The expressive power and the strong dynamic tracking ability make the long and short distance pickup and playback freely; the built-in 6.3mm monitoring jack is suitable for the backstage monitoring function of large and small performances.

(2) External independent antenna output port, built-in frequency two-way encryption signal technology locking, adding frequency stabilization technology, completely solve the problem of signal dead angle cut in the effective range, reduce breakpoints and delayed signal breakpoints, and make reception more stable. long distance. Multiple sets can be used at the same time without serial frequency or interference.

(3) Two-channel receiver, with a 6.3mm unbalanced audio output port and two XLR balanced audio separate output ports for better detailed and independent control of each sound adjustment.

(4) Adopt 128-bit AES encryption technology, support WPA/WPA2 wireless security technology; support manual/automatic frequency coding function.

(5) The output audio volume can be adjusted; it has a high-strength anti-electromagnetic wave interference design for mobile phones, multi-level error correction and encryption, to prevent mobile phone electromagnetic interference and adjacent channel interference suppression, and super anti-howling suppression. Add an encryption lock function to prevent misoperation by non-professionals;

Transmitter parameters:

(1) PLL digital phase-locked loop multi-channel frequency synthesis technology is adopted, and digital transmission technology is adopted between the fully digital receiving host and the transmitting unit to ensure the privacy of signal transmission and avoid eavesdropping and malicious interference. The unit microphone can adjust different sound effects according to the voice characteristics of the speaker until the perfect effect is achieved; it adopts 128-bit AES encryption technology, supports WPA/WPA2 wireless security technology, has a high-strength anti-electromagnetic wave interference design of mobile phones, multi-level error correction and encryption , Eliminate mobile phone electromagnetic interference and adjacent channel interference suppression, and provide higher confidentiality of the conference system;

(2) Handheld microphone unit all-metal dual-tube dual-combination design; dynamic microphone core, equipped with howling suppression function circuit, brand-new audio circuit architecture, audio signal processing adopts international top high-performance audio processing chip, ultra-low distortion The sound processing circuit design has excellent performance in the details of the sound. The strong dynamic tracking ability makes the long and short distance pickup and playback freely; super anti-howling suppression; KTV projects, large and small performance projects, easy installation and debugging .
