About this deal

Addition of signal interconnection cables to a system where equipment enclosures are already required to be bonded to ground can create ground loops. Proper design of such a system will satisfy both safety grounding requirements and signal integrity. For this reason, in some large professional installations such as recording studios, it is sometimes the practice to provide two completely separate ground connections to equipment bays. One is the normal safety ground that connects to exposed metalwork, the other is a technical ground for cable screens and the like.

Installing a ground loop isolator to your radio equipment may be the answer to your problem.

Keep Noise Out of Your System and Eliminate Ground Loops: How

These windings induce an identical signal in a similar winding on the other side, duplicating the input signal without an electrical connection. A similar design is used in line levelconverters which also isolate their inputs and outputs. Do ground loop noise isolators always work?because of the flowing stray currents on the ungrounded equipment. A better method of employing ground lift is to modify the cable to include an AC path between grounds, or a small capacitor.

A DIY ground Loop Isolator may be your only solution to having a clear radio reception. Sometimes you may experience static or distortion to the audio signal.Speaker cables have far stronger signals traveling along them, so they shouldn’t be as affected by RFI. But just to be safe, try to keep your AC cords isolated. In circuits producing high-frequency noise such as computer components, ferrite bead chokes are placed around cables just before the termination to the next appliance (e.g., the computer). These present a high impedance only at high frequency, so they will effectively stop radio frequency and digital noise, but will have little effect on 50/60Hz noise. Have all the necessary components and tools ready. If you have a work surface, carefully arrange each item on the table.
