TABLE OF CONTENTS

Feature OverviewThe SP / TC / GT features listed beloware common to all Century Series Consoles.

• SSM/PMI High quality preamplifiers on balanced micro-phone/line inputs and on all balanced outputs for uncompro-mised audio quality and reliability. All IC’s within the audiopath are socket mounted for easy upgrade or service.

• 48 Volt switchable phantom power on all microphone inputs.

• Optional transformers available on all microphone inputs andon Group, Left/Right, Mono, and Matrix outputs.

• Full Bus assignment section on input and group sectionsallow for independent assignment to the Mono Clean Bus inaddition to the Stereo and sub group sections of the console.The Mono Clean Bus allows for any input or return signal tobe assigned to the Mono output without first having to passthrough a group.

• Dynamic Signal Present and multiple-sample-point peak indi-cator LED’s are used on all input sections of the console aswell as on all primary outputs.

• Mono/Stereo PFL and AFL system. When a stereo module isused, the signal is monitored in stereo while mono modules aremonitored in mono. Selected outputs may be monitored inmono or as stereo pairs.

• 8 Auxiliary Mix buses for use as effect and monitor sends.Aux Send circuitry has front panel Pre/Post fader switching.Pre fader signals have internal jumpers to select between a PreEQ or post EQ signal (Standard) source.

• Standard frame sizes include 24, 32, 40, 44 and 52 position,with a 64 position frame available on special order. Consolesmay be ordered as 4 subgroup (8 Module Positions usedincluding Master Section) or 8 subgroup (12 Module Positionsused including Master Section) versions.

• Any frame size may be ordered short loaded for later expan-sion.

• Direct access to Group Mix Bus allows expander mixers tobe easily patched into the console.

• Full facility return sections includes Gain Control to handle awide range of input levels, High and Low frequency EQ, AuxSends, full Bus assignment section and level, pan, PFL andMute controls.

• Mute system on input channels is designed to mute both pre-and post-fader signals including those Aux sends used as mon-itors. When muted, PFL circuitry, Peak and Dynamic SignalPresent LED indicators remain fully operational. This is a fea-ture not available on many consoles at any cost.

• External power supply with optional shared load parallelpower supply for uncompromised reliability.

• The EQ section includes an EQ IN switch with LED and a80Hz High Pass filter switch.

• Optional Matrix modules available.

• Optional Stereo Input modules available.

• Comprehensive Talkback section allows access to all primaryconsole outputs. Additional access provided to an externallocation such as an on-stage monitor mixer system. Externalsignals can also be assigned into the talkback system includingOscillator and Pink Noise source inputs.

• Left/Right summing switches to Aux 1-2 and Aux 3-4 allowfor simple setups of overdub mixes by allowing Left/Right sig-nals to be blended with Auxiliary mixes when used in record-ing applications. In contracting applications, this feature allowsthese Aux outputs to act as additional distribution amplifiersfor the Left/Right signals.

CENTURY SERIES

Century Series Console Power SupplyCentury Series Consoles use a separate rack-mountable power supply which provides the specific voltages used by each console.Crest Audio’ Century Series makes use of two different power supplies. The model and frame size of your particular consoledetermines which of the two supplies should be used. SP, TC, and GT consoles use power supplies as follows: Consoles withframe sizes of 24 or 32 modules use supply model XCVA04; consoles with frame sizes of 40, 44, 52, or 64 modules use supplymodel XCVA06.

Supply IdentificationThe type of power supply can be identified by the model num-ber shown on the back of the chassis and panel label..

Power RequirementsThe Century Series power supplies have certain electricalrequirements to operate properly. If possible the power supplyshould be connected to a dedicated circuit. Should any otherappliance on the same circuit draw enough current to overloadthe circuit, the breaker or fuse will trip causing loss of powerto the console. Note the maximum current draw specificationsat right. Be sure that the circuit to which you connect the sup-ply can handle the draw. The power switch on the supply front panel is also a circuitbreaker, there is no power fuse. Should the supply ever shutdown, or trip at start up, simply push the switch to the off posi-tion and then on again.

Ground LinkingSafety Considerations -Each new power supply is shipped with the AC third wireground connected to the console chassis ground. The connec-tion is made at the rear of the power supply unit. This is neces-sary for safety reasons so that exposed metal parts are ground-ed. In the event of a live conductor making contact with theconsole chassis or the power supply chassis then the currentwill flow to ground without a safety hazard arising. Note thatwhen the console is disconnected from the power supply thechassis ground connection to AC third wire ground is brokenand safety protection is lost. For uninterruptible grounding, ina fixed installation for example, make a connection directly tothe console chassis from the safety ground. Disconnect theground link on the rear of the power supply. This disconnectsconsole ground from power supply AC third wire groundwhich would otherwise create a hum-loop.

