The Nitro Max Kit cannot be used with Bluetooth headphones or stream audio to a Bluetooth speaker.  The module will only be able to receive Bluetooth audio from your smartphone, tablet, computer, etc.  

To connect your device via Bluetooth:

  1. Press and release the Power button to power on the Nitro Max drum module. When no Bluetooth device is connected, the Bluetooth button LED will be off. 
  2. Press the Bluetooth button to enter pairing mode. The Bluetooth button LED will flash. 
  3. Navigate to your device’s Bluetooth settings and select Alesis Nitro Max. Once your device has been paired, the Bluetooth button LED will be fully lit.
    Note: If the Bluetooth button is pressed again, pairing mode will be canceled, and the LED will return to the previous state (paired with the previous device or no device).
