SWAMP 5pin DMX 110 ohm Cable Roll - 100m 100m Roll - the SWAMP DMX Digital Lighting Cable Roll is ideal for stage use and installations. 110ohm rated, thick 22AWG OFC copper conductors suited to carrying DMX (DMX512) digital signals. Outer braided copper shield plus inner aluminum foil shielding. Dual Shielded This cable roll is built from 110-ohm rated, thick 22AWG OFC copper conductors suited to carrying DMX (DMX512) digital signals. An outer braided copper shield plus inner aluminum foil shielding around the conductors cores ensures signal integrity and eliminates RFI and EMI interference which can result in DMX errors. 5-pin DMX Cables Standard DMX512 protocol specifies each cable should have "two twisted pair data paths", meaning 4 conductors + 1 ground, with 5-pin connectors. Though often only a single twisted pair (2 conductors) are utilised by DMX512 equipment, so often manufacturers have opted for 3pin XLR sockets to enable the use or regular mic cables. This has downfalls, as many mic cables do not have the shielding capabilities of rejecting interference, only "braided" shield microphones are really suitable for DMX512 signals. Are regular XLR microphone cables ok to use for DMX signals? DMX signals are much more vulnerable to interference than analog audio signals. Using a mic cable can result in interference reaching the DMX signal causing a range of errors in the controllers and dimmers. A 110-ohm rated cable with either a foil or braided shield should be used (ideally both) for DMX lighting signals to reduce the possibility of interference.
