Allperceptualcodershavetoomuchdelayfortalentonremotetohearthemselvesviaaround‐

triploopwithoutan"echo"thatcanheannoyinganddisorienting.Therefore,aspecialmix‐

minus(sometimescalleda"clearfeed"or"mix‐minusone")arrangementisrequired–exactly

thesameashasbeenuse

dwithsatellitelinkedremotesforyears.TheEuropeanterm“mix

minusone”isclearerinthemosttypicalsituation.

Theprincipleisthis:Theremotetalentdoesnothearhimselfviathestudiocuereturn.Rather,

hismicrophoneismixedlocallywithastudiofeedthathasevery
