Jarhead Posted April 4, 2015 Share Posted April 4, 2015 Hi all, Having attached the aux cable and run sound through it from my phone there is EMI noise when the charger is also plugged into the phone. Any ideas on how to rid the line of this noise? Ferrite cores look to be a cheap option, but with only some success. Phil Quote Link to comment Share on other sites More sharing options...
JW1982 Posted April 4, 2015 Share Posted April 4, 2015 This problem is most likely caused by the Phone charger. I also had this problem with a portable DVD system connected to the AUX input on my previous focus MK2. I solved this problem by installing a cheap interference suppressor between the power output and the charger of the DVD player. Quote Link to comment Share on other sites More sharing options...
Jarhead Posted April 4, 2015 Author Share Posted April 4, 2015 Thanks for the information. Don't suppose you can remember the make / type of the suppressor? Have ordered some of the clip on ferrite types, but open to suggestions. Quote Link to comment Share on other sites More sharing options...
johnH Posted April 4, 2015 Share Posted April 4, 2015 Coiled wires should also help reduce this noise. Quote Link to comment Share on other sites More sharing options...
