Deliver Wireless Audio Through Your KBSOUND STAR System

The EISsound KBSOUND STAR Space Bluetooth Amplifier streams wireless audio from Bluetooth or FM radio audio sources directly to your sound systems. This master audio transmitter module can act as either a master or add-on station to build or expand upon existing KBSOUND STAR systems. Each Amplifier supports a single pair of speakers on its own, sold separately. Up to four extra Auxiliary Amplifiers (13204) can be connected to the Space Bluetooth Amplifier using wired line output connections.

  • Bluetooth transmitter enables streaming of FM or Bluetooth connected audio
  • Up to four additional Amplifiers may be added into a single KBSOUND STAR system
  • Choose where you want your audio played: from select auxiliary speakers or the entire system
  • Control your KBSOUND STAR system using the KBSOUND App or Remote Control accessory
  • Bluetooth receiver range up to 30 feet line of sight

The Space Bluetooth Amplifier can pair with an unlimited number of audio streaming sources via Bluetooth, but only a single source may be connected at a time. The Amplifier is controlled by either the KBSOUND App or Remote Control Accessory (52402). Using the app or remote control, you can select where you want to play your audio, either across the entire system, only from the master module, or from select audio zones. This is done by pressing the power button icons within the app or on the remote control.

The Space Bluetooth Amplifier is designed to mount onto the ceiling, preferably behind or near connected speakers. The amplifier uses wired line output connections to deliver power and audio connected Auxiliary Amplifiers or just audio to connected speakers. When a Bluetooth connection is made for the first time, the Space Bluetooth Amplifier's ID and password will need to be inputted. Afterwards, the Bluetooth streaming device will only need to pair with the Amplifier.
