4.System Functions
● Simple structure and powerful load capacity
A wireless WiFi conference system consist of a D7201 host, a WiFi transmitter, and multiple wired and wireless conference microphones. It has a carrying capacity of up to 5,200 seats for unified management and data processing at the background.
● High confidentiality encryption technology
It adopts 128-bit AES encryption technology, and supports WPA/WPA2 wireless security technology, ensuring the confidentiality of meeting information
● Highly reliable transmission technology
Using the 5GHz communication frequency band, it has stronger bandwidth and faster communication speed, with good resistance to electric wave and electromagnetic interference, securing faster and more stable wireless signal transmission.
● High-fidelity sound quality, low-latency transmission
It adopts uncompressed audio transmission technology, with 20Hz-20kHz perfect sound quality, 48K sampling rate; The exclusive no-latency Dante conference system seamlessly integrates with the 5G WiFi wireless conference system, which can be used with any Dante device.
● Noise suppression processing
The host, embedded with a high-performance quad-core CPU processor, adopts soft mixing digital audio processing technology, and uses 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, it will not produce howling, thus ensuring a quality meeting.
● Fast charging & super battery endurance life
The conference microphone adopts a large-capacity battery with long endurance. The battery supports fast charging. All WiFi units can be turned off with one button; The system makes it possible to master real-time information and comprehensive hardware monitoring.
