UR824 + SPL Surround Monitor Controler Model 2489

Hi guys!

I used to measure my studios SPL response using a RME HDSPe with the SPL Surround Monitor Controller. I only had the SPL’s knob to move (and mark) to my desired SPL levels. I knew that -0dB coming out of RME was a certain SPL value.

Now, I don’t have the RME and we bought a UR824. It has a volume knob too. So my question is:

It’s more pratical to have the UR824 on the maximum level and regulate my monitor levels with the SPL controller. Does the UR824 on maximum level affect anything on my monitoring?

Thanks in advance!
