5. Setting up the audio network Communications between the instructor and students as well as audio of the performance is sent and received through the audio network. In the Music Laboratory System, Dante has been adopted as the structure of the audio network. Although software called Dante Controller is normally used to set up a Dante audio network, its high degree of flexibility requires knowledge about audio networks.
5. Setting up the audio network 5-1. Connect all MLA-200s to Ethernet switches. The [STATUS] indicator flashes while the device is starting up. The indicator lights up when the device is finished starting up. Check that the [STATUS] indicator of all MLA-200s are lit.
5. Setting up the audio network 5-2. Before starting the ML Config Tool, in the Control Panel of the Windows computer, disable all network adapters (including Wi-Fi) except the one for the built-in RJ45 connector connection. Make sure that only the wired network adapter connected to the Music Laboratory System is enabled. 5-3. Start the ML Config Tool installed onto the Windows computer. A window appears. 5-4. In “The number of MRX7-D” box, type the number of MRX7-Ds to be used. 5-5.
5. Setting up the audio network 5-6. Click the “Confirm” button. The software automatically checks that the MRX7-Ds and MLA-200s are correctly set up. If they are correctly set up, “Succeed” appears in the “Output” box on the right side of the window. If this does not appear, return to the previous steps and check each of the settings. 5-7. Check that “Succeed” appears, and then click the “Apply” button. This completes the setup of the audio network.
6. Setting up ML Touch ML Touch is an iPad application used by instructors to operate the entire system. It can be downloaded from the App Store. This describes the setup operations that must be performed before the application can be used. For details on using ML Touch, refer to the ML Touch User’s Guide. 6-1. Download ML Touch from the App Store. 6-2. Tap the ML Touch icon to start the application. The initial setup window appears. Then, if there are no problems, the Home window appears.
