![]() ![]() or I'll just buy a decent amp to pair up instead. Thank you guys, hopefully it won't blow up after some tinkering. This whole shenanigans really might be due to a bad ether cable, but I can't really get decent volume out of it even without shorts and on unbalanced. Will measure op amp voltage, temps and write back - should be something simple. and solder a SON hotswap bed, a small fan and put a rad on top of it, just to be sure. Just clarifying what's considered "normal" for such chip package. It's also possible to desolder SON's with an inductive soldering iron (OK International's METCAL MX-5200 and similar), which are about 1-1.5k$+ with all the tips. It's possible to desolder SON's with an infrared heat station (weller WQB 4000 or similar), but there's still a small chance of damaging, and they can get somewhere between 7K-25K$ easily. SON packages are fit for one time job only because they're used in thermal sensitive applications. I suppose its a SON (DRG / WGON or similar) package. > This chip is NOT replaceable with usual soldering tools, don't anybody try.

That's why you'll need to preheat the board first to 120-170 deg c at least.Ĩ-10+ layer boards can deform and can get micro-cracks without a preheating. > Heatgun doesn't work in this case, I can tell you. Local distributors and service is not that great - it's easier for me to fix existing or a buy new one completely (no guarantee that it wouldn't overheat/overload as the previous ADI-2). It would be easier for me to pinpoint and solder through the issue myself. > Contact RME service or your local distributor for advice. Yes, there was a short because I tried to Ether via pentacon and it's compatibility is bad, to say at least. > has a intermittent short, or same inside the headphones Works same as balanced, but I'm still getting overcurrent waring right after -30db on unbalanced. Had to solder a custom pentacon to 6.3 converter first > Try the Ether unbalanced on each output. ![]() ![]() There's a thermal pad underneath, that is soldered to the mainboard's internal ground layer.īefore you are able to heat up the chip enough to resolder the thermal pad, the chip is already broken. This chip is NOT replaceable with usual soldering tools, don't anybody try. When one OPA1688 broke here only HP output 1/2 didn't work.īut that might depend on how exactly it breaks. This points to a possibly healthy ADI-2 Pro, opposed to what MC diagnoses, sorry Matthias! The error doesn't show up with his Sony MDR Z7, although yuriy_yarosh didn't tell how far up he could dial the volume. If this would be the case he could save unnecessary, complicated and maybe expensive sending back and forth of ADI-2. I try to find out if something's wrong with yuriy_yarosh's Ether or it's cabling. This would be pointless - if broken, ADI-2 has to go for repair anyway. I'm not heading for finding which ADI-2 channel might be broken. It can be useful, if yuriy_yarosh follows my advice. ![]() My assumption is the detection is based on thermal temperature, and because board has pretty good thermal conduction (10-layer-board) and the two outputs are pretty nearby, one broken op-amp may cause error message on both outputs. also I never used 1/2), but both outputs suffer from this e … 48#p155848 as having both 1/2 and 3/4 failed is rare. My previous machine has one broken op-amp (this is my assumption. If the error appears on both ADI outputs, try with only left and only right cup plugged in, still unbalanced. ![]()
