ɣ 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.
ɤ Control CPU A computer connected to the network accesses the web
application to control the channel levels and processing.
ɥ Network 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 amount 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 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.
Logic Applications

9/12/17, 9(22 AMShure Publications | User Guides | ANI22
Page 14 of 35http://pubs.shure.com/guide/ANI22/en-US
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.
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:
1. Open the Settings menu and select the General tab.
2. Select the Enable Encryption checkbox.
3. Enter a passphrase. All devices must use the same passphrase to establish an
encrypted connection.
Important: For encryption to work:
Encryption must be universally enabled or disabled on all connected Shure devices
AES67 must be disabled in Dante Controller to turn encryption on or off. AES67
encryption is currently not supported.
Device Identification
To identify the hardware by flashing the lights, select the Identify button in the device
options section.
Using A Password
All settings are configurable by default. To protect settings with a password, open the

9/12/17, 9(22 AMShure Publications | User Guides | ANI22
Page 15 of 35http://pubs.shure.com/guide/ANI22/en-US
Settings menu and select the General tab. In this screen, passwords can be created or
changed.
Once a password has been set, a Read-Only option appears on the log-in screen. In Read-
Only mode, device parameters can be viewed, but not edited. Device identification
remains active.
Audio Settings
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

9/12/17, 9(22 AMShure Publications | User Guides | ANI22
Page 16 of 35http://pubs.shure.com/guide/ANI22/en-US
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 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
