POWER AMPLIFIERS
The SW215A 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 two DA modules employed for powering the SW215A deliver
in an ultra-compact package a maximum power of 2000W.
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
PRONET software has been designed by Proel’s Research & Development Department to easily control a single unit or a network of devices, like
active loudspeakers or speaker processors, equipped with the C-AUDIO CORE digital processing platform.
PRONET 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 PROEL website at http://www.proel.com clicking on support / download section.
The SW218A loudspeaker devices can be connected using the network connection, in this case the PROEL USB2CAN converter optional accessory is
needed. The first time 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 application folder (by default is C:\Program Files\Proel\Pronet\Driver, or if you changed it <your path>\Driver).
Please refer also to “Installation” and “Drivers” paragraphs in the Pronet documentation.
The PRONET NETWORK is based on a robust, reliable and fast communication 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 connections 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 lifted.
Assign the ID number
To work properly in a PRONET network each connected device must have a unique identifier 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 automatically to each devices when they are turned on for the first time 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 instructions:
1. Switch off all the devices.
2. Connect them correctly to the network cables.
3. “TERMINATE” the latest 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. This means that if your network is made always of the same devices the assigning ID procedure must
be executed only the first time the system is turned on.
