9. NW6031 Audio Hub
9.1 General
The Audio Hub is contained in an extruded aluminum housing. The NW6031 Audio Hub is
powered from and communicates with the NW6000 using PoE. The audio hub provides 6 audio
input channels which are simultaneously sampled. Digital processing used within the hub to
convert sampled analogue data for communications back to the NW6000 over the PoE
communications port.
Characteristics.
• IEC 61996 compliant inputs for use with NW6030
Analogue Microphones
• IEC60945 compliant
• Powered from the NW6000 over PoE
• Each channel independently programmable for either
NW6031 or VHF inputs.
9.2 Location and mounting
One or more NW6031Audio Hubs may be used
with the NW6000. The NW6030 requires a PoE
connection with a maximum cable distance from
the NW6000 of 100m
The total maximum cable distance between
microphone and Audio Hub (NW6031) is 150m.
The audio hub uses pluggable terminal blocks for
connecting to audio sources to be recorded. The
NW6030 Analogue Microphone can be located
150m away from the audio hub.
The NW6030 is required to be located in a
protected environment using the mounting points
are indicated in the outline drawing.
9.3 Power
The power budget for the NW6031 with 6x
NW6030 analogue microphones is 4W.
No external power supply is required for use with the NW6030 or NW6031 as the NW6000
provides power to both via the NW6031 Audio Hub.
