*  Professional design of integrated and wall-mounted box structure, which is very strong and in line with the concept of modernization, elegant and graceful.

*  It adopts technology designs of both embedded computer and DSP audio processing. With High-speed industrial-grade chips, the starting time is less than 1 second.

*  Built in one way network hardware audio decoding module that supports TCP / IP, UDP, IGMP (multicast) protocol for network transmission 16 CD-quality stereo audio signal.

*  One line input, one line output, two way power output, it’s suitable for local broadcast.

*  Built-in 2×10W constant impedance amplifier which is connected with the outside speaker. The sound quality is very delicate and with strong power,speaker with network volume setting.

*  Compatible with arbitrary network structure, like routers, switches, Bridges, gateway Modem, Internet, 2G, 3G, 4G, multicast, unicast etc.

*  Digital products with easy expansion, without geographical restrictions, no additional room management equipment, the design concept of common network free line construction is adopted.

*  It supports remotely upgrade to hardware on the terminal, no need to go to upgrade at the local site, to reduce the working strength of maintenance worker.
