Leicozic 1000M Long Distance Wireless Microphone Professional Microfono Diversity Receiver Hand Mic Headset / Lavalier Mike

Features:

1. Using self-developed unique high-sensitivity true diversity signal selection circuit, the signal of each microphone is received by a double circuit. It can effectively reduce the occurrence of frequency interruption in the use range and improve the use distance.

2. High-power transmitter design. The optimal ratio between power consumption and continuous use time is achieved.

3. It is specially designed for school playgrounds/large and medium gymnasiums/etc. that need long-distance speech. The optimal receiving distance is up to 1000 meters. No need to install any amplifier.
