [Flash] icon to start the LED lamp of the MAS-A100 flashing to confirm its location, if necessary. Press the [Test signal] icon of an MAS-A100 used for speech reinforcement to output a test signal. The test signal is a voice saying “Test, one, two, three” at an output level (–16 dBFS) equivalent to speaking at a volume of 63 dB SPL (A) from a distance of 1 m in an environment where no feedback occurs.
  • Page 65 The MAS-A100 captures the noise signal played from the loudspeakers, and this is used to simulate the positional relationship with loudspeakers and the acoustic characteristics of the room to optimize the audio processing for feedback reduction.

    Enables/disables the feedback reduction function and controls the level of feedback reduction. When feedback occurs due to close proximity of the MAS-A100 and loudspeakers or due to calibration not performed normally, the frequency of the feedback is suppressed by lowering the gain to stop the feedback.

    Installation in locations that require this feature to be used at all times is not recommended. Take measures to reduce the noise, such as moving the MAS-A100 away from the noise source and lowering the noise level in the room.

  • Page 73: Microphone Gain

    For high-quality speech reinforcement, set to [Standard] or [Narrow] and ask the speaker to speak with a loud voice or have the speaker stand close to the MAS-A100. When using [Wide], maintain a large distance between the MAS-A100 and the loudspeakers, and reduce the sound pressure entering the MAS-A100 from the loudspeakers as much as possible.

  • Page 112: Appendix B. External Control

    To enable the API, set [API control] to [Enable] on the [System] page of the [Settings] tab of MASM-1. When the API is enabled, a network port of the MAS-A100 is opened, and the unit is accessible from external sources via that port, which is a potential security risk. Make sure that the API is enabled only when connected to a secure network.
