Topic: ADI-8 DS AD Conversion

Hello RME users,

currently comparing two RME AD/DA converters (ADI-8 DS and ADI-8 QS), but I cannot notice any difference in the AD conversion between these two devices except sample rate. The technical specs seem to be quite identical in this case, whereas in the DA conversion there's a larger difference. I need a AD/DA converter primarily for recording purposes at 96 kHz. For monitoring I have another device. My question is, do I overlook something or do they share similar AD converters?

Thank you for your help!

Re: ADI-8 DS AD Conversion

The QS has the better analog input stage (more flexible, Limiter plus +24 dBu), and the better converter chip (CS5381), specced with about 4 dB less noise and 5 dB less THD than the AK5392 used in the DS. In real world you won't notice a difference because both exceed the quality of the source signal/audio that you want to record. Or in other words - the difference caused by the AD conversion is inaudble.

That said just use what fits the purpose. Both have a very different feature set.

Re: ADI-8 DS AD Conversion

There are 2 valid reasons to go for the QS. You need 192Khz or you need to impress your clients. For the last one, how much is that worth for you and your business?

Re: ADI-8 DS AD Conversion

Thank you for the answers!
Have the AD converter chips changed during the production period of ADI-8 DS?
In other words, has there ever been an update from MK1 to MK2?
So far I can find only information about the original Adi-8 DS and the DS MkIII version.

Re: ADI-8 DS AD Conversion

No. Only the position of the COPY MODE switch changed on the front. Therefore the unit was publicly not called MKII. No real internal change.
