In addition to its sound signalling capabilities, the Kahlenberg KB-30A also provides voice amplification and “talkback” function for communication between helm station and crew on deck. Multiple horns can be controlled from a single station for hailing/talkback and/or horn signal and auxiliary audio input is also available.
The KB-30A System comprises the horn/driver unit with integrated heater unit, and the CM-14 under console control/microphone unit.
The KB-30A can also be used in combination with the M-512 Signal Controller (as pictured), or any Kahlenberg Signal Controller for automated signalling functions.