Twin Supply OperationWhen twin supplies are in use for automatic back-up, then theground links on both supplies should be fitted. In a situation where the safety ground to the console chassishas been connected and the ground path via the power supplyis causing a hum-loop, then disconnect the ground links onBOTH power supplies.

Console and Power Supply GroundingConsole chassis ground is electrically connected to audioground, pin 1 of XLR connectors and 1/4" sockets and to theterminal 'CONSOLE GROUND' at the rear of the power sup-ply. The AC third wire connection in the power supply cableconnects the metal chassis of the power supply to safetyground. This connection should never be disturbed. Hazardousvoltages exist inside the power supply which require the caseto be grounded. When rack-mounted, the power supply groundmay transfer to the rack case thru the front fixing screws,though this connection is not reliable. When a console is con-figured within a complete sound system the grounding require-ments may call for the ground link to be disconnected. This ispermissible only when an alternative ground path has beenprovided. If in doubt seek the advice of an experienced electri-cal engineer.

Power ConnectionsThe connections to and from the power supply vary dependingon your specific configuration. Before setting up the console,always check to make sure the AC voltage marked on thepower supply agrees with the local supply. Always connect theconsole to the power supply before switching on the powersupply. Do not run the power supply if it is not connected tothe console.

Multiple power supplies can be daisy-chained to provide fail-safe protection in the event of a supply failure. When two ormore supplies are used, both power supplies run all the time. Inthe event of supply failure, the remaining power supply(s) willtake over the entire load.

NOTE: Although both of the multi-pin connectors on the backof the power supply are labeled “POWER OUT”, it is neces-sary (and acceptable) to link two power supplies together asshown in the diagram below.

ADDITIONAL NOTE: The multi-conductor cable used forpower supply-to-power supply connection is different than thatused for a conventional power supply-to-console connection,and must be specified when the second power supply isordered.

SP Input ModuleThe SP input module is the most straightforward of theCentury Series. While it shares many features with morecomplex input modules, the SP input module is simple indesign and operation.

LINE SwitchSelects between the Balanced XLR Microphone Input con-nector and the Balanced Line Input 1/4" TRS connector.

48V Phantom Power SwitchTurns on 48V Phantom Power, required by certain micro-phones for proper operation.

PAD SwitchIntroduces a -15 dB attenuation to the mic input signal.

GAIN ControlAdjusts input gain for proper signal level.

80Hz High Pass SwitchReduces all low frequency content at a 12db per octave ratereferenced to 80Hz (-3db point).

Four Band Fixed EqualizerControls the cut or gain of four fixed frequencies (10 kHz,2.7kHz, 300Hz, 80Hz) within the input signal only when theEQ IN switch is depressed.

EQ IN SwitchInserts the EQ section into the input channel signal. An asso-ciated LED illuminates when the switch is down.

AUX Level 1•3 / 2•4Adjusts audio level of a mix for use as a monitor or an effectsend. The signal source for this mix may be selected pre orpost fader by an associated switch.

AUX ASSIGNMENT 3•4 SwitchSelects the first two Aux level controls between the Aux 1•3mix bus and the Aux 2•4 mix bus.

POST/PRE SwitchSelects the Aux 1•3 and Aux 2•4 signal sources between postand pre fader positions.

AUX 5 - 8 Individual Level ControlsAdjusts audio level of a mix for use as a monitor or an effectsend. The signal source for these mixes may be selected preor post fader by an associated switch.

PRE/POST SwitchSelects the Aux 5 through 8 signal sources between pre andpost fader positions.

PAN CONTROLPositions the channel image between the left (odd) and right(even) channel assignment.

MUTE Switch with LEDMutes the channel and all send functions. This switch doesnot affect the PFL switch or the Peak and Signal Present LEDindicators, The LED illuminates when the channel is mutedfrom the local mute switch.

MONO Bus Assign SwitchAssigns the post-fader input signal directly to the Mono Cleanbus.

Bus Assign Switches (L/R, 1-8)Assigns the post Pan Signals to the mix bus in odd/even pairs.Pan controls assignment between these two mix buses withextreme left pan assigning signal exclusively to the odd mixbus and extreme right pan assigning signal exclusively to theeven mix bus. When the pan is in its center position, signal isfed equally to the odd (left) and even (right) mix bus. Whenused in stereo applications, the channel signal may be locatedanywhere within the stereo image as controlled by the Pan con-trol.

