      The KNPLC-B1 is designed with a wide set of hardware functions, and can be used as a PA Interface and a Radio Interface. 

      As a radio interface, KNPLC box provides audio and signaling. The unit has a headset connection for listening in on conversations. It features a remote RS232 port for signaling, audio in/out, and 12V radio "On" signaling. 

      As a PA interface, the PLC box provides an audio and signaling interface between PA amplifiers and KNTECH server/ exchange. It provides speaker loop monitoring inputs for each amplifier, as well as additional inputs for the monitoring of PA amplifiers and/ or other system components. The PLC box come with two parallel PA audio outputs, enabling the connection of two PA amplifiers. 

      The PLC box has an integrated managed data switch providing advanced networking and security features. This allow you to deliver efficient, instant, and secure voice and data services in an IP environment. 

      To provide maximum availability, the PLC box comes with advanced supervision functions. The line test will detect if there are any faults in the PLC box electronics or in the network. The status is shown on LED indicators, also can be reported to KoonWeb.
