Where it goes on stage
A plot earns its keep by settling positions before anyone opens a case. Backline sits upstage, angled slightly inward so the player hears it without firing straight into an open vocal mic. Leave a working gap behind the cabinet for the mic stand and the cable. Anything unusual about the position belongs in the plot notes, so the drawing carries its own explanation.
What the crew needs to know
Worth confirming in the advance. Say whether the amp travels with the band or comes from the house. Backline rental decisions get made off this drawing, so an unlabelled cabinet becomes a phone call.
On the input list
Mesa Mark V + 4x12 produces one channel on the input list, defaulting to a Dynamic input, a short boom stand and phantom power off. It sorts at position 3 in the drums first, vocals last channel order that front of house engineers expect. Change any of it per plot; the default just means you rarely have to.
Console exports
The input list behind the plot exports as a Behringer X32 or Midas M32 scene file, a Behringer Wing scene, or CSV channel names for Allen and Heath dLive, Avantis, and SQ, DiGiCo, and Yamaha CL and QL desks. See the console guides.
