3. Installation
Network Connection
All devices in the AVN portal series have two gigabit ethernet network
ports.
Upper Port: Configuration and control interface.
Lower Port: Audio over IP (AoIP) interface.
In an ideal installation, the lower port should be connected to a dedicated
network switch that handles audio and audio related traffic only. All
other AoIP sources and destinations, and grandmaster clocks should be
connected to this network. The upper port can then be connected to a
separate network to provide access to the embedded web server. With this
setup, potentially heavy network traffic on a company LAN does not affect
the performance of the AoIP network.
The AVN portals can be used with a single network connection using the
lower (AoIP) port as this also provides access to the embedded web server.
The AoIP sources and destinations, and grandmaster clocks should still
ideally be connected to a dedicated network switch.
Audio Inputs
The AVN-PA8 has 8 analogue balanced stereo inputs. The AVN-PD8 has 8
digital AES3 inputs and the AVN-PM8 has 8 balanced mono mic/line inputs.
These audio inputs can be monitored using the meter display if fitted,
otherwise confidence metering is available on the OLED display. These
inputs can be routed to any of the devices physical outputs and any of the
AoIP output streams. This routing can be controlled through the devices
webserver.
Audio Outputs
The AVN-PA8 has 8 analogue balanced stereo outputs. The AVN-PD8 has
8 digital AES3 outputs and the AVN-PM8 has 8 analogue balanced stereo
outputs. These audio outputs can be monitored using the meter display
if fitted, otherwise confidence metering is available on the OLED display.
The audio sent to these outputs can be routed from any of the physical and
AoIP input streams. This routing is controlled through the webserver.
GPIO
All devices in the AVN portal series have a GPIO connector, this GPIO
connector provides the device with 10 physical GPIO ports and a single
output relay. Each GPIO port can be disabled, used as an input or used as an
output. All devices in the series also have 10 virtual GPIO ports available. All
GPIO and relay settings can be configured through the devices webserver.
All units with RJ45 type outputs provide an extra 8 GPI ports that can be
used in conjunction with the AVN-HA1 (for the AVN-PA8 and AVN-PM8) or
AVN-HD1 (for the AVN-PD8). The settings for these GPIO ports can also be
configured through the webserver and are known as Cough Ports.
Power Supply
The unit can be powered from the mains via the supplied IEC lead, or by
using the optional external 12V DC power supply, part number AVN-DC150.
Please contact Sonifex Ltd sales for more details. Both power supplies can
be connected and powered at the same time to provide redundancy if
required.
