I have 12 consoles hooked to my TV all at once. Among them is the PSOne (mini). For some reason the sound comes in way too low. I have tried swaping A/V cables and no change. When I play any old-school system like the NES or Master System, I only need the TV volume on 15-20, but why do I need to crank it up to 40 for the PSOne? Any thoughts? It is bugging the hell out of me.
