In the era of blended learning, ensuring consistent audio quality across a range of classrooms of varying sizes and purposes is a major challenge for facilities managers. How can costs be optimized while maintaining stability and quality of instruction?

The success story at the Yanqi Lake campus of the University of Science and Technology of China (UCAS) provides the perfect solution for today's smart school model.

Challenge: Heterogeneity in Educational Infrastructure

With 33 classrooms of varying sizes, structures, and usage needs (from large conference rooms to small group classrooms), UCAS faced significant technical challenges:

Audio Interference: Noise from equipment and surrounding environment hindered recording.
Latency: The outdated system failed to meet the demands of real-time remote learning.
Complexity: The excessive use of devices such as handheld microphones and traditional lapel microphones made instructors feel cumbersome and technical maintenance difficult.
Breakthrough Solution from the AISpeech Ecosystem: The Combination of MC10 and MC08

To thoroughly address these issues, UCAS adopted an integrated solution from AISpeech, flexibly combining two specialized device lines: MC10 and MC08.

1. AISpeech MC10 – The "Heart" of Large Classrooms

For large lecture halls, the system uses a combination of MC10 devices with a pickup radius of up to 8m.

AI Noise Reduction: Integrated AI technology effectively eliminates background noise.
Low Latency: With a latency of only 25ms, audio transmission is almost instantaneous, ensuring a vivid remote teaching experience as if you were in the room.

2. AISpeech MC08 – Flexibility for Any Space

In group classrooms or flexible meeting spaces, the MC08 (4.5m pickup radius) is the optimal choice to completely eliminate cumbersome handheld microphones.

Advanced Noise Filtering Technology: Automatically filters out over 300 different types of noise, allowing instructors to move freely while maintaining clear and authentic voices.

3. Customizable "Reception Zone" and "Silent Zone"

The advantage of this system is its intelligent setup capability. The technical team can customize the sound pickup zones to focus on the lectern and set up silent zones to eliminate unwanted noise, creating a precise sound environment according to user requirements.

Why is UCAS's solution becoming the new standard?

Successful implementation in 33 UCAS classrooms has demonstrated outstanding effectiveness:

Perfect compatibility: The system operates smoothly with many other supporting devices such as existing lapel microphones or handheld microphones.
"All-in-one" solution: Fully meets needs from: on-site sound reinforcement, online teaching, to high-quality lecture recording.
Budget optimization: Significantly reduces the cost of investing in individual equipment, installation costs, and periodic maintenance. Simplifying operational processes significantly reduces the workload for the technical team.
