IP Based PA System


Installed in low voltage or sub-control room in the radio management area , built-in high-fidelity power amplifier, suitable for the hall, corridor, external and other areas of the program broadcast and local radio.



  • Standard 19 inch rack design, black aluminum panel, solid handle, professional mechanical assembly process, the appearance is very high-end.
  • Industrial grade 3.4-inch LCD display, it can clearly show the majority of dot pattern and machine work status; equipped with infrared remote control, on-demand all contents in server program library, can control the playback / pause, flexible and simple operation.
  • Using embedded computer and DSP audio processing technology, high-speed industrial-grade SCM system chip, start time is less than 1s.
  • Built-in 1 network hardware audio decoding module, support TCP / IP, UDP, IGMP (multicast protocol), to achieve network transmission 16-bit CD audio quality audio signal.
  • Built-in high-fidelity professional analog amplifier, with 60W / 120W / 240W / 350W / 500W constant resistance (4-16 Ω) and constant pressure (70V, 100V) power output.
  • 1 line (AUX) and 1 microphone (MIC) input interface, with independent volume and treble/bass adjustment potentiometer control, support broken
  • 1 channel EMC input interface, enter the emergency alarm voice signal is direct connection(Without switching), with the highest priority.
  • 2-channel audio signal auxiliary output interface, can extend to external connect power amplifier, the standard lotus seat interface, wiring connection is very convenient.
  • 1 channel three-wire system control override output interface, no need external override power. At the same time compatible with four-wire fire override, need to external 24V override power.
  • Built-in intelligent power management, when there is no music or call, it will automatically cut off the power amplifier, when there is signal, it will automatically turn on the power amplifier, support IP software programming pre-open power
  • Built-in 3 priority settings
  • EMC is the highest priority.
  • The network alarm signal is higher priority than MIC, AUX and network background music signals.
  • AUX and network background music for the same level, without any priority.
  • Support silence intensity preset decrease function, support background accompaniment preset function; support status light display, including level indicator, protection indicator, standby light and so on. Machine standby power is less than 3W, to meet the national environmental protection and energy saving certification standards.
  • Compatible with routers, switches, bridge gateway, Modem, Internet, 2G, 3G, 4G, multicast, unicast and any other network structure.
  • Digitalized products, easy expansion, not limited by geographical location, no need to increase the engine room management equipment, adopt a total network of free road construction design, easy to install.