PFL SwitchSamples the channel’s signal pre-fader and allows for monitor-ing within the master section of the console. This signal is notaffected by the Mute Switch. When depressed, the signal levelcan be seen on the Left/Right meters, and heard via the mixer’sheadphone or local monitor output. When this PFL Switch isdepressed, the channel PEAK LED indicator illuminates at alower intensity. When used as a status indicator of switch posi-tion, the Peak LED indicating circuit remains fully operationalby illuminating at a much higher intensity than its use as a PFLstatus indicator.

PEAK LED IndicatorIlluminates RED when any of the points monitored come with-in 3db of the clipping point. Signal is sampled after the inputpreamplifier stage, after the EQ section, and after the fader.

This LED also serves as a PFL ON indicator, but at a muchlower intensity than when it is used to indicate clipping.

SIGNAL PRESENT LEDConstantly displays level activity of the input channel by vary-ing in intensity.

100mm FaderUsed for control of all outputs of the channel except those Auxoutput sections selected by switch to a pre fader position. (TheInsert Output level is not affected by the fader position.)

GT Stereo Input ModuleThe GT Stereo Input Module is essentially two GT InputModules fit into one module space. This module is very use-ful for accepting remote feeds, effects inputs and other sig-nals that require stereo handling.

48V Phantom Power SwitchTurns on 48V Phantom Power for both L and R XLR inputs,required by certain microphones for proper operation.

LINE SwitchSelects between the Balanced XLR Microphone Input con-nector and the Balanced Line Input 1/4" TRS connector forboth L and R channels.

XLR PAD SwitchIntroduces a -20 dB drop to the mic input signal for both Land R XLR inputs.

L GAIN & R GAIN ControlsAdjusts input gain for proper signal level for both L and Rinputs.

80Hz High Pass SwitchFor both input channels, reduces all low frequency content ata 12db per octave rate referenced to 80Hz (-3db point).

Polarity Reverse SwitchFor both input channels, inverts the polarity of both themicrophone and line inputs. An internal jumper selectsbetween Left channel only or both Left & Right channels.

Three-Band Equalizer ControlsThe equalization controls in this module act upon both L andR stereo channels at once. The upper band is a fixed shelvingEQ with one control knob. The middle and low frequency EQbands are set up as sweep EQ’s: the lower knob controls thegain or cut as in the fixed EQ; while the upper knob controlsthe center frequency adjusted by the inner knob. These centerfrequencies are printed on the chassis around the upper knob.

EQ IN SwitchInserts the EQ section into both L and R input channel sig-nals at once. An associated LED illuminates when the switchis down.

AUX Level 1•3 / 2•4Adjusts audio level of a mix for use as a monitor or an effectsend. The signal source for this mix may be selected pre orpost fader by an associated switch. The left channel is sent tothe odd Auxes, and the right channel is sent to the evenAuxes.


STEREO SwitchAUX 5-8 Individual Level Controls normally send a summed(L+R) signal to the AUX outputs. When the STEREO switchis depressed, AUX 5 and 6 become a ‘right’ send and ‘left’send respectively. This can be used for a stereo effects send.

AUX 5 - 8 Individual Level ControlsAdjusts audio level of a mix for use as a monitor or an effectsend. The signal source for these mixes may be selected pre orpost fader by an associated switch.

WID(TH) ControlWhen used together with the BAL control, the WID controlprovides a unique way to configure stereo panning. Whenturned all the way counter-clockwise, this control convention-ally assigns the left signal to the left (odd) channel assignment,and the right signal to the right (even) channel assignment.When adjusted to the ‘twelve o’clock’ position, left and rightsignals are panned straight up the middle, effectively summingthem to mono. When this knob is turned all the way clockwise,the left and right signals are ‘flip-flopped’, left being assignedto the right (even) side, and the right side being assigned to theleft (odd) side.

BAL ControlPositions the entire channel image between the left (odd) andright (even) channel assignment. Together with the WID con-trol, this gives total control of the stereo image.

Matrix ModuleThe Matrix Module allows the creation of an independent mixusing the Main outputs (and an External Input) as signalsources.

Matrix AUX IN ControlsControls level of external balanced input signals.

L & R MAINS ControlsControls level of post fader L & R signals from main section.

