Well it uses AAs not AAAs, which made no sense for runtime. And the specs listing on the Zoom site don't clearly state whether it does 24/96 for four tracks or not. For SD card timing purposes, they only give the example of 4 tracks at 24/48.
You can plug a line-in feed or PIP mic into the 1/8" stereo input near the internal mics and do genuine 4 track, I think.
I was hoping, too, for F8 grade preamps and A/D, love that machine. I did see someone last night using an H6 for an official recording of a chamber music recital, maybe those pres are okay.
If Zoom answers me that 24/96 X 4 is possible, I may bite on this.
