Connections: Balanced vs. Unbalanced Lines

Balanced Lines: A three-conductor system where two signal wires carry equal but opposite voltages relative to a ground wire. The ground wire acts as a shield, preventing outside interference from affecting the signal. Balanced connections are preferred for long cable runs.

Diagram Description: Illustration showing a balanced connector (e.g., XLR or TRS) with three conductors labeled: Shield (Ground), Cold (Negative), and Hot (Positive).

Unbalanced Lines: A two-wire system where the shield (ground wire) also acts as a signal conductor. Unbalanced lines are common in home hi-fi systems and for connecting electronic musical instruments. They are suitable for short distances and high signal levels.

Diagram Description: Illustration showing an unbalanced connector (e.g., TS or RCA) with two conductors labeled: Shield (Ground/Signal) and Tip (Positive).
