Background music Application scenarios: Coffee shops, western restaurants, shopping malls, stadiums, supermarkets, etc. Background music can be used to create a harmonic auditory atmosphere for coffee shops, supermarkets and shopping malls. It is widely used in modern intelligent and multifunctional buildings. As such place has a large area and many partitions, partition-based control and long-distance transmission shall be achieved. The control room is equipped with a TIGER D88S processor for partition-based broadcasting of call station and player; based on the use requirements, each partition is equipped with PoE full-frequency speaker or PoE ceiling speaker. Besides, each partition shall also be equipped with a touch control panel, which can be used to independently adjust the volume of the specific partition.

Conference Center System A conference center generally consists of many conference rooms, so it is not easy to exert control over them. Besides, audio interconnection shall be achieved for multiple conference rooms. Therefore, we shall adopt distributed processing, centralized control and network transmission schemes. The control room is equipped with a Dante server DCORE 6464 for master control, while small conference rooms are controlled by the control room through DBOX-I. Other conference rooms are equipped with DBOX-H or TIGER D88S according to the audio quantity and functional needs. The audio signals for all conference rooms are interconnected through internal network, and the control room conducts scheduling and moni- toring on all audio signals of the entire conference center.

Government Assembly Hall of Long- gang District, Shenzhen City Customer needs: The devices in the original government assembly hall were all old analog devices. It took a lot of time to debug them before each conference, and lots of personnel are required to guarantee the smooth implementation of the conference. Not only that, squeak and feedback often occurred, and the speaker also suffered delay. The customer did not want to replace the analog devices. Under the circumstance that the original decoration could not be demolished, there was a high requirement for onsite wiring. Solution: 2 TIGER D1616N and 8 DPanel microphone panels are adopted to solve the squeak and feedback problems as well as the existence of too many emitting surfaces. By adopting our auto delay calculation function, the original analog amplifiers and speakers are all replaced by amplifiers and speakers with Dante interfaces. The original analog micro- phones are retained. 8 Dpanel microphone panels are used to get the original analog microphones accessed to new control rooms in the long distance through IP connection. Besides, echo cancellation function is added to prepare expanded audio interface for video conference access. -52-
