DSPPA | IP Network PA System for Star River Center in Guangzhou

Abstract: DSPPA IP network public address system has been applied to the office building of Star River Center in Guangzhou.

Project Overview
Located in Guangzhou Pazhou Internet Innovation Cluster, the new economic development engine of the Greater Bay Area, Star River Center is the first super Grade A office building built by the Star River Group with more than 20 years of experience in urban construction, urban services and intelligent applications, upholding the values of “willingness, dedication and innovation”.

The building has a total height of 250 meters, 46 floors above ground, and a total construction area of about 120,000 square meters.

Project Spotlight
The 250-meter super high-rise office building of Star River Center adopts the digital, networked and intelligent DSPPA network public address system, which consists of a network public address host, intelligent paging station, audio output terminals, multimedia player, zone pa amplifiers, wall-mounted speakers and ceiling speakers. It meets the needs of Star River Center, such as background music broadcasting, daily information and notification broadcasting, emergency broadcasting, paging call, and fire linkage.

Automatic BGM Broadcasting
Based on the characteristics of modern business centers, background music is usually set in public areas to create a relaxed, comfortable and pleasant atmosphere. The system is centrally controlled by the broadcast host, and different background music of multiple zones are automatically turned on or off according to the application function of the floor; with rational distribution of ceiling speakers and wall-mounted speakers, all areas of Star River Center are evenly covered by the broadcast. In addition, the system is equipped with a multimedia player for different playback modes.

Emergency Broadcasting
The system provides linkage fire control and one-button alarm. The built-in fire linkage function module of the host works with the fire system of the business center. In case of fire or other emergencies, the broadcasting system will automatically stop playing the background music in the area and activate the alarm broadcast for emergency evacuation broadcast, so as to respond quickly to the emergency and ensure timely evacuation alarm of the business center.

Zone Paging & Call
The paging station or handheld emergency paging microphone of the host can be used to initiate paging and release announcement to a specific area.
