However this did not become widespread until repeater amplifiers became available.
Balanced line cable length.
But what makes a balanced cable special is the way the gear utilizes that.
A balanced electrical signal runs along three wires.
The cable construction used for balanced telephone cables was twisted pair.
With balanced cables you don t get the same distortions so they can be much longer without any detriment to your sound quality.
Open wires on the other hand with their lower capacitance had been used for.
High levels speaker cable are rarely balanced.
That said when the cord length is under 10 feet unbalanced cables actually have a stronger signal than balanced cables.
A balanced cable by contrast has three conductors in the connector and three wires in the cable.
As a general rule this effect is only noticeable with cables beyond 20 feet in length.
As in the unbalanced cable the ground wire still surrounds the signal wires and is used as a shield against interference.
4 what levels are you transmitting.
A ground a positive leg and a negative leg.
For an unamplified telephone line a twisted pair cable could only manage a maximum distance of 30 km.
Any noise picked up along the cable run will typically be common to both legs.
Two signals wires plus a separate ground wire.
