![]() ![]() What helps with that is this, knowing how your sound system normally sounds and one good known working mic, and how that sounds. The last one is a tough one and very objectionable in many cases. Did I say Isolate? Be it a buzz, a hum, or no audio at all, it will take some form of Isolation to find it. You must Isolate, Isolate, Isolate in order to find the problem. In trouble shooting, isolation is key in finding where a problem is or where it is not. Always keep your cables organized for trouble shooting later if needed. At times it is better to check as you go along. Once your system is set up all the way, there can be lots cables going to lots of destinations. Example, looking for signal lights on a mixer before turning on amps. When using isolation techniques, you can make sure the signal path is hooked up and working before going to far with the set up. This is mainly used in trouble shooting, however when setting up a system, this can be very useful as well. Unless there is a system tech for the sound system, this can be dangerous. Far to often I have come across band members in charge of the sound system, or even sound guy’s / gals, that are not certain of the signal flow in regards to the system they are working with. You need to know the main components in YOUR sound system and how the signal flows from beginning to end. This is a very basic example of “Signal flow”. The following example will be a simple analog sound system.įirst, a sound source hits the microphone or Direct Box, it comes down a mic cable, it then goes into a stage snake, then into a mixing board, then into an Equalizer for the main system, then into processors for the main system, then to amplifiers, then to speakers. Let’s take a very simple sound system with a few components in the path and put them in order from beginning to end. This can be very complicated or some what simple depending on the sound system. ![]() There are many components and paths the “Signal ” goes through along the way. box, and comes out at another end, into the speaker. The sound starts at one end of the sound system, the microphone or D.I. ![]() This will be general and brief in many ways, as in I will not go into how a microphone, nor a speaker, nor other components work inside them selves. If you are setting up a sound system, or trouble shooting the system, you need to use both in either case or will at some time. The reason I am putting Signal flow and Isolation into this one blog, is because they relate to one another very closely. This months sound Blog is about Signal Flow and Isolation of sound. Here comes thanksgiving !!!! I hope your Turkeys are in a row, or at least one is. ![]()
