Guangzhou DSPPA Audio Co., Ltd.

D7201 5G WiFi Conference System

1. Solution Description
For the transformation of old conference rooms, such as multi-function halls, on-site release halls, and temporary conference venues, using the wireless conference system has great advantages, which can quickly and easily build and remove the conference system, and it is not required to damage the site layout.
With the development of touch technology and the advent of the mobile Internet era, almost everyone has a touch screen mobile phone, and the coverage of WIFI Internet makes communication more convenient and direct.
Based on touch technology and WIFI communication technology, DSPPA successfully launched the 5G WIFI wireless conference system researched and developed independently. The design of the conference unit has independent appearance patents and the original curved touch screen not only increases the viewing angle, but also conforms to ergonomics, enhancing the texture and the sense of technology.

4. System Functions
1. High confidentiality encryption technology and highly reliable transmission technology
It adopts128-bit AES encryption technology, and supports WPA/WPA2 wireless security technology, to guarantee the confidentiality of meeting information. Using the 5GHz communication frequency band, it has stronger bandwidth and communication speed, with good resistance to electric wave and electromagnetic interference, for faster and more stable wireless signal transmission.
2. High-fidelity sound quality, low-latency transmission
It adopts uncompressed audio transmission technology, with 20Hz-20KHz perfect sound quality, 48K sampling rate; The exclusive Dante no-latency conference system seamlessly integrates with the 5G WiFi wireless conference system, which can be used with any Dante device.
3. Abundant application functions
The device supports both wired conference unit and wireless conference unit, with wireless and wired conference sign-in, conference speech, voting, speech timing, camera tracking, fire linkage, short message broadcasting, and tea application, time display, conference recording, countdown and applying for speaking.
4. Simple structure and powerful load capacity
One D7201 host, one WiFi transmitter host, and multiple wired and wireless conference microphones can form a wireless WiFi conference system. It can support ≥ 4096 wired conference units, and ≥ 300 wireless conference units more to access, and the device has a carrying capacity of up to 5,200 seats, for unified management and data processing in the background. It can be equipped with 6 high-definition cameras at the same time for automatic conference speech camera tracking.
5. Noise suppression processing:
The host is embedded with a high-performance quad-core CPU processor, adopts soft mixing digital audio processing technology, and has an ARM7 processing chip to effectively prevent sound from returning. The microphone has a built-in high-fidelity speaker, which is automatically muted when the microphone is turned on, and it is not easy to produce howling, ensuring the quality of the meeting; with 7-band EQ adjustment function (can be adjusted on the PC software), it can adjust different sound effects according to the voice characteristics of the speaker for a perfect effect. Besides, it has noise gate ANC control which can identify the human voice, AGC automatic gain control; and AFC automatic feedback cancellation.
6. Fast charging & super battery endurance life
The conference microphone adopts a large-capacity battery with long battery endurance life. The battery supports fast charging, which can shut down all WiFi units with one button, master real-time information and comprehensive hardware monitoring.
7. PC terminal control and monitoring functions
Supporting TCP/IP protocol, all functions of the system can be controlled through PC software, and status information such as WiFi signal strength and battery power of the conference unit can be obtained in real time.
8. With dual-system hot backup function
One conference host can be set as the host, and the other conference host can be set as the slave, and connected to the system. When the host encounters an accident, the slave will be automatically activated to ensure uninterrupted smooth progress.
9. 2.4" OLED display and online remote upgrade
The microphone can display WiFi signal strength, battery power, unit information, speaking timing and other status, and the host and unit support online remote upgrade functions to meet the needs of customers for later function customization, product maintenance and function optimization, which is easy for maintenance.
