Input: Dante Digital Audio
A single network cable delivers 4 channels of audio and Power over Ethernet (PoE). Use Dante Controller to route audio chan
nels from the network to the network interface.
Output: Analog (4 XLR or Block Connectors)
Each output sends a discrete audio channel to connect to an analog device.
Setting up the Audio Network
Shure networked conferencing systems are comprised of Microflex Advance microphones and network interfaces, which oper
ate entirely on a Dante network. Additional hardware, including network switches, computers, loudspeakers, and audio proces
sors are described in the hardware component index.
Shure components shown in this diagram:
Microflex Advance Microphones
The MXA910 and MXA310 are equipped with Dante outputs, and connect directly to a network switch.
Audio Network Interfaces
The interfaces are used to connect analog devices such as loudspeakers and analog microphones to the network.
ANI4IN: Converts 4 analog signals (separate XLR and block connector models available) into Dante digital audio signals.
ANI4OUT: Converts 4 channels of Dante audio from the network into analog signals.
This diagram shows the entire signal path through a networked conference system. Signals from the near end and far
end are exchanged through an audio processor connected to a phone system, or through a computer connected to
the internet. Analog microphones connect to the network through the Shure ANI4IN, while loudspeakers connect
through the Shure ANI4OUT.

Shure Incorporated

This diagram shows Microflex Advance components in context, with two rooms communicating through video codecs.
Controlling Hardware and Audio Over the Network
Audio and hardware settings are managed through a computer connected to the same network.
Shure Hardware and Audio
Each Microflex Advance component has a web application which provides mixing and configuration tools to optimize sound
quality.
Expanded Control for Analog Devices
Analog devices that are connected to the network through a Shure network interface (ANI4IN/ANI4OUT) benefit from additional
remote control: Volume levels, equalization, and signal routing are managed through the web application. For example, adjust
ing loudspeaker volume or muting a wired microphone, which would normally be done from the hardware, can now be con
trolled remotely over the network.
Dante Signal Routing
You can manage signal routing with Dante Controller or Shure Designer software.

Summing
The Audio Network Interface provides channel summing to combine Dante signals from the network, and send them over a sin
gle analog output. This makes it possible to send all channels to a device with a limited amount of analog input channels. Mixer
functionality does not change; audio channels are simply sent as one combined signal.
Note: When summing is enabled, a limiter is activated to prevent signal overloading. The limiter never applies to the direct outputs, and only affects the
summed signal.
To enable, select one of the summing options in the toolbar at the top of the mixer in the channels tab.
Encryption
Audio is encrypted with the Advanced Encryption Standard (AES-256), as specified by the US Government National Institute of
Standards and Technology (NIST) publication FIPS-197. Shure devices that support encryption require a passphrase to make
a connection. Encryption is not supported with third-party devices.
To activate encryption:
Open the Settings menu and select the General tab.
Select Enable Encryption.
Enter a passphrase. All devices must use the same passphrase to establish an encrypted connection.
Important: For encryption to work, all Shure devices on your network must use encryption.
If you’re using Shure Designer software to configure your system, please check the Designer help section for more about this topic.

browser. The DNS name is derived from model of the unit, in combination with the last three bytes (six digits) of the MAC ad
dress, and ending in .local.
Format Example: If the MAC address of a unit is 00:0E:DD:AA:BB:CC, then the link is written as follows:
ANI4IN: http://ANI4IN-aabbcc.local
ANI4OUT: http://ANI4OUT-aabbcc.local
Firmware Updates
Firmware is embedded software in each component that controls functionality. Periodically, new versions of firmware are devel
oped to incorporate additional features and enhancements. To take advantage of design improvements, new versions of the
firmware can be uploaded and installed using the Shure Update Utility. Software is available for download from http://
www.shure.com.
Important: When components are connected through the Shure MXW Audio Network Interface, their firmware must be updat
ed on one device at a time prior to updating the MXW Audio Network Interface firmware. Attempting to update all devices at
once will cause the interface to reboot after its firmware is updated, and the connection to other networked components will be
lost.
Perform the following steps to update the firmware:
CAUTION! Ensure the device has a stable network connection during the update. Do not turn off the device until the update is complete.
Connect the device and computer to the same network (set to the same subnet).

Levels and Metering
Adjusting Input levels
Check the source level before it reaches the Network Interface:
Verify that the networked microphones or other Dante sources are operating at nominal output levels.
Levels for Microflex Advance™microphones are adjustable through their web application.
Adjust the digital gain in the Network Interface web application:
Use the faders or manually enter a gain value.
The digital gain adjusts the level of the signal before it reaches the analog circuitry.
Set these levels as high as possible without reaching the peak level (0 dB) on the meter.
Adjusting Output Levels
Access the analog output levels through the web application, by selecting an output level from the Analog Gain (dB) pull-down
menu. Match the output level from the Network Interface to the input sensitivity on the analog device:
Line level (0 dB)
Aux level (-20 dB)
Microphone level (-46 dB)
LED Signal and Clipping Indicators
Each analog output channel has a corresponding LED:
Green: Audio signal present
Red: Audio signal is clipping and should be attenuated.
Note: the meters in the web application are not affected by the Analog Gain (dB) setting.
Pre- and Post-Fader Metering
There are two modes for monitoring so that both the input and output signals can be monitored separately.
When set to pre-fader, the meter displays the signal level from the source on the Dante network. If signals are too low or clip
ping, adjust them at the source.
When set to post-fader, the meter is affected by the digital gain. It is not affected by the output analog gain setting.

