To my knowlege, the DSR-PD150 is the only camcorder to have the hiss (lucky me, I've got one). I do not know, however, if the PD100A has what introduces the problem in the first place, a manual gain control (my guess is it doesn't since it is an awfully pared-down unit to begin with, and might not carry so many extras). As for beachtek, don't worry, the PD100A already comes with XLR audio (one channel only, I believe) so you won't need an adapter. This was all part of Sony's grand scheme to upconvert, so to speak, the TRV900 and the VX2000 into their entry-level pro counterparts, the PD100A and PD150. Hope this helps.(posted 8044 days ago)
