Audio Setup

Quick Start

• Make sure the AV Receiver is on. It usually is. Make sure its source is set to CD-R.
• To use the Android TV:
  • Make sure the onn Box is on: if the LED in front of it is red, then it's off. Find its remote and turn it on.
  • You can also optionally turn on the TV. Make sure it's set to HDMI 1.
• To use Bluetooth, see Connecting to Bluetooth.
• To use the media desk:
  • The mixer on the media desk should already be wired to the audio mixer.
• To use the rally bar:
  • Use the in-built speakers. The rally bar is not wired up to the AV system.

Connecting to Bluetooth

We use a "UGREEN-BT505" as the Bluetooth receiver. Its controls are as following:

• To turn it on, hold the top button. The LED light should come up. You'll also hear it saying "Powered on."
• To turn it off, hold the top button again.
• To enter pairing mode, double-tap the top button. The LED light should be flashing red and blue. You should be able to find a Bluetooth device with this name after that.

This Bluetooth receiver can connect up to 2 devices simultaneously. If you're having issues with connecting to it, you might want to make sure that no one is connected to it. If you're unable to connect, try putting it into pairing mode and then reconnecting.
