The Rolls BT287 is a Bluetooth interface that will supply stereo or mono audio to a sound system. It also features a 400 watt contact closure relay for activation of the connected system.
For example, if you have a sound system such as an old juke box and want to add Bluetooth capability to it. The BT287 will supply audio to the juke box as well as provide a contact closure relay to turn the juke box on, control the cabinet lights, the amplifier, and the audio level remotely.
When audio is sent to the BT287, the juke box will turn on automatically and start playing audio. When Bluetooth audio is not present, the juke box will be powered off by the BT287. This way, a homeowner or shop owner could have a piece of equipment (juke box) remotely controlled via laptop, phone, tablet or another digital Bluetooth device with the BT287.
