The KBSound In-Wall Bluetooth Audio Receiver with Two 5" Speakers and Power Supply, White (U.S.), can be wired to external speakers and paired with Bluetooth-enabled devices to provide quality sound when listening to digital audio content. This kit includes an audio receiver, two 5 loudspeakers, and a power supply. The audio receiver can fit into any DECORA light switch opening, allowing it to perfectly blend with other DECORA style light switches. The receiver features right and left speaker outputs and has a signal reach of 33 feet so you can easily pair it with your smartphone or other Bluetooth-friendly device. This will allow you to listen to all of your favorite online music streaming stations, podcasts, and other online audio content.

  • Includes a Bluetooth Audio Receiver, two 5" speakers, and power supply
  • Pairs with Bluetooth devices and connects to external speakers for streaming music, online podcasts, or other audio content
  • Fits into Decora style light switches
  • Left and right speaker outputs for connecting to external speakers
  • External audio input (3.5mm Jack) for connecting to other devices
  • Line output for extending signal to a different area/room
  • Bluetooth ID can be assigned to each module so that they can co-exist in the same installation

The KBSound In-Wall Bluetooth Audio Receiver features an external audio input (3.5mm Jack), a power connect button, an LED status light, and a Bluetooth identifier number to allow different modules to coexist in the same installation. The receiver also provides a stereo line output so you can extend the audio signal to a secondary area/room or increase the audio output level with an auxiliary amplifier (part# 13204, sold separately).

You can connect up to two 8 ohm speakers (included) or up to four 16 ohm speakers (not included) with a maximum stereo speaker output of 5W. This module also has a Max Volume Limit Switch in the back with 2 positions that will allow the installer to select what the maximum volume will be during normal operation.

Each audio receiver module has a KINGBT-XXXX identifying number associated with it. The XXXX will be the serial number that lets the user identify each individual module that co-exists within the same installation. An adhesive label with the serial number is included with each module so you can fix it to the face cover. This will allow users to choose which module to stream audio through from their smartphone or other Bluetooth friendly device.
