NO "Matrixing" only single(stereo) input is possible. Selectable on front panel. Dunno bout cases.
Okay got it, so those look like a couple more difference's btw. the SD units. I believe the MixPre-D can do a matrix and has a field case available.
I've still got my DigiMod UA-5 BM2p+, have considered selling it and only hanging on to it for the occasional matrix. If eventually deciding to go with a USBPre2 then the UA5 would still be necessary if ever doing an "on-the-fly matrix".
Not ruling out USBPre2, just making notes and weighing options for future plans. Haven't found a rental house with these units as yet but maybe one will turn up.
Choice is pretty much narrowed down to just the SD units, especially considering your experienced opinion that the sound quality is effectively the same as a V3.
Thanks for your feedback, it is greatly appreciated.
