A heads up- Check the retaining ring that secures the PR2's input jack for tightness. If loose, tighten it before problems arise. It's the part that transfers mechanical load from the cable and miniplug through the locking input jack to the recorder's housing, relieving stress on the jack to PCB solder joints.
The problem- I had signal intermittency problems with one of two PR-2s on the last two outings. Suspected either the Y adapter I was using (2x microdot > locking mini-plug) or a failure of the input jack solder joints to the PCB. Upon a more thorough check last night, the Y-adapter checked out fine, but the input jack on the PR-2 seemed slightly loose. No problem recording while the unit sits still, but bumping or handling the plug caused intermittency. Took the small back cover just above the battery door off, and was about to begin disassembly to check the the jack's electrical connections to the PCB, when I more closely inspected the two jacks with an eye toward disassembly and noticed they both have retaining rings which secure them to the housing of the recorder. It was clear I'd need to remove both in order to remove the PCB, so I grabbed a safety pin and manipulated the slotted retaining rings. Sure enough, the one securing the input jack was loose. The other, and both on the second PR-2 were tight. So I first tightened down the retaining ring and checked for intermittency (visually using the meters) and found none, even when manipulating the locked in plug. So I made sure the retaining ring was as tight as I could manage using the safety pin, and just left it like that for now.
Is the tightened retaining ring simply holding a broken solder joint in firm electrical contact? Dunno. Rather than disassemble prior to an upcoming show and risk nullifying the warranty, I decided I'll do a few listening checks and if all seems good I'll run it this way for the upcoming show. After that I'll contact Deity about repair or replacement under warranty.
Check that ring before your's develops problems.
