Appendix A: Signal Paths

Many   users   of   the    Omnia.9    will   be    content   with   plugging   it   in,   making   the   necessary   I/O
connections, picking   a   preset, then sitting   back to enjoy the   amazing aural delights and effortless
dial dominance it provides.    Some will   want to make changes to achieve   a   truly custom sound.    Still
others will   want to   explore every nook and   cranny of the menu   system to   discover every available
control (there   are   4,177 points of adjustment when all features and cores are   active   – best to   pull up
a comfy chair and   get a pot of coffee going).   And   then   there are those who   will want to   know more
about   how   stuff   gets   done.       It   is   for   that   crowd    that   we   have   provided    the   following   flowcharts
showing various signal   paths within Omnia.9.Physical Inputs
