Is coaxial balanced or unbalanced?

The coaxial cable is an example of an unbalanced guided medium in which the center signal conductor is protected by an outer layer shield connected to ground.

What is special about coaxial cable?

Coaxial cables have concentric layers of electrical conductors and insulating material. This construction ensures signals are enclosed within the cable and prevents electrical noise from interfering with the signal.

What is an unbalanced wire?

Unbalanced Cables and Signals An unbalanced cable consists of two connectors with two conductors each, connected by two wires inside the cable—a signal wire and a ground wire. Unbalanced wiring uses just two conductors and is susceptible to picking up noise.

What is the difference between a balanced and unbalanced antenna?

Antennas can be balanced or unbalanced. A balanced antenna is symmetrical about the feed point (e.g. a dipole) whereas an unbalanced antenna is not systematical about the feed point (e.g. a Windom). In the real world all antennas are unbalanced to some degree.

How does a balanced line work?

A balanced line allows a differential receiver to reduce the noise on a connection by rejecting common-mode interference. The lines have the same impedance to ground, so the interfering fields or currents induce the same voltage in both wires.

Why are balanced cables so expensive?

XLR cables are used for long cable runs because they can interact with the interface, preamp, or mixer that the signal runs into, and flip one of the signals, putting the two back into polarity with each other. This explains why balanced XLRs are generally much more expensive than other cables.

Can you use a balanced cable in an unbalanced input?

Even if you plug a balanced cable into an unbalanced output jack, the signal will be unbalanced (see the downsides of unbalanced above). In many cases, interconnecting a balanced output to an unbalanced input will work just fine – your signal will be unbalanced.
