issenttotheleftversustheright
outputs.
Withtheknobpannedhardleft,
the signal feeds the main left,
group1,orgroup3busses,
dependingonthesettingofthe
assign switches [42]. With the knob
pannedhardright,thesignalfeeds
themainright,group2,orgroup4
busses,againdependentonthe
setting of the assign switches [42].
Thebalancecontrolemploysa
designcalled“ConstantLoudness.”
Ifyouhaveachannelpannedhard
left(orright)andthenpantothe
center,thesignalisattenuated
about3dBtomaintainthesame
apparentloudness.Otherwise,it
wouldmakethesoundappearmuch
louderwhenpannedcenter.This
controlisproperlycalled“BAL”for
balance in the stereo channels.
