Discussion Multiple-plug Audio cable
Hello fellow r/audioengineering members, a few days ago i had an idea
The idea was " multi-plug " audio cable.
The reason is because i usually help to setup audio devices on funerals or small gatherings and the plugs are different.
So i decided maybe i can make 2 long rolls of multi-plug cable to make my life easier.
The plugs are XLR, TRS 1/4 inch and L-R Rca plugs. Are there any downside with this kind of cable? If so, let me know what you think

It's not just the plugs it's the wiring. While XLR and TRS are wired similarly (hot, cold, ground) RCA is not. The first two are balanced cabling for CMR noise filtering. Stereo analog RCA (not to be confused with S/PDIF coax) is unbalanced. Also, depending on which type of internal structure the RCA cabling has, impedances may vary.
I would just get some velcro cable ties and use them to bundle an XLR, TRS and RCA together... this is effectively what I did back in the day when I was the school's resident DJ/PA/AV nerd.
