Connecting a Loudspeaker to a Cortex™ Hub

With the release of Cortex Software 1.7, users can now use a connected 30W 4ohm Loudspeaker for Hailer and Fog or Horn Signaling.  

Loudspeaker Mode can be operated from a Cortex Handset (H1 Tethered or H1P Portable) or the Cortex Onboard™ App. Communicating with crew on board or other vessels is now even easier.


Users can also use the Cortex Hub to access the horn safety features over the loudspeaker. These loud audible signals are pre-programmed on the Cortex and emitted over the loudspeaker for maneuvering signals, danger or warning signals, fog signals, overtaking maneuvers in narrow channels, and for distress signals. 

These features have expanded the many useful features on the Cortex system, and have made this system an even more powerful safety tool. 


To connect the loudspeaker to the Cortex Hub

Using the included 4-pin Audio Cable you can connect a 30W loudspeaker to Cortex. This same cable is also used for the external audio speaker output.

Cortex Connection

Wiring a Loudspeaker

Plug the 4-pin Audio Cable into the Audio Port.

Speaker Connection

The 4-pin Audio Cable has 4 color-coded wires:

  • Orange - Audio Speaker Positive (+)

  • Black - Audio Speaker Negative (-)

  • Red - Loudspeaker Positive (+)

  • Brown - Loudspeaker Negative (-)

Using the Red (+) and Brown (-) wires, make a suitable connection to the installed loudspeaker.

Note: The loudspeaker can output up to a maximum of 30W. A connected loudspeaker should be capable of handling up to 30W to avoid causing potential damage.


Setting Loudspeaker Volume

Loudspeaker volume will default to Mute. To set the desired volume, use a Cortex Handset of the Cortex Onboard App.


Setting Loudspeaker Tone

Set the pitch the horn will use between 200-500Hz from the Loudspeaker settings.
