I also got a chance to try out my new Deity PR-2 last weekend.
I recorded a couple of shows and the unit seemed to perform flawlessly. I'm also running Church Audio CA-11 mics straight into the PR-2. I confirmed that the PIP is 5V (and not adjustable as far as I can tell...)
The unit is very small. I brought it into the United Center in Chicago in a small bag with some other stuff and no issues.
Here are some tidbits:
1. As noted earlier, the battery compartment door is very tight. So tight that I'm afraid to completely close it - I leave enough of a gap that I can get my fingernails in to wrench it back open. The batteries are also extremely tight and take a lot of force to get them in. I've tried NiMH and standard alkalines. Both very tight. Have not tried the supplied Deity lithium batteries...
2. The unit automatically splits long recordings into separate files. The split point is just past 4 hours (4:08:32 in my test). The file size was 4,194,001 kb. The rejoined files sounded smooth across the split point.
3. If you pop a battery out during a recording, the unit saves the file and then shuts off. I shoved the battery back in after 5 seconds, but the unit was already off.
4. The Deity runs its date clock even without batteries for at least a few days. I doubt it would keep the date function current forever, but you certainly won't lose the date if you swap batteries. The unit saves files in folders for each date as "PR-2 -001"; "-002", etc. In each folder, the file name sequence starts over. You've got to be a bit careful when you transfer several "PR-2 -001" files recorded on several different dates.
5. The gain controls for L and R do not link. If you're recording and need to change gain, the changes will occur on each channel, independently, as you spin the gain dial.
6. The recordings I made sound fine, and I was nowhere near clipping the analog inputs of the Deity. But, I have no idea where the CA-11 mics will start to clip with 5 volts. I've read that they have less than 0.6% THD at 114 dB at 1000 Hz with 9 volts. Not sure how to get to those volumes with a home system...
7. I recorded the shows at the United Center at +12 Gain. According to the Audacity "Amplify" effect, I could have safely run at +18 Gain with 6 dB to spare.
Now I just need to get a locking 3.5mm plug and I'm all set!
