University of Arizona Selects Yamaha ADECIA Ceiling Microphone and Line Array for Superb Sound in the Classroom

Yamaha UC enhances the classroom audio experience for in-person and virtual students at the University of Arizona (UA). The higher education institution’s Systems and Industrial Engineering and Mining and Geological Engineering departments selected and installed the award-winning ADECIA ceiling microphone and line array speaker system for lecture recording and video conferencing.

“With ADECIA, everyone on the other end can easily hear attendees in the room clearly, even as they walk around the room,” said Zachary Chapman, senior systems administrator at UA. “The microphone picks them up clearly, without picking up background noise from the room’s air conditioning unit. In addition, there are far fewer troubleshooting calls to the IT department. It’s a success, in my opinion.

ADECIA is an innovative family of communication products that provides a complete and customizable audio solution, delivering the most comfortable and easy remote conferencing experience for any meeting or learning space. The easy-to-install solution is comprised of four Yamaha products: a choice of microphones (RM-CG Ceiling Array, RM-TT Table or RM-W Wireless), the RM-CR processor, Yamaha’s longstanding PoE switches , and VXL series line array speakers. The complete solution immediately detects all system components and optimizes their configuration for the room environment, taking into account speaker and microphone placement, reverberation and echo behavior. Setting up a room is done via the system configurator in four simple steps. With USB, Bluetooth, Dante and analog connections, this flexible system can adapt to a variety of meeting spaces.

UA’s two classrooms required only one RM-CG ceiling microphone each, demonstrating its powerful room coverage. The Systems Engineering classroom can accommodate 30-40 people, while the Department of Mines classroom can accommodate up to 50 people. The team installed the ceiling microphone towards the front of each classroom, close to where the teacher normally stands and speaks. Thanks to ADECIA, despite the large size of the room, students asking questions from anywhere in the room are now successfully picked up by the ceiling microphone.

“Great sound is an invaluable part of learning,” said Holger Stoltze, Ph.D., senior technical sales and marketing manager, Yamaha Unified Communications. “ADECIA simplifies edtech decisions, purchasing and installation while delivering incredible audio coverage in a customizable, virtually plug-and-play kit. The deployment of ADECIA at UA demonstrates that no element has been overlooked in the pursuit of exceptional learning experiences.
