Jon...moe.down is next week.  I'll give it a good workout and post some recordings when I get back.

so far I have NOT found a way to disable L/R Mix channel

for doing only 2 channels Digital In...

Semi good news Darby...it turns out that you can disable any track you want to from the app.  The apps mixer screen shows all of the tracks in a red box to the left of the sliders.  If you tap the red box, it changes so that it's not red anymore.  The only tracks that have the red box lit are recorded to the poly wave file.  The display on the unit will then also change the channels that are disabled so that they are no longer highlighted in red.   

Why this can't be done from the menu is a mystery.  Hopefully that's another firmware update item for them to consider, but at least we're not stuck recording all six tracks to the poly wave.

Interesting note that the poly wave file is not limited in size.  In other words, if you record for say six hours like I did when I was doing a run time test, the recording is one huge 6 hour poly wave file.  It's not broken up into 2gb or 4gb increments, like every other recorder I've ever owned.

What I am interested in is the "handoff" between the ADCs.  I saw a video where someone showed some asymetrical wave files when the handoff between the two is involved.  You able to check this? 

Yep...no glitches for me during the battery run time test.

As reported earlier, I ran two battery tests.  The first one had the automix function on and MAN is that ever funky.  Totally useless for anything that we do, that's for sure.  The waveform was VERY wonky with it engaged.  The second run-time test had automix off.

As previously mentioned, I think in that video there's a really good chance that he was seeing the automix handing off between the channels.  Automix causes one channel to kick in and simultaneously mutes the other channel.  Then when a louder sound occurs in the other channel, it'll instantaneously peak out and the other channel is muted.  Since I was recording background noise at home, both channels had about the same sound pressure hitting them, but even so, the level would peak out on the left channel and the right would go down to zero, and the next moment the right channel would peak and the left channel would drop to zero. 

Anyway, the second test I did had the automix feature disabled.  I checked out the waveform this morning and didn't notice anything unusual from zooming in on the waveform.  I did a spot check in a number of locations along the timeline of the recording, though with the file being almost 7 hours long, I didn't zoom in on 7 hours worth of waveform.

can anyone confirm that, while using the aes inputs, the recorder writes 4 channels of bit perfect 24/96 PCM data?

Teddy said PR-4 gain is engaged during recording. so not bit perfect

he runs it at 0 on the deck

That doesn't mean it isn't bit perfect. With 32bit containers gain is just a number recorded in the file.

Testing this is simple:

take a 24/96 .wav file> aes output> record to diety> flip polarity of either the original or the new diety file> load both files into DAW w/  -3db gain> Play.

If there is complete silence, the files are the same.
