Exigo Network Amplifier
- 2x 400 watt continuous GA effect
- 2x 400 watt PA effect
- Power efficient class D technology
- Powered by 110 - 230 VAC
- Redundant Ethernet connections
- Digital audio processing, equalizer and audio delay
- Loudspeaker line monitoring
- Input for backup amplifier
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 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.
The amplifier operates from a 115/230 VAC supply and is designed to survive minor interruptions to the power supply.
The amplifier’s configurable 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).

Installation
Overview - Front
| 1 | Mounting Flange | The mounting flanges are used to mount the unit in 19” equipment racks |
| 2 | Ventilation Inlets | The ventilation inlets should be kept free of obstacles and dust. Fans control the airflow based on internal temperature |
| 3 | Headphone Jack | The headphone connection can be used to listen to the different audio streams in the Amplifier. |
| 4 | Status Indicators | The status indicators are used to display the status of important parameters such as power supplies and faults |
| 5 | LCD Display | The LCD screen displays status and a graphical user interface |
| 6 | Control Knob | The control knob is used to select and execute menu items in the user interface. The knob can be rotated and pressed. |
| 7 | Integrated Handle | These integrated handles make it easy to maneuver the unit, without adding to the installation depth |
| 8 | Ventilation Inlets | The ventilation inlets should be kept free of obstacles and dust. Fans control the airflow based on internal temperature |
Overview - Back
| 1 | Ethernet Ports | Redundant Ethernet connections for audio and control data |
| 2 | Serial Console | Serial port connection for debugging and factory programming |
| 3 | Control Inputs | 6 configurable control inputs. Each input is activated by closing the loop between the two terminals |
| 4 | Fault Relay Output | A switching relay (NO, NC & COM) kept in the active position between COM and NO as long as no faults are present in the device |
| 5 | Control Outputs | Six configurable control outputs. Each is made of a switching relay (NO, NC and COM) in parallel with a 24VDC signal. The 24VDC part of the control output can source max 200mA and has overcurrent protection |
| 6 | Audio Inputs | Microphone and line-in audio inputs for microphones or external audio sources |
| 7 | Speaker Outputs | 100 and 70 volt outputs per channel. Each channel also has a low-power 8ohm output for single speakers. Each channel is equipped with inputs for connection to a hot-standby amplifier |
| 8 | Ground Connection | Ground connection for grounding of the unit. This is connected in parallel with the ground connection in the AC power inlet |
| 9 | AC Power Switch | Power switch for AC power |
| 10 | AC Power Inlet | AC power inlet for 110 to 230 VAC. The power inlet has a V-Lock mechanism for a secure connection |
Placement and Stacking
The amplifier is designed to deliver full power at ambient temperatures up to 55 °C. As long as the equipment rack is well ventilated, amplifiers can be stacked with no extra space between them. It is however recommended to add 1 HU between every group of 4 amplifiers.
Mounting
The amplifier’s mechanical construction is rigid enough to be mounted using only the four holes in the mounting flange to secure it to the rack. It is however considered good practice to mount support rails if the system is installed in a mobile environment.