MONO MAINS ControlControls the level of post fader Mono signal from main sec-tion.

STR PGM IN ControlControls level of Stereo Program being input into the matrix.(These switches do not function on the SP/TC Consoles)

LEFT/MONO/RIGHT SwitchesSelects which main section signals are introduced into thematrix. (These switches do not function on the SP/TCConsoles)

GROUPS 1-4 ControlsAdjusts the level of Group signals 1-4 introduced into thematrix.

GROUPS 5-8 ControlsAdjusts the level of Group signals 5-8 introduced into thematrix.

MUTE Switch with LEDMutes the output. This switch does not affect the PFL switchor the Peak and Signal Present LED indicators.

TB ENABLE ControlInjects the talkback signal from the Master section into thematrix.

PFL SwitchSamples the matrix signal pre-fader and allows for monitoringwithin the master section of the console. This signal is notaffected by the Mute Switch. When depressed, the signal levelcan be seen on the Left/Right meters, and heard via the mixer’sheadphone or local monitor output. When this PFL Switch isdepressed, the PEAK LED illuminates at a lower intensity.When used as a status indicator of switch position, the PeakLED indicating circuit remains fully operational by illuminat-ing at a much higher intensity than its use as a PFL status indi-cator.

PEAK LED IndicatorIlluminates RED when any of the points monitored come with-in 3db of the clipping point. Signal is sampled after the inputpreamplifier stage and after the fader.


SIGNAL PRESENT LEDConstantly displays level activity of the matrix by varying inintensity.

100mm FaderUsed for control of all outputs of the channel. (The Insert out-put level is not affected by the fader position.)

Rear ConnectionsMatrix OutThis connector delivers a balanced signalfrom the matrix module.

Matrix InsertThis jack allows for the insertion of an effector signal processor into the audio path of thematrix output.

Aux In 1This connector accepts a balanced signal at+4dB level, and then sums it with all the othersignals in the matrix output.

Aux In 2This connector accepts a balanced signal at+4dB level, and then sums it with all the othersignals in the matrix output.

Console DisassemblyThough you shouldn’t have to disassemble the console, it is necessary to remove modules to change the jumper and switch set-tings associated with the internally selectable options. The following steps detail the tasks involved when taking the consoleapart.

ONE • Open the armrestTo properly remove one or many modules, the black paintedarmrest must first be opened. To do this, the two thumb-screws (see diagram at right) must be loosened from below.Once these screws are loose, slide both of them a few inches tothe side (they will only move in one direction). Once thescrews have been moved the armrest will easily roll backexposing the module screws beneath.

TWO • Remove top module screwOnce the armrest has been opened, there will be a single screwholding each module in place. Remove the screw from themodule(s) you want to remove.

THREE • Remove rear screwsOn the back panel of the console there are two screws holdingeach module in place (see diagram at right) Remove bothscrews from each module you wish to remove.

FOUR • Lift the module(s) outAs you lift the module out of the chassis three wires must bedetached before the module can be completely removed: 2flat-wires (ribbon cables) and one ground wire.

The flat-wires are removed by flipping the latches on the endsof the connectors. Once the tabs have been flipped the connec-tor should pull off easily.

The ground wire (green) is a spade lug which pulls off.

FIVE • Putting it all back togetherRe-assembling a Century Console is as easy as taking it apart, but only if you know where everything goes. If you are going tobe removing a number of modules, consider replacing the first before removing the second. Reversing the above steps shouldresult in the console being as well put together as it was when it left the factory.

SP / TC / GTCENTURY SERIES

GLOSSARYThe following glossary explains the features and functionsfound on Century Series front of house consoles.

80Hz High Pass SwitchWhen depressed, this switch attenuates all low frequency con-tent at a 12db per octave rate referenced to 80Hz. This controlis useful with live microphones, as it helps reduce undesirablelow frequency "rumble", usually is transmitted to the micro-phone by way of its microphone stand. High quality micro-phones employ internal shock mounts which lessen this prob-lem, but it still remains to some degree. If this material is notremoved, the low frequency content tends to make the amplifi-er and speaker systems work harder.

100mm Fader See Fader48 Volt Phantom PowerThis switch turns on the +48V used to power some micro-phones. See XLR Microphone Input for more information.

Auxiliary 3•4 SwitchThis switch toggles the two upper Aux Send controls between1,2 and 3,4. With the switch up, the two Send controls feedAux 1 and 2. With the switch down, the two controls feed Aux3 and 4.

