USING YO UR SPIRIT LIVE 4 CONSOLE
The final sound from y our P.A. system can only ever be as
good as the quality of the source signal. Just as you need to
become familiar with the control functions of your mixer, so
you m ust re cognise th e impor tance of cor rect choice o f i n puts,
microphone placement and input channel settings. However,
no amount of careful setting up can tak e account of the
spontaneity and u npr edictability of live performance and the
mixer must be set up to p rovide ‘spare’ control range to
compensate for changing microphone position and the
absor ption e ffect of a larg e audie nce (differ ent acou stic
characteristics from sound check to show).
The front panel drawing inside the rear cover shows
typical initial control positions which may be found a
useful guide to setting up the mixer for the first time.

Initia l Set Up

The diagram on page 5 demonstrated how the m atching of
input gain to the signal source was crucial to avoid d istortion
at one extreme an d excessive noise at the other. Set up
indiv idual inp ut chann el as follows:
•Connect the input required (microphone, keyboard etc.)
Note: Phantom pow ered mics should be connected before
the +48V i s switche d on.
•Set Mast er fader s at 0, inp ut fade rs at 0, and set po wer
amp lifier levels to ab out 70%.
•Provide a typical performance level signal and press the
PFL button on the particular channel, monitoring the level
on the right-hand meter.
•Adjust the input gain un til the meter is just reaching the
amber section (0dB) at a typical maximum source level.
This all ows suffici ent head room to accomm odate p eaks
and establishes t he maximu m level for n ormal op eration
(but see note below).
•Repea t this pr ocedur e on oth er chann els as req uired. A s
more channels are added to the mix, the meters may move
into th e red section . Adjust the overall level u sing the
Maste r Faders if necessar y.
