Electronics in audio

What’s an electronics page doing in a music website, well very easy answer, without electronics we would not have modern music, so as you will appreciate the two are totally linked together

How do we hear an electric guitar. Normally we patch a phono cable from the guitar to the highz input of an amplifier to hear it?. So what does an amplifier consist of.

The electronics to boost a very tiny signal of Millivolts from the guitar, up to something big enough to drive an amplifier, and finally a loud speaker, which is powered by 240 volts AC, now that really shows you I am Australian. but now you get my drift, just how important Electronics is in music.

I will not go into the subject deeply, as that area alone is massive, but I will talk basic electronics as in cables and plugs at this point, and give you links to a course you can do on basic electronics practical and theory.

Now please understand, I am not saying you need to know the circuitry of an electronic keyboard, that’s likely impossible, but just an understanding of basic electronics, even to know the difference in the plugs, what job are they intended for, as you don’t mix them around.

Learning to play a piano

There are two different type of piano I refer too, the acoustic one, which has the strings in it on a massive metal board, which are struck by the hammer, or the electronic keyboard type, which fits into a smaller space, and delivers it sound via a speaker, and is computerized.

Here is the acoustic type which we are all familiar with.

Acoustic Piano

The acoustic piano has weighted keys, and a mechanism which moves a hammer and strikes the string. the strings which are wire, similar to a guitar, are tension-ed over a metal frame, and resonate, when the hammer strikes the string.

These types of piano’s are usually miked to get the sound out to a bigger audience.

Then we have the electronic variety, they can be weighted keys, for the feel, as they are electronic, and produce their sounds via various methods, including synthesizer, or actual memory banks which have the recorded sounds on chips

You will hear their sound via a built in speaker, or patch cable, to an external amplifier, or through a mixer.
