1. Professional Rack-channel network audio decoding device, built-in digital power amplifier;
2. Installed in various regions of the weak occasionally broadcast management sub-control room, directly connected to the speaker circuit.

Features

1. Standard Rack Design (2U), black brushed aluminum faceplate, humane pumping hands, sophisticated technology, filling the high-grade temperament;
2. 3.5-inch TFT color screen display, screen-friendly, equipped with infrared remote control, clear display , simple operation ( fast forward / rewind / pause / [AB] repeat / Volume key operation, volume [+] [-] regulation );
3. Easy to operate, without manual settings; connect automatically to server once there is network.

4. Support wired network and WIFI wireless internet access modes;
5. Supporting two way accesses the network through cable or WiFi.

6. Supporting four ways for tracks : the server, local memory, U disk and line in.

7. Automatically complete the synchronization between timing program of terminal

and the server's , if server's programs change, there will be an automatic synchronization between the two parties.

8. Two kinds of working modes: online and offline, still can perform timing tasks

when there is network failure

9. Supporting incoming call of the uncast, multicast and all broadcast in LAN
10. The device uses an embedded linux technology and DSP audio processing technology design; using industrial-grade chips;
11. Built-in Network IP decoding module, support TCP / IP, UDP, IGMP (multicast) protocol, achieve network transmission of the 16 CD-quality stereo music signal;
12. Built-in 60W/150W/250W/350W/450W/550W/650W fixed-resistance (4-16Ω), constant-voltage (70V, 100V) power amplifier output, strong power, free matching;
13. 2 channels of lines (AUX) and one channel of microphone (MIC) input, achieve external audio input and implementation of local emergency broadcast input ,with separate volume control;
14. 1 channel of audio signal auxiliary output, facilitate expansion to external power amplifiers ;
15. Intelligent power management, when there is no music or call, the device will automatically cut off the main power supply and get into standby mode, the standby power consumption is less than 3W, meet national environment certification standards;
16. Local MIC signal priority auxiliary input AUX and network background music signal; auxiliary input AUX and network background music signal is at the same level, no priority; network emergency alarm signal has higher priority than local MIC, auxiliary input AUX and network background music signal;

17. Can connect to the Ethernet wherever there is a Ethernet port, support cross-segment and cross-routing.
