The Yamaha MLC100 Console is a key part of the Yamaha Music Laboratory, an integrated teaching system that includes a keyboard for the music instructor, up to sixteen student keyboards, headsets with microphones, and student call boxes. The Yamaha MLC100 is a flexible tool that will function with virtually any manufacturer's electronic keyboard. Organize Classroom Activities The Yamaha MLC100 lets teachers easily control classroom activities like ensemble playing, duets, one-on-one music instruction, students helping students, a student teacher assisting you with one, two, three or four groups—all of this can happen simultaneously using the MLC100 teaching console. And, you can instantly change the classroom configuration by pressing a single digital control. Efficiency Students of different playing abilities can attend the same music lesson and a student who misses a class can make-up a lesson with another group without scheduling valuable private time with the teacher. Convenience You can communicate with individual students, pairs or groups—privately, from your own keyboard, without disturbing other students or interrupting the entire class. Time Individual students of different levels and playing abilities plus those students requiring special assistance no longer hold up the progress of the entire class. Each student, pair, or group can be addressed independently, benefitting the entire class. Easy Installation Cables from the students keyboards cross the floor to the Yamaha MLC100 requiring only two plug in connections, giving easier, neater, safer installation.
