CM202U handheld wireless microphone
Special products:
1. True diversity receiver, dual channel independent selection system, can minimize the occurrence of cut-off frequency.
2. dual channel independent AFS frequency automatic search function, can quickly scan the work environment in the least worry frequency and lock.
3. The receiver and transmitter synchronize the codes with one key through IR infrared frequency matching technology.
4. professional performance level phase lock circuit, with noise lock noise control and digital pilot technology, when the transmitter offWhen closed, the pilot control will mute the AF signal to suppress the noise, and the corresponding receiver will be mute at the same time.Ensure the effective blocking of the dry signal.
5. Backlit LED display indicates RF and AF signal strength, battery status, diversity channel indicator (A/B), frequency, frequency group/channel, etc.
6. This product adopts the patented technology of "audio reference compression expansion", with excellent audio dynamic expansion response and automatic level control circuit.
7. The cm-202u true diversity wireless system is designed for touring and fixed installation purposes, providing the highest reliability, sound quality and transmission stability.
8. Optional head or collar.
