Basic Principles of PA Mixing

The fou r Ou tp u t Grou p s p rovid e su bm ixing to the Mix L/ R ou tp u ts or m ay feed external equ ip m ent d irectly. Each incorp orates stereo p anning and PFL m onitoring or bargrap h m etering and inclu d es an external Retu rn inp u t for effects or su bm ixing from external sou rces.

The Master section p rovid es m aster level control for the Left, Right, Mono and Au xiliary Send bu sses, w ith sep arate AFL m onitoring on each Au xiliary Send and the Mono ou tp u t.

The Mix L/ R and Grou p ou tp u ts all have insert p oints for the connection of external signal p rocessing.

Com p rehensive Talkback facilities are p rovid ed , w hich allow an external talkback m icrop hone to be rou ted to Mix L/ R, Grou p s and Au xes 1 & 2 as requ ired . Six 12-segm ent, 3-colou r p eak read ing LED bargrap h m eters p rovid e clear d isp lay of Mix L/ R, Grou p and PFL signals. Pressing any PFL or AFL sw itch p u ts the selected signal onto both sid es of the head p hones ou tp u t, and the right bargrap h m eter.

This ju st isn’t tru e any m ore. The sou nd system and the sou nd engineer have becom e an integral p art of the p erform ance, and the artists are heavily d ep end ent on the op erator’s skill and the qu ality of the equ ip m ent.
