Description
- Adopt unique digital U-band transmission technology, pi/4-DQPSK modulation mode, strong anti-interference ability, low bit error rate and stable transmission.
- A unique encryption method is used for audio transmission to ensure the security of meeting content.
- Adopt unique ID code pilot technology to prevent cross-frequency interference.
- Using high-reduction dynamic microphone core, professional sound cavity design, the sound quality presents natural and original sound.
- One-key frequency scanning to avoid interference; one-key infrared frequency matching, easy to operate.
- Support reverberation, treble/alto/bass adjustment.
- Designed with two balanced outputs and one unbalanced mixing output.
- The receiver panel is made of exquisite craftsmanship, neat and beautiful.
- The receiver adopts a 2.2-inch TFT-LCD screen, realizing more delicate display effect.
- The transmitter adopts an OLED screen to display the current information of the device clearly.
- The transmitter is ergonomically designed, round in shape to fit the hand, and comfortable to touch.
- The transmit power is adjustable, and can be adjusted as needed.
- With auto mute function, when the microphone is dropped or thrown, it will automatically mute in milliseconds to avoid impact sound. It will automatically mute after being left for 5 seconds, and automatically shut down after being left for 8 minutes.
- With one-key mute function, it is very practical.
- Using low-power design, the maximum continuous speech time is over 10 hours.
- The entire system includes a receiver + dual handheld wireless microphones.
