Product Description
Digital Wireless Conference Microphone System With Headset MicrophoneFEATURES
Microphone Features
1. Built-in 3-group stacker frequency, one-key recall. The same frequency band can be easily used for three sets of stackers at the same time.
2 With IR infrared automatic frequency pairing function, one-key automatic frequency pairing lock.
3. The four-channel volume is independently adjustable. Provides 4+1 audio output. The four-channel audio volume output is independently controllable.
4. Provide a variety of transmitters to choose from. The conference/handheld/lavalier in the transmitter can be mixed and used. Don't worry about each other.
5. The backlit LED display indicates the working status of RF and AF signal strength, frequency, frequency group/channel, etc.
6. Using the same working frequency of 4 channels, the transmitters can be interchanged at any time, which greatly enhances the flexibility of operation.
7. Using the latest UHF band wireless audio transmitter chip module IC. It has superior RF performance and audio performance, providing customers with professional-grade sound quality experience. Combined with noise lock squelch control and digital pilot technology, when the transmitter is turned off, the pilot control mutes the AF signal to suppress noise, and simultaneously mutes the corresponding channel of the receiver. It ensures the effective blocking of disturbing signals.
Receiving Host Features
1. The new concept of anti-electromagnetic interference circuit design eliminates the electromagnetic interference of mobile phones and other electrified products;
2. High-definition COG display, the Chinese menu is clear at a glance, and the operation is simple;
3. Adopt two-channel/four-channel/eight-channel receiving design, which can connect two/four/eight wireless conference microphones;
4. Contains 40 groups/20 groups/2*20 groups of preset frequency modules, PLL phase-locked loop loop design, pure automatic selection of receiving methods;
5. One-click to modify the two-channel/four-channel frequency group, two-channel/four-channel simultaneous modification of the frequency group, and also supports manual modification of the frequency of each communication, which is convenient for debugging and installation;
6. Light ring shuttle knob design, with LCD liquid crystal display, to display volume, module, frequency and AF/RF signal strength and setting operations;
7. Using electronic volume control, the volume gain of each channel can be adjusted from 0dB to 20d through the front shuttle knob;
8. Infrared data automatic synchronization function (SYNC): 2/4/2*4 independent infrared frequency pairing buttons, one-key automatic frequency pairing, eliminating all complicated operations;
9. Adopt UHF530-670MHz frequency band carrier;
10. Standard 2/4/8 BNC antennas, and can be equipped with external extended anti-jamming antennas, which can bypass the shielding of wireless signals by metal cabinets, and the effective working distance is 60 meters (visual distance);
11. Cooperate with the antenna distribution system to achieve full wireless signal coverage at the venue;
12. Standard cabinet design with metal shell 1U/2U, easy to install.
