All 5 products submitted by BXB in 2015 won the Taiwan Excellence Award, marking the third consecutive year of recognition by Taiwan Excellence. Among them, the new FCS series conference system main units and units accounted for four of the awards. The new conference system incorporates many innovative concepts in conference system application, integrating numerous functions such as AGC (Auto Gain Control), TCP/IP protocol network control, and mobile app control, blending IoT and cloud processing technologies into the management and application of conference systems. BXB has also put a lot of effort into the cabling of the conference system to achieve a more flexible solution that meets customer needs. The following explains the cabling methods of the conference system and their advantages and disadvantages.

Currently, the wiring architecture of conference systems from many manufacturers usually uses a daisy-chain (hand-in-hand) wiring method for series connection. In terms of connection, it connects from the first unit to the last unit according to the allocated number of units in different loops. This wiring method is simple and saves cable usage. However, the daisy-chain wiring method has its flaws. Taking the third microphone in the top row of the figure below as an example, once there is an abnormality in the line between the first microphone unit and the second microphone unit, or if the second microphone unit breaks down, it will cause the subsequent units in this loop to fail to function properly.
