INTRODUCTION Congra tu lation s on yo ur purc has e o f a SP IRIT Monitor mi xer. Owning a Soundcra f t conso le brings you t he expe rtise an d support of one of the industry’s leading manufacturers a n d the res ult s of o ver 17 yea rs exp erience supporting s ome of the biggest name s in the business .
Abov e a ll, rem em ber that yo ur SPIRIT m ixer is designed to extend yo ur creativit y. The mo re you e xplore the controls and the effec t they have on the sound output, the m ore you wi l l a ppreciate th e f l e xi bili t y offered by yo ur SP IR IT Monitor mixer.
The mixer is split into two se ctions. The Inputs rece ive, mat ch and process individual source s ignals, and dist ributes them at precise mix le vels to a c hoice of Monit or Outp uts .
The Wedge o utput refers to the engine er’s own mon itoring output, which will typicall y fee d a flo or-mo unted ‘wedge - shaped’ s peaker v ia a suitable powe r amplifier.
GETTING STA RTED CONN ECTIO NS AND CONN ECTO RS Althou gh this may seem a s imple s u bject, fa ul ty co nne ctors a nd cabli n g are the s ource of most s ound system prob lems . Correct ly- made cables of the pro per typ e, with the right co nnectors for the job will en s ure peak per fo rman ce f rom your system with minimum noise pick-up.
Balanc ed an d Unbala nced All ch annel inputs are balan ced, i.e. there are s eparate +ve(hot) and -ve (cold) w i re s for eac h signal plu s a grou nd. The design o f the d if ferential inp ut amplifiers is s uch that in- terference picked up on these wires is cancelled out.
Avoid run ning audio c abl e s or placing audio eq uipment, close t o th y ristor dimm er u nits or power cables. Noise immun i ty is imp roved significantly by th e use of lo w impedance s ources , such as goo d quality profes siona l micro- phones o r the o utpu ts from most modern a udio equipm ent.
The Bloc k Diagra m is a repres entative sketch of all the c om- ponent s of the cons ole, sh o wing how they conne ct toget her and how t he signal f l ows thro ugh the s ystem.
GETTING TO KNOW YOUR CONSOL E FACILITIES Refer to the fol d -o ut front pane l diagram at the rear of this manua l, which sh ows the co ntrol functions on the SPIR IT Monitor . Each facility is des cribed belo w, and is identified b y a reference nu mber.
The insert po int allows limiters , c o m pressors and other signa l proces sing units to be added as required to particular inpu t channe ls a nd bec aus e it is loc ated PRE EQ, noise gene rate d by the ext ernal equipm e nt may be reduced by a s mall amou nt of H.
8. EQUALISER The Equalis er(E Q ) comprise s three sec tions. The upper co n- trol provides H.F.(treble) bo o st and cut of +/-15dB. The lower two pairs of knobs are arran ged as a cut /boo st c on tro l (lower knob) of +/- 1 5dB , and a S WEEP(frequency) control which dete rmines at whic h frequenc y the boost/c ut action will be centred.

cessful sound mixing. The aim sho uld be t o place the microphone as clos e as physi- cally p ossibl e to the sourc e, to cut out unwanted surro unding sounds, a llow a lower gain se tti ng on the mixer and avoid feedback. Also a well-chosen and well- p l aced micro phone should no t need any a pprec iabl e equa lisatio n.
CARE OF YOUR MIX ER Gene ral Prec autions Avoid st oring or using the mixer in co nditions of exces sive heat o r cold, or in p ositions where it is likely t o b e subject to vibration , dust or mo isture. Keep the mixer c lean using a s oft dry brush, and a n occa- sional wipe w i t h a damp cloth or ethyl alcohol .
