In October, 2016, background music broadcasting system and professional audio system of meeting room of haier central air-conditioning interconnection factory used DSPPA and RVS series of audio equipment of our company.

Haier central air-conditioning interconnected factory, located in Qingdao sino-german industrial park, is the eighth of haier's Internet factory, is the world's first maglev central air conditioning smart + connected factories, which can realize interconnection, the interconnection of information and the actual situation inside and outside of interconnected, creating customization needs for global users. According to the different functions of the working area, office area and three meeting rooms in the factory, we have made a reasonable configuration plan.

In the workspace and office of the building, the background music system is using 1 MP9907C player for the external audio source, but it can read the disc and the flash drive, and the first stage amplification MP9811P is connected to 2 MP4000 pure back class, and it's connected to 2 MP9813D partition, and the police can take the fire signal in the precinct. In addition, the other end of the partition is equipped with an MP9812M listener, with built-in active listening horn, which can be accessed and adjusted at will. The system's back end speakers use 53 DSP403 sound pillars (workspaces) and 21 DSP106 speakers (offices). An MP9823S power timing device is also provided for convenient operation of the protection circuit.

The main equipment used in the conference room is RVS professional equipment.

The speech subsystem USES an AQTA v-99 wireless microphone. The timing power controller USES a DSP MP9823S. In addition, there is one F10.2 tuning platform in conference rooms no.2 and no. 3, and then one ds-24 is connected. Through one pd-300 power amplifier, two RVS MR512 dual 12-inch full-frequency speakers are driven to sound.
