An electrical circuit in which both the signal leads (positive and negative, active and neutral or whatever) carry equal but inverse signals produced by the source. These require three conductors: two for the signal plus a separate one for the shielding. Balanced connexions are fairly rare in consumer electronics, although they are provided in some high-end equipment. Well-designed balanced circuits provide excellent rejection of electrical interference generated in connecting wires. Balanced connexions frequently use XLR plugs and sockets.
