▄ Regular Classroom Application
2.1. Medium-sized Regular Classroom Requirements
Medium-sized regular classrooms can have a network PA system installed to realize the combination of school ringing and local sound reinforcement.
Project Requirements
● Size: 600-800 ft2
● Number of students: 11-32
● A teacher holds a microphone and can connect to Bluetooth to play background music.
● The sound reinforcement system needs to provide clear and pure sound quality so that students and teachers can listen easily and improve the quality of teaching.
● Classroom sound reinforcement systems need to be easy to manage, easy to use, anti-interference, and convenient for school management and maintenance.
2.2. MAG6363G 2.4G Wireless Teaching System _with Network PA System
● Using 2.4G transmission mode, it can be used for local sound reinforcement and multimedia teaching of "one teacher holds one microphone"; it can also be connected to Bluetooth to play background music.
● The microphone has a built-in true reverberation function, which effectively improves the sound quality of speech, making it less dry or harsh, and the reverberation level is adjustable.
● The microphone supports PPT page turning: The PPT page turning module supports hot swapping and does not require driver software.
2.3. MAG6363M UHF Wireless Teaching System_with Network PA System
● Using UHF transmission mode, it can be used for local sound reinforcement and multimedia teaching; it can also be connected to Bluetooth to play background music.
● It uses a built-in electret pickup and designs an independent pickup cavity, which can effectively suppress howling and increase the pickup distance. The cavity has built-in acoustic sponge pads to minimize noise.
● The device has a pen-shaped body design, which is comfortable to hold and ergonomic. The buttons are partitioned and designed for easy operation. The appearance is fashionable, novel and beautiful, and the entire microphone (including the built-in microphone) weighs less than 40 grams, which is light and easy to hold.
● The microphone supports PPT page turning: The PPT page turning module supports hot swapping and does not require driver software.
2.4. MAG6420II UHF Wireless Teaching System_with Network PA System
● Wall Mount Network Wireless Microphone Control Panel (MAG6420II-C), uses RJ45 connection interface, supports 485 transmission protocol, and the maximum transmission distance is up to 300 meters.
● In irregular areas, it can be installed on the nearest wall to ensure signal stability. The receiving microphone stably transmits audio data within an open area 15 meters away from the "Control Panel (MAG6420II-C)".
● Using UHF transmission mode, it can be used for local sound reinforcement and multimedia teaching; it can also be connected to Bluetooth to play background music.
▄ Large Classroom Application
3.1. Large Classroom Requirements
The main demand for sound reinforcement in large classrooms is to ensure that the sound covers the entire classroom clearly and evenly, so that every student can hear the teacher's explanation clearly, and improve the quality and efficiency of teaching.
Project Requirements
● Size: 800-1000 ft2
● Number of students: 32+
● A teacher holds a microphone and can connect to Bluetooth to play background music.
● The sound reinforcement system needs to provide clear and pure sound quality so that students and teachers can listen easily and improve the quality of teaching.
● Classroom sound reinforcement systems need to be easy to manage, easy to use, anti-interference, and convenient for school management and maintenance.
3.2. Large Classroom--Teaching Audio System_Product Configuration
● The system host can support simultaneous use with two handheld microphones.
● Two pairing types: UHF and Infrared, rapid pairing, stabile and no distraction。
● The system host has two built-in frequency binding modules, and the sound is mixed and output when two handheld microphones are used at the same time.
● When setting different channels, the same microphone can be used in different classrooms without interfering with each other.
Design Highlights
● It adopts high-performance audio processing chip and ultra-low distortion sound processing circuit design.
● The advanced digital pilot technology and independent ID code design are adopted to prevent cross-frequency.
● Built-in feedback suppressor can effectively suppress howling and noise.
● The ultra-high frequency dynamic compression shunt technology automatically loads the high and low frequencies to show the best performance.
3.4. PPT Page Turning Function
Laser Pointer with Remote Control
● Supports PPT page turning function and one-click black screen/recovery function.
● Supports hot swapping, no need to install driver software.
● Plug and play (the handheld microphone needs to be paired with the receiving module first, and then the USB page turner is plugged in).
● Using a standard Class 3B laser module, the red laser spot is larger and brighter to clearly highlight the key points of the speech.
● Can be used with a projector or computer for presentation and explanation.
