Question

There's a big difference in the main volume knob respons on my Studio 192 as compared with my Audiobox 1818. I have to turn it much more clockwise in order to get the same volume. Is it something wrong with my Studio 192 or is it normal and if so why?

Answer 1

The Studio 192 use different component than the AudioBox 1818.  There are designed with different specifications.

It would be normal for them to be different.

However, if either device seems to behave or function poorly by themselves, then you should log in to your Presonus Account and create a Support Ticket so that a tech can assist you.
