Hi John,
I did try the Line input but there was very little movement of the level meter
even on iRig maximum gain. Perhaps I missed something; I'll look again.
Re experimenting with gain, it didn't occur to me. This was probably due to
being aware that the LS-10 was 'quietest' on max gain, and this in turn another
reason I used/use the iRig to set levels. Perhaps I should experiment some
more; the only problem with this is, that I have to do it well after midnight
to get sufficiently quiet ambient noise outside. I live in a town, close to a
main trunk road, and have all the problems that our friend David is lucky not
to have!
I've not been particularly well of late, and have had problems motivating
myself to do a great deal of experimenting. But, the iRig is only one of the
possibilities I'm testing to use with my LS-1O. The two others that need
further investigation are the Avlex stereo mic, and the Nakamichi mics set.
Hopefully someday soon I'll force myself out into the rain and do some serious
work on this subject. I've just re-bought another ME66/K6 combo today to
experiment using them as a stereo pair, something I didn't try when I
previously had three! I will be using these with my Tascam HD-P2.
Cheers
Max
