Project Background
As educational informatization and modernization continue to advance, campus auditoriums—serving as core venues for meetings, academic lectures, cultural performances, and multimedia instruction—require audio systems of exceptional professionalism and stability. As a district-level key school, Yuting Primary School in Xindu District, Chengdu is committed to creating a first-class teaching environment for its faculty and students. The school now plans a comprehensive upgrade of its auditorium's audio system, requiring high clarity, high stability, user-friendly operation, and the ability to meet diverse application needs.
HRA, leveraging its extensive expertise and numerous successful case studies in the field of educational audio-visual technology, has undertaken this key project. The objective is to build a comprehensive audio solution featuring advanced technology and outstanding performance.


Configuration Plan
Tailored to the specific requirements and acoustic characteristics of Yuting Elementary School's auditorium, the technical team at HRA conducted meticulous design and planning to deliver an integrated audio system centered on “superior sound quality, intelligent control, and stable reliability.” The core configuration is as follows:
Precision Sound Reinforcement System:
The system employs a combination of two TCEH12 and four TCEH10 full-range speakers. This configuration, meticulously calculated and calibrated, ensures uniform sound coverage throughout the auditorium. It delivers crystal-clear speech intelligibility and rich, powerful music reproduction, perfectly balancing the clarity required for presentations with the immersive impact needed for artistic performances.

Powerful Core:
To power the entire speaker system, three CQM-2.3S stereo amplifiers are included. These amplifiers deliver stable output and exceptional efficiency, providing pure, abundant power to the front speakers to ensure optimal system performance in any usage scenario.


Intelligent Control Hub:
The system's core control utilizes a 14-channel MX14 mixing console, featuring intuitive operation and extensive connectivity to flexibly handle multiple audio inputs and mixing adjustments, meeting the diverse sound reinforcement needs of campus events. Paired with an FBK-402 feedback suppressor, it automatically and precisely eliminates feedback, significantly enhancing the system's acoustic gain and speech intelligibility during meetings.

Reliable Power Management:
Configure one TPA908 power sequencing device to implement sequential power-on and power-off management for all equipment. This design not only simplifies daily operations but also effectively prevents current surges from damaging devices, ensuring the long-term stability and safety of system operation.
Project Feedback
Following project completion, the system underwent rigorous testing and multi-scenario trials, with its performance receiving unanimous high praise from university leadership, faculty, and students. The resounding success of this project once again demonstrates HRA's formidable capabilities in reliability, audio quality, and system integration!
