PERFORMANCE AND SPECIAL
With automatic mute and shock elimination circuit,to avoid the stroke and noise of the switch. The conference microphone has an LED digital tube display, can directly the current display frequency. Wireless transmission effective distance 30-50meter conference microphone adopts lithium battery circuit design, with overcharge and over discharge protection. Simple operation interface,very small adjustable components,can completely avoid malfunction caused by malfunction. Launch conference microphone has a low voltage detection and the batterycharacter flashes when the battery voltage drops to 2.2V. Extremely high sensitivity and excellent sound qualitymake your talking or singing easy. Multiple devices can be used at the same time,without interference andfrequency. With power and wireless indicator lights Support single frequency. Support to the unit in the preparationof the main technical.