Auxiliary 8 Direct SwitchThis switch disconnects the Aux 8 level control from the Aux8 mix bus and instead is used to control the Direct Output ofthe channel. Normally the Direct Out jack is post-fader. Whenthe Aux 8 Direct switch is depressed the Aux 8 level controlassumes output control of the direct out signal. The Aux 8 con-trol is fed pre-fader.

Auxiliary BusThe Aux Bus carries signal from the Aux Send controls to theAux outputs on the rear panel of the Master Section. A typicalsetup would entail using the Aux 1-4 sends for monitor mixeswhile Aux 5-8 are used for effect sends. If a separate monitormixer were being used, Auxes 1-4 could be used for additionaleffect sends. Effects can be returned via the EFX Return sec-tion of the group modules or through spare input modules.

Auxiliary Mute SwitchesThe Master Section of the GT consoles have mute switches foreach Aux send. When depressed, this switch mutes the corre-sponding Aux Send Master. When the mute is engaged no sig-nal leaves the associated Aux out jack and a red LED illumi-nates to the left of the switch. These mute switches are activeonly if the Aux Mute Master switch on the Master Module isdepressed.

Auxiliary Pre/Post SwitchSee Pre/Post Fader Switches

Auxiliary Send ControlsAll Century Series consoles employ eight Aux Sends per inputchannel which send signal to the Aux Bus. These sends arecontrolled via the six level controls on each input module. AuxSends 1-4 (orange) are typically used for monitor sends. Theseare the two switchable Auxes; see AUXILIARY 3•4 SWITCHfor more info on toggling between 1,2 and 3,4. Aux Sends 5-8

(green) are typically used for effect sends. Each effect returnsection has Aux 1-4 Send controls, which could be used foradding effect return signal to the monitor mix. Internal jumpersselect between pre/post EQ.

Bus Assignment SwitchesWherever these switches occur, they assign the post Pan potsignals to odd and even mix buses. The Pan pot controlsassignment between odd and even mix buses with extreme leftassigning signal exclusively to the odd mix bus and extremeright the even mix bus. It is a common practice to assign alleffect return channels to a sub group channel. This enables theoverall amount of effect signal to be controlled from a singlefader location. Between musical numbers, it is possible to turnoff the effects with this group fader or group mute switch or tovary the amount of overall effect return in reference to the dryoriginal signals, using the group fader control.

DC Power IndicatorsEach Century Series console uses a variety of electrical volt-ages which are fed to the console from the power supply. Thestatus of each operating voltage (+20, -20, +48, +24) is indicat-ed by four LED’s on the master module. If the console everbehaves abnormally, first check these LED’s to make sure thatthe power supply is providing the proper voltages.

Dim SwitchThis GT Master Section switch produces a -12dB attenuationin signal to the local monitor. This feature is useful for tempo-rary lowering of local monitor levels without actually adjustingany pots or faders. (Local monitors are automatically dimmedwhen Talkback button is pressed.)

Direct Out JackEach input module has an unbalanced 1/4 direct out jack. Theoutput from this jack is post-fader unless the AUXILIARY 8DIRECT switch is depressed. When this switch is down theoutput is controlled by the Aux 8 pot. See AUXILIARY 8DIRECT for more information on that switch.

Effect Auxiliary Level ControlSee AUXILIARY SEND CONTROL

Effect Return EQEach effect return section has a two-band fixed EQ. TheseHigh and Low frequency controls are centered at 10kHz and80Hz respectively.

Effect Return GainThis control adjusts the gain on the signal returning from theeffect. Use the effect return signal present and peak LED’s toset the gain properly.

Effect Return Subgroup AssignmentsMuch like the switches on each input module, these switchesassign the corresponding effect return to any or all subgroups.The Pan control operates in the same fashion, that is; extremeleft assigning signal exclusively to the odd mix bus andextreme right the even mix bus.

EQ In SwitchThis input module switch, when depressed, inserts the EQ sec-tion into the signal path and illuminates a green LED to the left

CENTURY SERIES

of the switch. With the switch in the up position, the input sig-nal bypasses the EQ section and continues unmodified.

EQ SectionsThese controls are used to modify the tonal quality of an audiosignal. All Century Series consoles have a four-band EQ sec-tion on each input module. The effect return sections, withinthe group modules, have two-band EQ sections. Within aninput module, the EQ section will affect the signal only if theEQ IN button is depressed.

EQ Control knobs - Fixed EQ:When there is only one knob, it controls the boost or cut of afixed frequency range. The SP input modules and all effectreturn sections have these single knob/fixed EQ controls.

