Network Controller
The network control unit is the heart of the SemSound system. The unit routes up to 28 simultaneous audio chan‑
nels, 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 configu‑
ration. The controller can operate independently of the PC. However, the controller can use a PC to display infor‑
mation 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 SemSound network controller needs SemSound software version 4.0 or higher.
Features
• Public address and emergency sound system control unit
• Control and routing of 28 simultaneous audio channels
• Ethernet interface for configuration, control, diagnostics, and logging
• Digital storage for pre‑recorded messages
• EN 54‑16 and ISO 7240‑16 system certification
Functions
Connectivity
The network controller has four analog audio inputs. Of these, two are selectable between microphone and line.
The other two inputs are fixed as line inputs. The microphone/line inputs can be used as call inputs, if they are
programmed conditionally to any of the eight control inputs, which are freely programmable for system actions,
with freely programmable priorities. The line inputs provide selectable 20 kHz pilot tone detection for cable super‑
vision.
The controller has four analog audio line outputs each with a selectable 20 kHz monitoring signal. Three control
outputs are programmable for faults or calls, and two others are used to connect visual and audible fault indica‑
tors.
A 24 Vdc auxiliary output is available that can be used to power an external visual fault and/or emergency light tower.
