Wireless Short Rod Representative Microphone Product Introduction

This microphone has a simple and atmospheric design. The microphone stem adopts a fine short pole method and is gold-plated MINI-6P with locking connectors, making it stable and reliable. It adopts the world's common 2.4G band and can be used without any frequency application when installing and using it. Its advanced 2.4G frequency hopping and digital transmission technology and complete communication protocols ensure the security of conference content to the greatest extent. The system can not only meet the needs of ordinary fixed-installation conference rooms, but also build mobile conference rooms, and provides a highly reliable conference solution on the premise of convenience and speed.
