Shure ANI4IN Series User manual

Overview
General Description
The Shure ANI4IN Audio Network Interface converts 4 analog audio channels
into independent digital audio channels on a Dante™ network. Microphone,
auxiliary, and line-level devices are supported, with adjustable gain and +48V
phantom power for each channel. In networked conferencing systems, the
Audio Network Interface provides a simple way to connect analog equipment
onto the audio network, such as wireless microphones. The web application
controls signal routing and channel settings from any computer connected
to the same network.
Model Variations
ANI4IN-XLR: Four XLR inputs (balanced audio only)
ANI4IN-BLOCK: Four 6-pin block connector inputs (balanced audio and
logic connections)

Reset
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 web application 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:In the web application (settings > factory reset), there is a Reboot Device button, which simply 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.

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, adjusting loudspeaker volume or muting a wired microphone, which
would normally be done from the hardware, can now be controlled remotely over the network.
Dante™ Signal Routing
Signal routing between devices is managed through Dante Controller software, provided by Audinate™ .

① MX396 ② MX392
③ ULX-D Receiver ④ Network Switch
⑤ Computer
① MX396 (Dual-element)
In addition to running the audio signals, 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 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.
③ ULX-D Receiver
Wireless microphones connect to the network interface through the balanced analog outputs on the receiver.
④ Network Switch
Provides connectivity between the Dante™ audio network and the computer that controls signal processing and routing.
⑤ Computer
A computer or tablet running the web application provides independent gain control for each connected device.
Input: Analog (4 XLR or Block Connectors)
Each Audio Network Interface has 4 analog inputs with variable analog gain for line, auxiliary, and microphone-level signals. Examples of devices to connect to
the network with the Audio Network Interface:
• Wireless microphone systems
• Wired installed microphones (logic functions supported by block connector model)
• Computers or mobile devices used for presentations
• Other playback devices
Output: Dante™ Digital Audio
Connect the Dante™ output to a network switch with a network cable. A single network cable delivers all 4 channels of audio onto the network, and carries
Power over Ethernet (PoE) to power the device. Use Dante™ Controller to route audio channels from the Audio Network Interface to the appropriate network
destination. Any of the signals may be routed to multiple destinations, to provide local reinforcement while simultaneously delivering audio to the far end.
Summing
The Audio Network Interface provides channel summing to combine input signals and send them over a single Dante™ channel. This makes it possible to send
all channels to a device with a limited amount of Dante™ receiver 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.

Example Scenario
A common application that requires summing is a video conference where there are multiple microphones. When a device (a computer running conferencing
software and Dante™ Virtual Soundcard, for example) only supports 1 or 2 Dante™ receiver channels, the Audio Network Interface combines the input signals
to transmit as a single Dante™ channel.

① Summed analog audio channels
When the 4 analog audio channels are summed, each of the Dante™ transmit channels includes all of the input signals.
② Single Dante audio channel
One Dante™ signal is sent over the network, which contains all 4 summed channels.
③ Connection to computer
A computer that is running limited number of Dante™ channels with Dante™ Virtual Soundcard, receives all audio on a single channel. This audio is sent to
the far end.

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.
Software Installation, Management, and Security
Software Installation and Device Discovery
The Shure Web Device Discovery application is used to access the web application for a Shure device. The web application opens in a web browser to provide
comprehensive device management. Any computer networked to the device can access the GUI with this application.
Compatible Browsers:
• Chrome
• Safari
• Firefox
• Internet Explorer
1. Install the Shure device discovery application, available at www.shure.com
2. Double-click the component to open the interface.
Accessing the Web Application
The Shure Web Server Discovery application finds all Shure devices on the network that feature a web-based GUI. Follow these steps to install the software
and access the web application:
① Install the Shure Discovery application
Download and install the Shure Discovery application from www.shure.com. This automatically installs the required Bonjour device discovery tool on the com-
puter.
② Connect the network
Ensure the computer and the hardware are on the same network.
③ Launch the Discovery application
The app displays all Shure devices that feature a GUI.
④ Identify the hardware
Double-click on a device to open its GUI in a web browser.
⑤ Bookmark the device's web application (recommended)
Bookmark the device's DNS name to access the GUI without the Shure Discovery app.
Accessing the Web Application without the Discovery App
If the Discovery application is not installed, the web application can be accessed by typing the DNS name into an internet browser. The DNS name is derived
from model of the unit, in combination with the last three bytes (six digits) of the MAC address, 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 developed 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.
