CONFIGURATION
DESCRIPTION
OF CONSOLE
Ledbor
The 11 segmentledbar(the first led indicates
only that the powersupplyis on) is a peakreading
instrumentindicatingboth positiveand negativepeaks
which is absolutelynecessaryin modern recording.The
levelcalibrationis adjustablefrom the back of the
consolewith a multiturnpresetpotentiometer.The
ledbarreadsall signalsappearingbeforethe insertion
point of the monitor/effect
section.Thereforeall signals
that are audiblevia monitorp.f.l.This could be the
multitrackinput,the multitracksync output,the
multitrackremix,or the effect input.lt is also possible
to use the monitorsectionas an effect return without
havingto decouplethe ledbarfrom the multitrackreplay
(remix)output.Do not patchinto the effect input but
into the monitorinsertioninput with effect returns.The
ledbarcontinuesto registerthe
multitrackrecorder.
Mic
Belowthe ledbarsectionare the input circuit
controlsand switches.The first beingthe, per channel,
switchable+48V phantompowersupply.Belowthis is
the - 20 dB pad, necessaryfor extremelyhigh input
signalson the mic input.
Line
The line switchchangesthe XLR input to line
levelsensitivityand also changesthe balancedmic
inputconnectioninto an unbalancedline input.The
input sensitivityrangesfrom - 10 dBu to +20 dBu.
Remix
The remixswitch,which also activatesa line
levelinput has priolity over the line switch. The remix
input is combinedwith the sync input on the back of
the console.
Goin
The gain controlacts for the mic amplifieras a
feedbackcontroland in the line/remixmode as an input
attenuator.The mic gain rangesfrom - 20 dB to
- 64 dB whilst providingan enormousheadroomwith a
mi nim umof 40 dB.
Phose
This phasereversalswitch is active on both mic
and line/remixinputswhich proveshandy in all sorts of
recordingsituations.
HighPqssFilter
The high-passfilter is a fixed frequencyfilter
with a -3 dB turn overfrequencyat 100 Hz. The slope
is 9 dB per octave.
Equolizers

a signalthroughthe console.In fact it is possibleto
route,withoutpatching,from any input to any output.

The middlerow of masteroutputs and the row on the

of - 10 dBV on the tip of the stereoiack and + 4 dBu
on the ring. Next we have anothermasteroutput similar
to that just described.This secondoutput is intended
for use with a secondmastermachine.Below these
are the 2 stereoreturnsfor the master

machine.Thesestereojacks havean input sensitivityof
- 10 dBV on the tips and + 4 dBu on the rings.
Belowthe stereordturnsare the masterinserts and two
aux insertsand finallythe 2 C.R.M.iacks which deliver
the C.R.M.outputs.
Powersupplyconnectionis by meansof a 5 way XLR
connector.The two earth connectors(one below the
powersupplyinput socket and one in the patch bay)are
to be used whena patchbayis installedin the
mainframeto preventearth loopswhen patching. Link
the two pointswith a heavyearthing.conductor.
Pofchboy
The patchbayis modularand has provisionfor 64
break patch-pointsper module.The connections
betweenthe patch-pointsand the socket at the rear ot
the consoleare madevia two prlntedcircult boards
which haveat the back nlolex pin'connectors.
Patchingis done as follows: lt is necessaryto solder a
stereojack plug to one end of a twin screenedlead (in
which eachof the conductorsis individuallyscreened).
To the otherend soldera two pin molex female
connector.You now havethe standard4000series
internalpatchcord.
Now let's say, for instance,you want to wire the
channel1 insertionpoint to the patchbay.To do this
plug the
take a 4000seriespatch cord (Jack-Molex)
stereojack into the insertionsocketon channel 1 and
connectthe Molexfemale connectorto the pins marked
1 on the Molexstrip connectoron the rear of the desk.
In this way you can bring any in/outputjack to the
patchbayby meansof simpleexternalwiring and
furtherit is an economicalmethodwhich savestime.
A. Singlesource on singlblrqck-Recording
Themicrophoneor line signalentersthe
in/outputchannel,at the point wherethe mic/linepush
bultonwill determinethe input mode.A gain controlfor
the microphone
and line signalsis providedwith
additional- 20 dB pad for the microphonesignal.
Phasereversecan be usedon both mic and line
signals.lf necessary,
the 48 volt phantompoweringcan
be switchedon.
Firstlythe signalgoesthroughthe high-passfitter which
can be switchedin or out. After passingthroughthe
high-pass
filter it entersthe equalizersectionwhich can
also be bypassed.Afterthe e.q.the signal appearsat
the ancillaryequipmentjacksocket.This providesa
send and returnpath for the introductionof effects or
othertreatment_of
the signal.The p.f.l.switch monitors
afterthe insertionpoint,but beforethe mute switch.
Directlyafterthe mute switch(abovethe mute led) is
the long travelfader.This fadersendsthe signalvia the
channelpan-potto the master/groupbusses if
activated.
ln case of a singletrack recqrdingit is better to by-pass
the pan-potand the group-amps.
This is done simply by
not activatingany of the "to" and "from" switches.In
this way only the post faderchannelamp is directly
connectedto the multitrackinput.Thereare two ways
of monitoringthe signal,directlyfrom the channel:
- by pushingthe masterroutingswitch,which leaves
the monitorsectionfree for otherpurposes.
- the 2nd way is to use the monitorfader and its
associatedpan-potwhichfeedsthe signal directlyto
the mastermix busses,if the monitormute is not
activated.
It is an absolutenecessityto mute everyunused
monitorchannelin orderto achievebest overallsignal
to noiseratio in the mastermix busses.This muting
removesthe mix resistorsfrom the buss and thereby
providesa lowernoisegain.In an unusedchannelthe
masterswitchhas to be inactiveto achievebest signal
to noiseperformance.
Whenno effectswitch is activatedthe led bargraphwill
readthe signalgoingto the multitrack.Aux sendscan
best be usedpre/postfrom the monitorfader.In this
configuration
the aux sendsare also availablein the
sync mode.lf you wish to monitorfrom the channelyou
haveto pushthe aux to channelswitch.
The standardway to recordin one channelis to drive
the multitrackmachineas hardas possibleand to
monitorthe signalthroughthe small fader.Both in the
recordingmodeand in the sync mode.

