The T+A Power Bar mains distribution panel is designed to act as the central filter and protective device for the entire Hi-Fi system, and it very effectively prevents individual components of the system interfering with each other. It features two (red) sockets for analogue equipment, two (white) sockets for digitally controlled equipment, and two (blue) sockets for fully digital devices. These are de-coupled from each other and from the analogue sockets by separate mantle current filters.
