AVN-Portals 1
Introduction
Fig 1-1: The AVN-Portal Front Panel
Fig 1-2: The AVN-Portal Front Panel with Meter Display
The AVN portals are part of the Sonifex range of IP based AVN (Audio/
Video/Network) products. The portals consist of three multi-channel audio
mix engine interfaces which can perform mixing and routing of audio from
physical analogue, AES3 and microphone inputs and also from AoIP (Audio
over IP) input streams, using a comprehensive browser-based mix matrix.
The inputs can be routed to analogue and AES3 physical outputs and to
AES67 and RAVENNA compatible AoIP output streams.
The audio levels of each physical input and output can be adjusted and can
be monitored using the meter displays.
For more information on the AVN product range please refer to the
separate guide entitled “Guide to Media Networking & Configuration of the
AVN Product Range”.
All of the units also allow input from up to 8 AoIP streams with a maximum
of 16 AoIP input channels which can be routed. The units provide up to 8
AoIP output streams with a maximum of 8 channels per stream providing
up to 64 stream outputs. The level of each routing can be individually
adjusted at the input, output or crosspoint along with the addition of a
high-pass and low-pass filter on all inputs and outputs.

• Dual 1Gb Ethernet & 1Gb SFP port.
• Dual AC & DC power supply inputs.
• 10 user assignable GPIO ports.
The AVN portal range can transmit and receive audio using AoIP with
support for both RAVENNA and AES67. AoIP input streams are discovered
and output streams are advertised using Avahi/Bonjour and SAP.
The rear panel contains IEC mains and DC power inputs which allow for power
redundancy. There are also two ethernet RJ45 connections (control and AoIP)
and an SFP (Small Form-factor Pluggable) port. This allows the user to install
an SFP transceiver of their choice such as a 1Gbit/s copper or optical SFP
transceiver. When an SFP is used, this replaces the AoIP RJ45 connection.
Each portal has a configurable GPIO system, with 10 physical ports (provided
by a D-Sub or terminal block connection) and 10 virtual ports, which can
be user configured as inputs or outputs and provide software-controlled
functionality. A voltage free relay contact is also available on the physical port
which can be used to operate external equipment.
Audio connectivity is available with either RJ45/XLR and D-Sub connectors or
terminal block connectors. The AVN-PM8 also supports microphone inputs
and phantom power. If phantom power is activated, the associated LED on the
back panel of the device is illuminated.
A built-in web server allows the user to modify and backup the device’s
configuration and apply firmware updates. An Ember+ interface also gives
access to the unit’s configuration as well as providing remote control and
monitoring of the GPIO and virtual GPIO ports.
The front panel provides status information and allows some of the device
configuration to be modified directly. The front panel has an OLED display
used to display these menus. The front panel controls also include user
configurable buttons which can be set-up to perform actions such as
activating a GPIO or as a shortcut button to jump to a specified menu on the
OLED display.
A meter display can be added to any of the portals, this provides a live display
of the levels of the physical inputs and outputs. It is also possible to select a
single input or output and view its metering data in a more detailed view. The
scale used on the meter is also user configurable. On devices without a meter
display, a smaller display is shown on the main OLED display.

AVN-Portals 1
The portals can be combined with the Sonifex AVN-HA1 and
AVN-HD1 headphone amplifiers to provide 8 separate headphone
signals where each headphone amplifier can be sent a separate
feed, mixed from any physical or stream inputs. On portal units
with RJ45 outputs, an AVN-HA1 (for the AVN-PA8 and AVN-PM8)
or AVN-HD1 (for the AVN-PD8) headphone amplifier can be used
to listen to the outputs, with the portals providing power and audio
signals. The switches on the front panel of the AVN-HA1 and AVN-
HD1 can be used as another GPI for muting the output (in the GPIO
settings menu these are known as ‘Cough Ports’). Please refer to the
Sonifex website for more information on the AVN-HA1 and AVN-HD1
headphone amplifiers.

3. Once the unit has started and the main screen is shown on the OLED
display, open a web browser and connect to the unit by entering
the URL: http://192.168.0.100 into the browser address bar. Once
connected, the device information web page will be shown.
4. On the web page, select Network from the configuration tab and
configure the Ethernet and AoIP ports to the required settings. The IP
addresses assigned to the 2 ports must be on different subnets. For
example, with the subnet mask on both ports set to 255.255.255.0, if
the IP address on the Ethernet port is set to 192.168.0.100, the AoIP
port must be set to 192.168.x.y where x is not 0 and y is unique on the
chosen subnet.
5. Although not essential at this point, it is a good idea to assign a
recognisable friendly name so that other users can easily identify and
use services from this unit.
6. To simplify the configuration process, make sure the Auto Multicast
option is enabled. This removes the need to set the transmit AoIP
multicast IP addresses as they will be configured automatically based
on the AoIP port IP address. Once the settings on the network page
have been configured, press the submit button to save them to the
connected unit. When the network settings have been changed, the
unit will automatically restart. If the settings of the network port the
browser is connected to have changed, a new browser connection will
need to be established using the new IP address. If dynamic address
mode has been selected, the active IP address for the network port
can be found by going to the system info menu on the front panel. See
System Info menu item on page 54 for details.
7. If a dedicated grandmaster clock, such as the AVN-GMC from Sonifex, is
going to be used as the master PTP clock for the network audio system,
the PTP profile on the portal will need to be set to the current setting
on the grandmaster device. On the web page, select PTP Profiles from
the configuration tab. Select the required profile from the drop-down
list box and ensure that the domain number for the selected profile
matches the grandmaster setting. Press the submit button to save the
new settings. If no dedicated grandmaster device is used, all PTP aware
devices in the network will automatically establish a master clock
hierarchy. In this case, the default profile can be used.
8. Connect the lower AoIP port to the audio network.
9. On the web page, select Audio Routing from the Configuration tab. A
routing grid can now be seen with inputs down the left-hand side and
outputs along the top. By clicking on a square in the routing table, the
channels for the input and output corresponding to that square will
be shown, clicking the square at which two channels meet routes the
input channel to the output channel. Where an input is routed to an
output, the square will be highlighted in green. Clicking on an existing
routing raises a dialog box which allows the user to modify the mix
level or remove the routing. (An existing routing can also be removed
by holding the Ctrl key and clicking on it).
10. AoIP input streams can be added to the routing grid by clicking ‘Add
AoIP In Stream’. A dialog box will be shown containing a list of the
discovered AoIP streams. Select a stream from the list and click ‘Add’.
11. AoIP output streams can be added to the routing table by clicking ‘Add
AoIP Out Stream’. A dialog box will be shown and a stream can be set
up by typing in an AoIP stream name and clicking ‘Add’.
12. Clicking on the name of an input or output raises a dialog which allows
various settings such as Trim and EQ of the input or output to be
adjusted.

Installation 3
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.
