INTRODUCTION
The AX2010A Ver cal Line Array element is designed for a wide range of sound reinforcement applica ons where a fl exible and easy to use ver cal array systems is needed. The AX2010A has been designed both for rental live sound applica ons and for fi xed installa ons and has been engineered
for the simplest use possible but without sacrifi cing anything in sound quality and performance. The high frequency range is reproduced by two low-distortion compression drivers, equipped with very light-weight diaphragms. Two transmission line waveforming waveguides have been used to load the HF drivers, in order to provide a detailed and natural sound and to achieve a long-distance HF projec ng capacity. The two 10” woofers employed in the reproduc on of the mid-bass range are equipped with very light-weight cones. The lightness of the diaphragm is furthermore improved by the use of aluminium voice
coil instead of conven onal copper. This ensure a fast reproduc on of the mid range and of mid-bass musical passages, improving also the thermal capacity of the voice coil and, consequently, controlling the overall power compression. The two 10” woofers are back loaded by a short hybrid transmission line that minimizes the eff ect of the box resonances and eliminates the “boxy” mid-bass sound commonly obtained from regular bassrefl ex enclosures. The crossover fi lter approach is based on a “Constant Power” technique. Thanks to a par cular phase combina on between the two ways around the crossover frequency, this approach is able to provide a very stable horizontal coverage and a very stable off -axys sound image, also minimizing unwanted eff ects around the crossover frequency. The further applica on of phase lineariza on techniques, combined to constant power crossover, yield a linear phase response and a coherent  me response. This allows for a natural percep on of acous c instruments and voices and for an improved depth of the sound image.

POWER PANEL
MAINS IN - Powercon® NAC3FCA power input connector (blue). To switch the
amplifi er on, insert the Powercon® connector and turn it clockwise into the ON posi on. To switch the amplifi er off , pull back the switch on the connector and turn it counter-clockwise into the POWER OFF posi on.
WARNING! In the case of product failure or fuse replacement, disconnect the unit completely from the mains power. The power cable must only be connected to a socket corresponding to the specifi caƟ ons indicated on the amplifi er unit. The power supply must be protected by a suitably rated thermo-magneƟ c breaker. Preferably use a suitable switch to power on the whole audio system leaving the Powercon® always connected to each speaker, this simple trick extend the life of the Powercon® connectors.
POWER OUT - Powercon® NAC3FCB power output connector (grey). This is connected in parallel with the MAINS ~ / IN. The maximum load
applicable depends on the mains voltage. With 230V~ we suggest to link a maximum of 4 AX2010A loudspeakers, with 120V~ we suggest to link a maximum of 2 AX2010A loudspeaker.
CONTROL PANEL
ON - This LED indicates power on
status. PROT - This red LED lights when the amplifi er module is in protect mode for an internal fault and, consequently, the amplifier is muted. SIGN LIMIT - This LED lights in green to indicate the presence of the signal and lights in red when an internal limiter reduces the input level. INPUT - Audio signal input with locking XLR connector. It has a fully electronically balanced circuitry including AD conversion for the best S/N ra o and input headroom. LINK - A direct connection from the input connector to link other speakers with same audio signal. GND LIFT - This switch lift the ground of the balanced audio inputs from the earth-ground of the amplifi er module.
PRESET BUTTON - This bu on has two func on:
1) Pressing it while powering on the unit:
ID ASSIGN the internal DSP assigns a new ID to the unit for the PRONET remote control opera on. Each loudspeaker must have a unique
ID to be visible in the PRONET network. When you assign a new ID, all the other loudspeakers with the ID already assigned must be ON and connected to the network.
2) Pressing it with the unit ON you can select the DSP PRESET. The selected PRESET is indicated by the corresponding LED:
STANDARD This PRESET is suitable for ver cal own arrays that may range from 4 to 8 boxes or for the centre region of a bigger own array.
It can be used also for stacked arrays.
LONG THROW This PRESET can be used in arrays bigger than 6 or 8 boxes and loaded in the top 1 or 2 boxes in order to obtain a more even
distribu on of the sound pressure, especially if they point very far away or to the upper deck of a large theatre.
DOWN FILL / This PRESET, which features a much smoother high frequency response, can be loaded in the bo om boxes (usually 1 or 2 SINGLE BOX boxes) of a large own array, in order to reach conveniently the audience close to the stage. This preset could be very useful
also when the box is used just on its own as a Front Fill element in the front of very large stages.
