**Product Description**
The Classroom Audio System is a high-performance accessory designed
to elevate interactive whiteboard experiences in educational and
professional settings. Utilizing advanced 2.4GHz digital RF
technology, it ensures stable, interference-free transmission and
supports up to 1,000 non-overlapping frequencies for large-scale
deployments. The system includes a compact receiver box (no exposed
antennas) for enhanced signal stability and integrates a broadcast
priority interface for automatic signal switching. With a 50W
output, dual drivers (5.5" long-stroke woofer + tweeter), and
phase-reflex wooden enclosure, it delivers rich, balanced sound.
The accompanying multifunctional microphone features a laser
pointer, PPT navigation buttons, and dual modes
(handheld/lavalier), while offering 8-hour battery life and USB
charging.

7. Use 2.4G digital radio frequency technology to effectively avoid
transmission interference. Use 1000 sets of non-channeling
frequency at the same time to meet the needs of large-scale use in
the same place.
8. Automatically enter the pairing state when turned on. After successful pairing, there will be a prompt sound and automatically switch to the receiving state.
9. The intuitive LED LCD screen displays various technical parameters, digital volume adjustment, signal strength, and battery remaining information; it has a good windproof effect and clear sound quality.
10. The microphone has a laser pointer function and has up and down page turning buttons (the optional page turning module can realize wireless page turning, and can also black out the screen with one button when playing PPT files).
11. The microphone has a built-in microphone head, which can be used in both handheld and lavalier modes. It also has a 3.5mm external microphone interface, which can be used with a universal lavalier or head-mounted microphone or transmit other audio files. The microphone can be paired with any host. It will enter the energy-saving standby state within 60 seconds without signal or operation, and will automatically start when there is a signal or operation. There is no need to pair the frequency, the battery has low loss, and it can work continuously for more than 8 hours when fully charged.
12. The microphone uses a rechargeable lithium battery with a detachable interface, and is equipped with a travel (or USB charger) charger, which is more convenient to use. There is a prompt sound when the microphone is turned on, and the volume of the microphone can be adjusted.
