Introduction Customer Support If you need assistance at any time during installation or when the MLC-200 system is in use, please contact Yamaha Customer Support at 714-522-9011 and when prompted to choose a support department, enter code 44. Overview The Yamaha Music Laboratory Controller is a music education system that combines Yamaha know-how in music education and electronics technology.
Items necessary only for setup Windows computer Use to specify settings during setup. A computer with an RJ-45 connector and running Windows 10, Windows 8.1 or Windows 7 is required. ML Config Tool This software automatically configures the audio network connection between the MRX7-Ds and MLA-200s. Install this software on a Windows computer.
1. Trial setup Before installing the devices in the classroom, perform a trial setup of the entire system to check the setup and operation of each device. Since it will be difficult to remove and attach the DIP switch cover and change the DIP switch settings after the MLA-200 is installed onto an instrument, we recommend checking the setup and operation of each device prior to installation on the instrument. 2.
3. Setting up MLA-200s Each MLA-200 in an audio network is differentiated by the unique ID that is specified. Specify this ID with the DIP switch. 3-1. With nothing connected, open the DIP switch cover on the rear panel. One side of the cover remains attached. Disengage the side that does not remain attached, and then slowly open the cover. Dip switch cover 3-2. Set the DIP switch. The switches of the DIP switch are set to ON when it is down and OFF when it is up.

5. Setting up the Dante 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 MLC200 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 Dante Audio Network — continued Connection diagram showing 15 students. NOTE • Before making connections, be sure to complete the procedure in “3. Setting up MLA-200s” (Page 6). The changes to the DIP switch settings are applied when the Ethernet cable is connected and the MLA-200 is turned on. Before changing the settings, unplug the Ethernet cable from the MLA-200.
5. Setting up the Dante Audio Network — continued Connection diagram showing 24 students.
5. Setting up Dante Audio Network — continued 5-2. Start the ML Config Tool installed onto the Windows computer. A window appears. Follow on screen steps to set up the Lab System. 5-3. In “The number of MLA-200” box, type the number of MLA-200s connected Include the MLA-200 for the instructor with the number of devices for Area #1. Area #1 can be set between 2 (for 1 instructor + 1 student) and 25 (for 1 instructor + 24 students); Area #2 to #4 can be set between 1 (for 1 student) and 24 (for 24 students).
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. Scan here to download from the app store. 6-2. Tap the ML Touch icon to start the application. The initial setup window appears.
7. Connecting optional audio devices Connect audio devices, such as the instructor’s microphone or Audio/Video Device used for teaching, to the MRX7-D set to ID=1. STPLONG-MLC Audio Cables PoE powered Ethernet switch Audio/Video 2 Audio/Video 1 MRX7-D ID=2 MRX7-D ID=1 NOTE Use the Euroblock connectors on the MRX7-D to make the microphone input and speaker output connections. Power amplifier 7-1. Turn off all devices to be connected. Indoor speaker L Indoor speaker R 7-2.
8. Operation check Refer to page 10 of Quick Setup Guide for Testing and Troubleshooting.
9. Installing onto an instrument (optional) After performing the operation check, unplug all cables connected to the MLA-200s, and then install the MLA-200 onto the instrument.
9. Installing onto an instrument (optional) — continued 9-2. While holding the MLA-200 in the desired position, drill four holes (for attaching the mounting bracket) into the instrument’s stand (leg). Drill holes with a depth of 15 mm and diameter of 2.5 mm at the center of the screw holes, positioned at least 15 mm inside the edge of the stand (leg). Be careful not to drill the holes too deep. In addition, be sure to drill all four holes.
9. Installing onto an instrument (optional) — continued 9-5. Install and tighten the other screws. 9-6. Tighten the center screw last. 9-7. Make sure that all screws are properly tightened. This completes the installation onto the instrument. Installation examples Mounted with screws at the top This is the most common installation method. Use this method when the stand (leg) of the instrument is wide.
9. Installing onto an instrument — continued Mounted with screws on the side 15 mm or more Use this installation method when the instrument stand is toward the back of the keyboard. As described in “Installation precautions (attaching to the instrument with included screws)” (Page 18), maintain a distance of 15 mm or more between the center screw and the edge of the stand, and install by using all four screws.
9. Installing onto an instrument — continued When placed on a flat surface When placed on a flat surface of the instrument, be sure to attach the included rubber feet to prevent slipping. The installation positions should be about 15 mm inside each edge as shown below. Be sure to attach all four. Caution Position the MLA-200 so that no one will trip and nothing will catch on the cables. If the MLA-200 falls, it may be damaged or cause injuries.
10. Final operation check After installing the MLA-200s onto instruments and setting up the devices, reconnect the cables, and then perform the final operation check. The procedure for this operation check is the same as that described in “8. Operation check” (Page 17), but this time the operation is checked after setting up the system in the classroom. 10-1. Check that the MLA-200 for the instructor can be operated from ML Touch.
11. Troubleshooting Symptom MLA-200 does not turn on Cause Remedy The Ethernet cable is disconnected Reconnect Ethernet cable PoE power is not supplied by the network switch Make sure that a PoE powered Ethernet switch is used The PoE power supplied by the network switch is insufficient Check the power supply specifications of the Ethernet switch The [MASTER VOL.] knob or [MY VOL.
