The Basics
How To Wrap Cables
The Best Method (In My Opinion) Is the "Jump Rope Method" Put both ends together then again and again until it is small and you can either velcro or wrap inside itself. The second method I would recommend is linked here. PLEASE DO NOT WRAP CABLES AROUND YOUR ARM.
What Are The Types Of Cables?
XLR - Commonly known as the Mic Cable. Has a circular end with three prongs (male) or three holes (female)
Instrument - Used to take the signal from an instrument to the board or an amplifier. This is for non-powered signals. Can also be referred to as 1/4" (Quarter Inch), Mono/TS Cable, and Stereo/TRS Cable.
Speaker - Used to take a signal from an amplifier to a passive (non-self powered) speaker.
