Who should turn it on or if no signal is received it will turn itself off, if it receives a new signal it will turn itself on? Thanks in advance for the answer !!!" This device does not turn off automatically. In case of signal loss, the device enters a connecting mode where known devices can connect. Two devices can be connected at the same time. Another note about this device, the optical audio input does not work with all devices. I have a Samsung TV whose optical sound is not being transmitted. It is not the TV with another brand, this works fine. See More
