Automatic medium circuit has plug-in detection circuit associated with medium output that detects medium type of device in response to plug-in/activation process, connects output to suitable input

摘要

The circuit has a plug-in detection circuit (EE) associated with the medium output (A) that detects the medium type of the device in response to a plug-in/activation process and connects the medium output to the corresponding medium input (E1-E3) and an activation detection circuit (AE) that interrupts the connection in the event of deactivation or removal of the device (G).
