AVID HD I/O CARD (A/D Input) Question

AVID HD I/O CARD (A/D Input) Question

Electronic experts out there I have a question. I have a two year old AVID HD I/O that I purchased in the 8X8X8 configuration. I'm ditching the Digital Card I/O to add 8 more analog inputs. I purchased a used AVID HD I/O AD Card on Ebay from a very reputable seller. The purchased card has different colored circuitry than the one that came installed in the 8X8X8. Any idea why that would be? I'm not an electrician so I can't tell you what those circuit parts are component-wise. Haven't installed yet to test. Just the curiosity in me …

See Below

Here for the gear

Although that might seem a bit fishy, it's pretty common. Capacitor manufacturers change product colors, different product lines (with otherwise identical values and specs) might have different package colors, Avid may have had to switch suppliers at some point during their manufacturing run (again, using the exact same value/spec capacitors, but that might look a bit different on the outside), and the last option is that someone is making completely working counterfeit I/O cards (EXTREMELY unlikely, but I suppose it's possible).

Given that you got them from a reputable dealer, I wouldn't worry much at all. If you want, try to contact engineering and manufacturing at Avid (good luck...) and see if they can confirm a part / supplier change that would account for your different cap colors.

If you really wanna get picky, run a music signal out thru your analog outs, and loop it back into your old input card, and then again into the new input card. Do a null test and see if the new card really differs from the old one.

Thanks...can't imagine a clone that complex but those Chinese can dup anything

It'll be fine - just different suppliers of components.

The chances of someone being bothered enough to try to scam on a niche product like an HD input card are incredibly low. The chances of a functioning clone even more so!

Quick update. The "used" card is a "Rev B" according to silkscreening on the PCB board. The original card is a "Rev A"...