the final end mix will haveto be made.All
the remixswitcheshaveto be activatedand the master

is a basicset up for B- 16- 24 tracks into 2. Ensure
that unusedchannelshavetheir masterswitchesin the
off positionand that the mutingswitchesin the
monitoringsectionare in the "mute" mode to optimise
signalto noise ratio.
Eachchannelmonitorsection(lightcoloured)has an

PAN POTDeze knop bepaald per kanaal de plaats van het
signaal in het stereo beeld. Dat is van volledig
links/rechts tot elke positie ertussen. Het signaal
wordt dus verdeeld tussen de even en oneven
subgroepen
alsmede
de
links/rechts
masteruitgangen. Wanneer de pan pot centraal
staat wordt het signaal 4,5 dB verzwakt.
M O N I T O RS E C T I E De monitor sectie is wit. Het vergemakkelijkt de
bedieninE en maakt het paneel overzichtelijker. De
volledige monitoring in een kanaal wordt door
deze sectie geregeld.
SYNCDe sync-schakelaar in de monitorsectie bepaald
het opnemen cq weergeven van de meersporen
recorder
in
de
monitorsectie.
Wanneer de
schakelaar ingedrukt is geeft dit aan, dat de
monitor sectie in het kanaal automatisch wordt
geschakeld van de ingang naar de uitgang van de
recorder.
EFFECTDe

