Shouldn’t law enforcement information be public anyway? I didn’t know there were secret police in America.

As someone in a similar boat as OP, I would love to know more!

Turns out early audio consoles with stereo didn’t have a pan knob. They had a pan switch. So choices were limited to left, right, or center (mono).

Wasn’t til later that the pan pot was invented allowing incremental panning and true stereo mixing.
