2.4G Infrared Wireless Video Conference System

SXA-8080

2.4G Wireless Conference Host

Main functions and characteristics:

In line with IEC60914 international standard, 32-bit industrial embedded processor with high performance ARM Cortex A8 is adopted. Its main frequency is up to 800MHz and 256M memory. The system has strong stability and fast operation speed.

U uses 2.4 G full digital wireless transmission technology, ISM band.

U wireless adaptive frequency hopping technology, forward error correction and retransmit mechanism, has the characteristics of error concealment.

Ultra-strong anti-jamming ability, anti-mobile phone interference, even in the conference venue with mobile phone signal shield can also be used normally.

U uses 128-bit AES Rijndael encryption technology for secure wireless communication, which has strong confidentiality.

U is connected with wireless signal base station by 6-core DIN line, and the transmission distance can reach 150 meters.

U pioneered the seamless compatibility technology between wireless conference system and wired system. The wired conference unit and wireless conference unit can be mixed into the system host.

U built-in digital audio processing module of DSP can effectively ensure the smooth and orderly transmission of information and instructions within the system, thus eliminating interference, distortion, crosstalk and other phenomena to the greatest extent, and achieving CD-level sound quality.

U system mainframe supports dual hot backup, which is stable and suitable for large conference center applications.

U boot unit automatic detection, can customize the number.

U has built-in adaptive feedback suppressor (AFC), which can effectively prevent screaming.

U Built-in ambient noise canceller (AEC) can effectively eliminate local noise.

U has built-in digital equalization circuit, which can greatly improve the sound pressure level of the venue.

U is the first 4.3-inch full-color touch screen with bilingual information display in Chinese and English. It has dual functions of system navigation display and centralized control.

U adopts ID addressable control mode, and can access up to 4096 wireless conference units.

U supports cable conference unit access, 5 microphone output, single host can be mixed access to 150 cable digital units.

U supports 48 kHz audio sampling frequency, and channel frequency response can reach 20 Hz to 20 kHz.

The U host can centrally adjust the output gain of the conference unit and set the audio adjustment lock.

U host and computer use TCP/IP connection mode, host and host use five kinds of network connection, RJ45 interface.

U can realize remote control, remote diagnosis and upgrade of conference system. After-sales and technical support can be completed without reaching the project site.

U built-in multi-channel internal communication function.

U system can be centralized controlled and managed by central control system and conference management software.

U Multi-mode conference room merging/splitting function.

U system can be connected to other capacitive microphones or movable coil microphones to provide users with more choices.

U can transmit 1 + 20 channel voice to each speech unit, and has 1 + 20 channel analog output interface, which facilitates the connection of infrared voice distribution system and audio recording equipment.

U has RCA and Kayenn audio input interface, and can input external audio signals (such as background music, wireless microphone).

U has many groups of audio channel output. It can connect PA power amplifier to amplify the speaker's speech. It can also connect recording system, teleconferencing system and so on.

U Speaker Limitation Function: Limit the current maximum number of speaking units. When the speaking units reach a fixed value, to open other speaking units, we must first close the opened speaking units. The number of speaking units is adjustable by 1/2/3/4/5/6, and the executive chairman is not limited.

U has central control interface, PC interface and touch screen interface. It can read control instructions and status of management software, central control, touch screen, ipad, mobile phone and other devices, reflecting the era of modern science and technology conference.

U with telephone coupler can conduct teleconference.

U cooperates with network conference software and video conference terminal to realize remote video conference.

U built-in international general power supply, 100 ~ 240 automatic switching.

U built-in power supply voltage stabilization system, even in areas of unstable voltage can also be used safely.
