With Scarlett 18i20’s dual ADAT optical In and Out ports, you can expand your recording and mixing capabilities, adding up to eight further inputs and outputs at 48kHz or 96kHz via a mic pre such as Scarlett OctoPre or Scarlett OctoPre Dynamic, or four channels at 192kHz. That’s more than enough channels to mic up the whole band and route a full mix to a console or summing box.
