If you want to record Lossless via Line- In you have to try it out with the C24 at a shop first: The reference manual doens´t say clearly if the recording via line in is limited only to Mp3 192 Kbits
(like on it´s precedessor the Pocketrak CX). And the Line in is not adjustable.
There is also a pocketrak W24 availiable (same chassis as pocketrak CX, also very compact) - but there the ref. manual also says nothing about recording via Line - In is limited to MP3 or not.
What is great if you run that Pocketraks with Eneloop´s they really last very long!
the last gig i have recorded with pocketrak CX i used the internal mic. - sense= 1, stereo setting = wide. but i was also lucky i have catched a good recording spot at the stereo center (Gagarin205 - Athens)
