X220U wireless microphone

Carrier frequency band: UHF adjustable (650-653MHz, 660-663MHz) Digital audio transmission technology Unique digital ID code pilot technology, ID code 32bit, completely solve the same frequency crosstalk phenomenon. Ultra low audio delay. Audio sampling mode: 48KHz. Frequency range: 50Hz - 18KHz. Receive automatic scanning Open environment theory transmission distance: 20-30 meters Microphone type Picking up way heart pointing Frequency range 650-653MHz, 660-663MHz RF bandwidth 60MHz Frequency points 8 Transmitting power 10mW Frequency response 50Hz - 18KHz Dynamic range 96dB Harmonic radiation <-50dBc Distortion <0.1% Power supply mode One 1200mA lithium battery (3.7V) Frequency range 650-653MHz, 660-663MHz RF bandwidth 60MHz 8 frequency points Signal to noise ratio 96dB Receive sensitivity -95dBm If there are multiple sets of products in the same environment, crosstalk may occur (same frequency with the same ID code) Caused by the following steps, the pairing operation can be completely solved. 1. Adjust the transmission and reception to the shutdown state at the same time; 2. Transmitter: Press the power switch and the frequency hopping button simultaneously for about 4 seconds, the display will flash quickly. status; 3. Receiver: Turn on the receiver power, the RF indicator flashes 4 times; 4. Transmitter: Short press the frequency hopping button to exit pairing. Power switch 2. Frequency hopping switch Power switch 2. RF LED Frequency response 50Hz - 18KHz Distortion 0.05% Dynamic range 96dB Receive delay 2.5ms Power supply mode 12000mA lithium battery (3.7V)
