This product is a digital wireless microphone system with a new solution architecture. The system adopts unique digital U-band transmission technology and pi/4-DQPSK modulation method. It has low bit error rate and stable transmission. Compared with most U-segment analog modulation in the industry, the product has the advantages of strong anti-interference ability, ID code pilot technology to prevent same-channel crosstalk, and frequency scanning to avoid interference. It can be widely used in conferences, training, teaching, KTV, broadcasting, weddings, large parties and other places.
* Adopting unique digital U-segment transmission technology and pi/4-DQPSK modulation method, it has strong anti-interference ability, low bit error rate and stable transmission.
* The system includes an economical receiving host + a lavalier bodypack transmitter + a headset bodypack transmitter.
* The receiver panel is made with exquisite craftsmanship and is elegant and beautiful.
* Support audio encryption function. After turning it on, the microphone and receiver use unique ID code pilot encryption technology to achieve the effect of no cross-frequency of the equipment..
* Support automatic frequency scanning function, which can quickly find a clear frequency for the transmitter and is easy to operate.
* Supports easy pairing of transmitter and receiver via infrared scanning and synchronization..
* The receiver has two balanced outputs and one unbalanced mixing output to meet the different needs of users.
* The receiver uses a 3.6-inch VA-LCD display. The user can view the device’s RF signal strength, audio signal strength, transmitter on status, transmitter battery status, current frequency value, volume, etc. through the display, and can easily obtain the current status of the device information.
* The transmitter uses a 0.96-inch OLED screen. Users can check the device's transmit power intensity, audio encryption status, battery power, frequency value, and mute mark through the display screen.
* Volume adjustment buttons are available on the transmitter for user adjustment.
* The transmitter has a one-button mute button, which is very practical.
* Adopting low power consumption design, the maximum continuous speaking time is more than 10 hours.
* The transmitting power can be adjusted in 7 levels, and the transmitting power can be adjusted as needed.
