Functional characteristics
1. Standard 19-inch frame design, black aluminum brushed panel, professional mechanical assembly process, the appearance of the machine is very high-grade.
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. Through the setting, the analog audio can be collected to any terminal of the IP network visual intercom broadcasting system, and the network audio can be decoded to the power amplifier for music playback;
6.3 AUX and MIC input interfaces, with independent volume and bass potentiometer control, support off-network local paging function.
7.★1 EMC input port, input emergency alarm voice signal is through.
8.2 audio signal auxiliary output interface, extensible external power amplifier, standard lotus socket interface, wiring connection is very convenient.
9. Microphone MIC1 has 48V phantom power supply to power the microphone.
10. 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.
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, 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.
