High level outputs

If i use the high levels inputs to route the signal to the subwoofer and the outputs to my main speakers, does the settings in the sub crossover affect the output to the main speakers? I need the sub crossover to filter the low frecuencies to my main speakers

It's not specifically said in the manual, but I think the crossover still works for the high level inputs. You might want to confirm with Outlaw , though.

Cat, what brand of receiver/processor are you using?

I'm planning using it for my store office computer with an old yamaha receiver and a pair of axiom millenia m2i speakers

I'm assuming you mean a stereo receiver with no sub-out?

Yes it's a really old yamaha receiver aka 1982
