The illustration shows a microphone connected to an audio interface sending sound out to powered monitors. (The computer would be connected via a firewire or USB cable, but this is not important in the context of signal path right now). Here is the all important input signal chain:
Microphone > XLR Cable > Interface
If any one of these links in the chain are of low quality or damaged then your signal is going to be low quality or damaged. If you keep this signal chain as high a quality as possible, then you will reap the benefits of having a top quality, professional sound. For example: you could have the best microphone and best interface but if you are using a frayed XLR from the 70's, your signal chain is as weak as that link. Buy the best quality you can afford for every chain in the link, especially on the input signal chain. The second key to a professional sound is simple: Your Knowledge. This is even more important than your gear or signal path. Your command and control of that gear is the most important aspect of your studio, and in the end the greatest secret to a professional sound. So go back and evaluate your signal chain and make it as strong as possible then learn all you can to use it so your recording will sound as good as possible too. Some sources for learning: 1.
