Network paging microphone D-7702

1. Desktop design with built-in 7-inch touch screen control. Humanized operation interface, clear display, and sensitive touch. Enter sleep mode and power-saving mode when there is no operation

2. Designed with embedded computer technology and DSP audio processing technology, this high-speed industrial grade chip has a startup time of less than 1 second.

3. Support paging for single or multiple regions or the entire area. Support direct paging or intercom with terminals, support environmental monitoring of any terminal, with a distance of up to 5 meters.

4. Supports full duplex two-way intercom function and comes with a network echo cancellation module. Bidirectional intercom between IP terminals, with a network delay of less than 40ms, effectively suppressing network echo and howling.

5. Built in MP3 decoding module, capable of displaying song names, supporting playback functions such as previous song, next song, play, pause, stop, single loop, all loop, etc., for easy operation and control.

6. Support for help signal ringtone, flashing light prompts, one click acceptance of help, intercom function, as well as hands-free calling and receiving broadcasts for quick connection.

7. Equipped with an emergency call button, when there is an urgent emergency, pressing this button will promptly activate the broadcast warning.

8. Built in 1 network hardware audio decoding module, supporting TCP/IP, UDP, IGMP (multicast) protocols, realizing networked transmission of 16 bit CD sound quality audio signals.

9. Built in 2W full frequency high fidelity speaker output, enabling two-way communication and network monitoring.

10. One audio line output, external expansion power amplifier; One audio line input, providing multi source transmission.

11. This terminal is equipped with a priority output adjustment knob for the microphone and line, which can be adjusted to set the microphone to the highest priority or output at the same level as the line.

12. One alarm triggers short circuit output, cascading external expansion warning equipment or controlling access control; One way short circuit input can be used to trigger preset voice prompts (or alarms), and can also be used to control access control linkage input short circuit signals.

13. One way USB input, with built-in USB flash drive function. The USB flash drive automatically writes the IP address and plays music programs directly from the USB flash drive locally. The music in the USB flash drive can be converted into network data streams and transmitted to other terminal devices.

14. High fidelity recording function, which can record high-quality signals from microphones and line inputs. The recording files are stored on the server and can be played at any time