Networking and Dante
Digital Audio Networking
Dante digital audio is carried over standard Ethernet and operates using standard internet protocols. Dante provides low laten
cy, tight clock synchronization, and high QualityofService (QoS) to provide reliable audio transport to a variety of Dante de
vices. Dante audio can coexist safely on the same network as IT and control data, or can be configured to use a dedicated net
work.
Switch and Cable Recommendations for Dante Networking
Switches and cables determine how well your audio network performs. Use highquality switches and cables to make your au
dio network more reliable.
Network switches should have:
Gigabit ports. 10/100 switches may work on small networks, but gigabit switches perform better.
Power over Ethernet (PoE) or PoE+ ports for any devices that require power
Management features to provide information about port speed, error counters, and bandwidth used
Ability to switch off Energy Efficient Ethernet (EEE). EEE (also known as "Green Ethernet") may cause audio dropouts and
problems with clock synchronization.
Diffserv (DSCP) Quality of Service (QoS) with strict priority and 4 queues
Ethernet cables should be:
Cat5e or better
Shielded
Compatibility with Dante Domain Manager
This device is compatible with Dante Domain Manager software (DDM). DDM is network management software with user au
thentication, role-based security, and auditing features for Dante networks and Dante-enabled products.
Considerations for Shure devices controlled by DDM:
When you add Shure devices to a Dante domain, set the local controller access to Read Write. Otherwise, you won't be
able to access to Dante settings, perform a factory reset, or update device firmware.

Shure Incorporated
18/23
•
•
•
•
•
•
If the device and DDM can't communicate over the network for any reason, you won't be able to control Dante settings,
perform a factory reset, or update device firmware. When the connection is reestablished, the device follows the policy set
for it in the Dante domain.
If Dante device lock is on, DDM is offline, or the configuration of the device is set to Prevent, some device settings are dis
abled. These include: Dante encryption, MXW association, AD4 Dante browse and Dante cue, and SCM820 linking.
See Dante Domain Manager's documentation for more information.
QoS (Quality of Service) Settings
QoS settings assign priorities to specific data packets on the network, ensuring reliable audio delivery on larger networks with
heavy traffic. This feature is available on most managed network switches. Although not required, assigning QoS settings is
recommended.
Note: Coordinate changes with the network administrator to avoid disrupting service.
To assign QoS values, open the switch interface and use the following table to assign Dante -associated queue values.
Assign the highest possible value (shown as 4 in this example) for time-critical PTP events
Use descending priority values for each remaining packet.
Dante QoS Priority Values
Priority Usage DSCP Label Hex Decimal Binary
High (4) Time-critical PTP
events CS7 0x38 56 111000
Medium (3) Audio, PTP EF 0x2E 46 101110
Low (2) (reserved) CS1 0x08 8 001000
None (1) Other traffic BestEffort 0x00 0 000000
Note: Switch management may vary by manufacturer and switch type. Consult the manufacturer's product guide for specific configuration details.

Dante Transmit Flows
This device supports up to two transmit flows and two receive flows. A single flow consists of up to four channels, through
either a unicast or multicast transmission.
A unicast flow is a point-to-point connection between two devices, supporting up to four channels per flow.
A multicast flow is a one-to-many transmission, which supports sending up to four channels to multiple receiving devices
across the network.
Shure Device Applications
This device can connect with up to two Dante devices.
The Shure MXA310, ANI22, ANIUSB-MATRIX and ANI4IN support multicast transmission. This means that flows can transmit
to multiple devices -- as many as the network can support. If using unicast flows, each of these devices can connect with up to
two Dante receiver devices.

The Shure ANI4OUT connects with up to two Dante transmitter devices.
Packet Bridge
Packet bridge enables an external controller to obtain IP information from the control interface of a Shure device. To access the
packet bridge, an external controller must send a query packet over unicast UDP* to port 2203 on the Dante interface of the
Shure device.
Send a UDP packet with a minimum 1-byte payload .
Note: The maximum accepted payload 140 bytes. Any content is allowed.
The Shure device will send a response packet over unicast UDP to the controller, using a destination UDP port identical
to the source port of the query packet. The payload of the response packet follows this format:
Bytes Content
0-3 IP address, as 32-bit unsigned integer in network order
4-7 Subnet mask, as 32bit unsigned integer in network or
der
8-13 MAC address, as array of 6 bytes
Note: The Shure device should respond in less than one second on a typical network. If there is no response, try sending the query again after verify
ing the destination IP address and port number.
