Comments about PSC A600 In-Line Transformer Barrel Adapter (600 Ohms):
When you need to isolate 2 mic or line level audio signals, this transformer is a good choice. Compact and extremely rugged, I carry at least 2 in my kit at all times. 2 great uses are to eliminate ground-loop hum and remove phantom power from a mic input.
Bottom Line Yes, I would recommend this to a friend
