Topic: SD LD filter on my AK4490 equipped RME ADI-2 DAC?

Hello forum members,

After I installed the latest update to this date on my AK4490 equipped RME ADI-2 DAC, the DA filter SD LD is available in the settings. This should not be available on my DAC chip from my knowledge, only the later AK4493 supports it.

Have the RME team really done the impossible and added it in the older DAC chip or is this a bug?

That's a bug in the firmware, and one of the reasons we did not promote this update for ADI-2s. What astonishes me more is that you did not notice volume is down 2.5 dB...

An offical release is expected in the next days, which handles the old ADI-2 DAC correctly and adds the new USB Loopback feature. To go back to the working firmware 35/35 use this fut:

Thanks for the clarification.

I was away for two weeks without using the unit and installed the latest update immediately when I returned home, I had no point of reference to how loud it was before the update because of the time span.
