The network amplifier ENA2400 is designed for use in demanding marine and offshore environments. The construction is extremely robust, and can handle mobile environments as well as stationary, temperature controlled rooms. The amplifier utilizes state-of-the-art class D amplifier technology for superb audio quality and high power efficiency.
The amplifier connects to the Exigo system through native IP networking, and receives audio and control data, through standard 100 Mbps Ethernet. The design com prises two Ethernet connections, enabling redundant cabling between the amplifier and the network. The amplifier has DSP capabilities, allowing advanced functions like audio equalization and audio delay. The DSP is an integral part of the audio synchronization between all audio outputs in the Exigo system and alarm tone generators.
The amplifier monitors the speaker lines for shorts, overload and opens. A Line End Transponder (ELTSI-1) is required for reliable detection of an open or shorted line when the cables exceed 400 meters. More than one ELTSI can be connected to the same line, allowing monitoring of several branches on the speaker line. The amplifier also monitors control inputs, power, temperature, network connections and every other component required for reliable operation of essential services. Faults will be reported to the system controller, but will also be indicated locally on the amplifier.
The amplifier’s control inputs/outputs and audio inputs can be used locally by the amplifier (e.g. for PTT and audio from a handheld microphone) or they may be controlled by the system itself (e.g. audio input for background music).
