For example, if you simply start flailing away, swapping gear and cables and everything all at once, you may never know what actually caused (or fixed) the problem. To accurately determine the correct solution to a problem you first have to find and isolate it. Diagnosing and Troubleshooting the Problem Implement assuming the transformer has sufficient bandwidth, isn't tooĬostly or bulky, and a direct DC signal path is not required for theĪpplication. The noise coupling is primarily a function of parasitic capacitanceīetween the transformer windings and can be reduced by placing a shieldīetween the windings. Interrupting ground continuity, hence breaking ground loops.īy using an isolation transformer, the ground noise voltage will nowĪppear between the transformer windings and not circuit input. Signals, allows all the desired signals to pass freely, while The most practical and usually most cost effective method for consumer audio applications is to use an isolation transformer.Īn isolation transformer is a device which, in the case of cable Mode choke, optical coupler, balanced circuitry, or frequency selective Isolate one of the ground paths with an isolation transformer, common.
