66d35 Posted March 15, 2016 Share Posted March 15, 2016 Symptoms: No input levels register on mic pres, with either dynamic or condenser mics Loud crackling noise (sounds like something frying) as system (V1.20) launches Crackling noise appears on both headphone and main outs Have done a system reset and firmware reload. No change. Looks like a board failure.... :( :( Quote Link to comment Share on other sites More sharing options...
66d35 Posted March 15, 2016 Author Share Posted March 15, 2016 Well.... this is odd... after powering down and letting it stand for 10 minutes, all returned to normal. For now, at least... shall test and monitor carefully! Quote Link to comment Share on other sites More sharing options...
66d35 Posted March 16, 2016 Author Share Posted March 16, 2016 For anyone else who experiences these symptoms. We appear to have traced the cause to a bad joint inside a molded IEC power supply plug. This was 'arcing' slightly and obviously causing major line interference and a drop in voltage. Not obvious, but changing the cable and taking the old one apart revealed the damage. Just for reference. Quote Link to comment Share on other sites More sharing options...
