192 Crackling on two channels
Hey all. Using a 192 slaved to an Omni. Recently started getting consistent crackling from input channels 7 & 8 on the 192. Sounds much like a clock problem, but the setup is correct and channels 1-6 are clean. I've never had the box open, and I'm wondering if there separate internal cards for each channel or pair of channels? If so, it could be just a seating issue, or a simple replacement. Hoping to avoid having to ship the whole box out. Any advice from experienced users welcome.

Re: 192 Crackling on two channels
Not sure I would ship the box anywhere, but there are some things worth checking(assuming you have 2 BNC cables completing Loop Sync connections and the 192 has a Digital IO card in slot 3(IIRC, this is required). I would pull the unit out of the rack, pop the top panel and find the multi-pin connector on the Input card. Unplug it and do a thorough inspection of pins and sockets. Maybe hit it with some good contact cleaner and re-connect and test. If that makes no difference, instead of shipping the unit, I would just shop for a deal on another analog input card and replace the fouled card. If that fixes it, great. If that DOES'NT fix it, then you know its not the card, BUT, in that case, stick the old card in slot 4 and see if it works there(which might be worth a try anyway):o

Re: 192 Crackling on two channels
Hi, I have pretty much the same problem here, just bought a 192 unit of ebay with 8 a/d and 8 d/s and digital in/out, have test all the a/d and get crackling (like statics noise) on channel 1 and 2, the other 6 are perfect, i will try to dismantle the whole thing and give it a clean up, perhaps that will do the trick and i will let you know what i found. I will also try to card on slot 4 which is the slot below the digital in/out slot, right?

Re: 192 Crackling on two channels
Well, my problem seems to be spreading. Channels 7 & 8 are extremely crackly, and now channels 5 & 6 are starting to crackle. Kinda like the unit has gangrene. :( Channels 1-4 are still clean, but I'm thinking now I better get this dealt with before the whole thing takes a dive. Weird stuff.

Re: 192 Crackling on two channels
I spoke with Thermal Relief about repairing the 192, and they said they could do it but that the cost would be more than just buying another used unit. They also said replacing the malfunctioning analog input cards is such a cinch that I should do it myself, and that the cards are readily available on Ebay. I'm game for that, but I'm finding zero cards available on Ebay or anywhere else. Anybody aware of a source for old Digidesign components?
