A method and system for communicating audio, video, andor control signals within a home entertainment system. The contralateral limb being radially retained independent of the sheath introducer. for 16 hours in the atmosphere, a barrier layer containing any metal selected from palladium and platinum is farmed at a junction between the copper wire and the electrode pad. The invention allows notch frequencies in the amplitude spectrum to be eliminated, and allows improvements in both the spectral flatness and the amplitude at low frequencies.
