As Rewolf has said, My first port of call would be the ribbon connectors .

Mine was cutting out and I lost complete trust in it using it Live.

My Tec put a very very weak glue on the ribbon connector and 6 months later not a single problem.

The design of the ribbon connector Is not great TBH , It's just a plastic compression clip.

Can't blame you going for another mixer after your problems, Nothing worse than it going belly up in front of a audience, I was very close on scrapping mine and like I said I already had its replacement but the M20d when working is so so great compared to the others, Getting one reliable working is the issue  :rolleyes:

Quick update, I've now found a very good local Tec who applied a very weak glue to the ribbon connectors and that seems to have fixed the dropouts , Fair enough it took 2 attempts to finally fix it but it's been 2 months of constant use and alls still good. I'm overjoyed I've got my mixer consistently performing again ( My 1608 sits in its case now waiting!)

On a different tangent I noticed Thomann have now dropped the M20d from its pages, They normally only drop what's not available to them.

Does the earth hum happen when you use the ~L6 digital Link to connect or just when using the regular XLR connections?

It's the channel cutting out problem not a earth hum problem.

Mostly the first 6 xlr inputs and the monitors losing volume and then banging back to full volume. Does it on the L6 link and the Main L & R. It's quite a well known problem.

Just really interested to see what the newer ones are like for the same problem.

Thanks

Bought mine when they where full price £1800 but got mine as a B Stock £1450.

Like you said it's a lot of money for a mixer with a inherent problem.

I did the tape fix and a warranty repair and just got it back from another out of warranty repair, I have the Touchmix but it's far behind the M20d for function and ease of use.

There is a store that does a 5 year warranty in the Uk that tempts me to get another. Just wish Yamaha would run with the concept and bring a Version 2 out with their unbeatable 7 year warranty.

I have a older M20d with the Earth problem/drop out problem, Did they ever fix or acknowledge that it existed and change it at a production level?

Reason I ask I'm still interested in buying a new one with a long warranty.

Watch the Demo's too,  For less than half price of the M20d too. Like the Stage box concept too.

Tempted by the QSC to replace my faulty M20d but jumped at this for the money-

Amazing spec and built in Digitec/Lexicon Fx, dedicated wifi connection and works with android too, also separate monitor mixes for band members.

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.

Thats great Service from Line6,  Great Firm to deal with.

I had the drop out problem on Input 1,  In the End I returned it to DV247 and they sent it back to Line6 to look at, In the report they changed a board inside.

It sounds as good as new now, Great service from DV247.

B-stock from Thomann doesn't affect your warranty. Indeed B-stock from any supplier shouldn't affect your warranty.

Thanks for the reply,  I got the mixer from DV247 so its a 12 month warranty, I did email them and they said it was no longer covered, I replied with the 1979 Sale of goods act conditions and they have offered to have it collected FOC and looked at so thats a start, Here's keeping my fingers crossed. Thanks Again.

I checked the noise gates and they are all off, I used Channel one again with a Passive mic and it did the same again swapped to channel 2 and it worked perfectly, So looks like a problem with Channel 1 perhaps a dry solder joint? .

The mixer was bought as B Stock so I don't have a warranty and only 11 XLR inputs :(  

Thanks I'll check that out, it might be on by mistake but I don't use noise gates at all.

See my thread for details of a very similar problem....

 

After several months I diagnosed the fault down to a faulty Multi Socket on that particular input as well as input 6.

Thanks for the link Its very similar to my problem, quite worrying really for £1.5 k Mixer , Thomann although quite cheap are not great on customer care IMO.

What is the other I put you switched to? Was it 2 - 6? Or was it 7-12? I am just wondering if it was in the other "group". You can put phantom power on 1-6, or 7-12.

Its No 10 now but I tried a passive mic in No 1 and it still dropped out.

I have the full Dreamstage set up has been perfect (The Bags are poor IMO but thats a different story) 

In the last two weeks at practice we only use the vocals on input one and the speakers drop out and then pop and come back in, I'm using a Shure Beta 87 Condenser with +48v selected. We have changed leads,Mics and as a last resort switched the mic to another channel and it now works. 

Which suggests the Mic 1 input is damaged/Faulty or has dirt on the pins/Connectors

Any advice? 

Thanks
