Expand your KB Sound Select BT speaker system to another nearby room or area and control it from the app!

Both areas can play the same music in perfect sync.

Perfect for the kitchen and dining room, or the bedroom and bathroom!

Simply play the music through your KB Sound Select BT app then tap the Slave Zone button to turn the second room on or off.


  • 5W + 5W (8 ohm)
  • Connect Up To 4 Amplifiers To One Select BT (all amplifiers will be turned on/off with the single zone switch)
  • Set zones to mono / stereo
  • Limit the volume in certain zones.

This slave zone kit requires the KB Sound Star master unit to work. It does not work on its own.

You can mix & match. i.e main zone with 5" ceiling speakers, sub zone with outdoor patio speakers etc.

Please bear in mind that the master module contains the bluetooth receiver, the slave amplifiers do not extend the signal so your playback device must be within range of the master module.
