Review on 🔌 BobWire DAT1 with 12V Trigger: Supporting SONOS Connect, Echo Link, ChromeCast Audio, TV, Optical Audio Out Devices. Auto Power On for Amplifiers & Fans. Not Suitable for AV Receivers. by Marcus Hardin

Works as described. I connected it to a Bluetooth receiver with an optical output. I have a Revain Echo that connects via Bluetooth from 20 feet away. The trigger turns on the amplifier (which is powered by the Bluetooth receiver) when sound comes from the Echo, e.g. B. when Alexa answers a question or plays music. If your amp doesn't have a trigger input, check this device: https://www. .amazon.com/gp/product/B00WV7GMA2 It turns the outlet on and off depending on the presence of a trigger signal.
