Lead/cable
Lead/cable – the wire that joins two connectors. In sound engineering it is standard to refer to the leads and cables by their termination connectors, for example an xlr to xlr cable would be referred to as either an xlr cable or a microphone (mic) lead. There are essentially three types of cable in sound engineering: 1. ‘Screened’, unbalanced cable usually used to connect between guitars and keyboards, hi-fi and non-professional devices. Normally these terminate in either jack or phono plugs. The ‘screening’ is usually a braided cable that surrounds an inner core cable. The screen is connected to earth and the core carries the signal. This screening eliminates interference and hum. 2. Screened, balanced cable normally used for microphone leads and to interconnect professional and semi-professional equipment. These normally terminate in either xlr or trs jack plugs. 3. Speaker cable used for connecting the output of amplifiers to loudspeakers or pa systems. Speaker cable must be unscreened. Using speaker cables for audio connections other than speakers will result in hum and possibly radio frequency interference.
