The KB Sound Mando FM/DAB Radio & Bluetooth is a popular in wall Bluetooth speaker system with low profile in ceiling speakers designed for quality background radio and music streaming in your home.

It's perfect for use in kitchens, bedrooms, bathrooms, garden rooms and many more possibilities.

The stylish gloss black, white or stainless steel faceplates at the same size as a UK light switch will look at home in any room.


  • BLUETOOTH STREAMING: Wirelessly connect your smart phone, tablet or computer to the Mando unit via Bluetooth. Any music, radio station, podcast or audio book that your device can play will sound through the ceiling speakers from a range of up to 10 metres.

  • FM / DAB RADIO TUNER: Play your favourite radio station through the build in radio tuner at the touch of a button, no need to use your smart phone. With options for both FM or FM & DAB you'll be sure to find your favourite station. 

  • EASY TO USE: The Mando has been specially designed to be simple to operate with only the buttons you really need. The front plate features an on & off button, an input source select button to switch between radio & Bluetooth, volume up and down and channel up and down buttons.

  • STYLISH DESIGN: The Mando features a high gloss glass surround and faceplate. Available in black or white they look stylish and high-end in any decor. The Mando is also available in Silver which is a high quality stainless steel effect. Whatever your decor the Mando will fit right in.

  • SECURE PAIRING: Connecting to the Mando is very easy, you simply press and hold the power button for four seconds which initiates Bluetooth pairing mode allowing you to connect on your smart device. This is both easy to do and also prevents neighbours from connecting to your speaker system.
  • VOLUME LIMITER: If you're planning to install the Mando into a kids bedroom or in hospitality such as an hotel room or similar then you'll be pleased to know that you can easily adjust the amplifiers output volume to reduce the chance of annoying the neighbours.

  • STEREO / MONO SWITCH: A switch on the rear of the unit allows you to switch between stereo and mono playback mode. Most of the time you'll be using stereo, however if you want to put one speaker in the bedroom and one speaker in the en-suite then you can set it to mono mode to achieve this.


The Mando BT ceiling speaker system is surprisingly simple to install.

It sits in a standard UK back box (47mm deep) and can be fitted to either a flush mount box or a plasterboard box.

Powered from an in-line 15V transformer, much the same as a 12V downlight then connected to the ceiling speakers with the included 2 core speaker cable.

Once installed it is the same size and similar profile to a standard UK light switch meaning it's easy and discreet to fit into any room.

The Mando BT can be used to power ceiling speakers in the bathroom, but the amplifier should be mounted outside of the room.
