I have an unusual and annoying problem with the M20d, two things going wrong, the first happens nearly every night..
Set all up, go to sound check, the guitar (Acoustic Takamine with Line6 XD-v75 wireless system) turns on and nothing or very little sound signal coming thru for 10-15 seconds then "whompf" up to the volume it should be, occasional dropouts thru the night (on mixer not wireless). Guitar and wirless both been checked many times for faults, nothing found to be wrong with either.
Next problem happened once and totally confused me..
Same guitar and wireless setup going into XLR channel on M20d, no sound, wireless working fine, channel getting signal, fader lights on M20d going up and down showing signal, main mix strip going up and down showing signal, nothing coming out of speakers! all other channels working fine, sound coming out FOH.
I moved the guitar to another XLR channel, same problem, used another wireless pack and receiver, same problem, put the guitar on a wire to the M20d, same problem, all gates, comps, FX 's etc. turned off and guitar gives none of these problems thru any other mixer..
Does the M20d just not like Takamine acoustic guitars? Any suggestions would be great as the guitarist whines at me every night and it's driving me crazy!
Thanks
