Does instrument cable impedance matter?



Asked by: Timothy Kirby

Are instrument cables used for high-impedance or low-impedance lines? Generally, the source impedance is the determining factor in cable selection. Instrument cables are used for a wide range of sources. Many keyboard instruments, mixers, and signal processors have very low (50 to 600 ohm) source impedances.

Does cable affect impedance?





Balanced cable means: NO it cannot change anything as cable impedance is completely irrelevant.

What is the impedance of a guitar cable?

The input impedance (resistance really) of the typical guitar amp is REALLY high: usually around 1,000,000 ohms.

Are all instrument cables the same?

Are there different types of electric instrument cables? All electric instruments—guitars, basses, and keyboards—use the same basic quarter-inch jack cable to run signals from instruments, through effects units, and into amplifiers.

How do I choose an instrument cable?

The bottom line is if you do have a high-quality buffered rig so you're using buffers.

Why is cable impedance important?





Matching impedance is very important, for example, if the system is designed to be 100 Ohms, then the cable should match that impedance, otherwise error-producing reflections are created at the impedance mismatch, seen as lower return loss in bidirectional signal cables.

What does 75 ohm impedance mean?

The 75 Ohm impedance is a world-wide accepted value for all kinds of coaxial high frequency signal connections. Impedance is another word for the value of electrical resistance for alternating current: An alternating voltage applied at one cable end results into an alternating current flowing into the cable.

What is the impedance of the instrument cable?

Instrument cables are used for a wide range of sources. Many keyboard instruments, mixers, and signal processors have very low (50 to 600 ohm) source impedances. On the other hand, typical electric guitar or bass pickups are very inductive, very high impedance (20,000 ohms and above) sources.

What gauge is instrument cable?

Generally, instrument cable center conductors are in the range of 18 to 24 AWG, with strands of 32 to 36 AWG.

Can guitar cables cause noise?

According to Ken from Yorkville, there are two main reasons why a cable can cause humming or buzz: one is due to bad solder connections, which occurs from repeated usage, which ends up creating an intermittent short and thus a grounding issue.



Do Mogami cables make a difference?

Easy to install, exceptionally low noise, astounding clarity and accuracy – all with a silent background, there’s good reason why Mogami is called “The Cable of the Pros.” Paying a lot for premium cable may seem a drag, but once you have it, it’ll pay for itself over the years.

Is a thicker guitar cable better?

By having a thicker conductor, you increase the strength of that signal path. Over time, the cable bending and twisted can cause a thinner gauge to break from fatigue.

Does cable length affect tone?

It’s commonly accepted that at about 18.5 feet you can both clearly hear and easily measure the sound changes in an electric guitar’s tone—typically a loss of highs—caused by running a high-impedance signal over that cable length . And the longer the cable, the more the tone is affected in a negative way.



How long is too long for a guitar cable?

A: It’s generally not a good idea to run unbalanced cables (guitar and bass cables, for example) farther than 30 feet – we recommend keeping them under 20 feet for least signal loss and degradation.

What is the best length for a guitar cable?

10-15 foot

Typically, 10-15 foot length cables are ideal for most stages and ensure excellent tone. Anything over 20 feet might require some adjustments.

Do cables affect guitar tone?

The electrical resistance of a guitar cable is insignificantly tiny compared with the impedance of the pickups and controls, so that won’t affect your tone a great deal, but cable capacitance is another matter altogether.



Are gold plated guitar cables better?

Gold has marginally better conductivity and corrosion resistance. I’ve never had any corrosion issues using either metal. You can clean your contacts to prevent this. Some claim that gold on nickel plugs can actually cause corrosion to the nickel side, such as if you keep your gold cable plugged in at all times.

Are guitar and instrument cables the same?

Your instrument cable is low power and high impedance. It’s built to convey a weak unamplified signal from your guitar to your amp, where it’s boosted up to a useable level.
