tochiro Posted March 9, 2015 Share Posted March 9, 2015 Hi, We are a duet and yesterday just before the gig we had a big problem - the volume of the 2 voice mics was suddenly very low in the front mix. We rehearsed a song and everything was ok. I did not change anything to the M20D and we decided to rehearse another song. This time the volume of the 2 voice mics (and only that) was very low, barely audible in the front mix whereas it was normal in our monitors. I tried to increase the input level, the output level with no results. I decided to recall an old setup memory and scene memory and that solved the issue. The problem is that we had to entirely re-adjust all the parameters, which took some time... What could have been the cause? Anybody already experienced that? Thank you. Cheers Quote Link to comment Share on other sites More sharing options...
dboomer Posted March 9, 2015 Share Posted March 9, 2015 Not enough information to guess the cause. Could be a hardware issue, could have been the mic cable or possibly you accidentally brushed the touchscreen and unknowingly changed a parameter. It is likely that it is not a hardware problem as reloading a setup corrected the problem. A note about using scenes/setups ... I frequently make copies as I go along. I start with "My Scene" and as the night progresses I save any updates as "My Scene2", "My Scene3", etc. I blow them out at the end of a gig but this way you are less likely to have to start over should something like this happen.

tochiro Posted March 9, 2015 Author Share Posted March 9, 2015 It could not be the mic cables because 2 mics each with its cable and input were involved and the problem was exactly the same for the 2 mics. I'm sure I did not touch the M20D. I agree it cannot be a hardware problem. Quote Link to comment Share on other sites More sharing options...
lawrence_Arps Posted March 11, 2015 Share Posted March 11, 2015 be prepared for this to happen a lot....and search the forum as many of us have this issue. Sure...it is possible that some of the people reporting this have faulty leads or whatever...but not the majority. Some believe its an earthing (Ground) fault ..or at least poor design of the grounding in the mixer. Many people have solved this with modifications..of course that voids warranty. My own MD20 has been at the service workshop for a couple of months now trying to fix this exact fault......rendering my whole rig unusable. I love this sytem, but none of my friends and colleagues who have purchased competing digital mixers are experiencing this type of problem. ....I just want my mixer back and working reliably....:-( Quote Link to comment Share on other sites More sharing options...
tochiro Posted March 12, 2015 Author Share Posted March 12, 2015 Yes it's worrying me because this problem might be back again any time since we don't know the cause. This is very embarrassing in front of your customer or the audience... to say the least. Quote Link to comment Share on other sites More sharing options...
timothybhewittesq Posted March 22, 2015 Share Posted March 22, 2015 Is 'trim tracking' on for the vox channels? If so, turn it off. Quote Link to comment Share on other sites More sharing options...
tochiro Posted March 23, 2015 Author Share Posted March 23, 2015 "Trim tracking" was on on the 2 relevant channels because "trim tracking" can be useful. I switched it off. Quote Link to comment Share on other sites More sharing options...
onebass Posted March 23, 2015 Share Posted March 23, 2015 Mine cut out for the first time last night since its repair for the same thing, Really not very confident in the Mixer now and have started to look for a replacement ( QSC TM16) and just run the L3T's + Subs from that.
