Hi all,
a little bit confused here! 
I’ve two monitoring system on my project studio. One is an Adam a7x and the other BlueSky 5.1 with bass management control. Everything is controlled through the ControlRoom in Cubase7, so i can switch easily between the two monitoring environment.
I’ve heard that when i decrease the volume in the control room ( i didn’t touch the master, so the level are still fix) i decrease the volume output on my soundcard and i loose some dynamic on the monitor. If i use a external analogic volume control i can decrease the volume without touching the levels from the soundcard and i’ll obtain a correct bitrate/dynamic range also if i listen a lower levels.
For my setup i didn’t have this problem with the BlueSky system becouse i can use the BassManagement control, but for the Adam a7x i’m thing to buy a external volume control (such as the SPL).
is that true? is it a good explanation?
Please give me some tips and feedback
