Just picked up a 4 x 1 HDMI switcher by Psyclone - like it so far. One problem though - picked up last unit Best Buy had, which was a floor model, and consequently, they didn't have instruction manual for it. I'm having problems with 2 things: one, how to edit my input names on the LCD screen, and the other, recommended "gain" settings. Any help would be much appreciated. I see the "edit" button on the unit itself, and I've pressed it, but I don't have any idea of how to actually change the names of the inputs. And in regarrdws to the gain, does leaving it on the factory pre-set recommended, or are those of you out there who own this unit been jacking up the gain? Anyway, thanks for your time!
