Lundahl Problem Solvers Audio Isolation Transformer Units and Adapter Cables are specialised, high-performance in-line audio isolation transformer units and adapter cables.  They are engineered to fix persistent noise, hum, and interfacing challenges between different pieces of audio equipment. 

They completely break up ground loops—the primary cause of unwanted electrical hum, buzz, and mains noise in live sound or studio environments. They cleanly convert unbalanced consumer signals (such as those from laptops, smartphones, tablets, or CD players) into professional balanced signals (XLR or high-impedance paths) without degrading the signal. They offer a solution for all combinations of XLR, RCA, and 1/4-inch jacks. You can even use the transformers for direct wiring into your system.
