CX15A
ac ve stage monitor loudspeaker
KEY FEATURES
• High-Output Coaxial Stage Monitor • 80° constant coverage
• Very compact size • 96KHz / 40 bit fl oa ng point CORE processing with PRONET remote control
• Low-profi le design • Digitally controlled Class D amplifi er module with SMPS
INTRODUCTION
The CX15A is a coaxial stage monitor designed specifi cally for live sound, even if the low-
profi le enclosure is suitable also for theater and television applica ons. The high-performance
coaxial transducer employed provides good sound balance and great intelligibility even at
very high power.
The high frequency range is reproduced by a low-distor on compression driver, equipped with
pure Titanium diaphragm. An edgewound aluminum ribbon voice coil and a copper sleeve
reduce distor on and increase the unit’s output. The special shape of the cone allows a precise
and controlled conical dispersion of 80°.
The 15” woofer employed in the reproduc on of the low frequency range is equipped with a
special interleaved sandwich 3” voice coil and an aluminum demodula on ring for minimum
distortion. A single powerful neodymium magnet guarantees high performance with a
consistent weight reduc on.

I/O AND CONTROL OPERATIONS
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.
MAINS 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 CX15A loudspeakers, with 120V~ we suggest to link a maximum of 2 CX15A loudspeaker.
INPUT - Audio signal input with locking XLR connector. It has a fully electronically
balanced circuitry including AD conversion for the best S/N ratio and input
headroom.
LINK - A direct connec on from the input connector to link other speakers with
same audio signal.
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 amplifi er 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.
GND LIFT - This switch li the ground of the balanced
audio inputs from the earth-ground of the amplifier
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:
NORMAL WEDGE This PRESET is suitable for typical stage monitor applica ons. It
can be used also when the CX15A is used mounted on a pole.
COUPLED UNITS This preset provides the correct EQ when two CX15A monitors,
fed with the same audio signal, are placed at no more than 0,6 m (2 feet) one to the other. To be used for double stage
monitoring for singers or other musicians.
LOW CUT This PRESET is the same as NORMAL WEDGE but with a low cut at 110 Hz 48 dB/oct. To be selected when a CX15A is used
in combina on with a subwoofer to form a DRUM FILL or a SIDE FILL system. It can be used also in case you need to cut
dras cally the monitor LF response.
USER The USER PRESET corresponds to the fi rst USER MEMORY (Preset 4-U) stored in the DSP and, as a factory se ng, it’s the
same as NORMAL WEDGE. If you want to modify it, you have to connect the unit to a PC, edit the parameters with PRONET
so ware and save it into “Preset 4-U-your_preset_name” (see also further in 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.

POWER AMPLIFIERS
The CX15A 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 CX15A 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 DIRECTIVITY MAP fi gure shows the op mal behaviour obtained with
the combina on of loudspeakers and DSP used within CX15A.
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 software has been developed in collaboration 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.
Download the PRONET app from the AXIOM website at hƩ p://www.axiomproaudio.com/ clicking on downloads secƟ on of the product.
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 iden fi 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.
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 iden fi 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.

EDITING USER PRESETS
If you connect the CX15A to a PC, using PRONET Control So ware you can edit the user presets. In par cular, the user preset no.
4-U can be loaded also from the unit’s control panel without the need to connect again the loudspeaker to PRONET.
Here below there is a a brief explana on about how to edit the main DSP parameters.
In/Out - Level: adjusts the input level gain in the range of -30 ÷ +6 dB (this is a digital control a er the A/D converter).
In/Out - Input Meter: shows the input level signal a er the A/D converter. Green LED indicates the normal opera ng level before nominal input
sensi vity (+4 dBu), yellow LED indicates that the signal exceeds the nominal sensi vity, red LED indicates digital clipping and must be avoided.
In/Out - Compressor/Limiter: this is a compressor/limiter for the input signal, that can be used to increase loudness and transparency (for the
best results, we recommend to not change the factory se ngs).
In/Out - Output Level Trim: use these controls in you want to trim fi nely the level of woofer and HF driver.
In/Out - MUTE: these bu ons can be used to switch off the woofer or the HF driver in order to check the system.
In/Out - Input Delay: edit this box to apply a delay to the speaker, to be used pically if you need to align in me the speaker to another sound
source. Note: a delay higher than 10 mS (3 m) is easily audible and it can be annoying to singers and musicians.
PEQ - EQ1-5: 5-band full parametric EQ. Note: CX15A is already opƟ mized for the best performance for wedge monitoring, so we suggest to make
only small adjustments.
Setup - Device Name: here you can assign a unique name at the unit (twelve characters are available).
Setup - Device Group: here you assign the unit to a group, so when the LINK func on on PRONET so ware is ac vated, you can automa cally set
the same parameters to all the units assigned to the same group.
