Simultaneous interpreting host QT-B720M

The system host has the functions of speech discussion, meeting attendance, service call, video tracking, table display, voting, simultaneous interpretation, etc, The imported original DSP chip and qtdsp-dpt digital audio processing technology are adopted. The audio sampling frequency is up to 48Khz, and the frequency response is up to 30Hz-20KHz, similar to the effect of CD sound quality. The standard cta5 network cable is used between the host and the speaking unit, which can be connected in either the "hand-in-hand" mode or the "ring-shaped hand-in-hand" dual machine backup mode. When the system host fails The backup host immediately starts the takeover to ensure the normal progress of the meeting, so that the system has a higher stability.

Qituo has broken through the traditional technology, provided more excellent anti-interference shielding ability, and effectively avoided 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 system host has the functions of speech discussion, meeting check-in, service call, video tracking, table display, voting, simultaneous interpretation, etc

★ standard CAT5 network cable is used to connect the system host and speech unit

★ the system host can also be connected to the third-party switch and speech unit for voice data communication

★ the system host has digital audio output, which is convenient for lossless transmission with other digital audio equipment

★ the system host has Dante digital audio output, which is convenient for voice communication with other Dante audio devices

★ the system host has optical fiber input and output

★ the host of the system has the function of using wireless conference and wired conference at the same time. Adding an AP wireless router can form a wireless + wired conference system and run the same system

★ the system host can adjust the gain and balance of each speaking unit (5 segments)

★ the audio output of the system host has 5 sections of equalization which can be adjusted

★ the system host has the function of ring-shaped hand-in-hand connection and dual backup. When the system host fails, the backup host immediately starts the takeover to ensure the normal progress of the meeting

★ the system host and microphone can carry out internal text communication short message for the convenience of information transmission during the meeting

★ edit the names of participants on the system software, and the front screen and back screen of the speaking unit can synchronously display the participants' exact positions

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

★ audio signal is processed by special high-performance DSP, supporting 48Khz audio sampling frequency

★ the system software has multi-level permissions for microphone (different permissions are assigned to the chairman, VIP, representative, etc. according to the nature of the position)

★ the system host has built-in equalization to adjust the system output signal to meet different meeting occasions

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

★ 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

★ built in four-way video switching, can be configured with four high-speed pan tilt cameras, through preset, can track the video of speech microphone, external HD video matrix can be linked with HD camera switching (no limit to the number of cameras)

★ the IP address of the system host can be modified, and the advanced TCP / IP connection control mode can be used between the host and the control computer to realize the remote control, remote diagnosis and remote upgrade of the conference system
