①Analog Input with Logic
Connection (MX392)
In addition to running the audio signal, this boundary microphone features three additional
wire leads for logic connections. This allows the switch on the microphone to send a logic
mute signal to other equipment on the network, and to receive a logic LED control signal.
②Analog Input Sources Analog sources, such as wireless microphones, connect to the analog line input
③Analog Output Devices Loudspeakers, amplifiers, or recording devices connect to the analog line output
④ Dante-enabled Equip-
ment
Dante microphones, such as the Shure Microflex Advance ceiling and table arrays connect
to the network switch and can be routed using Dante Controller software.
⑤Control CPU A computer connected to the network accesses the web application to control the channel
levels and processing.
⑥Network Switch The network switch provides Power over Ethernet (PoE) to the ANI22, while also supporting
all other Dante-enabled audio equipment.
Summing
The Audio Network Interface provides channel summing to combine input signals and send them over a single output channel.
This makes it possible to send all channels to a device with a limited number of Dante receiver channels or analog inputs. The
relative channel levels are not affected; the mix is summed in the device and sent over a single output channel.
Note: When summing is enabled, a limiter is activated to prevent signal overloading. The limiter does not affect the direct outputs, and will only affect the
summed signal.
By default, the ANI22 treats signals this way:
Analog input 1 → Dante output 1
Analog input 2 → Dante output 2
Dante input 1 → Analog output 1
Dante input 2 → Analog output 2
To combine channels, select one of the summing options in Channels > Inputs.

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.
Logic Applications
The block connecter inputs feature three logic signal connections. Logic signals are converted into Ethernet command strings
and sent and received by any device (such as an echo canceller or control system) that supports Ethernet command strings.
In this diagram, Shure MX392 Microflex microphones are connected the audio network interface. The mute button on each mi
crophone sends a logic signal (switch) to mute other audio equipment. The microphones receive logic signals (LED) so that the
microphone LED behavior reflects the state of the entire audio system.

Device Identification
To identify the hardware by flashing the lights, select the Identify button in the device options section.
Audio Settings
Adjusting Input levels
Levels for analog and Dante channels are adjustable in the Input tab.
Dante Sources
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.
Analog Sources
Before you begin, verify that levels from the analog devices with adjustable output levels are operating at nominal levels. The
analog gain adjusts the level of the audio signal before it is converted from analog to digital. It is adjustable in 3 dB increments,
with up to 51 dB total gain.
Match the analog gain setting to the incoming signal level:
Source Level Gain Range
Line (+4 dBu) 0 to +9 dB

Shure Incorporated

2.
•
•
•
•
•
•
•
Source Level Gain Range
Auxiliary (-10 dBV) +9 to +21 dB
Microphone (varies) +21 to +51 dB
The meters should peak between -18 and -9 dB.
Note: Leaving some additional headroom is a recommended to prevent clipping if mobile devices will be plugged into particular channels.
Adjusting Output Levels
Dante Outputs
Output levels are controlled by the Digital Gain (dB) fader. Always adjust the input gain before the output gain. In most cases,
setting the analog gain correctly results in an appropriate output level. Sources that have a quiet signal, such as a microphone
with low sensitivity, may need some Digital Gain (dB) applied. If the output is clipping, use the Digital Gain (dB) fader to lower
the signal.
Note: If summing is enabled on input channels, use the Digital Gain (dB) and Analog Gain (dB) controls in the Input section to adjust the mix.
Analog Outputs
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.
Metering Options (Pre-gain and Post-gain)
Each Dante channel includes a meter to measure signal levels (dBFS), located in the web application under the input and out
put sections.
Pre-gain metering measures the signal level without digital gain applied. It does reflect analog gain adjustments on the two in
put channels. Post-gain metering measures the signal with both analog and digital gain applied.
To change the metering setting, open the Settings menu, select the General tab, and adjust the Metering setting.
Important: If the incoming signal is adjustable (wireless microphone systems, for example), make sure it is at the nominal level
before adjusting the analog gain on the Audio Network Interface.
Parametric Equalizer
Maximize audio quality by adjusting the frequency response with the parametric equalizer.
Common equalizer applications:
Improve speech intelligibility
Reduce noise from HVAC systems or video projectors
Reduce room irregularities
Adjust frequency response for reinforcement systems

Networking and Dante
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.
Pushing Device Names to the Dante Network
To send a device name to appear in Dante Controller, go to Settings>General and enter a Device Name. Select Push to Dante
to send the name to appear on the network.
Note: names appear in Dante Controller with "-d" attached.
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.
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.
