The Exigo Network Amplifier is designed for use in marine, offshore and other demanding environments. The amplifier utilizes state-of-the-art class D amplifier technology to ensure high power efficiency and superb audio quality.

The Exigo Network Amplifier is part of the Exigo PA/GA system, which is based on standard Ethernet network and digital processing. Each amplifier has two network connections, allowing for redundant cabling between the amplifier and the network. Using standard network equipment also allows for a much wider selection of standard network equipment.

The digital audio processing and maintenance of the amplifier is done with the embedded CPU and DSP. These components allow the amplifier to do advanced audio processing such as automatic gain control and equalizing while also maintaining a robust connection to the system controllers.

The complete amplifier is self-monitoring and this includes advanced monitoring of the speaker lines and internal system. The audio output channels can be monitored for line faults such as shorts, ground faults and large load changes. In addition, up to 10 intelligent Line End Transponders (ELTSI) can be placed on the speaker lines for additional accuracy in the line monitoring. The amplifier also monitors control inputs, power supplies, temperature, network connections and every other components required for operation of essential services. Faults will be reported to the system controller, but will also be indicated locally on the amplifier.

Amplifier supports "One Channel Mode". When "One Channel mode" is activated, the two loudspeaker channels will play identical audio, and the audio will be in phase.
One can then choose to use two separate loudspeaker loops, each with maximum 400W, or one can bridge* the two output channels, and use one loudspeaker loop with up to 800W load. *) Note: Speaker line surveillance not supported in bridged outputs setup.

The amplifier’s configurable control inputs/outputs and audio input can be used locally by the amplifier or can be controlled by the system (e.g. audio input for background music). The audio line input can also be configured in a Hardware Bypass mode where audio on the line input will be forwarded to the 100V channels directly, even when no server is available. This allows for additional redundancy and functions to be built around this amplifier.
