2. The application of embedded computer and DSP audio processing technology, high-speed industrial single-chip microcomputer chip, startup time is less than 1s.
3.★ Support associated major monitoring brand camera function, when the shout/intercom can be displayed through the IP network visual console bound camera video screen, truly visual broadcast.
4. Built-in 1 network hardware audio decoding module, support TCP/IP, UDP, IGMP (multicast protocol), to achieve network transmission of 16-bit CD audio signals.
5.1 Route (AUX) and 1 channel microphone (MIC) input interface, with independent volume and high and low bass adjustment potentiometer control, support off network local paging function.
6. 1 EMC input interface, input emergency alarm voice signal is through, with the highest priority.
7.2 audio signal auxiliary output interface, extensible external power amplifier, standard lotus socket interface, wiring connection is very convenient.
8.★2 three-wire audio control force-cutting output interface, no need for force-cutting power supply. At the same time, it is compatible with four-wire fire protection strong cutting, which requires external 24V strong cutting power supply.
9. 1 circuit short circuit input, 1 circuit short circuit output, support flexible custom functions, can achieve short circuit collection, alarm trigger, and achieve fire, monitoring and other third-party equipment and platform linkage application.
10. Built-in intelligent power management, automatically cut off the power amplifier when there is no music or call, automatically turn on the power amplifier when there is a signal, support IP software programming pre-open power amplifier function.
11.★ Built-in priority function: network music, MIC1 microphone, EMC alarm, three signals can be freely set any signal priority through the dip switch, easy to use;
12. Support mute intensity preset reduction function, support background accompaniment preset function; Support status indicator display, including level indicator, protection indicator, standby indicator, etc. The standby power of the whole machine is less than 10W, which meets the national environmental protection and energy saving certification standards.
13. Compatible with any network structure such as router, switch, bridge gateway, Modem, Internet, 2G, 3G, 4G, 5G, multicast, unicast, etc.
14. Digital products, convenient expansion, not limited by geographical location, no need to add computer room management equipment, the use of common network line free construction design concept, easy installation.
15. Optional functions: 4G full Netcom Internet access function, meet the 4G full Netcom wireless Internet broadcasting function.
