Balanced Line Cable Length

A balanced cable by contrast has three conductors in the connector and three wires in the cable.

Balanced line cable length.

With balanced cables you don t get the same distortions so they can be much longer without any detriment to your sound quality. That said when the cord length is under 10 feet unbalanced cables actually have a stronger signal than balanced cables. But what makes a balanced cable special is the way the gear utilizes that. The cable construction used for balanced telephone cables was twisted pair.

Two signals wires plus a separate ground wire. Open wires on the other hand with their lower capacitance had been used for. As a general rule this effect is only noticeable with cables beyond 20 feet in length. For an unamplified telephone line a twisted pair cable could only manage a maximum distance of 30 km.

High levels speaker cable are rarely balanced. A balanced electrical signal runs along three wires. 4 what levels are you transmitting. Both legs carry the same signal but in opposite polarity to each other.

Very low levels mic phono are much more susceptible to interference than line levels. A ground a positive leg and a negative leg. Any noise picked up along the cable run will typically be common to both legs. However this did not become widespread until repeater amplifiers became available.
