The Exigo Network Amplifier is designed for use in 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 am plifier technology for superb audio quality and high power efficiency.
The amplifier connects to audio sources through standard 100 Mbps Ethernet. There are two Ethernet connections, making redundant cabling between amplifier and network possible. The amplifier has DSP capabilities, enabling it to do audio equalization and audio delay. The DSP is also an integral part of audio synchronization between all audio outputs in the system and alarm tone generation.
The amplifier operates from a primary 115/230 VAC supply and have automatic uninterrupted switchover to a secondary 24- 48 VDC supply if the primary should fail. The amplifier will continue to operate with full service during and after the switchover.
Each audio channel features separate line level inputs, allowing backup amplifiers to take over operation of the speaker loops in the event of critical faults.
The amplifier monitors the speaker lines for shorts, overload and opens. A Line End Transponder (ELTSI) is required for reliable detection of an open line. 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 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 can be controlled by the system (e.g. audio input for background music).
