POWER AMPLIFIERS
The SW218A 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 two DA modules employed for powering the SW218A deliver
in an ultra-compact package a maximum power of 4000W.
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 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
PRONET so ware has been developed in collabora on 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.

The SW218A loudspeaker devices can be connected using the network connec on, in this case 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.
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 o
ff
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-o
ff
, 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.
