Instrument/Coassial/unbalaced Cable
Coaxial cables (also “video cables”) are signal cables that convey electrical signals: they are made differently according to the frequency of the signal being transported and the power; they can have different impedance, with the most common being 50 and 75ohm. The “instrument” cable is an audio signal cable that normally connects, for example, the a guitar to the amp. It can be shielded and is also used for effect patches. “Instrument” cables are unbalanced cables with a conductor wire and an earth wire.
