Translation unit QT-T721c / D

       The network type digital conference system has practical functions such as speech discussion, conference check-in, voting, call service, video tracking, etc.

 

Qtdsp-dpt digital processing and transmission technology with independent intellectual property rights is adopted, and superior digital audio technology and digital network technology are fully combined. The digital audio technology and network technology are systematically applied to the conference system.

The network type digital conference system breaks through the traditional technology in the past. The standard network cable hand-in-hand connection is adopted between the system host and microphone, and the ring-shaped hand-in-hand connection dual computer backup function is supported. The conference system and sound reinforcement equipment can also be interconnected through the exchange unit network.

It can realize the seamless connection of digital conference microphone with wired and wireless modules, dual channel backup, wired and wireless signal switching, and the signal will not be interrupted during the switching process.

Using qtrf-derfi digital electromagnetic radio frequency anti-interference technology of qituo, the new anti-interference algorithm, advanced circuit design and overall optimized deployment of audio transmission signal are carried out. More excellent anti-interference shielding ability. It can effectively avoid electromagnetic interference such as mobile phone, WiFi, Bluetooth, wireless base station, radar signal, microwave signal, FM broadcast and complex computer room environment.

Product characteristics

★ the microphone and the conference host are connected by the standard CAT5 network cable hand-in-hand mode

★ the microphone and the conference host can also be connected to a third-party switch for voice communication

★ the microphone has a digital identification code in the conference system, and the signal stream can be output to the third-party voice system for recognition (optional)

★ it has the functions of speech discussion, meeting attendance, voting, call service, video tracking, etc

★ cardioid directional microphone with LED indicator ring

★ high brightness OLED display, which can display the working condition of microphone and information of participants

★ built in headphone jack, which can be connected to headphones to listen to conference sound

★ built in high fidelity speaker, automatically mute when microphone is turned on, no screaming (optional)

★ adopt qituo qtdsp-dpt digital audio processing and transmission technology to realize complete digitalization of audio

★ the audio signal is processed by special high-performance DSP, which supports 48 kHz audio sampling frequency

★ each microphone can independently adjust the gain and balance (5 segments), and adjust different frequency response according to different speaker's voice characteristics, until the ideal effect is achieved

★ the system has a ring-shaped hand-held double computer backup connection function. When the main control system host fails to work normally, the backup system host immediately starts the takeover meeting to ensure the normal progress of the meeting

★ the system host and microphone can conduct internal text communication (short message), so as to facilitate the information transmission during the meeting (optional)

★ system microphone and system host can realize remote diagnosis and remote upgrade through TCP / IP connection

★ microphone can set multi-level authority (different authority can be allocated according to the nature of the position, such as chairman, VIP, representative, etc.)

★ each microphone can work independently to ensure that the failure and replacement of any microphone in the system will not affect the normal operation of the whole system

★ each microphone has an independent ID number, which is convenient for installation and avoids ID number repetition

★ the microphone is powered by the main unit of the system, and the working voltage is 48V DC, which conforms to the safety standard

★ comply with gb8898-2011 national standard for compulsory certification of audio and video equipment
