System Description
The dual-system dual-backup digital conference system implements the expansion of basic discussion and more conference functions, fully integrating unique digital technology, network technology, and digital audio technology to achieve high-speed data transmission under high bandwidth conditions, thereby further improving the microphone's fidelity and sound transmission speed, reducing audio loss, and ensuring high-fidelity audio quality of the microphone; at the same time, it uses a shielding system and high-speed DSP modules combined with digital frequency shifting technology and suppression technology to control howling, immune to high-frequency noise, environmental noise, and electromagnetic interference, presenting perfect sound quality to users. It can seamlessly connect with intelligent central control systems and video conferencing systems, providing a complete solution for efficient modern conference system projects.
Functional Features
▲ Uses dual-system dual-backup multi-channel system unit connections and can back up ring connections, with four 8-core dedicated conference unit connection ports, four RJ45 network cable connection ports, each supporting 30 units, with up to 6 chairman units, allowing a maximum connection of 120 conference system units, and can connect to expansion hosts and conference repeaters, supporting the simultaneous use of up to 1000 conference system units;
▲ Innovative high-speed embedded digital hardware architecture processing and transmission technology, compatible with IEC60914 and GBT15381-94 standards, achieving unprecedented levels of system operating speed and stability;
▲ Full digital audio processing technology, processing all channels' sound to CD quality, effectively preventing feedback and interference, ensuring perfect clarity, privacy, and security of the conference audio;
▲ Conference units can use either super category 5 (category 6 or 7) network cables with RJ45 crystal heads or 8-core dedicated conference cables, depending on user environment needs, effectively resisting interference, making installation more convenient, and ensuring more reliable transmission;
▲ When the conference unit uses a ring circuit connection method (1 output 1 backup input), even if the intermediate connection line or conference unit fails, it will not cause the system to crash or paralyze, ensuring the system can be used efficiently and normally;
▲ The system operates at a low voltage DC 24V safe voltage, ensuring user safety, low energy consumption, high safety, and being environmentally friendly;
▲ Uses 32-bit high-speed DSP floating-point processing, with high bandwidth, featuring acoustic feedback suppression, echo cancellation, noise cancellation, digital equalization effects, and automatic gain;
▲ Equipped with a 1.77-inch true color display screen, showing system menus and host status information, allowing centralized control of all conference functions through the panel navigation keyboard;
▲ The system host has a password lock screen function, facilitating user management needs;
▲ Supports USB recording, high-fidelity WAV format output;
▲ The system has an automatic repair function, supporting hot-swappable lines;
▲ The maximum distance from the system host to the conference unit can reach 150 meters;
▲ All conference units have real-time display of usage status, and when the indicator light is on, the microphone can be used to speak;
▲ Has a power-off automatic memory function, allowing use without needing to set it again after power is restored, and can restore factory settings;
▲ Conference speaking modes available: FIFO (First In First Out mode), FREE (Fully Open mode), C-ONLY (Chairman mode), i-LIMIT (Limit mode);
▲ 1 XLR audio output interface, 1 6.35mm audio output interface, making system connection to audio systems more flexible;
▲ Internationally universal wide-adaptive power supply design (AC100-240V 50/60Hz), suitable for any country and region;
▲ International standard 2U panel size, can be installed in a 19-inch standard rack, easy to store and manage.
