Introduction 1 ZYCOO Co., Ltd Public Address(PA) is typically required for some factories, schools, supermarkets, fitness centers…which will broadcast advertising messages, audio announcements or play background music. However, for factories, schools, supermarkets, or fitness centers, one speaker is usually insufficient to meet the needs of the business as normally there are multiple zones to address, manage and monitor. A perfect PA solution is an essential requirement for enterprises in different industries. ZYCOO Co., Ltd Copyright @ 2015 ZYCOO All Rights Reserved

What industries need PA solution? 2 ZYCOO Co., Ltd What industries need PA solution? Along with the development of the Internet network, high efficiency working is a target that all enterprises are pursuing. What industries need a perfect PA solution?

School: announcement initiated by school leader or campus radio. Supermarket: announcement of sales promotion or emergency announcement… Workshop: normally a factory has many workshops across a large area and this environment can be very noisy, so an announcement from office to workshops is very necessary.

Evolution of PA Solutions 3 ZYCOO Co., Ltd Evolution of PA Solutions Legacy PA solution: can be deployed by non-technical staff, as it is all about cabling and we never need to worry about compatibility with other devices. However, voice quality is lost even using expensive cable and communications over cable are very insecure. It is a high cost but low productivity solution for public addressing, as you have to pay for operating platform and PA specialists to standby and control the system 24x7. IP PA solution: Utilizes TCP/IP protocol, an IP Speaker is deployed on the IP network to provide reliable, fast and automatic announcements and is simple to manage through a standard PC and application. Communication data is secured to reach anywhere in our network or even internet, and offers high definition encoded voice / audio without transmission impairments and distortion of audio signal. The main problem however with this type of solution is that the systems are bespoke and therefore the cost of system maintenance or expansion of the solution is high, as IP devices required are specialized and can only be purchased from the solution provider meaning you pay a premium for them. SIP PA solution: Technically it is a SIP + IP PA solution, and enjoys all the advantages that an IP PA solution has. However, as SIP is commonly used for VoIP, there are a wide range of applications such as computer software or apps on BYOD to choose from. The difference is SIP PA system is compatible with all SIP devices. SIP PA system is the industry trend for its perfect compatibility and performance.
