Abstract (en)

[origin: EP0677978A2] The appts is provided for transmitting signals from an amplifier to a loudspeaker. It has at least one length of cable (11, 11`). The cable includes several outward leads (12, 12`) for outward transmission of electric signals, and several return leads (13, 13`) for return transmission of the signals. The outward leads (12, 12`) are electrically connected to each other at their ends. The return leads (13, 13`) are also electrically connected together at their ends. The outward and return leads (12, 12`, 13, 13`) are enclosed in a common ferrite cladding (2) so as to compensate any stray fields due to the close magnetic coupling of the leads. <IMAGE>
