I encountered a PROBLEM with my R-44 a few days ago when I recorded 4 tracks (44/24, 4xmono with 2x phantom, run with external power). 8 and a half minutes into the recording you can hear clicks/glitches or something like that. There was no clipping, and the sounds are not recorded, they're digital. Weird thing is, they're only on the first two tracks (the ones with phantom power switched on), for a duration of about ten seconds.
Now of course I am puzzled about the source of this. Either this has to do with the R-44 (worst case), or my SD card (Kingston class 6, 8gig), or (maybe more likely) the somewhat dodgy electricity in the space - maybe someone in the next room switched some electric device on and off? The last assumption would imply that in conditions like these you should only record with battery power!?
Any ideas, hobby electricians maybe?
If someone's interested, here's the part of the recording with the glitches (mixdown of the two phantom tracks):
