467:. DJs sometimes have to use equipment with multiple cable types, which can create connection difficulties; for example, the DJ's record players and DJ mixers all use RCA connectors, but if they use a drum machine or a bass synthesizer, it may have a 1/4 inch mono connector. To resolve this problem, DJs can either use adapters or special cables (e.g., RCA to 1/4 inch mono). Heavier-gauge cables are used for carrying amplified signals from

would have to run 20 or 30 individual microphone and instrument cables from the stage to the mixing booth. The cables could get tangled or mixed up, and it would be hard to know, when faced with 20 connectors at the end of the cable run, which cable was associated with which microphone or instrument. The patch panel is numbered, so that the engineer can note which microphone or instrument is plugged into each numbered connection.

The term "patch" came from early use in telephony and radio studios, where extra equipment kept on standby could be temporarily substituted for failed devices. This reconnection was done via patch cords and patch panels, like the jack fields of cord-type telephone switchboards. Furthermore, patching

A patch cord cable differs from a standard structured cabling in that a patch cable is stranded for flexibility, whereas a standard cable is solid copper. Because the patch cord is stranded copper construction the
