alphatronicsSound S-40 MOBILE

The first mobile sound projector!

More than a soundbar, more than a classic Bluetooth speaker.

For us, the evolution of mobile speakers: developed for universal use in motorhomes and caravans or as a mobile speaker in your awning area.

Connect them to your TV to experience a convincing home cinema sound in your motorhome thanks to the use of 4 x 10 watt full-range stereo speakers. The harmonised audio software means that you can enjoy top-class sound quality on TV and music playback. We placed particular emphasis on optimising the sound of voice reproduction: especially when used as a soundbar under the TV, this is an important criterion for seamless TV viewing pleasure.

The alphatronicsSound S-40 offers extensive streaming options thanks to the latest Bluetooth 5.0 standard. Choose your favourite music from your music library. Transmit it via Bluetooth to the mobile sound projector. The HDMI ARC connection allows you to connect the sound projector to your TV.


Outstanding sound quality thanks to HDMI ARC

The HDMI ARC connection allows you to enjoy the full range of Dolby Digital. Compared to conventional audio transmission via jack/AUX, this transmission standard offers a much broader and more finely tuned frequency spectrum. For it to work, however, you need a correspondingly high quality HDMI source on the other side, such as that from your alphatronics TV.

Thanks to the sophisticated mounting system, the S-40 Mobile can be rapidly disconnected from your TV and repositioned, for example in the awning area. The corresponding TV mounting bracket is included as standard. The integrated rechargeable battery enables sound playback for up to 12 hours. The practical remote control enables you to control the most important features at the touch of a button.

The alphatronicsSound S-40 MOBILE sound projector is available in two versions.

alphatronicsSound S-40 Mobile and alphatronicsSound S-40 Mobile DAB+
