dbx 3bx series 2 question
My dbx 3bx series 2 device came without a manual.
It has a switch labeled "pre" and "post" that seems to enact two different modes of dynamic range enhancement.
I have some theories, but can anyone for certain explain to me exactly what the two modes are, how each works differently, and maybe some examples of when to use either to better effect?
Thanks in advance for any information you can share.
