POWER AMPLIFIERS
The CX15A is powered by DA SERIES digital power modules, a new genera on of CLASS D power ampli fi er with digitally-controlled SMPS.
The innova ve technology used for these ampli fi ers (including also the use of a variable switching frequency) o ff ers performances at the top of
the range, such as a superior sound de fi 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 e
ffi 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 ampli
fi er.
PRONET Network
PRONET software has been developed in collaboration with sound
engineers and sound designers, in order to o
ff 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 h Ʃ p://www.axiomproaudio.com/ clicking on downloads sec Ɵ 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 di ff 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.
