In response to the need to provide a high-quality, seamless hybrid learning experience, the institution deployed Xilica Solaro DSPs with built-in HearClear AEC (acoustic echo cancellation) technology in 20 of the school’s large-scale lecture halls.
Challenge
One of the primary challenges HEC Montréal faced was delivering high-quality audio in these facilities. This mandated the need for in-room digital signal processing (DSP) systems that delivered maximum flexibility and a sufficient number of inputs and outputs to support the devices of both faculty and students. Acoustic echo cancellation was also a high priority to ensure smooth communications between on-premise class participants and those attending remotely via Microsoft Teams. Network interoperability and compact form factor were also required to facilitate quick and low-profile deployment, and IT-friendly operation, monitoring, and maintenance.
Solution
Each lecture hall was equipped with a quarter-rack-width Xilica Solaro QR1 processor fitted underneath the instructor’s lectern. The Solaro QR1’s built-in HearClear AEC software eliminates in-room echo and echo generated by remote attendees, both of which were overwhelmingly prevalent before Xilica. Built-in Dante technology for networked audio facilitated the seamless integration of these new systems with the school’s existing technologies.
The impressive modularity of Solaro DSPs provided greater value from an operational standpoint. Each Solaro QR1 is equipped with XC-SUB USB cards, providing volume and mute status sync for Microsoft Teams. The Solaro QR1 effortlessly processes audio captured from Sennheiser TeamConnect Ceiling 2 beamforming microphone arrays located above the speaker.
Impact
HEC Montréal’s new Xilica Solaro systems provide both faculty and students with smooth, high-quality audio performance that results in a better learning experience for both in-room and remote class participants. The integrated HearClear AEC technology professionally removes the disruption of unwanted echo and noise, while built-in Dante audio networking streamlines operations, monitoring, and management. The modularity of Xilica’s systems also provide the additional advantage of scalability as hybrid learning continues to evolve.
