The LS-10 seems to have bass roll-off when recording via the mic input as a=
default.
Leonard Lombardo of Sonic Studios mentions this in his review from 2008:
http://www.sonicstudios.com/ls10revw.htm
I've noticed the difference between it and the Edirol R09-HR (also, the LS-=
10 has very low line-in sensitivity) and prefer to use the Edirol, even tho=
ugh its build quality is nowhere near as good.

normally run the gain and likely into the range where the 722 gain display=
seems less accurate. I used the 722's internal M-S decoder with M-S set to=

control. The LS-10 mic sense was set to "HIGH" and low cut was set to "OFF=
