Balanced Vs Unbalanced Rca Cable

A balanced electrical signal runs along three wires.

Balanced vs unbalanced rca cable.

Two signals wires plus a separate ground wire. Any noise picked up along the cable run will typically be common to both legs. Both legs carry the same signal but in opposite polarity to each other. The added safety of the balanced cable comes at a cost and even after you make the purchase you still need to pair your cables with.

Unbalanced cables aren t good for doing long cable runs for this reason in fact you should be using balanced ones if the cable needs to be more than 10 15 meters long. The 1st conduction is the audio signal itself and the 2nd is a ground and often a shielding. Balanced cables and signals. Unbalanced cables depending on their quality might be anywhere from 30 60 of the cost of their balanced counterparts.

An unbalanced single ended interface uses only two conductors to carry the signal from one device to another one conductor carries the signal and the other is the grounded return. A ground a positive leg and a negative leg. Unbalanced line level connections are usually implemented with rca jacks for audio while balanced line level connections typically utilize dual 3 pin xlr jacks for both the input and output. I demonstrate exactly whats going on under the hood of bal.

Balanced xlr vs unbalanced rca i suggest that you simply make a couple of cables connecting a 1 4 inch trs tip ring sleeve balanced plug to a male single ended rca plug making sure to connect the hot signal on the balanced 1 4 connector the tip to the hot pin on the rca plug. This is especially true if it needs to be used in an environment where there s a lot of lights and other stuff that could cause interference. In consumer audio systems this usually consists of a cable with a center conductor and a shield terminated in an rca phono plug. As in the unbalanced cable the ground wire still surrounds the signal wires and is used as a shield against interference.

A balanced cable by contrast has three conductors in the connector and three wires in the cable. A balanced audio cable has a ground wire but it also carries two copies of the same incoming audio signal sometimes referred to as a hot positive and cold negative signal. The main difference comparing balanced vs unbalanced cables is a balanced cable has 1 additional conductor. The diagram above shows how the cable works.

A typical unbalanced cable like a 1 4 instrument cable has 2 conductors. This video will explain the difference between recording audio with balanced vs unbalanced cables. In truth the main advantage an unbalanced cable has over a balanced cable is the cost.
