In testing the DR-100 MKII, I've noticed that in MONO mode, with a mic in the left XLR and no mic in the right XLR, with the limiter switch on the back set to OFF, the limiter still seems to be engaged. And it is very ugly, with overmodulation at -6 db, the wave forms hitting a brick wall. With the limiter switch set to ON, the limiter works like I would expect, the wave form can approach 0 db and it sounds much better.
In STEREO mode, the limiter is off when the switch is off, and on when the switch is on.
Maybe I should just use stereo mode as the workaround, but for recording film dialogue with a shotgun mic on a boom, I would prefer to have the two duplicate channels of audio that you get in mono mode, rather than dialogue only in the left channel and an empty right channel that you get in stereo mode. And I would like to be able to truly turn off the limiter in mono mode if I want to.
If someone else has noticed this, or could reproduce the results, maybe Tascam could fix it with a firmware update.
Any advice appreciated,
