This device likely does not detect power lines in its default setting because it is designed to primarily detect metal objects. Power lines are typically made of non-metallic materials such as aluminum or copper, which may not be easily detectable by the device in its standard setting. However, in the metal setting, the device may be more sensitive to detecting power lines due to the conductive properties of the metal components within the power lines. Therefore, the metal setting may be more effective in detecting power lines as it increases the device's sensitivity to metallic objects. **

Yes, a surround receiver is designed to automatically detect the 5.1 mode when a compatible audio signal is received.
