The terminal is installed in the storey computer room or sub-control computer room of each broadcas-
ting management area. It has a built-in high-fidelity amplifier, and is applicable to program broadcast
and local broadcast in halls, corridors, outdoors and other places.

3. FEATURES
1. Standard 19-inch rack design, black alumina wire-drawing panel, sturdy handle, professional
mechanical assembly process, and high-end appearance.
2. Industrial-grade 3.4-inch LCD display, which can clearly display most dot matrix patterns and
working status of the machine; equipped with an infrared remote control, any content VOD of the
server program library, flexible and simple operation of playback/pause.
3. The machine is designed with embedded computer technology and DSP audio processing technology.
4. Built-in 1 network hardware audio decoding module, support TCP/IP, UDP, realize the network
transmission of 16-bit CD-quality audio signals.
5. Built-in high-fidelity professional digital amplifier, with 60W/120W/240W/350W/500W/650W
constant voltage 100V power output.
6. One line (AUX) and one microphone (MIC) input interface, with independent volume and treble and
bass adjustment potentiometer control, and support local paging function when disconnected from
the network.
7. One EMC input interface, the input emergency alarm voice signal is straight through, with the
highest priority.
8. Two audio signal auxiliary output interfaces, which can be extended to external amplifiers, standard
RCA socket interface, wiring connection is very convenient.
9. One three-wire sound control override output interface, no need for override power supply.
10. Built-in intelligent power management, automatically cut off the amplifier when there is no music
or call, automatically turn on the amplifier when there is a signal, and support the function of
powering on the amplifier in advance by IP software programming.
11. Built-in 3 priority settings:
EMC is the highest priority.
The network alarm signal is prior to the MIC, AUX and network background music signals.
MIC takes precedence over AUX and network background music signals.
AUX and network background music are at the same level, without any priority.
12. Support the silent intensity preset reduction function, support the background music preset
function; support the status light display, including the level indicator, protection indicator, standby
indicator, etc.
13. Compatible with any network structure such as routers, switches, bridge gateways, Modem,
Internet, 2G, 3G, 4G, etc.
14. Digital products, easy to extend, not restricted by geographical location, no need to increase
computer room management equipment, adopt the design concept of shared network and no line
construction, which is easy to install.
15. Support the PA system to upgrade the terminal firmware remotely, no need to upgrade the terminal
locally, reducing the work intensity of maintenance personnel.
16. With USB playback function, access to U disk. Remotely play Random, Last, and Next music,
pause, stop and so on (or select the panel button operation).
17. One short-circuit input can be used to trigger preset voice prompts (or alarms), and can also be
used to control access control linkage to input short-circuit signals.
18. Come with 1 100V constant voltage power backup input interface, which can flexibly form a highly
reliable public ringing system with one master and multiple standbys, multiple masters and one
standby, and multiple masters and multiple standbys.
19. Built-in high-performance master/standby switching detection module, switch to standby power
input within 0.3 seconds when the network is disconnected and the machine fails, to meet the
requirements of a highly reliable public ringing system.
