Functional characteristics
1.★ 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.
2. 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.
3. Built-in 2x50W dual-channel digital power amplifier, one way to the main speaker, one way to the sub-speaker; The sound quality is very fine, the power is strong; Has network volume Settings.
4.★1 route (AUX) and 1 microphone (MIC) input interface, with independent volume, reverberation and high and low bass adjustment potentiometer control, support off network local paging function. At the same time, it supports the function of silence intensity presetting reduction and background accompaniment presetting.
5.★1 EMC input port, input emergency alarm voice signal is through.
6.1 audio signal auxiliary output interface, extensible external power amplifier, standard phoenix interface, wiring connection is very convenient.
7. Built-in priority function: network music, MIC1 microphone, EMC alarm, 2.4G teaching, four signals can be freely set any signal priority through the dip switch, easy to use;
8. 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.
9. Built-in fixed voltage backup module, to achieve access to 100V fixed voltage broadcast line as a backup, in line with the education committee college entrance examination must have a backup system requirements; When the network is abnormal, it automatically switches from "IP network visual intercom Broadcast" to "analog constant voltage broadcast".
10.★ Built-in U section teaching wireless microphone and wireless receiver module function
11. Pen shape wheat body design, comfortable to grip, ergonomic; The same microphone can be used in any classroom, and do not interfere with each other, truly achieve one teacher one wheat, clean health and environmental protection;
12. Working band: UHF license-free ISM green band. 24kHz sampling rate is adopted to ensure the high-fidelity effect of human voice.
13. Host and microphone automatic pairing connection distance ≤3 meters, pairing connection time ≤3 seconds; Automatically enter the pairing state. After the pairing is successful, there is a prompt tone, and automatically enter the receiving state. Ensure the product does not cross frequency, strong anti-interference and transmission stability.
14. To achieve encrypted transmission, the receiver supports automatic sweep function to easily avoid interference.
15.U section teaching wireless microphone built-in microphone and external microphone, support volume adjustment, memory function, support one-click mute function; Built-in microphone reverberation function; With laser pointer and PTT page turning function.
16. Built-in rechargeable polymer lithium battery, supporting work while charging; Charging with MicroUSB port, universal mobile phone charger 2 hours of sufficient power sustainable life ≥8h.
17. Compatible with any network structure such as router, switch, bridge gateway, Modem, Internet, 2G, 3G, 4G, 5G, multicast, unicast, etc.
18.★ Mains wide voltage power supply + zero switching time DC24V backup power supply, for the terminal 7x24 hours to provide the best energy supply.
