I'm running a recording test right now w/ the JB3 being powered by the Power Plant external batt.
I'm running analog-in on the JB3, feeding a show I recorded on my MD recorder a while back. This was done so I could monitor the recording time w/ the time elapsed on the MD to make sure the running clock kept up OK. So, basically I'm going MD (headphone out) > JB3 (analog-in @ .wav 44.1kHz.)
I'm only 10mins into it, but it seems to be just fine so far.
One strange thing is that the icon that appears on the lower left corner of the JB3 screen that displays either the battery meter or the "plug" showing external power, is showing the "plug" for external power, but it blinks on and off every 10 seconds or so. This doesnt seem to have any effect on the recording so far though. Strange......
I'm going to let this run for a full 3hrs (max on the JB3) and see what happens. If the first 3hrs goes by w/o a problem, I'll try another 3hrs again tomorrow night.
Everyone cross your fingers.