EQ Control knobs - Sweep EQ:When there are two knobs, the inner knob controls the boost orcut as in the fixed EQ, while the outer knob controls the centerfrequency adjusted by the inner knob. These center frequenciesare printed on the module around the outer knob. The GT inputmodule has the frequency sweep knobs on all four bands,while the TC input module has them only on the mid-frequen-cies.

EQ Sweep ControlSee EQ SECTIONS

External Talkback Input SwitchThis switch disconnects the two regular talkback microphoneinputs and switches on the external talkback input XLR foundon the rear panel of the GT master section.

External Talkback Output SwitchThis switch activates the external talkback output XLR. Thesignal fed to the connector is the same signal being sent to thetalkback assignments.

FaderThe fader is used for primary level control of the channel,except those Aux output sections selected to a pre-fader posi-tion. (The Insert output level is not affected by the fader posi-tion.)

Optimum noise performance is achieved when the fader isoperated near the 0 fader position and all gain controls areproperly set. This does not mean that all channels should be setat 0 . Proper mixing requires varying of at least some of thefaders. The 0 point should be considered a reference, with allvolume changes taking place between the -10 and 0 referencepoints at normal desired levels. For effect, faders may be oper-ated below this level, provided no faders within the group ormaster section are increased in level to compensate for theinput’s lower fader setting.

Fader Reverse SwitchThis switch swaps roles between the Effect Return Level potand the Subgroup Fader. When depressed, this switch causesthe Effect Return Level to be controlled by the Subgroup fader,and the Subgroup level to be controlled by the Effect ReturnLevel pot. If you want the control of the fader when settingeffect returns, this switch is particularly helpful. A red LEDindicator is provided to the left of the switch and illuminatedwhen the switch is depressed (reverse mode).

Gain ControlThis knob adjusts input gain circuitry for proper electricaloperation. Adjust this control by monitoring signal present(green) LED for bright intensity, with peak (red) LED flashingonly occasionally when the loudest program material is pre-sent. When a PFL switch is depressed on an input channel, thissignal can be observed on the Left/Right monitor meters withinmaster module. When using this method for adjustment of theGain Control, normal signal level should be adjusted to show alevel between -9 VU and 0 VU. Constant distortion on an inputchannel could mean that the input channel is being overdriven.Check for improper input gain adjustment first.

Group AssignmentsSee BUS ASSIGNMENT SWITCHES

Group MeterLocated at the top of each subgroup module, this ten-segmentLED meter monitors the post-fader output of the group.Similar meters on the Master Section monitor Left and Rightoutputs.

Group XLR SwitchThis switch assigns the post fader group signal to the group outXLR located on the rear panel of the group module.

Headphone JacksLocated at the top of the master section and under the rightside of the hand rest, these jacks provide a pre-fader stereoheadphone level output of the Left and Right outputs. Whenanything on the console is PFL’d or AFL‘d, the R+L output isreplaced by whatever is PFL’d/AFL‘d.

Headphone Level ControlThis control adjusts the level of the signal fed to the two head-phone jacks; located in the upper right portion of the mastersection, just below arm rest on the far right side.

HF Peak/Shelve SwitchThis switch is used for switching the high frequency EQ con-trol between the normal shelving setting to a peak setting.

High Pass SwitchSee 80Hz HIGH PASS SWITCH

HMF EQ ControlSee EQ SECTIONS

Insert JackThis jack allows you to access a point in the channel’s electri-cal circuit for inserting an external signal processor. The outputlevel of this connector is designed to drive the inputs of mostexternal signal processing equipment and to accept the result-ing output signal. When a properly wired TRS plug is insertedin this jack, the input signal path is broken after the gain stageand high pass filter. The return signal is fed to a point justbefore the EQ section. See the Connections and Conventionssection in the front of the manual for specific information onplug polarity and signal assignments. (This jack could be usedto connect an effect with an unbalanced 1/4" connector; how-ever, the signal path would be broken, leaving the remainder ofthe input module unused, and the effected signal would need tobe returned to the console via an unused input channel. A

stereo (TRS) plug can be used with the Tip & Ring tied togeth-er to access the channel signal pre-EQ).

Internal OscillatorThe GT master section has a 1 kHz internal oscillator. Thisoscillator can be used as signal source to run tests, diagnosticsor calibrations. The oscillator can be assigned to all Groups,Auxes and Matrices via the Talkback assignment switches.

Lamp Dim ControlThis control adjusts the brightness of whatever lighting devicesare plugged into the XLR sockets on the light bar.