USER This LED lights when the USER PRESET is loaded. This preset corresponds to USER MEMORY no. 1 of the DSP and, as a factory
se ng, it’s the same to STANDARD. If you want to modify it, you have to connect the unit to a PC, edit the parameters with PRONET so ware and save the PRESET into USER MEMORY no. 1.
Note: see also the example further on this manual.
NETWORK IN/OUT - These are a standard RJ45 CAT5 connectors (with op onal NEUTRIK NE8MC RJ45 cable connector carrier), used for PRONET network transmission of remote control data over long distance or mul ple unit applica ons. TERMINATE - In a PRONET network the last loudspeaker device must be terminated (with an inner load resistance) especially in a long run cabling: press this switch if you want to terminate the unit.
AIMING and SUSPENDING INSTRUCTIONS
PREDICTION: EASE Focus 1
To aim correctly a complete system PROEL suggests to use always the Aiming So ware - EASE Focus 1: The EASE Focus 1 Aiming SoŌ ware is a two-dimensional, acous c simula on so ware that serves for the confi gura on and modelling of Line Arrays close to reality. It only considers the direct fi eld, created by the complex addi on of the sound contribu ons of the individual loudspeakers or array components. The design of EASE Focus is targeted at the end user. It allows the easy and quick predic on of the array performance in a given venue. The scienfi c base of EASE Focus stems from EASE, the professional electro- and room acous c simula on so ware developed by AFMG Technologies GmbH. It is based on the EASE Focus 1 system defi ni on fi les (Proel_AXIOM_AX2010P.EFO) required for its use. The EFO fi le contains the data that defi nes the Line Array with regard to its possible confi gura ons as well as to its geometrical and acous cal proper es. For detailed explana on of how to use the so ware and how to obtain a correct aiming refer to EASE Focus documenta on and other on-line manuals (h p://focus.afmg.eu/index. php/Focus_1.html).
WARNING! CAREFULLY READ THE FOLLOWING INSTRUCTIONS AND CONDITION OF USE:
• This loudspeaker is designed exclusively for Professional audio applica ons. The product must be installed by quali ed personal only.
• Proel strongly recommends that this loudspeaker cabinet be suspended taking into considera on all current Na onal, Federal, State and Local regula ons. Please contact the manufacturer for further informa on.
• Proel do not accept any liability for damage caused to third par es due to improper installa on, lack of maintenance, tampering or improper use of this product, including disregard of acceptable and applicable safety standards.
• During assembly pay a en
on to the possible risk of crushing. Wear suitable protec ve clothing. Observe all instruc ons given on the rigging components and the loudspeaker cabinets. When chain hoists are in opera on ensure that there is nobody directly underneath or in the vicinity of the load. Do not under any circumstances climb on the array.
KPTAX2012P Fly Bar and accessories
The AX2010 Systems are built to allow the suspension of array with variable shape and dimensions. Thanks to a suspension mechanism designed to be func onal, fl exible and safe, each system must be suspended or stacked using the KPTAX2012P fl y bar. The loudspeakers are linked together in a column using a series of couplers integrated in the frame of each enclosure. Each system is set up properly both acous cally and mechanically only using the aiming so ware. Coupling system in the front does not require any adjustment: using two locking pins, each loudspeaker box is fi xed to the previous. The slo ed bar in the back is inserted in a U-shaped frame which features a series of numbered holes. Sliding the slo ed bar in the U-shaped frame of the next loudspeaker and inser ng a locking pin in one of the numbered holes, it is possible to adjust the rela ve splay angle between two adjacent loudspeakers in the array column.
KPTAX2012P fl y bar maximum capacity is 700 Kg (1540 lbs) with the 0° angle. It can support up to 12 AX2010 loudspeakers with a safety factor of 7:1.
Follow the sequence in the fi gure for fi xing the fl y bar at the fi rst box. Usually this is the fi rst step before li ing up the system. Be careful to insert properly all the locking pins (2)(3) and the shackle (5) in the right holes as specifi ed by the aiming so ware. When lifting the system always proceed gradually step by step, paying a en on to secure the fl y bar to the box (and the box to the other boxes) before pulling up the system: this makes easier to insert properly the locking pins. Also when the system is released down, unlock gradually the pins. During the li ing be very careful to not let the cables enter the space between one enclosure and the other, as their compression could cut them.

KPTAX2012P FLY BAR AND ACCESSORIES
Fly bar suspension and angle setup (centre of gravity)
The fi rst fi gure shows where the normal centre of gravity is with one box or several boxes arranged in a line. Usually the boxes are arranged to make an arc for the best coverage of the audience, so the center of gravity moves backward. The aiming so ware suggests the ideal suspension pinpoint taking into account this behaviour: fi x the straight shackle in this posi on.
