Karaoke Wireless Microphone Receiver System UHF Channel 2 Handheld Dynamic Mic

Description

Features:
■ UHF high frequency (650-690MHz) frequency modulation, frequency modulation in the transmitter
■ One to two FM, 2*30 channels
■ A/B channel switch button is set on the handheld microphone, and the microphone can be used as A/B microphone
■ Fixed display on the receiver display
■ Brushed metal panel, the receiver and handheld transmitter adopt a durable metal shell (the handheld material is all metal aluminum tube)
■ Dual antenna reception, set 1 6.5 output and 2 Karon balanced outputs at the same time, suitable for connecting various external devices
■ UHF wireless dual-channel reception, automatic frequency binding, automatic wireless lD code reception and use, complete the wireless synchronization of the transmitter, dedicated GPIO indicating the energy of the received audio signal, dedicated GPIO indicating the synchronization status of the transceiver, no infrared window pairing, realizing one-time pairing , N times of frequency modulation, saving the steps of each frequency, simplifying the complexity
■ Dedicated data channel: 7Kbps, internal CRC check, audio and data use 32-bit encrypted word transmission, encrypted transmission, effective anti-serial frequency, not easy to conflict with other machines in the same field
■ 8-band audio equalization, optimizing the picked up sound, making the restored human voice more beautiful
■ The microphones have built-in high-quality filter sponges, which can effectively filter environmental noise
■ It has a wide range of applications, such as home theaters, KTV rooms, conference speeches, high-end clubs, school teaching, hall performances, meeting rooms of enterprises and institutions, etc.
