CX15A

acve stage monitor loudspeaker

KEY FEATURES

• High-Output Coaxial Stage Monitor • 80° constant coverage

• Very compact size • 96KHz / 40 bit ﬂoang point CORE processing with PRONET remote control

• Low-proﬁle design • Digitally controlled Class D ampliﬁer module with SMPS

INTRODUCTION

The CX15A is a coaxial stage monitor designed speciﬁcally for live sound, even if the low-

proﬁle 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 ampliﬁer on, insert the Powercon®

connector and turn it clockwise into the ON posion. To switch the ampliﬁer 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 speciﬁcaƟons

indicated on the ampliﬁer unit. The power supply must be protected by a suitably rated thermo-magneƟc

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 ampliﬁer 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.

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 ﬁrst 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 ampliﬁer with digitally-controlled SMPS.

The innovave technology used for these ampliﬁers (including also the use of a variable switching frequency) oﬀers performances at the top of

the range, such as a superior sound deﬁni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 eﬃciency 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

SHARC DSP for audio applicaon. It features 40bit, 96kHz ﬂoa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 ﬁgure 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 ampliﬁer.

PRONET Network

PRONET software has been developed in collaboration with sound

engineers and sound designers, in order to oﬀer 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 hƩp://www.axiomproaudio.com/ clicking on downloads secƟon 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 ﬁrst me you connect a device with the USB2CAN converter, Windows O.S. will ask you

to install the driver ﬁles, which you can ﬁnd 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 ﬁrst device, the network

output of the ﬁrst 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 diﬀerent 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ﬁer 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 ﬁrst 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 oﬀall the devices.

2. Connect them correctly to the network cables.

3. “TERMINATE” the latest device in the network connecon.

4. Switch on the ﬁrst 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 ﬁrst 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 ﬁrst 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ﬁer 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 ﬁrst me the system is turned on.

EXAMPLE OF PRONET NETWORK WITH CX15A WEDGE MONITOR

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 ﬁnely the level of woofer and HF driver.

In/Out - MUTE: these buons can be used to switch oﬀthe 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 opƟmized 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.
