    Perreaux products used with equipment manufactured by other manufacturers may cause an earth loop situation, but Perreaux products used with other Perreaux products will not cause an earth loop situation provided the following precautions are observed: The entire hi-fi system must be connected to the same mains/line power outlet.
  • Page 27 When a piece of equipment is supplied with a three pin mains/line supply lead all three pins must be connected in the correct fashion - see your dealer if in doubt. Check all interconnecting signal leads for good connections, both internal connections and firm contact with the sockets.
