You're technically supposed to use a 110 Ohm impedance cable. Belden 1800F digital audio cable like what is sold by Blue Jeans Cable has a nominal characteristic impedance of 110 Ohms, for example. It's possible the balanced analog interconnect you already have is 110 Ohms.
Aes-ebu vs. balanced cable
I need to run a cable (male to female) between my dac and a reclocking device. The dac input is labeled aes-ebu. The plugs on both devices look the same as xlr. One cable distributor said to just use a balanced interconnect, which I already have. Others have said I need need a special aes-ebu 110 cable. I don’t really understand such details. Can anyone offer advice on who is right and whether to buy an aes ebu cable? Would it do any harm to tryna balanced interconnect?

@engineears I don't think there is any pro or con associated with using a 110 Ohm impedance cable for analog balanced XLR interconnects. This Sound on Sound article Understanding Impedance has a good section on the 600 Ohm standard and why we don't care about that for consumer analog audio because we use a voltage signal instead of a power signal. |
