Guys these cards are most definitely made for High Resolution inputs, Kieth is quite correct (well to my old ears) when he says they are just bits of wire with gain. Dave Meadowcroft is spot on when he says on premium balanced inputs some form of adjustment IS included to ensure the tollerances of the componants are negated quite rightly a sign of care and quality by the design and manufacturing team. Bit like “Pair Matching” of microphones.
I have been using them to record classical music off and on over the last few months (All social distancing requirements etc complied with) now I would find it hard to revert back to “Non Prime” inputs for my reference and main input channels at least. Historically good mic inputs on analogue desks were expensive, boutique channel strips are not cheap, high resolution microphones cost serious money. I think the Prime card on that basis is pretty good value for money, especially if you already have a DX32 as part of your inventory. They work fine with both my D-Live and my SQ5 (Thanks to everything I/O) Makes me a happy camper (sorry User).
Regards All.
