I've read the PD150 has significant hiss when using the Manual Audio mode. Is there any significant noise when using an external mic on the pd100a (whether it's hiss or machine noise)? Is there even a "gain control" (i.e. Manual Audio mode) on the pd100a? Also, I've read the on-board mic doesn't turn off even when an external mic is attached...this doesn't seem to make much sense, but is it true? Is the only real solution to get a XLR adapter from Beachtek or Studio 1?(posted 8360 days ago)
