The function of the ‘Line In/Out’-plug is also understand – but … is it only a plastic pin which presses the inside contacts together, or an electrical connection – for example a jack plug whose 2 contacts be short-circuited ? –> I’m looking for alternative if I dont can get such original plug.It's an electrical connection within the plug - here's a blurry photo of mine: If using a standard DIN plug, connect pins 1 to 3, and 4 to 5 as you can (just) see below.
