A plurality of outlets has at least a first outlet coupled to an IR target for providing a first local comparatively low-frequency electrical IR signal in response to an IR signal received by the IR target. At least a second outlet is coupled to an IR emitter. A distribution module is coupled to each outlet by respective first and second cables, wherein each of the first and second cables is sufficient to carry both comparatively high-frequency signals and comparatively low-frequency electrical IR signals between a respective outlet and the distribution module. The distribution module combines all local electrical IR signals received from said outlets via said respective first cables into a combined electrical IR signal and transmits the combined electrical IR signal to the IR emitter via said second cable.
