Ran my M-10 this weekend for the first time. I've had it for months, but was scared to death to break in a new machine, but I bit the bullet and gave it a test run with Robben Ford.
I ran Schoeps MK4 with an NBox on Line In. The show was very loud and the best sound was at "6" although a second show was recorded at "5" and I felt more comfortable with that.
I had much trouble getting the Micro SD card to be recognized, but after about 30 minutes of fooling with it, its in place. What is odd is that the screen does not seem to reflect the increased recording time although Cross-Disk recording is enabled.
The clock was particularly agravating and I just gave up. Its a recorder, not a watch, as another poster suggested.
I taped the 90 degree 3.5 plug to the deck, as well as taping the volume down as well, and stuck the whole mess into a pocket.
The recording turned out perfect, as good as my old Edirol 09, so I am happy. It is half the size, so that is good as well.
When locked, I wish I could see the settings, but one has to unlock to see the VU meter, which is not a big deal. but inconvenient.
Not sure I really understand the difference between Mike In and Line In, but Mike In was easily twice as loud, the same source for the same result would be a "3" for Mike In and a "6" for Line In. I tend to be able to guess the proper setting on the Ediorl quite accurately, so I'll probably stick to Line In at "5" to be safe.
When plugged in to AC power, the display does not indicate that it is indeed plugged in.
More to come as I gain more confidence in the deck.
