AXIOhI soundreinforcement Console The D&R Axion series is a balanced 8 buss Ftont Of House (FOH) soundreinforcementmixing console designed to take the central rcle in a life performance facility. The Axion is completely modular and can be configured to precisely zuit your pafiicular system requirements. To become completely familiar with your Axion and gain the maximum benefit from its use, \ile recornmend that you tead this manual thoroughly.
THE CHASSISSYSTEM 1.0 The ChassisSystem The Axion is available in two frarne sizesoaccepting44 and 60 input rnodules.The basic frarne includes five blank rnodules,two are located on the extrerne left and right of the frarne and two rnore are on the left and right of the master sectior, and there is one rnore right frorn the group rnafrix rnodules.
THE MASTER MOI}ULES The Axion has six rnasterrnodules which are cornpletely modular. A11inputs and outputs are located on the back of the rneter bridge. The paruEraphsbelow gtve a description of eachrnodule sectiorl. 2.1 Solo section The Solo section has a master PFL volume corrtrol with a center detent fot nominal levels and a master AFL volume control with a cenhe detent and a Channel to Solo In Place switch with a switchcover to prevent fiom accidental switching dwing life performanoes.
The monitor control has a sepetateoutput for nearfield monitoring. The Phones control has its own outputs on the frontpanel in a t'ecessedsection close to the faders. A mute switch cuts the very powerfull headphonesamps. The main stereo faders afe mono audiotapr faders and control the overall outgoing level coming from the main stereo mix bussamps. A 10 dB gain is available at the output which is set to be +4dBu nominal. Monitor level The Monitot level controls the total outgoing level to the monitot.
Communications to phones This switch brings the cornrmrrication systern into the phones to be able to listen to stageengtneerscalling you through their "beltpacks" Phonesto communications This switch allows you to pass the rnonitor signal to the beltpacks. Stage englneers can pre fade listen to channels and have the sarne acces to all relevant signal irnloutputs in the console as the rnain balance engrneef.
2.4 RECORI) OUT / AUr P.A. This section provides you with a second stereo output from the Axion's nlaster section. It can be fed frorn the either the stero output or the rnono output. Both these srgnals can be taken pre or post the rnain faders. Arl AIIL switch checks out the signal strength and sorrcing. 2.5TWOTRACKREPLAY. The Axion has a seperatetwo track replay input with lineair fader and a two band equalizet.
NOTE: THE MIDI SOFTWARE IS NOT YET IMPLEMENTED, BUTWILL BE SOON BY A *ROM''UPDATE. The CHANNELPATCH switch letsyou changethe display frorn showing the rnidichannel nurnbers into showing the patch nurnbers used for storing rnute patches. The display seffes different rnodeswhich will be explained later. The STORE switch lets you store mute settingsfrorn the channels against a patch number. The UP/DOWN switches let you step up and down through the 64 available patchnurnbere.
2.8 AUXILLIARY MASTER SECTIOhI All auxilliary rnastersections areidentical in function. All sections have level corrtrol, a talkback enable switch, an AFL switch, a Mute switch and a globul pr*lpost switch. Each Aux rnastercontrols the bussesfrorn the channels. The solo switch sendsthe aux buss signal to the rnonitors which is a post-fader signal. The associatedLED lights indicating the activated solo switch.
THEII\PUT MOI}ULE 3.0 THE INPUT MODULE DESCRIPTION The Axion input module is a basic input design whereby all signal flow takes place ftom the micmphone to the main outputs. Each input channel is shipped with a 25 segment LED bargraph meter which is a peak teading device with attack and rclease times in conformance with world standards. It reads the level atfour points in the channel. At the pre insert point, at the post insert point, at the post EQ point, and at the post VCA point.
Line switches the microphone input to line input on the channel. The line input has its own balanced input amp and is corrtrolled by the active (dual) gain contnol. The GAIN control is the single most important conttol on the console. With this corrtrol accumtely set, it is possible to achieve the very best signal to noise tatio and maximum headroom tequired for high quahty life sound. This conmol is for adjusting the line / mic input and has seperateelectronics although only one lcrob adjusts the dual pot.
The LMF (Low / I\fid Fteq.) section has level and ftequency controls and is also a constant Q type, therefore the bandwidth sefting willmarch that of the level control. The frequency ranges from 50 Hz to 1000 Hz and has a maximurn boost or cut of 16 dB. The bandwidth is switchable between Il3 md 2 octaves. All level controls are center detentedmaking neutral pmitions easy to establish.
The peak led in the channelrnodulernonitors signal level on 4 points in the channel. The MUTE ry"tern is a special soft-muting systerncontrolled either by the local rnute switch or by the rnute cornputer located in the master section. Low intensity rnuting will indicate that the rnute function can be controlled by the rnute cornputer. The SAI1E switch prevents the rnute being controlled by the rnute computer. 3.
The ground cornpensatedinsert send The balancedinsert return The balanceddirect output On the rnain printed circuit board there is a provision for morrnting a rnic input transforrnet allowing for ground separatiotr. Note: The default setting on the direct output is +4 dBu. A setting of - 10 dBV can be chosen on the channel boards using jurnpers. Arry level between -80d8 and +6 dBu is adjustableon the direct output. A provision is rnade for inserting transformenson the line and group outputs.
