hi
I have 8 channels audio interface and all channels are constantly used. guitar is in one channel and I never disconnect it or switch it to another, same with keyboard and bass etc not from the interface end, not from the instrument end. but two wires is connected to the interface with female end to use it as extension cable for different instruments and this end is open when the instrument is not connected. it makes a noise and also as I know is not recommended keep wire with open end in the input and every time I have to disconnect it from the interface what is very inconvenient. I tried use TRS both mono/stereo adaptor just as a cap, to a certain extent it removes the noise but not completely like if you hold the end with hand what makes grounding. so I'm looking for some cap for this jack extension cable female ends if something exists specifically for this, but if not maybe I can do it myself ?
