There wa a time when the P.A. y tem and the operator exi ted only to increa e the overall volume of the performer , o that they could be heard in a large room or
above high ambient noi e level . Thi ju t i nt true any more. The ound y tem and the
ound engineer have become an integral part of the performance, and the arti t are
heavily dependent on the operator kill and the quality of the equipment.
The following introduction to the ba ic of mixing are included for the benefit of
tho e u er who may not have any ignificant familiarity with ound equipment, and who
are baffled by the endle jargon u ed by engineer and arti t alike.
TThhee MMiixxeerr
A one would expect, the main purpo e of the mixer i to combine ound , but under
preci e control. Thi i why long-throw fader are e ential on any profe ional mixer, to
give a re pon ive and mooth feel to the operator. The fader provide you with clear
and in tinctive control of the final ound balance and like an arti t playing an in trument
you hould li ten to the effect of your fader movement , not look at your hand .
Your SPIRIT LIVE 42mixer accept a wide range of input ignal via the microphone
input, for very low level ignal , or a line input, for higher level ignal from, for in tance,
tape machine , effect proce or , etc.
The mixer i plit into two ection . The Inputs receive, match and proce individ-
ual ource ignal , and di tribute them at preci e mix level to either a tereo Mix output
or to one of the Groups. The Master ection allow overall level control of all output ,
and provide monitoring of the audio ignal at many point in the mixer, either on head-
phone or meter .
The Equaliser control are the mo t flexible and potentially de tructive feature of
the mixer. They have a imilar effect on the frequency re pon e of the input channel a
the tone control on a hi-fi y tem, but with much greater preci ion, and allow particular
characteri tic of the input ignal to be empha i ed or reduced. It i very important that
you become familiar with the effect each control ha on the ound and thi i be t
achieved by pending time li tening to the effect of each control on a well-known track
played through the mixer.
The Auxiliary Sends provide a way of routing the input ignal to a number of ec-
ondary output , for arti t foldback, echo unit or additional peaker output .
The Pan control adju t the po ition of the input ignal within the tereo mix, and
can be wept from full left, through to full right. Thi allow particular arti t to retain
their correct patial po ition within the mix, and can be valuable for live effect .
Pre-Fade-Li ten(PFL) allow you to monitor the ignal at many point in the mixer.
Pre ing any PFL witch place the ignal at that particular point onto the headphone
and the right meter, to check the quality of the ignal or to pin-point problem . U ing
PFL will not affect the ignal on the output from the de k.
Each mono input channel and the Mix and Group output have an Insert `A gauge
jack ocket, which i a break point in the ignal path. It allow the ignal to be taken out
of the mixer, through an external piece of equipment and then back into the mixer
directly after it original exit point. The In ert point i normally bypa ed by the `A
gauge jack ocket contact , and i only brought into operation when a plug i in erted.
Typical u e would include Effect Proce or , Limiter , additional Equali er or Delay
unit . In addition, each channel ha a Direct output which may al o be u ed to feed
external equipment uch a multitrack tape machine or effect device .

The term PRE and POST are often u ed in the context of In ert , Equali er and
Auxiliary Send , and de cribe whether that facility i placed before (Pre) or after (Po t)
another particular ection. Thi i explained further in the Glo ary.
A mixer i often judged, among t other factor , by the amount of eadroom avail-
able. Thi i a mea ure of the re erve available to cope with udden peak in the input
ignal, without di tortion cau ed by Clipping, when the ignal become o high that it
would exceed the power upply rail voltage and i a a re ult limited. Thi commonly
occur where gain etting are incorrectly et or where ource are improperly matched
to the mixer input. If the ource ignal i too high, clipping and di tortion re ult . If the
ignal i too low it become ma ked by the background noi e which i pre ent to ome
degree in all mixer . The diagram below illu trate thi point.
If the signal level is too low it may be masked
by the noise.

Accept 3-pole `A gauge jack , or 2-pole mono jack which will automatically ground
the cold input. U e the e input for ource uch a keyboard , drum machine , ynth ,
tape machine or a return from proce ing unit . The input i BALANCED for low
noi e and immunity from interference, but you can u e UNBALANCED ource by
wiring up the jack a hown, although you hould then keep cable length a hort a
po ible to minimi e interference pick-up on the cable. Note that the ring mu t be
grounded if the ource i unbalanced. Mono ource can be fed to both path by plug-

You will probably be familiar with the concept of polarity in electrical ignal and thi
i of particular importance to balanced audio ignal . Ju t a a balanced ignal i highly
effective at cancelling out unwanted interference, o two microphone picking up the
ame ignal can cancel out, or cau e eriou degradation of the ignal if one of the cable
ha the +ve and -ve wire rever ed. Thi pha e rever al can be a real problem when
microphone are clo e together and you hould therefore take care alway to connect
pin correctly when wiring audio cable . The mono input are provided with a Pha e (f)
witch to rever e the polarity of a elected input if a pha ing problem i u pected.

For optimum performance it i vital that all ignal are referenced to a olid, noi e-
free earthing point and that all ignal cable have their creen connected to ground. To
avoid earth `loop , u e balanced connection where po ible and en ure that all cable
creen and other ignal earth are connected to ground only at their ource and not at
both end .
If the u e of unbalanced connection i unavoidable, you can mimimi e noi e by fol-
lowing the e wiring guideline :
lOn INPUTS, unbalance at the ource and u e a twin, creened cable a though it
were balanced.
lOn OUTPUTS, connect the ignal to the +ve output pin, and the ground of the out-
put device to -ve. If a twin creened cable i u ed, connect the creen only at the
mixer end.
lAvoid running audio cable or placing audio equipment, clo e to thyri tor dimmer
unit or power cable .
lNoi e immunity i improved ignificantly by the u e of low impedance ource , uch
a good quality profe ional microphone or the output from mo t modern audio
equipment. Avoid cheaper high impedance microphone , which may uffer from
interference over long cable run , even with well-made cable .