returns als de
achterzijde van
PFL en MUTE (monitor)
Via de pfl schakelaar luistert U v66r de fader
naar het signaal dat komt vanaf de kanaalfader of
van de meersporen recorder, alsmede de effect
ingang. Deze pfl is auto-type, dat betekent dat
de pfl automatisch de stereomaster van de monitor
afschakelt en deze vervangt door het gekozen
kanaal.
De mute toets onderbreekt het signaal, komende
van de multitrack sync of effect inputs. De pfl
wordt niet door de mute beinvloed.
F A D E R M O NI T O R In de monitor sectie is een kleine, 58 frh,
carbontrack fader gemonteerd. U heeft l0 dB
versterking ter beschikking in de versterker die
na de monitorfader volgt.
EQUALIZERSDe equalizer van de series 4000 is niet gecompliceerd maar
wel uitermate effectief.
De signaalweg is minimaal
een
uistekende
ruJs verhouding
waardoor
signial
verkregen wordt. De viervoudige equalizer omvat het hele
audiospectrum.
De
laag cq
hoogsectie heeft
zijn
kantelpunten op resp. 60 Hz en 12 kHz. De high-mid
toonregeling loopt van I tot l0 kHz terwijl de low-mid een
bereik heeft van 100 Hz tot I kHz. De kantelpunten ziin
zeer muzikaal ontworpen; ze zullen U verrassen!
Mocht extra toonregeling nodig zijn: een insertie punt is
gemonteerd direct
na de toonregelsectie. De gehele
toonregeling
op
een
kanaal
kah
d.m.v.
een
bypass-schakelaar overbrugd worden. Een led geeft aan
of zij al dan niet is ingeschakeld.
AUXDe series 4000 heeft in totaal 6 effectsends te bieden
wetke ruim genoeg zijn voor de meest uitgebreide
remixsessies. Ze ziin per paar pre/post de monitor fader
schakelbaar. Wanner de aux-to-channel wordt ingedrukt
zijn de effectsends pre-post de kanaalfader schakelbaar.
Staat deze schakelaar niet ingedrukt dan is het mogelijk
pre/post de monitorfader een signaal aan de muzikanten in
de studio aan te bieden. (=foldback) Mede is het mogelijk
een effectapparaat aan te sturen voor of na het signaal
van de multitrack recorder.
AUX-TO-CHANNELDeze schakeling zorgt erv(x)r dat alle aux sends pre/post
de kanaalfader schakelbaar ziin, iets wat tijdens de
remix-sessie noodzakelijk is.
SUBGROUPINGHet maken van subgroeperl in de series 4000 gebeurt op
een vrij onorthodoxe manier en verlangt een andere
manier van denken van de technicus. Het basisidee is om
all66n daar subgroepen te hebben waar men ze ook nodig
heeft. Dit betekent dat het mogelijk is op ieder gewenst
kanaal een subgroep te vormen. DeR noemt dit FSS;
Floating Subgroup System! Se series 4000 heeft 4
versterkers.
Dat is voldoende omdat de
subgroep
subgroepen dus overal inzetbaar zijn.
U kunt de
subgroepen naar de ingangen maar ook naar de uitgangen
overal in het mengpaneel schakelen. De routing van het
kanaal wordt verder beschreven onder het hoofdstuk I
Meerdere Signalen op een of twee Sporenr. Dit zwevendd
subgroep systeem bespaart erg veel schakelaars en andere
componenten vergeleken met andere in-line mengtafels. De
bedrijfszekerheid wordt hierdoor allen maar vergroot.
Uiteraard is het mogelijk om naast de subgroepen de
mastersectie gelijktijdig aan te sturen.

LED BARDe 11 segments led bar (de onderste led geeft aan of
de tafel is ingeschakeld) is een peak led bar die
zowel positieve als negatieve peaken aangeeft; iets
wat
absoluut
noodzakelijk
is
in
moderne
studiotechnieken. De level calibratie is instelbaar aan
de achterzijde van het kanaal. De led bar geeft de
niveaus van alle signalen weer welke vddr het
insertiepunt
van
de
monitorsectie
de
tafel
binnenkomen. Dat zijn dus alle signalen die U kunt
beluisteren via de monitor pfl. Dit kunnen zijn: de
multitrack input,
de multitrack-sync output, de
multitrack remix of de effect-input.
Het is ook
mogelijk
monitor
de
sectie als effectinput
te
gebruiken zonder dat de led bar wordt losgekoppeld
van het recordersignaal. Patch in dat geval niet in
de effectinput maar in de monitor insertie jack. Het
blijft dan mogelijk het niveau van het recordersignaal
af te lezen.
MtcOnder de led bar vindt U de bedieningsorganen van
de microfoon ingang. De bovenste schakelaar geeft
de mogelijkheid de 48 V phantoomvoeding per kanaal
aan/uit te schakelen. Hieronder bevindt zich de -20
dB schakeling welke gebruikt
kan worden om
oversturing van het microfoonkanaal te voorkomen.
LINE_
De line schakelaar schakelt de micrtofooningang om
naar line-gevoeligheid en impedantie. (resp. -10
6gu/+20 dBu, 10 kOhm)
REMI XIn feite is de remix-schakelaar niets anders dan een
line-schakelaar met een prioriteit boven de normale
line ingang. De remix input is gecombineerd met de
sync-input op de achterzijde van het paneel.
G A IN De gain regelaar regelt de mate van versterking of
verzwakking
van
het
aangeboden signaal.
De
microfoongevoeligheid reikt van -20 dB tot -64 dB,
met een uitsturingsmarge van meer dan 40 dB.
