I've purchased two gen 3 helix 9's recently. I see in the manual and online that when you pull up setup options for si/di that there should be an option to adjust your sharpness. It seems like it's under 'DI ENHANCE' or 'SI ENHANCE', but I don't see the enhance option on the menu. Is there something I need to do to make that option appear or is it that the new helix 9s don't have the option to adjust sharpness? Anyone have an answer to this?