Note that the ideal aiming angle o en doesn’t correspond to the pinpoint: there is o en a li le diff erence between ideal aiming and real aiming and its value is the remaining angle: posi ve remaining angle can be adjusted a li le using two ropes, nega ve remaining angle are self adjusted a li le because the cables weighs on the back of the array. With some experience it’s possible to consider preven vely these required li le adjustments.
During the fl own set up you can connect the elements of the array to their cables. We suggest to discharge the weight of the cables from the fl ying pinpoint by tying them with a tex le fi bre rope, instead of le ng them hang freely: in this way the posi on of the array will be much more similar to the simula on produced by the so ware.
Pin locking and splay angles set up
The fi gure below shows how to insert correctly the locking pin and how to set up the splay angle between loudspeakers.
Wind loads
When planning an open-air event it is essen al to obtain current weather and wind informa on. When loudspeaker arrays are fl own in an open-air environment, possible wind eff ects must be taken into account. Wind load produces addi onal dynamic forces ac ng on the rigging components and the suspension, which may lead to a dangerous situa on. If according to the forecast wind forces higher than 5 b (29-38 Km/h) are possible, the following ac ons have to be taken:
- The actual on-site wind speed has to be monitored permanently. Be aware that wind speed typically increases with height above ground.
- Suspension and securing points of the array should be designed to support double the sta c load in order to withstand any addi onal dynamic forces.
WARNING!
Flying loudspeakers overhead at wind forces higher than 6 b (39-49 Km/h) is not recommended. If the wind force exceeds 7 b (50-61 Km/h) there is a risk of mechanical damage to the components which may lead to a dangerous situa on for persons in the vicinity of the own array.
- Stop the event and make sure that no person remains in the vicinity of the array.
- Lower and secure the array.

WARNING!
• The ground where the KPTAX2012P Fly bar serving as ground support is placed needs to be absolutely stable and compact.
• Adjust the feet so to lie the bar perfectly horizontal.
• Always secure ground stacked setups against movement and possible pping over.
• A maximum of 4 x AX2010 cabinets with the KPTAX2012P Fly bar serving as ground support are allowed to be set up as ground stack.
In the stack confi gura on you have to use the three op onal BOARDAC2P feet and the fl y bar must be mounted upside down on the ground. Coupling system in the front do not require any adjustment: using two locking pins each loudspeaker box is fi xed to the previous. The slo ed bar in the back is inserted in a U-shaped frame which features a series of numbered holes. Sliding the slo ed bar in the U-shaped frame of the next loudspeaker and inser ng a locking pin in one of the numbered holes, it is possible to adjust the rela ve splay angle between two adjacent loudspeakers in the array column. The op mal splay angles can be simulated using the EASE Focus 1 so ware.
POWER AMPLIFIERS
The AX2010A is powered by DA SERIES digital power modules, a new genera on of CLASS D power amplifi er with digitally-controlled SMPS. The innova ve technology used for these amplifi ers (including also the use of a variable switching frequency) off ers performances at the top of the range, such as a superior sound defi ni on at any audio frequency, very high dynamics also for low level signals and very low distor on even at the maximum power The superior sound quality can be compared with top-of-the-range AB-class analog systems, while the DA modules feature a higher dynamics, very compact size and light weight and effi ciency above 90%. The DA module employed for powering the AX2010A deliver in an ultra-compact package a maximum power of 2000W.
SIGNAL PROCESSING
The system processing is based on the CORE DSP pla orm, which has been designed by the PROEL R&D Laboratories using one of the most advanced SHARC DSP for audio applica on. It features 40bit, 96kHz fl oa ng point resolu on and high quality 24bit AD/DA converters, for a perfect signal integrity, a dynamic range in excess of 110dB and a superior sonic performance. Thanks to its massive processing power, the CORE pla orm is capable of providing the most sophis cated algorithms for speaker processing, together with remote control and networking capability. The PRONET control so ware, working on a solid and reliable CANBUS based network protocol, provides an intui ve interface for the remote control of the whole system, with the possibility of eqing, delaying, increasing the protec ons and monitoring the status of the amplifi er.
PRONET Network
PRONET so ware has been developed in collabora on with sound engineers and sound designers, in order to off er an “easy-to-use” tool to setup and manage your audio system. With PRONET you can visualize signal levels, monitor internal status and edit all the parameters of each connected device. You can ownload the PRONET so ware from the PROEL website at h p://www.proel.com (click on the link in the AX2010A product page).
