CONNESSIONE XLR
The XLR connection is a type of balanced connection that allows the con-
nection of devices over long distances without loss of quality due to the
background noise detected.
This is made possible by the presence, as well as by the mass (pin 1), of
two cables: a signal cable (pin 2) and a 180° dephased signal cable (pin
3); at the opposite end of the signal source, on both these cables, in addi-
tion to the actual signal, the same quantity and type of background noi-
se possibly detected along the path or inevitably produced by the cables
(not the one for thermal agitation) will be present in phase. The signal will
then be taken from the two cables by difference: in this way the useful
part will be double amplitude while the noise detected or produced along
the path, being present in phase on both cables, will be cancelled by the
difference operation. In the three-pin version it is normally used for the
termination of balanced audio lines but it is often also used for unbalan-
ced signals creating a short circuit between the mass and the cold pin.
The EIA RS-297-A standard requires that the three-pin XLR connectors
for balanced audio are wired as shown in fig.
CONNESSIONE ETHERNET
Neutrik etherCON connectors provide solutions for data transfer
®
and more in harsh and demanding environments.
The etherCON series is a robust and lockable RJ45 connector system op-
timized for professional audio, video and lightning network applications.
Thanks to the possibility of networking, the models of the Horizon series
can be remotely controlled thanks to the INFINITO System Management
Suite software.
Support for DANTE Digital Sudio Networking
