UPDATE
I have just found that the Nakamichi HAS damaged my LS-10!! I am no longer =
able to use my iRig with it - no response at all, but oddly my AT-8022 doe=
s work, although I'm not sure it's supplying it's usual gain. Apart from th=
e Nakamichi lead wiring, the only other thing that's different is the plug.=
The iRig (designed for iPod etc) has a TRRS plug, the AT has TRS, and the =
Nakamichi just mono. Some of you tech guys may be able to make sense of thi=
s, but it's beyond my ken.
Some part of the input stage has been damaged, and I'm already considering =
which other Olympus I'll buy.
