final output.Exa m ple 4:Stereo RecordingThe console may also be used for 2-Track or basic multitrackrecording <strong>live</strong> or in the studio. The set up is similar to theprevious examples but with the Mix L/ R Output feeding a2-track Tape Machine. Aux 1 is used to provide artistsfoldback on headphones, and Aux 3 and 4 feed a reverb unit2 TRACK TAPEMACHINEREVERBwhich is returned to the console on RET1 and RET2.Exa m ple 5:Multitra ck RecordingIn this last example the mixer is connected to a multitracktape machines, and the main outputs to a 2-track machine formixdown. Once again a compressor has been included in theinsert points.Feeds to the multitrack are taken from the channel DIRECToutputs. Outputs from tape are fed back to the channel lineinputs and can be mixed down to the stereo mix output asrequired. Aux 3 & 4 feed an effects unit as in the previousEFFECTS PROCESSORPa g e 24
CARE OF YOUR MIXERGeneral PrecautionsAvoid storing or using the mixer in conditions of excessiveheat or cold, or in positions where it is likely to be subject tovibration, dust or moisture.Keep the mixer clean using a soft dry brush, and anoccasional wipe with a damp cloth or ethyl alcohol. Do notuse any other solvents which may cause damage to paint orplastic parts.Avoid placing drinks or smoking materials on or near themixer. Sticky drinks and cigarette ash are frequent causes ofdamage to faders and switches.Regular care and inspection will be rewarded by a long lifeand maximum reliability.G lossa ryauxiliary sendbalanceclippingdB (decibel)DI(direct injection)direct outputequaliseran output from the console comprising a mix of signals fromchannels and groups derived independently of the mainstereo/ group mixes.
