I am using my PS2 as a power amp for my modelers and as an attenuator for my tube amps - my question or problem is- I use a patch bay to run all my cabs and amps and PS2 through. So I have the PS2 hooked up to the patch bay so I can plug my amp into it using the bay - I ran the line in from the PS2 to the patch bay and that defeats the other inputs for my amps - Im not trying to run both at the same time. I separately use the power amp in the PS2 for my tube amps or use the PS2 (Via line in) power amp for my modelers. Is there a different way I could wire the PS2 to my patch bay so I can use it hard wired to the patch bay?
