The way PROS do it is to use a balun. BAL/UNBALANCED transformer. I make my own using Jensen transformers. Just google Jensen transformers. The site will show you the models and wiring diagrams.
Many home style amps use differentially (electronic) balanced inputs. These are notorious for introducing hum/noise, especially when connected to a 2 conductor signal feed such as an RCA or 1/4 phone. The transformer eliminates that issue.
