According to the actual installation of sip speakers, we can choose different types of speakers, such as column speakers and wall speakers. Also need to prepare network switch, fiber optic transceiver, splitter, sip intercom, shift room phone, dispatcher, sip serve, power amplifier, several network cables and audio cables. The first to use switch, all the office phone and sip server connected to the optical transceiver, the use of optical fiber transmission signal over a long distance, then the network switch connected to the optical transceiver, connect the emergency intercom network switches, borne power amplifier is connected to the emergency intercom, then sip speaker is connected to the amplifier. The safe transmission distance of network signals is 100 meters, and over 100 meters, fiber optic signals are selected for transmission. One area, choose 1 network switch, the intercom phone below the switch does not exceed the network interface of the network switch.

Advantages of school pa system with integrated system
