    Operating principle

    The speaker is installed into a compatible UT16 / ultra-thin type track and powered from a low-voltage DC 24-48V system. One device is set as the Host – a phone, tablet or another audio source connects to it via Bluetooth.

    Additional speakers are set as Sub Unit and automatically connect to the main Host device. This allows a wireless multi-speaker background music system to be created, where the audio signal between devices is transmitted without separate audio cables.

    What does the Host + Sub Unit system mean?
    Host is the main speaker that receives the Bluetooth signal from a phone or another device. Sub Unit is an additional speaker that synchronizes with the Host device and reproduces the same audio. The mode is selected using a DIP switch on the rear side of the device. The DIP switch must only be changed when the device is not connected to power.

    Where is it used?

    • Modern living rooms – when lighting and background audio are integrated into one ultra-thin system.
    • Kitchens and dining areas – for discreet music playback without separate speakers.
    • Cafés – for a minimalist background music solution in customer areas.
    • Hotel rooms – for aesthetic integration of audio and lighting.
    • Offices – for lounge areas, waiting rooms and representative spaces.

    Practical usage example

    For example, an ultra-thin track system with LED luminaires is installed in a modern apartment. One Bluetooth speaker, set as Host, is inserted into the same system, while additional Sub Unit speakers are placed in other areas of the room.

    A phone connects to the Host device via Bluetooth, and music is automatically transmitted to the additional speakers. This integrates lighting and background audio into one aesthetic system without separate ceiling speakers or visible audio cables.

    Use according to need

    For a home user: suitable for a living room, kitchen or bedroom when integrated sound without separate speakers is desired.

    For an interior designer: allows lighting and sound to be combined in one minimalist ultra-thin system.

    For a café or hotel owner: helps install background music while maintaining a clean and modern interior appearance.

    For an installer: it is important to check track system compatibility, power supply voltage and Host / Sub Unit layout before installation.

    Installation and usage notes

    Before installation, it is necessary to check whether the track system used is compatible with the UT16 / UT6 ultra-thin standard and whether the power supply voltage meets the DC 24-48V requirement. It is also important to plan the placement of Host and Sub Unit devices according to actual room conditions.

    • Switch the DIP switch only when the device is not connected to power.
    • Set one device as Host and additional devices as Sub Unit.
    • Check DC 24-48V power supply compatibility.
    • Do not install into incompatible tracks.
    • Do not set too large a distance between Host and Sub Unit, especially if there are obstacles between them.
    • Use indoors unless a clear IP protection rating is specified.
    • Before installation, check the track load capacity and the condition of the contacts.
    • Installation is recommended to be entrusted to a qualified specialist.
