Bernie,

Unfortunately, I have also had some glitches, they can occur on either righ=
t or left but
never at the same time. The glitch is electronic in that is spread across t=
he full
frequency spectrum and looks very similar to those you can get on the PC wh=
en your audio
editor gets interrupted by another process or when the latency is not setup=
 correctly.

I have produced a sonograph of a couple of typical pops here:
http://www.mikeoates.org/arl/misc/ls-10_pop.jpg
The left pop is 0.02 seconds in length while the one on the right is 0.01 s=
econds.

I was thinking it may have been some electrical interference because the ba=
ttery box I am
using for my external mics is not screened. In fact I am right now this wee=
kend building
another one in a metal box in the hope that it solves the problem. Now I am=
 wondering if
it will :(

The glitch or pop sound has happened when recording inside in the warm and =
outside in
freezing conditions. It has also occurred at the two recording settings I u=
se: 44.1kHz
24bit and 96kHz 24bit. The image above is from a 96kHz recording.

I should add that it only occurs on a small number of recordings, most are =
fine.

I have also got another problem, that I can't replicate, it has happened ju=
st twice, in
that (again using the same battery box and external mics) the Left channel =
recorded at 6dB
lower. This is from the moment of starting that recording, even when I had =
just done
previous recordings that were fine and all I did was press stop, them start=
 record again.

I too am now rather concerned that there may be a fault with the machine. B=
ut as I only
ever use it with external mics, I have not been able to rule that part out =
yet.

Regards,

Mike
