POWER AMPLIFIERS
The SW2100A is powered by DA SERIES digital power modules, a new generation of CLASS D power amplifier with digitally-controlled SMPS.
The innovative 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 definition at any audio frequency, very high dynamics also for low level signals and very low distortion 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 SW2100A features
also PFC (Power Factor Correction), a technology able to guarantee always the highest level of power regardless of any eventual fluctuations of
the power supply. It delivers in an ultra-compact package 2000W (@ 4 ohm) from each of its two channels: one channel is used to drive the 21”
woofer, the other, through an output SPEAKON connector, can power AX12C line array modules or other loudspeakers.
SIGNAL PROCESSING
The system processing is based on the CORE DSP platform, which has been designed by the PROEL R&D Laboratories using one of the most
advanced SHARC DSP for audio application. It features 40bit, 96kHz floating point resolution 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 platform
is capable of providing the most sophisticated algorithms for speaker processing, together with remote control and networking capability.
The PRONET control software, working on a solid and reliable CANBUS based network protocol, provides an intuitive interface for the remote
control of the whole system, with the possibility of eqing, delaying, increasing the protections and monitoring the status of the amplifier.
PRONET AX
PRONET AX 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 AX you can visualize signal levels, monitor internal status and edit all the parameters of each connected device.
You can download the PRONET AX app from the AXIOM website at http://www.axiomproaudio.com/.
The AXIOM active loudspeaker devices can be connected in a network and controlled by the PRONET AX software, for the network connection the
PROEL
USB2CAN
(with 1-port) or the
USB2CAN-D
(with 2-port) converter optional accessory is needed.
PRONET AX network is based on a “bus-topology” connection, where the first device is connected to the network input connector of the second
device, the second device network output is connected to the network input connector of the third device, and so on. To ensure a reliable
communication the first and the last device of the “bus-topology” connection must be terminated.
This can be done by pressing the “TERMINATE”
switch near the network connectors in the rear panel of the first and the last device.
For the network connections simple RJ45 cat.5 or cat.6
ethernet cables can be used (please don’t confuse a ethernet network with a PRONET AX network these are completely different and must be
fully separated also both use the same kind of cable).
Assign the ID number
To work properly in a PRONET AX network each connected device must have a unique identifier number, called ID. By default the USB2CAN-D 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.
In order to correctly assign a new available ID to each device for working properly in a Pronet AX network, follow these instructions:
1.
Switch off all the devices.
2.
Connect them correctly to the network cables.
3.
“TERMINATE” the end device in the network connection.
4.
Switch on the first device keep pressed “PRESET” button on the control panel.
5.
Leaving the previous device switched on, repeat the previous operation on the next device, until the latest device is turned on.
The “Assign ID” procedure for a device makes the internal network controller to perform two operations: reset the current ID; search the first free
ID in the network, starting 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 left free.
These operations 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 operation
of step 4. Every device maintains its ID also when it is turned-off, because the identifier is stored in the internal memory and it is cleared only by
another “Assign ID” step, as explained above.
With the network made always of the same devices the assigning ID procedure must be executed only the first time the system is turned on.

TOOLS
This is a list of tools that can be useful to set properly a vertical column array system or a complex point source system.
CABLE TESTER
It is a good practice to check all cables before each installation, because even one faulty cable can compromise heavily the system performance.
INCLINOMETER WITH LEVER
This tool can be used to verify the vertical array angle. It can be used at the top or at the bottom of the array In this case you have to sum all splay
angles, so the maximum precision is needed for aiming the vertical array, particularly for long throw applications.
LASER DISTANCE METER
This instrument can be useful to measure the height of the vertical array and to know the distance between FOH-Subs and FOH-Array for setting
the delay time.
ACOUSTIC MEASUREMENT SYSTEM
(SMAART, SATlive or similar)
These are useful to measure delays, phase and response of the system.
