    Product description

    The KB-15x is a type approved electronic ship horn and voice hailing system for marine use that produces a powerful horn signal in excess of 120 decibels for vessels up to 20 meters (65 ft) in length.

    In addition, the KB-15W-BT model provides voice amplification for marine hailing purposes and Bluetooth™ connectivity for mobile devices.

    With the Kahlenberg Industries Mobile Application (downloadable from Google Play and I-tunes), the library of Kahlenberg Air Horn sounds can be played as well as any other music files.

    Included are a "black box" control module for mounting inside the helm station, "push to talk" microphone with mounting bracket, and a high output marine duty speaker made entirely from corrosion proof materials. Auxiliary inputs are included for connection of other audio sources such as radios or public address systems.

    The KB-15W Horn Signal is ideally controlled with the Kahlenberg M-127 rocker switch, and can also be used with any Kahlenberg Signal Timer/Control for automatic operation in restricted visibility.
