D6801 2.4G Wireless Series Conference System


What is 2.4G wireless transmission?

The 2.4G wireless technology is a short-range wireless transmission technology for open source use.The 2.4GHz refers to a work frequency band, 2.4G Hz ISM (Industry Science Medicine) is a wireless frequency band that is publicly used all over the world. Bluetooth technology also works based on this frequency band.

The 2.4G wireless technology can obtain the advantages of  bi-directional propagation, strong anti-interference, long transmission distance (short-range wireless technology range), and low power consumption, which are widely used in household and commercial fields.

2.4G Wireless Conference System Highlight Functions



1. Wireless encrypted transmission:
Using mature 2.4GHz adaptive frequency hopping spread spectrum (ADFHSS) technology, it has good confidentiality and strong anti-interference ability to prevent eavesdropping and unauthorized access, and provide higher confidentiality of the conference system.
2. Abundant application functions:
The system adopts 2.4GHz wireless transmission, and supports four conference speech modes: FIFO, NORMAL, Free, and APPLY, but the chairman mic has the priority to speak. It can be moved and used arbitrarily within the range of signal coverage, and can support 255 mics for connection.
3. Video signal processing function:
It adopts a 120" main projection screen, an engineering projector with a brightness of 6500lux, and 2 cameras D6283II and other display devices to realize the coordination, processing and switching of input and output signals. The input signal can be switched and combined in the D6108 video matrix at will to realize a very flexible signal central processing function.
4. Camera tracking and anti-interference signal ability:
The system has the real-time video tracking function, and it can support 4 channels of video signal input, and 2 channels of video signal output. Besides, it has the function of automatic detection of interference signal. When an interference signal is found, it will allocate a frequency that can avoid the interference signal for use.
5. Sound reinforcement system
In terms of sound reinforcement, it focuses on the clarity of speech sound reinforcement, sound transmission gain, sound pressure level, sound field uniformity, and music playback sound quality. In addition, professional audio processing equipment makes the voice clear, distortion-free and no feedback howling.
In this conference system, when the delegate mics D6802L and D6803L speak, the audio is sent to the mixer MG12 after being processed by the host D6801, and then to the processor D6575, to the amplifier MX1500II, and to the speaker D6563, so as to achieve local sound reinforcement;
4 speakers D6563 enable sufficient on-site sound pressure margin, uniform sound field, and accurate sound image positioning.
6. Intelligent power management system and automatic frequency lock
It adopts the intelligent power management system. After the host is turned off, all mics will automatically shut down to reduce battery consumption.
The speaking mic has automatic frequency tracking and has no need for complicated frequency pairing operations.

The connection methods between the host and the antenna

A. Host + Omnidirectional Antenna



In an open environment, connect the 2.4G host to an omnidirectional antenna, with the straight-line distance of ≤30 meters.  The omnidirectional antenna must be vertically upward (as shown in the figure).
