Business talks, product demos, guest meetings, government orders, etc. all require use of "meetings" to solve problems. Today's conferences require high-quality audio signals, dynamic video and high-definition images, physical data, accurate data expression, and a simple and practical control system to facilitate all operations.
A modern conference system can realize
01
Digital integrated central control system, broadcasting system, public address system, remote video conferencing, computer network, simultaneous translation system, video and audio technology of camera editing system are integrated into one.
02
All aspects of system can control various equipment in room and display various information such as DVD, TV, video cassette, CD, computer, on-site camera signal, manuscript, slideshow, photograph, physical object, letter , remote conference, etc. on big screen on screen.
03
Simultaneous interpretation system can perform simultaneous translation into multiple languages, synchronize sound and image, transmit confidentially and real-time multi-channel digital voice system.
04
Control environment in room. For example, directly dimming ceiling light, turning on and off fluorescent lamp, switching curtains, raising and lowering screen, etc. It can also set various control modes through pre-programming, and control multiple functions at same time, so that various distributed systems in room can be seamlessly integrated into one management system for centralized management and control, and overall application environment can be upgraded to a brand new intelligent mode environment.
05
Adaptation to computerization of office automation; combining network structure of each block; clear and bright visual information; realistic and vivid sound effects; convenient, fast and complete meeting recordings and transfer forms; comfortable indoor environment; simple and smooth meeting process.
Design principles for conference and sound reinforcement systems
01
Design principles for a modern conference and speaker system
Expanded and scalable
With development of modern information technology, new products and new technologies appear in an endless stream. In this way, system makes full use of modern mature and stable technology, on condition that investment costs allow, so that system can adapt to social development as long as possible.
Scientific and normative
The conference and public address system is a complex integrated system project. It should start with system design, including construction, installation, commissioning and entire final acceptance process. It must be made in accordance with relevant national standards and specifications. Systematic standardized design and scientific management.
Safety and reliability
The design of conference system and public address system directly affects use effect and appearance of user, so design of system must be safe and reliable. Adopt mature technologies and products to minimize chance of failures in hardware selection and system design. And it meets reliability requirements in terms of laying lines, installing equipment, debugging system, and technical training of Party A personnel.
Economy
Assuming an advanced, reliable system with a high performance-to-price ratio, most economical goal is achieved through an optimized design.
National standard for audio amplification systems for conferences
According to National Enrollment Hall Sound System Design Standards Characteristics: maximum sound pressure level in a steady quasi-peak empty field state
a. The first-class language amplification system standard should be 90dB
b. The main standard of language and music sound reinforcement system should reach ≥95 dB
c.Sound field unevenness must be ≤8 dB at 1.0 kHz and 4.0 kHz
d.The average value of audio transmission gain at 0.125~4.0kHz should be ≥-8dB
