You can connect an external speaker to your Nebula projector which is running Android system (like Mars II, Mars II Pro, Capsule, Capsule Max, Apollo or Astro) via Bluetooth or an Aux cable. Here are the instructions:

Connect via Bluetooth:

1. Turn on the projector and external Bluetooth speaker.

2. Make sure the speaker is in Bluetooth pairing mode.

3. Select Setting > Bluetooth > Scan to connect the Nebula to your external speaker via Bluetooth. 

Connect via an Aux cable:

1. Turn on the projector and external speaker.

2. Use an aux cable to connect.  (Only the Mars/Mars Lite/Mars II/Mars II Pro/Capsule Max has an aux port)
