REFERENCEConnections - Balanced and UnbalancedThere are two basic types of audio system interconnections for audio signals: Balanced andUnbalanced. Your EON15 G2 can accept either type of input.Balanced LinesIn audio, a balanced line is a three-conductor system in which the two signal wires carry an equal,but opposite voltage with respect to the ground wire. The ground wire acts only as a shield anddoes not carry any audio signal current. Outside interference (such as RFI - Radio FrequencyInterference) is either shielded from the internal signal conductor, or if it gets into the cable iscancelled out by the opposite signals at the receiving end. Balanced connections are preferred forany longer cable runs.Unbalanced LinesUnbalanced cable is a two-wire system where the shield (ground wire) acts as one of the currentcarrying signal conductors. The center conductor enclosed by the shield is commonly known asthe “hot” conductor. Unbalanced audio cables do not reject noise as well as balanced lines.Unbalanced lines are typical in home hi-fi type systems and on the outputs of electronic musicalinstruments. These work well if the distance between the components is short, the signal level isrelatively high and all of the electronics used in the system are plugged into the same AC service.Unbalanced Sources to EON Powered LoudspeakersIf you need to connect your EON speakers to an unbalanced source you have two options:• Use the LINE 2 and LINE 3 connectors. These inputs are balanced but will accept unbalancedinputs without the need for any special adapters.• Use an adapter or special cable (see the section “Cables and Connectors”)17
