INTRODUCTION
The AX12LF Line Array is a passive system equipped with twelve 3.5” long-excursion neodymium transducers with
waterproof cones, designed to provide low-frequency extension for AX12C and AX6C mulple systems.
Wherever a subwoofer is not needed, such as in speech applicaons or corporate events, the AX12LF provides a one
octave low frequency extension to the AX12C and AX6C. The same lightweight aluminum frame box and the common
suspension systems allow perfect integraon with AX12C and AX6C elements.
The AX12LF line array module can be combined in dierent conguraons with the AX12C (or AX6C – basically two
AX6C correspond to one AX12C). Possible conguraons range from a simple two-unit column with one AX12C plus one
AX12LF suspended or installed on the ground, four-unit columns with one AX12LF at the base or one at the base and
one at the top, and very large suspended systems with four AX12C and two AX12LF at the back (end re conguraon).
The AX12LF can be powered using QC Series Class D processed ampliers. Dierent presets for dierent combinaons
are available for the built-in CORE DSP, which can be also remotely controlled using PRONET AX soware.
Thanks to the elegant mechanical design the AX12C can be easily transported, while the integrated suspension
system makes its deployment very fast and simple. Each unit comes with two aluminum brackets and four pins that
allows mulple array elements to be easily combined either together or with AC12C and AX6C elements, or also in
combinaon with the complete range of mounng hardware available, including ybar and several brackets and stands.

the 4 screws indicated
in the figure.
In case you decide to remove
the AX12LF bracket (because
it is not needed), put back
the screws in the threaded
holes as shown in the figure,
in order to avoid air leakage.

REAR PANEL
INPUT & LINK - Both connectors at the top and the boom of the AX12LF can operate as input or link, to
connect an appropriated processed amplier or to link the column to a second one.
The AX12LF does not include an internal passive crossover for ltering the signal, but only an internal
protecon that excludes the internal speaker to protect them from excessive input power. The protecon
should not trip with a typical music program, but only with a massive and constant power signal, like a
feedback. The connecons are the following:
INPUT - LINK
NL4 pin number internal connecon
1+ + speakers (pass thru link speakon)
1- - speakers (pass thru link speakon)
2+ + no connecon (pass thru link speakon)
2- - no connecon (pass thru link speakon)
WARNING: the maximum quanty of AX12LF that can be linked together depends by the load capacity of the appropriate processed
amplier. When powered from the QC2.4 and QC4.4 suggested ampliers, a maximum of two AX12LF can be connected to each power
output.
TOOLS
This is a list of tools that can be useful to set properly a vercal column 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.
ACOUSTIC MEASUREMENT SYSTEM (SMAART, SATlive or similar)
These are useful to measure delays, phase and response of the system.

PREDICTION: EASE Focus 3
To aim correctly a complete system we suggests to use always the Aiming Soware - EASE
Focus 3.
The EASE Focus 3 Aiming Soware is a 3D Acousc Modelling Soware that serves for the
conguraon and modelling of Line Arrays and convenonal speakers close to reality. It only
considers the direct 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 scien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 GLL loudspeaker data le required for its use:
AXIOM_Column_vX_X. The GLL le contains the data that denes the Line Array with regard
to its possible conguraons as well as to its geometrical and acouscal properes.
Download the EASE Focus 3 app from the AXIOM website at hp://www.axiomproaudio.com/ clicking on downloads secon of the product.
Use the menu opon Edit / Import System Denion File to import the le AXIOM_Column_vX_X from the installaon Data folder, the detailed
instrucons to use the program are located in the menu opon Help / User’s Guide.
Note: Some windows system can require the .NET Framework 4 that can be download from microso website at hp://www.microso.com/en-
us/download/default.aspx.

Installaon using KPTAX12C ybar
Using the KPTAX12C y bar it is possible to assemble a suspended and unobtrusive vercal array system
with a variable size up to 4 elements of AX12C, or a combinaon of AX12C, AX6C and AX12LF without
exceeding the 120Kg maximum load capacity. The loudspeakers are linked together in a column using
the brackets integrated at each end of the enclosure. Each system can be set properly both acouscally
and mechanically using the aiming soware.
Each loudspeaker box is xed to the next one using the two locking pins. The locking pin in the front
does not require any adjustment, while the locking pin in the back is used to adjust the splay angle
between two adjacent loudspeakers in the array column at 0° or 2°.
Follow the sequence in the gure for xing the ybar to the rst box. Usually this is the rst step before
liing up the system. Be careful to insert properly the shackle (1)(2) and the locking pins (3)(4) in the
right holes specied by the aiming soware.
When liing the system always proceed gradually step by step, paying aenon to secure the ybar
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.
The centre of gravity of an AX12C/AX6C/AX12LF array depends on the number of units and on the
splay angle between the units, when the units are arranged to make an arc for the best coverage of the
audience. Use always the aiming soware to dene the correct suspension pinpoint where to x the
straight shackle and the opmal splay angle between units.
Note that the ideal aiming angle oen doesn’t correspond to the pinpoint: there is oen a lile
dierence between ideal aiming and real aiming and its value is the Delta angle: posive delta angle
can be adjusted a lile using two ropes, negave delta angle are self adjusted a lile because the cables
weights on the back of the array. With some experience it’s possible to consider prevenvely these
required lile adjustments.
During the 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 ying pinpoint by tying them with a texle bre rope, for
this reason a ring is present at the end of the ybar that can be used to x the cable 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.
Wind loads
When planning an open-air event it is essenal to obtain current weather and wind informaon. When
loudspeaker arrays are own in an open-air environment, possible wind e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 bft (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!
AX6C, AX12C and AX12LF must be suspended only using the ying bar KPTAX12C, with a
maximum of 120Kg per ying bar.
CONDITIONS OF USE
PROEL does not accept any liability for damage caused to third parties due to improper
installaon, use of non-original spare parts, lack of maintenance, tampering or improper use of
this product, including disregard of acceptable and applicable safety standards.
PROEL strongly recommends that this loudspeaker cabinet be suspended taking into
consideraon all current local regulaons. The product must be installed by qualied personnel.
Please, contact the manufacturer for further informaon.

System Processing basic instrucon
The AX12L needs an external processor to take care of the ltering, the me alignment and the speaker protecon. It must be powered using
QC2.4 or QC 4.4 processed ampliers, with the proper preset loaded into the internal processor, according to the number of columns connected.
1x12LF+1x12C: this PRESET should be used for one AX12LF coupled with one AX12C.
1x12LF+2x12C: this PRESET should be used for one AX12LF coupled with two or three AX12C. This preset can also be used when two AX12LF are
coupled with four AX12C.
Using the PRONET AX soware, addional EQ, LEVEL and DELAY adjustment can be added to the basic presets and new presets can be saved in
the QC amp user memories.
