002R Volume knob=Control24 Volume knob??

[Gothboy]

.....or should I reverse that and ask it the other way around? I visited a friends' studio recently where we did some critical listening to some of my sessions. He has a Control 24 and I have a 002R. The main volume knob on the 24 has a 0 point at 2:00. The 002R doesn't have the markings around the knob...but are they basicly the same thing...are they synonymous with each other? Did they omit the markings because the levels put out by each unit is different?
We had the sound in the room up around the 12:00 area through 8" KRKs that was super huge and loud and I never put my 002R that loud.
