Can the headset microphone and handheld microphone be used simultaneously by two people?
Yes, absolutely. The teacher can wear the headset microphone for lectures while passing the handheld microphone to students for interactive Q&A sessions. You can use either as a backup for everyday use.
Can I use it as a regular bluetooth speaker for parties or outdoor camping?
Yes. With dual high-power speakers, it delivers richer bass and clearer sound than typical amplifiers. Stream music via Bluetooth, sing along, or just enjoy as a portable speaker.
What are the advantages of UHF wireless connection?
UHF wireless offers two key advantages over Bluetooth/wired: 1.Zero latency – audio sync is instant; 2.Strong anti-interference – stable connection even in crowded electronic environments like schools or exhibition halls.
How can I prevent feedback/howling during use?
Any high-power amplifier may produce feedback if the microphone is placed too close to the speaker. We strongly recommend not pointing the microphone directly at the amplifier's speaker to avoid this issue.
