General Description

The Shure ANI22 Audio Network Interface provides 2 channels of Dante-to-analog and 2 channels of analog-to-Dante conversion. A single interface provides a simple way to connect analog equipment to the audio network, such as wireless microphones, audio processors, video codecs, and loudspeaker systems. Available in XLR and block connector versions, each box uses a single network cable to carry audio and power through Power over Ethernet (PoE). A browser-based web application controls audio and network settings from any computer connected to the same network.

Hardware and Installation


Block Connector Model:

XLR Model:

① Signal/Clip Indicators

Each indicator corresponds to a single channel. Analog and digital gain adjustments are made through the web application.

  • If an input channel LED turns red, attenuate the level from the source device to prevent clipping at the input stage.
  • If an output channel LED turns red, lower the corresponding Digital Gain (dB) fader for the Dante channel under the Input Channels tab. Do not lower the output level (line/aux/mic), as any clipping indicated on the LED occurs before the final output level stage.

Single-unit Mounting Tray (included accessory): Supports a single device for mounting under a table

Securing the Devices

Use the included screws from the mounting hardware kit to secure the Audio Network Interfaces. Audio Network Interfaces can be mounted to face either direction. Insert the screws from the bottom in the appropriate holes, according to the following diagrams:

Align the holes as shown for securing a single device in the single-unit mounting tray

Align the holes as shown for securing up to 3 devices in the 19" rack tray.

Rack Ear Configuration

A combination of up to 3 Audio Network Interfaces can be mounted in a single 19-inch rack space. The adjustable rack ears support mounting in a standard equipment rack or underneath a table.

Standard 19" Rack Mount

  1. Align the ears with the mounting holes pointed forward.
  2. Install the 3 screws that hold the ear to the tray as shown.

Under-Table Mounting

  1. Align the ears with the mounting holes pointed upward.
  2. Install the 3 screws that hold the ear to the tray as shown.

Installing Underneath a Table

  1. Hold the tray in the desired location under a table.
  2. Use a pencil to mark the location of the mounting holes on the table.
  3. Drill 4 holes for the screws. The diameter of the holes in the tray are 7.1 mm.
  4. Install the components into the tray.
  5. Install with 4 screws to secure the tray underneath the table.


The reset button is located inside a small hole in the rear panel. Use a paperclip or other small tool to press the button.

There are two hardware reset functions:

Network reset (press button for 4-8 seconds)

Resets all Shure control and audio network IP settings to factory defaults

Full factory reset (press button for longer than 8 seconds)

Restores all network and Designer settings to the factory defaults.

Software Reset Options

To simply revert settings without a complete hardware reset, use one of the following options:

Reboot Device:Power-cycles the device as if it were unplugged from the network. All settings are retained when the device is rebooted.

Default Settings: To revert audio settings back to the factory configuration (excluding Device Name, IP Settings, and Passwords), select Load Preset and choose the default settings preset.


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.

Dante input 1 + Dante input 2 Analog output 1
Analog output 2

Adjusting Input levels

Levels for analog and Dante channels are adjustable in the Input tab.

Dante Sources

  1. 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.
  2. 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.

  1. Match the analog gain setting to the incoming signal level:
    Source Level Gain Range
    Line (+4 dBu) 0 to +9 dB
    Auxiliary (-10 dBV) +9 to +21 dB
    Microphone (varies) +21 to +51 dB
  2. 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.

Audio Settings

Channel Utilities

+48V (Phantom Power)

Delivers + 48V phantom power to the selected channel

Polarity Reverse

Each Dante channel has a checkbox to reverse the polarity of the input signal.

Analog Gain

Adjusts the gain to optimize input signal level before the analog audio is converted to a digital audio.

Digital Gain

Adjusts the digital signal level to optimize the signal strength over the network.

Mute Groups

Check the Mute group box to add the channel to a group. Muting any channel within the Mute group mutes all channels in the group.

Fader Groups

Check the Fader group box to add the channel to a group. All faders within the group are linked, and move together when a single fader is adjusted.

Logic Switch Indicator

Illuminates when a switch logic signal is received by the Audio Network Interface from a microphone.

Note: only applies to block connector model.

Logic LED Indicator

Illuminates when an LED logic signal is received by the Audio Network Interface through the network from a control system.

Note: only applies to block connector model.

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 output sections.

Pre-gain metering measures the signal level without digital gain applied. It does reflect analog gain adjustments on the two input 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

If you’re using Shure Designer software to configure your system, please check the Designer help section for more about this topic.

HVAC noise reduction Add a low cut filter to attenuate frequencies below 200 Hz
Reduce flutter echoes and sibilance Identify the specific frequency range that "excites" the room:
  1. Set a narrow Q value
  2. Increase the gain to between +10 and +15 dB, and then experiment with frequencies between 1 kHz and 6 kHz to pinpoint the range of flutter echoes or sibilance
  3. Reduce the gain at the identified frequency (start between -3 and -6 dB) to minimize the unwanted room sound
Reduce hollow, resonant room sound Identify the specific frequency range that "excites" the room:
  1. Set a narrow Q value.
  2. Increase the gain to between +10 and +15 dB, and then experiment with frequencies between 300 Hz and 900 Hz to pinpoint the resonant frequency.
  3. Reduce the gain at the identified frequency (start between -3 and -6 dB) to minimize the unwanted room sound.

Custom Presets

Use presets to quickly save and recall settings. Up to 10 presets can be stored on each device to match various seating arrangements. A preset saves all device settings except for the Device Name, IP Settings, and Passwords. Importing and exporting presets into new installations saves time and improves workflow. When a preset is selected, the name displays above the preset menu. If changes are made, an asterisk appears next to the name.

Note: Use the default settings preset to revert to the factory configuration (excludes Device Name, IP Settings, and Passwords).

Connections and Signal Flow

Illustration of the different devices that can be connected to Shure's ANI22 processors: wireless mics, Dante mics, loudspeakers, and others.

① Analog 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.

② Analog Input Sources

Analog sources, such as wireless microphones, connect to the analog input

③ Analog Output Devices

Loudspeakers, amplifiers, or recording devices connect to the analog line output

④ Dante-enabled Equipment

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.

⑤ Control CPU

A computer connected to the network accesses the web application to control the channel levels and processing.

⑥ Network Switch

The network switch provides Power over Ethernet (PoE) to the ANI22, while also supporting all other Dante-enabled audio equipment.

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 microphone 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.


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:

  1. Open the Settings menu and select the General tab.
  2. Select Enable Encryption.
  3. 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.

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 authentication, 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 disabled. 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.
