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.

⑤ Dante Network Port
Connects to a network switch to send Dante audio, while receiving Power over Ethernet (PoE) and data from the control software. See the Dante and networking section for additional information.
⑥ Reset Button
Resets the device settings back to the factory default.
This device requires PoE to operate. It is compatible with both Class 0 and Class 3 PoE sources.
Power over Ethernet is delivered in one of the following ways:
To identify the hardware by flashing the lights, select the Identify button in the device options section.
Two mounting solutions are available for installing the Audio Network Interface:
CRT1 19" Rack Tray (optional accessory): Supports up to 3 devices; mountable in a rack or under a table
Single-unit Mounting Tray (included accessory): Supports a single device for mounting under a table
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.
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.
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.
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:
To combine channels, select one of the summing options in
.Summing Option | Signal Destination |
---|---|
1 + 2 | |
Analog input 1 + analog input 2 | Dante output 1 |
Dante output 2 | |
3 + 4 | |
Dante input 1 + Dante input 2 | Analog output 1 |
Analog output 2 | |
1 + 2 / 3 + 4 | |
Analog input 1 + analog input 2 | Dante output 1 |
Dante output 2 | |
Dante input 1 + Dante input 2 | Analog output 1 |
Analog output 2 |
Levels for analog and Dante channels are adjustable in the Input tab.
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.
Source Level | Gain Range |
---|---|
Line (+4 dBu) | 0 to +9 dB |
Auxiliary (-10 dBV) | +9 to +21 dB |
Microphone (varies) | +21 to +51 dB |
Note: Leaving some additional headroom is a recommended to prevent clipping if mobile devices will be plugged into particular channels.
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.
Match the output level from the Network Interface to the input sensitivity on the analog device:
Each analog output channel has a corresponding LED:
Green: Audio signal present
Red: Audio signal is clipping and should be attenuated.
+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.
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.
Maximize audio quality by adjusting the frequency response with the parametric equalizer.
Common equalizer applications:
If you’re using Shure Designer software to configure your system, please check the Designer help section for more about this topic.
Adjust filter settings by manipulating the icons in the frequency response graph, or by entering numeric values. Disable a filter using the check-box next to the filter.
Filter Type
Only the first and last band have selectable filter types.
Parametric: Attenuates or boosts the signal within a customizable frequency range
Low Cut: Rolls off the audio signal below the selected frequency
Low Shelf: Attenuates or boosts the audio signal below the selected frequency
High Cut: Rolls off the audio signal above the selected frequency
High Shelf: Attenuates or boosts the audio signal above the selected frequency
Frequency
Select the center frequency of the filter to cut/boost
Gain

export to file: | Saves a preset file from the device onto a computer |
Mute sync ensures that all connected devices in a conferencing system mute or unmute at the same time and at the correct point in the signal path. Mute status is synchronized in the devices using logic signals or USB connections.
To use mute sync, make sure logic is enabled on all devices.
Designer's Optimize workflow configures all necessary mute sync settings for you.
Compatible Shure logic devices:
To use mute sync, connect a logic-enabled MX series microphone to an ANI4IN-BLOCK or ANI22-BLOCK.
Note: See microphone guides to learn how to turn on logic on mics.
For help with specific mute sync implementations, see our FAQs.
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.
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:
Important: For encryption to work, all Shure devices on your network must use encryption.
