Digital processing and transmission technology
The system's signal processing and transmission is based on digital
processing and transmission technology. The device uses twisted-pair cable
to transmit high quality digital audio signals, control signals and other
signals.
1.3 System features
The design of the digital conference system has always been based on
the high reliability of the system as the core, which has realized the overall
control of the process of the conference, which mainly embodies the
following:
System advancement
Digital conference system and conference attendance system, intelligent
central control system to achieve a seamless connection, which has been
the first in the industry to provide a comprehensive and efficient solution to
the modern conference system.
System operability
By accessing the system to computer, the operator can implement a more
comprehensive meeting control with the digital conference system software.
With the help of the enhanced microphone management provided on the
conference central controller, the establishment of representative meeting
management control functions such as representative data, attendance,
conference data processing and release, voting management and output
audio processing. Digital conferencing system software can also be
designed according to customer requirements, more attentive to customer
service.
Digital conference system software adopts the client/server mode, the
operator can flexibly operate in the same PC, can also be on the same
network of different PC for the implementation of control, to achieve the
basic meeting management control to ensure the continuation of the
meeting. 1

Digital Conference System
System expandability
The digital conference system is available in both Chinese and English
languages to meet the needs of international conferences. Simultaneous
transmission unit can automatically control the distribution of language
channels, interlock and line scheduling, to ensure that the language channel
signal independent output, to avoid interference and crosstalk.
The meeting units of different conference systems are joined together to
build up any form of conference system, and the established system can also
join more conference units.
Each conference unit has a unique ID number that can be easily installed
and avoid duplication of ID numbers.
Twisted-pair cable connection to facilitate the installation and removal of
the system.
