Which way is correct? Yes, the good old power cord and there certainly is a right and a wrong way for the power cord to be plugged in. You must get the positive supply to the correct point on your equipment and to do this is very easy. And, all you need is a test light or test screwdriver.
Every component in your system must have the positive side of the power going the correct way so everything is working together. You would be surprised to learn that many people have a player one way and the amplifier the other way and this is just something which is overlooked. Let us start with the first item in your system – Plug the power cord into the power socket and put the screwdriver into the right-hand side and it should light up.
But, if it does not light up then simply pull out the power cord and rotate it 180 degrees and put it back in and check again and, this time, it will light up. I always think of a Christmas tree and look at the tree and say oh yes power to the bottom right of the tree but we all have our ways to remember things. You can even put a red mark with the aid of a nail varnish brush to identify.
Once you have done this put it back into your source (CD, DVD, T/T, Media player) and just listen and you will hear there are a right and a wrong way. The next step is to go to the next item in your system and do the same test to make sure it is correct. Remember the positive pin on the right then plug it in and check. After this, you can go to every item in your system and repeat the process and then sit back and listen.
If you have a power supply or conditioner fitted or an extension cord then it is essential that you check EVERY power cord in your system. Many people forget to check and wonder why it just does not as good as it should.
You would be surprised, just how much difference this can make to your system sound. And, I have helped many people to improve their sound with this very simple and inexpensive technique. I would seriously suggest, you invest in a one euro screwdriver to check out your system polarity. So, give it a try as it only takes a few minutes of your time!
