SG series network amplifier

The SG series amplifier is a new SIP network amplifier from shollper Technology. It is a 19 inch 2U professional rack mounted network audio decoding device that performs functions such as broadcasting partition audio decoding and power amplification. Linux operating system architecture, standard SIP protocol, 10/100M Ethernet interface, supports LAN and WAN access. There are two output modes: constant voltage/constant resistance, multi zone broadcasting, and the volume of each input channel can be independently adjusted, supporting Bluetooth function. It can be widely used in various occasions such as campuses, parks and scenic spots, train stations, warehouses, hospitals, hotels, power plants, chemical plants, ports and docks, large factories, industrial and mining enterprises, iron and steel metallurgy, etc.

Product features:
