Almost all of my equipment is connected tru jack terminals but i have some that only have rca terminals and it becomes a problem trying to connect everything.
Most of the rca connectors that I have are on dj's specific equipment, I dont know really why, but that seems to be the standard, so this piece of kit comes very handy when I want to think outside the box and, for example, want to connect a cd player to my pedalboard so i can process the signal getting new sounds.
It feels sturdy, light weight, connects the terminals very well, secure them like a boss, it is very well made and it is very useful for many applications.
I didn't experience any signal loss and, when i measured the electrical resistance, I've got very low values so it should be fine for any studio or musician. I didn't measure the frequency response but I'm not expecting to have any problem from a device like this in my applications.
I would recommend the sssnake 1811 Adapter for any studio because for a very low price, even if you don't need it right now, it will be useful somewhere down the road.
