[Calibrate] Tab

Calibration screen (1/2)

  1. Checkbox

    Place a check mark beside each MAS-A100 that you want to calibrate.

  2. [Name]

    Displays the status lamp, name, and IP address of each MAS-A100.

    The color of the status lamp indicates the status of the MAS-A100.

    Calibration cannot be performed when the MAS-A100 is offline (status lamp is gray).

  3. [Description]

    Displays the description of each MAS-A100.

  4. [Flash]

    Press the icon to start the LED of the MAS-A100 flashing.

  5. [Output level]

    Displays the output level using a green audio level bar. This cannot be changed.

  6. [Gain limit]

    Displays the gain limit status.

  7. [Mic gain]

    Displays the default value of the microphone gain.

    This cannot be changed using this screen.

  8. [Test signal]

    Press the icon to output an audio test signal (0 dB level). Press again to stop the test signal.

  9. [Status]

    Displays error messages for each MAS-A100 if a problem occurs.

  10. [Calibrate] button

    Press the button to start calibration. A noise signal is output from each MAS-A100 for about 5 seconds.

    For multiple MAS-A100 units, each MAS-A100 outputs the noise signal in sequence.

Result screen (2/2)

Note

  • Items without a description are the same as on the calibration screen.

  1. [Gain limit]

    Displays the gain limit status.

    When one lamp is displayed, the microphone gain has reached the limit for suppressing feedback and maintaining audio quality.

    When two lamps are displayed, the microphone gain has exceeded the limit and that audio quality has deteriorated.

    To avoid deterioration in audio quality, set the microphone gain in the range so that the gain limit lamps are not lit or only one lamp is lit.

  2. [Mic gain]

    Displays the default value of the microphone gain.

    This is set to –12 dB immediately after calibration.

    Press the +/– buttons, or press the value and enter a new value directly, to change the setting.

  3. [Test signal]

    This cannot be operated using this screen.

  4. [Status]

    Displays a 5-level rating of the calibration. The higher the rating value, the higher the limit for speech reinforcement of the audio.

    If the rating is [Fair (2)] or [Poor (1)], review the installation environment of the MAS-A100 and the audio system settings, and then perform calibration again.

  5. [Close] button

    Applies the microphone gain settings, and exits calibration.
