The Mixer As one w ou ld exp ect, the m ain p u rp ose of the m ixer is to
com bine sou nd s, bu t u nd er p recise and sm ooth control. This
is w hy long-throw fad ers are essential on any p rofessional
p rod u ct. The fad ers p rovid e you w ith clear and instinctive
control of the final sou nd balance and like an artist p laying an
instru m ent you shou ld listen to the effect of you r fad er
m ovem ents, not look at you r hand s.
You r SPIRIT LIVE 4 m ixer accep ts a w id e range of inp u t
signals via a m icrop hone inp u t, for very low level signals, or a
line inp u t, for higher level signals from , for instance, tap e
m achines, effects p rocessors, etc.
The m ixer is sp lit into tw o sections. The Inputs receive, m atch
and p rocess ind ivid u al sou rce signals, and d istribu te them at
p recise m ix levels to either a stereo Mix ou tp u t or to one of
the Groups. The Master section allow s overall level control
of all ou tp u ts, and p rovid es m onitoring of the au d io signal at
m any p oints in the m ixer, either on head p hones or m eters.
The Equaliser controls are the m ost flexible and p otentially
d estru ctive featu re of the m ixer. They have a sim ilar effect on
the frequ ency resp onse of the inp u t channel as the tone
controls on a hi-fi system , bu t w ith m u ch greater p recision,
and allow p articu lar characteristics of the inp u t signal to be
em p hasised or red u ced . It is very im p ortant that you becom e
fam iliar w ith the effect each control has on the sou nd and this
is best achieved by sp end ing tim e listening to the effect of each
control on a w ell-know n track p layed throu gh the m ixer.
The Auxiliary Sends p rovid e a w ay of rou ting the inp u t
signals to a nu m ber of second ary ou tp u ts, for artists fold back,
echo u nits or ad d itional sp eaker ou tp u ts.
The Pan control ad ju sts the p osition of the inp u t signal w ithin
the stereo m ix, and can be sw ep t from fu ll left, throu gh to fu ll
right. This allow s p articu lar artists to retain their correct
sp atial p osition w ithin the m ix, and can be valu able for live
effects.
Pre-Fade-Listen(PFL) allow s you to m onitor the signal at
m any p oints in the m ixer. Pressing any PFL sw itch p laces the
signal at that p articu lar p oint onto the head p hones and the
right m eter, to check the qu ality of the signal or to p in-p oint
p roblem s. Using PFL w ill not affect the signals on the ou tp u ts
