    摘要: A multimedia wall outlet (400) arranged to receive radio-frequency (RF) signals via a coaxial cable (408,100), the radio-frequency (RF) signals comprising multimedia signal components on their own frequency ranges. The wall outlet (400) comprises separating means (106) for separating said multimedia signal components to their own frequency ranges and a pi tubular filter (104,410) element arranged to provide a galvanic isolation between a ground of a shield of the coaxial cable (100,408) and a ground of the wall outlet, wherein said RF signals are conducted from the coaxial cable through said pi tubular filter element (104,410) to said separating means (106).
