Music Laboratory System Installation Guide 3
Introduction
Overview of the Music Laboratory System
The Yamaha Music Laboratory System is a music education system that combines Yamaha’s
abundant know-how in music education and electronics technology. This system is built to support
communication between students and instructors and to provide more fluid guidance on individual and
group performances. Instructors can use the 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 Music Laboratory
System in a classroom. We recommend that you read this information before and during setup.