Left MeterThis ten segment LED meter normally displays the signal levelof the Left output. If any signal is in PFL mode, then this meterdisplays that signal instead.

LF Peak/Shelve SwitchThis switch is used for switching the low frequency EQ controlbetween the normal shelving setting to a peak setting.

Line Input JackThis is a balanced, high impedance input which is designed toaccept both balanced and unbalanced line level inputs. Toselect this input source, press the front panel LINE switch. Seethe Connections and Conventions section in the front of themanual for specific information on plug polarity and signalassignments.

Line SwitchThis switch, when depressed, selects the balanced Line Inputas opposed to the default balanced XLR Mic input.

Local Monitor Level ControlThis control adjusts the level of the signal to the Local MonitorOutputs on the back of the Master Section.

Matrix Level ControlThese controls adjust the amount of group, L/R or Mono signalfed to the respective matrix.

Matrix Master ControlThese controls adjust the final signal level for the associatedmatrix output.

Matrix Pre/Post SwitchThis switch switches the group, L/R or Mono matrix sendbetween pre and post fader.

Mono Bus Assign SwitchAssigns the input signal directly to the Mono Clean bus. Thissignal is unaffected by the position of the Pan Control, but iscontrolled by the level position of the fader. Signal may beassigned to this bus when you wish to assign this input signalto the Mono output without going through the Stereo section ofthe mixer. In addition to the many mono output uses, this out-put can be used as an additional Effect Send.

Mute SwitchTurns off all send functions (except insert send) of the moduleincluding those being used as monitors. (Monitor Mute may bedefeated internally - See your service facility for further infor-mation.) This switch does not affect the PFL switch or thePeak and Signal Present LED indicators, enabling monitoring

of input channel activity regardless of mute switch position.The LED illuminates when the channel is muted, either fromthe local mute switch or from any activated mute group.

SwitchSee POLARITY REVERSE SWITCH

PAD SwitchThis -15dB pad attenuates the signal presented to the first stageof the input module. It is important to note that the Pad Switchacts only upon the balanced XLR input signal; it has no effectupon the 1/4" input signal.The input GAIN control should bepositioned somewhere within its center 80% of travel. In theevent that the Gain control is set in its lower 10% of travel, andthe Peak LED is indicating more than an occasional short illu-mination, the PAD Switch should be depressed and the Gainre-adjusted as above. In the case where the GAIN control is setto its upper range of travel (3 o’clock position or above) withthe PAD switch depressed, the Gain Control should initially belowered and the PAD switch released. The gain should then beincreased and adjusted as above.

Pan ControlWhen operating a stereo sound system or recording, this con-trol positions the image anywhere within the stereo spectrumwhen the Left/Right assignment switch is depressed. Whensignal is being sent to a subgroup, the pan control acts as partof the assignment system. Full counter clockwise assigns sig-nal to the odd numbered mix bus and full clockwise assigns thesignal to the even numbered mix bus. Subgroups may also beused as stereo pairs in which case this control functions thesame as when assigned to the Left/Right bus.

When the pan is in its center position, signal is fed equally tothe odd (left) and even (right) mix buses. When used in stereoapplications, the channel signal may be located anywhere with-in the stereo image as controlled by the Pan control.

PEAK LED IndicatorIlluminates RED when any of the points monitored come with-in 3db of its clipping point. Occasional quick blinking of thisLED is normal under proper operation; when this LED illumi-nates noticeably, a correction should be made in the level con-trol feeding that position to a point where this illumination isreduced to the normal occasional flashing. It should be notedthat certain musical instruments produce very high levels ofpeak response that are far above the average output levels ofthese instruments. These include portions of any drum kit, butmost notably the bass drum and snare drum. It is consideredalmost normal practice on these instruments to set the inputgain control to a point when the Red Peak LED is just firingwith nearly every hit of the drum.

This LED also serves as a PFL ON indicator, but at a muchlower intensity than when it is used to indicate a near overloadcondition.

PFL SwitchThe PFL (Pre Fader Listen) switch enables the operator to lis-ten to the channel signal before the fader or main channel levelcontrol, allowing for monitoring within the master section ofthe console. This signal IS NOT affected by the Channel MuteSwitch. When this switch is depressed, the signal level can be

seen on the Left/Right/Monitor meters, and can be heard bothin the mixer’s headphone output and on the rear panel monitoroutput of the console. When the PFL Switch is depressed, thechannel PEAK LED indicator illuminates at a low intensity.When used as an indicator of switch position, the Peak LEDindicating circuit remains fully operational by illuminating at amuch higher intensity than its use as a status indicator.

