I have this surround sound system at home that is very old and have these strange sound input sockets that I have never seen before. Does anyone know what kind of input socket this is?
They appear to be the 220V inputs (source feeds - Fuente alimentación) for each device; (L and R) as each input looks like it has two connection points. It has a custom connector that I cannot identify. If you can read spanish the manual more information is here: www.kroser-electronica.com/descargas/catalogo2007.pdf
