I'm gonna go ahead and assume it's a crossover for some sort of "audio signal"... But what do I know, I'm just the drummer.










Seriously I know it's a Symertrix but don't know the exact model number. It's for the mains for out rehearsal PA. Because the mains are coupled with subs.

And quite a handsome looking couple, I might add...

I knew someone would bite I just did not think that it would be you and my response was already pre-programmed, so there ya have it.

The point of my post was to demonstrate that analog based crossovers typically have a potentiometer that sweeps the crossover point this is done by changing a single resistance pint in the network.

Some ,in my opinion, better designs, require you to change the heart of the network circuit in order to change the frequency in the process changing out many more components.

I believe that the former method is a quality trade off for convenience.
