ABSTRACT:
A power supply arrangement for a distributed entertainment system. The power supply arrangement comprises: first and second power supplies, which are floating in relation to each other; a first electrical connector having a distributed impedance for connecting zone apparatus to the first power supply; and a signal processor which is operative to draw power from the second power supply and to transmit electrical signals to the zone apparatus and/or receive electrical signals from the zone apparatus, and in which the zone apparatus is operative to draw current from the first power supply, thereby causing a potential drop across the distributed impedance of the first electrical connector which in turn changes a voltage of a power supply rail at the zone apparatus, characterized by a second electrical connector for connecting the power supply rail of the zone apparatus to a power supply rail of the second power supply.
