QFlex - Brochure

An RS485 interface is used for the serial
data, with a twisted pair to send and
receive information to a high number of
nodes over very long distances. Operating
a shared bus system, so that a single
computer can control any node on that
bus, also means that status information can
be gathered from any of the devices.
The RS-485 differential signal is very
robust, while its noise immunity and long-
distance capability ensure it is one of the
most popular communications methods
used in industry. Only data to control setup
functions and ongoing system diagnostics
is carried over the network. As each VNET
loudspeaker controls its own DSP functions
any unforeseen problem would be isolated
to only that particular node and audio will
still be delivered.
Speakers are automatically identied on
the network software setup screen with
factory default names. The name can be
edited to reect their actual location on the
network, with physical location conrmation
by selecting the ‘Locate’ function to
activate an LED mounted on the front of
the loudspeaker. The loudspeakers are fully
calibrated at the factory, avoiding the need
to input the correct speaker management
settings or any dynamics at the point
of install.
