Suzuki's new Piano Lab Teaching System puts you in charge by allowing easy monitoring and communication with every student in your keyboard class. Our verbal switching network allows for 2 way communication and lets you monitor the progress of up to 10 students at a time, and you can add systems to make classes up to 30 students! Performance can be monitored on an individual basis or split your class into two groups based on lessons learned. Talk to any student individually or in groups and they can talk back! Pre-recorded lesson plans or informational tapes can be played and explained through the system. Our new Piano Lab Teaching System is the most affordable product available today.
