Description:
With remote control function, the UHF true diversity wireless microphone can be used to remotely control program playback. The hand-held microphone with remote control buttons and the receiver with data conversion function can be used together for broadcasting various outdoor activities.
Feature:
* 1U standard rack-mounted design, cabinet made of SPCC cold rolled plate material, aluminum panel, beautiful and practical appearance.
* Adopt UHF ultra-high frequency band dual true diversity reception, and PLL phase-locked loop multi-channel frequency synthesis technology.
* Provide a total of 600 channels, and true diversity reception, effectively avoiding frequency interruption and extending the receiving distance.
* With 8-level RF level display, 8-level audio level display, channel menu display, and mute display.
* Both balanced and unbalanced output ports are optional to meet different needs of device connections.
* The LCD supports the display of channel number / working frequency.The touch buttons are simple and user-friendly.
* The super anti-interference ability can effectively suppress external noise interference and co-channel interference.
* The infrared frequency matching function can synchronize the transmitter and receiver frequency quickly.
* The rich medium frequency makes the sound full of magnetism and power.
* The system platform can be configured with 20 groups of tasks, which can realize the music playback or real-time call at any time, on any number of terminals, and at any volume.
* Ultra-long wireless remote control distance; it can reach 800 meters with an antenna amplification kit in the open space where are out of obstacles.
* The main hand-held microphone has functional buttons and a LED display, and can realize many wireless remote control operations such as “start, pause/resume, stop, last, next, volume +, volume -”, and so on.
* Built-in audio acquisition and encoding module; the audio acquisition delay is less than 200ms; the system platform can preset the broadcast of the terminal or separate zones.
* Support DHCP, compatible with any network structure such as router, switch, bridge gateway, Modem, Internet, 2G, 3G, 4G, multicast, unicast, etc.
* Support the PA system remotely upgrading the terminal firmware, without the need to upgrade the terminal locally, reducing the work intensity of maintenance personnel.