THE STEREOMOI}ULE 4.0 THE STEREOMODULE I}ESCRIPTION This stereornodule is in most ways a copy of the channel input rnodule with the exception of sorneextra iterns such as an irnage control and a ptelpost solo systern. 4,I CHAhINEL ASSIGNSECTION The left and right signals frorn the balance control can be assigned in pairs to the groups and to the Left/Right buses.The assigrnentto the rnono bus is a surnrnedleft/right signal pffit VCA. 4.
Each band has a boost or cut of 16d8. The whole equalizeris switchable in or out the circuit. 4.5 AUX SEIYDSECTION The Aux send section has dual concenftic pots to feed Aux busses t&2 and 3&4 which is used for feeding stereo effects. Aux sends L&2 and3&4 are globally pre / post switchable in the master section. The mono switch related to Aux 1-4 has the following functions. In the up position the left input signal will feed aux 1/3 and the dght input signal will feed u,tx2l4.
4.7 Fader VCA section The Axion has a high quality 100rnrnALPS fader, P&G fadensare optionully available. The lineair fader controls the high quality dbx VCA's which in turn can be controlled by u group rnasterfaderoif the channel is assignedto such a fader. Assignrnent of the channel VCA fader is as follows. By hitting the VCA select switch once, one of the led indicators 18 will light, indicating which VCA rnasteris selected.By hitting the VCA relect again the next in number VCA will be selected.
The eight group outputs can be rnixed individually in the rnatrix. These group outputs can be sent pte or post the group fader into the matrix. The overall level of the rnafrix signal is controlled by u short tmvel lineair fader. *talkback A enable" switch deblocks an already selected "talkback to rnatrix" routing in the colnrnunications rnodule. NOTE: The talkback srgnal is not changed by rnute and I or fader settings in the Matrix output! The PFL and MUTE switches speak for thernselves. 5.
6.0 INSTRUCTIONS FOR OPERATION The AXION is designed to be the perfect answer for life sound reinforcement. In order to get more familiar with the Axion, we shall discuss the entire sound prlccess. LITE This is the beginning of a session.All input channels are placed in the mike mode by leaving the line switch in the up position if the microphone input is to be used in this channel. Phantom powedng is applied if necessary. The EQ switch should be in the up position unless you requirc EQ on that mike.
switch which will step thrcugh all vcamasterassign leds. If you have assigned yout charrnel to the group VCA, the group mastet VCA will control the channel VCA frrcm now on. The audio will still be ptocessedthrough the audio summing amps. This could be the mono, stereo and or audio gtoups. Insert Channel / Group For high dynamic fange types of inputs, a signal processot such as a complessor / limiter can be inserted in the channel or in the group insertif an entire group signal needs to be ptocessed.
You colnrnunicateby hittmg the *COMM" switch rnornentary in its "down" position or pefinanently in its "up" positiorl. The stageengineer tells you for instarrcethat he has to changernikes and you tell hirn which channel he has to plug in the rnic. Now you hit *PHONES to COMM". in the corffnunications rnodule and solo the rnentioned channel to listen what's going on in that specific channel.
Yout local elechic power corry)any will ptovide you with all local electrical codes and safety regulations. Thete afe solne grcunding rules to follow. All signals in a life sormd situation are rcfercnced to gtound. This grormd must be clean and ftee of noise. A central point should be selectedas the main grounding point and all grounds should originate from this point. This is commonly referted to as a *staf ground system". In some instances electtical conftactots will daiqy chain grolmd corurections.
the Monitor control cloclavise until it is wide open while listening for excessivenoise. You should only hear a faint "hiss". If everything is O.K., continue. If any hurn or excessnoise is present,stop and fiy different ground and shielding affangements until the system is clean. NOTE: MAKE SURB THAT YOU CHECKFORHUMOR NOISE AS EACH INPUT OR OUTPUT IS CONNECTED. 8.3 SHIELI}ING Ah[I} GROT]NI}ING OF AUI}IOEQUIPMENT The shield of any audio cable connection should be connected at one end only.
It is irnportant to understand the terrn balanced. Elalanced does not rnean the input or output is professional, the single factor that norrnally deterrnines whether sornething is professional is the level of the input or the output. +4 dBu is considered professional. -10 dBv i s c onsidered serni -professi onal . Elecause rnany serni-professi onal tape rnachines afe built to professional specifications, D&R builds into the Axion console the ability to interface with both levels. 8.5.
On the connector pcb's there are Molex 3pin locking connectors to be used to wire rnultipin connectors to sorne or all of the irrloutputs. There ate also 4 pin headers to interface with optional trarrsforrners for the Line and Direct output. The optional mic transforrner should be placed on the rnain pinted circuit board. 8.7JUMPER SETTINGS ON THE CIIAhINEL The following changesin srgnal flow could be rnadeby jurnp"r settings on the printed circuit channel boards.

NOTE: It is advisable to cut the shield at the master consoleside! As soon as two or rnore consolesare linked the solo systern is active on all consoles.
Suppott Departrnent for advice. If the problern cannot be corrected over the phone, D&R will despatch a replacenrent rnodule (ground freight prepaid) the same day. Most problerns can be forHrd using logical thinking and sirnply replacing socketed integrated circuits. LO.LRemoving a Module The Axion is a complex piece of equipment and some understa:ndingof its internal layout is necessarybefore removing a rnodule. An input module has wiring to the master section and backplates and the stargtound wire.