The AXIOM ac ve loudspeaker devices can be connected in a network and controlled by the PRONET so ware. For the network connec on the PROEL USB2CAN converter op onal accessory is needed. The fi rst  me you connect a device with the USB2CAN converter, Windows O.S. will ask you to install the driver fi les, which you can fi nd in the Driver folder within the Pronet applica on folder (by default is C:\Program Files\Proel\Pronet\ Driver, or if you changed it <your path>\Driver). Please refer also to “Installa on” and “Drivers” paragraphs in the Pronet documenta on. The PRONET NETWORK is based on a robust, reliable and fast communica on protocol called CANBUS. The devices in a PRONET NETWORK are connected together with a “linear bus topology”. The USB2CAN converter must be connected to the network input of the fi rst device, the network output of the fi rst device is connected to the input of the second and so on. For the network connec ons simple RJ45 cat.5 or cat.6 ethernet cables can be used (please don’t confuse a ethernet network with a PRONET network these are completely diff erent and must be fully separated also both use the same kind of cable). The beginning and the end of a PRONET NETWORK must be terminated. One side is terminated by the USB2CAN converter, the other side must be terminated pressing the TERMINATE switch on the last device. All devices between these two points must have the TERMINATE switch li ed.
Assign the ID number
To work properly in a PRONET network each connected device must have a unique idenfi er number, called ID. By default the USB2CAN PC controller has ID=0 and there can be only one PC controller. Every other device connected must have its own unique ID equal or greater than 1: in the network cannot exist two devices with the same ID. An ID number is assigned automa cally to each devices when they are turned on for the fi rst  me connected to a network. In order to correctly assign a new available ID to each device for working properly in a Pronet network, follow these instruc ons:
1. Switch off all the devices.
KPTAX2012P STACKED ARRAY
CENTER OF GRAVITY
max splay angle 5°
max splay angle 10°
max splay angle 10°
max splay angle 10°
2. Connect them correctly to the network cables.
3. “TERMINATE” the latest device in the network connec on.
4. Switch on the fi rst device keep pressed “PRESET” bu on on the control panel.
5. Leaving the previous device switched on, repeat the previous opera on on the next device, un l the latest device is turned on. The “Assign ID” procedure for a device makes the internal network controller to perform two opera ons: reset the current ID; search the fi rst free ID in the network, star ng from ID=1. If no other devices are connected (and powered on), the controller assume ID=1, that is the fi rst free ID, otherwise it searches the next one le free. These opera ons ensure that every device has it’s own unique ID, if you need to add a new device to the network you simply repeat the opera on of step 4. Every device maintains its ID also when it is turned-off , because the idenfi er is stored in the internal memory and it is cleared only by another “Assign ID” step, as explained above. This means that if your network is made always of the same devices the assigning ID procedure must be executed only the fi rst  me the system is turned on.
For more detailed instrucƟ on about PRONET see the PRONET USER’S MANUAL included with the soŌ ware.
Useful tools to set up properly a verƟ cal array system
This is a list of tools that can be very useful to set properly a ver cal array system.
CABLE TESTER
It is a good prac ce to check all cables before each installa on, because even one faulty cable can compromise heavily the system performance.
INCLINOMETER WITH LEVER
This tool can be used to verify the ver cal array angle. It can be used at the top or at the bo om of the array In this case you have to sum all splay angles, so the maximum precision is needed for aiming the ver cal array, par cularly for long throw applica ons.
LASER DISTANCE METER
This instrument can be useful to measure the height of the ver cal array and to know the distance between FOH-Subs and FOH-Array for se ng the delay  me.
SMAART or similar acousƟ c measurement system
These are useful to measure delays, phase and response of the system.

EXAMPLE OF INSTALLATION IN A THEATRE WITH BALCONY
Here below you can see an example of the use of diff erent PRESETS in an AX2010 fl own array installed in a big theatre with balcony. The TOP BOXES of the array are aiming at the balcony while the DOWN FILL box is aiming at the audience close to the stage.
TOP BOXES: the power level at the end of the balcony is lower, as well as the high frequency level.
DOWN FILL BOXES: the power level in the proximity of the stage is higher, as well as the high frequency level.
In order to op mize the array performances for this specifi c applica on, the PRESETS should be used in the following way. Load the STANDARD preset in the central boxes. Load the LONG THROW preset in the TOP 1 or 2 boxes, in order to compensate the loss of power level and high frequencies of the program sent the upper deck of the theatre. Load the DOWN FILL / SINGLE BOX preset in the BOTTOM box in order to smooth the high frequency content of the program sent to the audience close to the stage.
