Unbalanced cables are a common type of audio cable used for short-distance signal transmission. They consist of two conductors: a signal wire and a ground wire. The signal wire carries the audio, while the ground wire helps complete the circuit. However, this design makes them more susceptible to noise and interference, especially over longer cable runs.
When Should You Use Unbalanced Cables?
Unbalanced audio cables work best in situations where cable length is short and interference is minimal. They are commonly used for:
Electric guitars and basses – Most instrument cables are unbalanced
Keyboard and synthesizer connections – Many consumer audio devices use unbalanced cables
Short audio connections in home studios – As long as interference isn’t a concern, they work fine
Common Types of Unbalanced Audio Cables
TS Cables (Tip-Sleeve): These are typically used for instruments like guitars and basses.
RCA Cables: Found in home audio systems and DJ equipment, these are used for stereo audio connections.
Downsides of Unbalanced Audio Cables
Prone to Noise and Interference: Without noise-canceling properties, unbalanced cables can pick up electromagnetic interference (EMI)
Limited Cable Length: Anything beyond 10-15 feet increases the chance of signal degradation
How to Reduce Noise with Unbalanced Audio Cables
If you must use unbalanced cables, here’s how to minimize interference:
Keep cables short – The shorter, the better
Avoid running near power cables – Electrical interference can introduce unwanted hum
Use high-quality shielded cables – A good shield can help reject some noise
While unbalanced audio cables have their limitations, they are still widely used for many audio applications. If you’re dealing with short distances and a relatively interference-free environment, they can be a cost-effective and simple solution for your setup.