Phantom PowerSee 48V PHANTOM POWER

Polarity Reverse SwitchThis switch is used on input channels to adjust between dissim-ilar microphone output polarity (see your microphone’sinstruction manual). It is also used to adjust phase cancellationbetween microphones when more than one microphone is pick-ing up the same acoustical signal (This should be kept to aminimum with proper microphone placement).

Pre/Post Fader SwitchSwitches the Aux signal sources between pre-fader and post-fader positions. The pre-fader position is usually used for mon-itor sends, so that any movement of fader level does not affectthese outputs. This is desirable for monitors, since their levelsnormally need to be operated independently of the main (front-of-house) system. When in the post-fader position, signal out-put level from the Aux sends will proportionally follow themain signal level. The result is maintenance of an effect in pro-portion to the main signal level. When an input signal is fadedto 0dB, the post-fader Aux Send signals are also decreased to0dB. In some cases, it may be desirable to derive effect sendspre-fader for special effects, such as those generated by a vocaldoubler or harmonizer. The choice of switch position should bedetermined by the actual situation; though as a general rule,choose the pre-fader position for monitor sends and post-faderposition for effect sends.

Right MeterThis ten segment LED meter normally displays the signal levelof the Right output. If any signal is in PFL or AFL mode, thenthis meter displays that signal instead.

Scene Mute Assignment SwitchFound on GT input and group modules, these switches assignthe input or EFX Return signal to one or more of the scenemutes. These mutes are activated via the scene mute masterswitches found on the master section.

Scene Mute Master SwitchesFound on the GT Master Section, these switches activate thefour scene mutes.

Scene Mute Safe Switch w/LEDThis switch, found beneath the Scene Mute AssignmentSwitches, disables any selected scene mutes. A green LEDindicates that the Safe switch has been engaged.

Signal Present LEDThis LED displays, in real time, the level activity of the chan-nel by varying the intensity. Any illumination of this LEDindicates that a signal is present and is somewhere within theusable operating level. Optimum operation is when this LED isat a bright but varying intensity and following the channel’s

signal levels, with just an occasional short flash of the red peakLED indicator.

Sweep Control See EQ SECTIONS

Talkback Assignment SwitchesThese switches assign the talkback signal to the outputs and/orauxes.

Talkback Level ControlThis knob controls the final level of the talkback signal, anddims local monitor output, if Dim switch has not been pressed.

Talkback Microphone InputFound on the master section (GT) and under the arm rest onthe right side, these balanced XLR inputs allow for a micro-phone or other balanced mic-level source to be connected tothe talkback system.

Talkback On SwitchThis switch activates the entire talkback system including theinternal oscillator.

XLR Balanced OutputsThis output is designed to drive both balanced and unbalancedinput devices without adaptation. Signals are normally bal-anced on this output connector. The output is designed so thatif either pin 2 or pin 3 were intentionally shorted (as in con-necting to an unbalanced input of your next stage of electron-ics) or accidentally shorted, the output level of the non-shortedconnector pin increases by 6db. This is an amount equal to thenormal loss of a balanced output when one pin of a balancedoutput is shorted. The result is no need for external gain makeup.

XLR Microphone Input ConnectorBalanced XLR Input is designed to receive professional LowImpedance microphone signals. The input Gain controls on thefront panel adjusts for most input levels. In the event of exces-sive input levels, the front panel input pad switch should bedepressed. Front panel selection of 48 Volt Phantom powerenables most types of condenser microphones that require suchpower to be used. (Note: most input devices can tolerate 48Volt phantom power to be placed on their output terminals(provided they are truly balanced) without causing damage tothe device. See your device’s operating manual for correctoperation. (If in doubt as to whether your non-condensermicrophone may be damaged by using Phantom Power, pleasemake sure that the front panel phantom power switch on thatinput channel is in the off [out] position.)

This input may also be used for low level line input signals,provided the source (instrument) is able to drive a 5k Ohm orhigher load. (See your instruments or electronics owner’s man-ual for output impedance.) When line output devices such astape players are plugged into the microphone input, specialcare should be observed that the phantom power is turned offon that channel, as damage may result. Because of this, it isrecommended that the 1/4" line input connector be used whenconnecting a line level device. 48 Volt Phantom power is notpresent on these input connectors, and the impedance of theline input connector is high enough to accept any line leveldevice.
