CM201U handheld wireless microphone




Special products:

1. Double channel single receiving system. The unique and highly sensitive diversity selection circuit developed by ourselves 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. Phase lock circuit of professional performance level, with noise lock and digital pilot technology, when the transmitter is off, 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. The SQ receiving distance is adjustable from -65~ -100dbm, and it has the function of operation lock key to prevent misoperation.

7. Rongsheng electronic technology independently developed audio system technology, with high dynamic response, wide frequency response, eliminate the noise brought by high frequency, and achieve excellent sound quality.

8. Independently developed the core technology "VCO and rf circuit" to make the available bandwidth larger and the signal reception more stable.

9. Optional headwear or jacket is supported.
