USING YOUR SPIRIT LIVE 4 CONSOLE

The final sou nd from you r P.A. system can only ever be as
good as the qu ality of the sou rce signal. Ju st as you need to
becom e fam iliar w ith the control fu nctions of you r m ixer, so
you m u st recognise the im portance of correct choice of inpu ts,
m icrophone placem ent and inp u t channel settings. H ow ever,
no am ou nt of carefu l setting u p can take accou nt of the
spontaneity and u npred ictability of live perform ance and the
m ixer m u st be set u p to provid e 'sp are' control range to
com pensate for changing m icrophone position and the
absorp tion effect of a large au d ience (d ifferent acou stic
characteristics from sou nd 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.
The d iagram on page 5 d em onstrated how the m atching of
inpu t gain to the signal sou rce w as cru cial to avoid d istortion
at one extrem e and excessive noise at the other.
ind ivid u al inpu t channel as follow s:
• Connect the input required (m icrophone, keyboard etc.)
N ote: Phantom pow ered m ics should be connected before
the +48V is sw itched on.
• Set Master fad ers at 0, input fad ers at 0, and set pow er
am plifier levels to about 70%.
• Provid e a typical performance level signal and press the
PFL bu tton on the particular channel, monitoring the level
on the right-hand meter.
• Ad just the input gain until the meter is just reaching the
am ber section (0dB) at a typical maximum source level.
This allow s sufficient head room to accom mod ate peaks
and establishes the maxim um level for normal operation
(but see note below ).
• Repeat this proced ure on other channels as required . As
m ore channels are ad d ed to the m ix, the meters may m ove
into the red section. Ad just the overall level using the
Master Fad ers if necessary.
