I need to know whether or not this mono 1/4" jack to RCA jack adapter can make a proper unbalanced connection when used in a balanced TRS jack? What I plan to do is use my existing premium quality audio cable interconnects (with male RCA jacks at each end) to connect my home audio AVR pre-outs to a pro audio active crossover having balanced TRS input and output jacks. Will the use of these adapters make it quick and easy to make those connections without introducing audible hum or hiss and still preserve the same audio quality that I already have in my system? That way I can get by without having to make or buy new cables with a male RCA jack at one end and a mono 1/4" jack at the other. TIA.
