Overview
The Yamaha Music Laboratory Controller is a music education system that combines Yamaha know-how in music
education and electronics technology. This system is built to support communication between students and instructors
and to provide more uid guidance on individual and group performances. Instructors use the ML Touch application on
an iPad to operate the entire system, such as checking students’ performances, responding to questions and sending
performance data.
This system combines MRX7-D as the core of the audio network and MLA-200 (with a master unit for the instructor
and subordinate units for the students). Up to 24 subordinate units for students can be connected to one MRX7-D. At
maximum, a system can be built to connect 96 subordinate units with four MRX7-Ds.
This Setup Guide provides the necessary information for building and setting up the MLC-200 in a classroom. We
recommend that you read this information before and during setup.
