The network control unit is the heart of the Praesideo
system. The unit routes up to 28 simultaneous audio
channels, delivers power to the system, reports faults,
and controls the system. Audio inputs can be
announcements from call stations, background music,
or local audio. The network control unit can be
configured for the most complex public address
systems. The configuration can be done comfortably
and efficiently via a PC. The PC is only needed for
configuration. The controller can operate
independently of the PC. However, the controller can
use a PC to display information on the system status
using the software, supplied with the unit. The unit
can be freestanding on a tabletop or mounted in a 19″
rack.
The PRS‑NCO3 network controller needs PRS‑SW
software version 4.0 or higher.
