IP network microphone features:
1 professional paging microphone appearance, start-up time ≤ 1 second, with TFT true color LCD screen, 20 buttons and lights.
2. With a microphone directly input, the area allowed for permission to broadcast speech (with prompt tone), red warning light, call automatically light;
3. Built-in speaker, call the terminal (or accept terminal calls), to achieve two-way conversation;
4. Can expand multiple partition selectors, each partition selector has 8 keys.
5. Access is available where there is an Ethernet port, supporting cross-network segments and cross-routes.
It can be accessed anywhere there is an Ethernet port. It comes with a dual hub (HUB) that allows access and control of servers and other IP network devices.
Network failure self-diagnosis, network and service status display.
With one line output, the digital audio on the network can be converted into analog audio signals, which can be connected to ordinary analog analog amplifiers.
The power management function, with an external power control port, can automatically control the power on or off of external power amplifiers or other devices, enabling intelligent power control and unattended operation.
There are two microphone input ports with different sensitivities to facilitate users to access high-sensitivity conference microphones, wireless microphones, or ordinary wired microphones with low sensitivity.
With one line input port, you can access external analog audio source devices such as timer players and CDs.
Strong cut function, when there is a signal input (mike signal or line signal can be), can automatically open the appropriate power amplifier or terminal, broadcast to the specified area.
You can set strong priority, choose microphone priority or line priority.
Output signal indicator.
Chinese display, real-time display of machine status, source volume, song name.
Single-key shuttle, convenient and quick operation.
IP network microphone system advantages:
Stronger features: A pure digital broadcasting system covers all the functions of a traditional campus broadcasting system. And to achieve audio on demand (AOD). And make full use of the resources of the campus network, can access the audio resources on the network anytime, anywhere. Since each terminal has a separate IP address, it is possible to control any terminal to play different programs.
Better sound quality: Due to the use of network transmission technology, audio signals are free from interference and distortion. Using MP3 compression algorithm occupies low network bandwidth (8k-128k) and guarantees fidelity of sound quality. It has been tested using 44.1khz 16bit sampling 128kbps rate compression passband (line output) 20-16khz, distortion ≤ 3%
Higher reliability: The unstable factors of the campus broadcasting system mainly depend on the quality of transmission lines, unreasonable transmission lines or causing instability or even burning high-power constant-voltage power amplifiers. Pure digital broadcasting system Thanks to the mature Ethernet communication technology, each terminal equipment is equivalent to a simple computer connected to the campus network. Users only need to ensure the smooth flow of the network without adding any additional maintenance.
More convenient and flexible, and more able to meet the teacher's requirements "Play broadcast without having to be in a fixed broadcast room, as long as the installation of the playback software and encryption and authorization can be implemented on their own computer within the permission of the broadcast, but also to meet the needs of outdoor instant broadcast, function Closer to the teacher's requirements, it greatly compensates for the features that cannot be achieved by traditional broadcasters. The broadcast base brings handy management tools to management.
A Concrete Mixer (also called a cement mixer) is a device that homogeneously mixes cement, aggregate such as sand or gravel, and water to form concrete for construction by the revolving drum. For smaller volume works, portable concrete mixers are often used for its compact and lightweight appearance and high efficiency at the construction site, giving the workers ample time to use the concrete before it hardens. Classified by the power type, we have electric concrete mixer and diesel concrete mixer for choice.
Functions of Concrete Mixer:
1. Uniform the components in macro and micro
2. Destruction of cement particles and promote the development of dispersion
3. Destroys the initial hydrated film coating of the cement particles surface.
4. Promote collision and friction between material particles and reduce the impact of dust film
