Specially design for external analog signal collection in IP network system, encoding analog signal to digital signal to transmit and broadcast to designated terminals.
		
	
		
	
Features:
		
	
* Full aluminum alloy shell and durable structure, small and delicate appearance.
* Adopt embedded computer and DSP signal processing technology, built-in high-speed industrial processing chip , to ensure the start-up time is less than 1 second.
* Built-in 1 channel audio encoding module of network hardware, support TCP/IP, UDP protocol, to realize network signal transmission with 16 bit CD sound quality.
* Built in 2 groups of RCA input terminals, with input volume adjustment, flexible matching with various devices with different sensitivity and support input audio voltage limit function.
* Support 5 zones to trigger on or off the collection function independently. The panel is equipped with 5 zone trigger buttons and indicator lights
* Support timing or temporary signal collection and broadcast task; the task priority levels can be set through the server.
* Support 3 collection and broadcasting modes:" ordinary collection and broadcast ", "medium collection and broadcast " and "Hi-fi collection and broadcast ". " ordinary collection and broadcast " can access the effect of ultra-low delay network audio acquisition, "medium collection and broadcast" can access the effect of low latency and ordinary sound quality of network audio acquisition, "Hi-fi collection and broadcast" can access the effect of ultra- low distortion of the network audio acquisition.
* Compatible with all network structures, such as router, switch, Bridge, Modem, Internet, 2G, 3G, 4G etc.
* It supports remote hardware upgrade of the terminal, no need to upgrade at the local site, to reduce maintenance burdens and make more simple operation.
* Support audio trigger collection task; AUX input can automatically trigger the collection task through the collection configuration of the server.
