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.

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 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.

Levels and Metering

Adjusting Input Levels

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. Set the Metering to Pre-fader in the toolbar at the top of the workspace to monitor analog signal levels
2. Select the analog gain value to open the fader
3. Match the analog gain setting to the incoming signal level. Use the gain range markers on the fader to apply the appropriate amount of 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

4. 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

Output levels are controlled by the Digital Gain (dB) fader. Always adjust the input gain (analog) before the output gain (digital). 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 someDigital Gain (dB) applied. If adjustments to the Digital Gain (dB) fader are required, follow these steps:

1. Set the Metering to Post-fader in the toolbar at the top of the workspace.
2. Adjust theDigital Gain (dB) fader as needed.
3. If using summing, use the Digital Gain (dB) faders to mix the channel levels.

Metering Options (Pre-fader and Post-fader)

There are two modes for monitoring, for input and output signals to be monitored separately.

Pre-Fader (Analog Input Level)

Pre-fader metering displays the signal level before it reaches the digital gain fader, so that input signal levels can be optimized for each channel. Analog gain adjustments affect the meter when set to pre-fader, but the digital gain adjustments do not.

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.

Post-Fader (Digital Output Level)

Post-fader metering displays the signal level at the very end of the signal chain, which includes both the analog and digital gain. Use this setting to meter the levels that are being sent over the Dante network.

Mute Sync

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:

• P300 (Also mutes supported soft codecs connected by USB)
• ANIUSB-MATRIX (Also mutes supported soft codecs connected by USB)
• IntelliMix® Room software (Also mutes supported soft codecs connected by USB)
• MXA910
• MXA710
• MXA310
• Network Mute Button
• ANI22-BLOCK
• ANI4IN-BLOCK
• Logic-enabled MX microphones connected to ANI22-BLOCK or ANI4IN-BLOCK
  • MX392
  • MX395-LED
  • MX396
  • MX405/410/415

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.

Signal Flow and Connections

Setting up the Audio Network

Shure networked conferencing systems are comprised of Microflex Advance microphones and network interfaces, which operate entirely on a Dante network. Additional hardware, including network switches, computers, loudspeakers, and audio processors are described in the hardware component index.

Shure components shown in this diagram:

Microflex Advance Microphones

The MXA910 and MXA310 are equipped with Dante outputs, and connect directly to a network switch.

Audio Network Interfaces

The interfaces are used to connect analog devices such as loudspeakers and analog microphones to the network.

ANI4IN: Converts 4 analog signals (separate XLR and block connector models available) into Dante digital audio signals.

ANI4OUT: Converts 4 channels of Dante audio from the network into analog signals.

This diagram shows the entire signal path through a networked conference system. Signals from the near end and far end are exchanged through an audio processor connected to a phone system, or through a computer connected to the internet. Analog microphones connect to the network through the Shure ANI4IN, while loudspeakers connect through the Shure ANI4OUT.

This diagram shows Microflex Advance components in context, with two rooms communicating through video codecs.

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

You can manage signal routing with Dante Controller or Shure Designer software.

Connections and Signal Flow

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.

Parametric Equalizer

Maximize audio quality by adjusting the frequency response with the parametric equalizer.

Common equalizer applications:

• Improve speech clarity
• Reduce noise from HVAC systems or video projectors
• Reduce room irregularities
• Adjust frequency response for reinforcement systems

Setting Filter Parameters

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	Adjusts the level for a specific filter (+/- 30 dB)
Q Width	Adjusts the range of frequencies affected by the filter. As this value increases, the bandwidth becomes thinner.

Equalizer Applications

Conferencing room acoustics vary based on room size, shape, and construction materials. Use the guidelines in following table.

EQ Application	Suggested Settings
Treble boost for improved speech intelligibility	Add a high shelf filter to boost frequencies greater than 1 kHz by 3-6 dB
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: Set a narrow Q value 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 sibi lance Reduce the gain at the identified frequency (start be tween -3 and -6 dB) to minimize the unwanted room sound
Reduce hollow, resonant room sound	Identify the specific frequency range that "excites" the room: Set a narrow Q value 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 Reduce the gain at the identified frequency (start be tween -3 and -6 dB) to minimize the unwanted room sound

Software Installation, Management, and Security

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.

When components are connected through the Shure MXW Audio Network Interface, their firmware must be updated on one device at a time prior to updating the MXW Audio Network Interface firmware. Attempting to update all devices at once will cause the interface to reboot after its firmware is updated, and the connection to other networked components will be lost.

Perform the following steps to update the firmware:

Ensure the device has a stable network connection during the update. Do not turn off the device until the update is complete.

1. Connect the device and computer to the same network (set to the same subnet).
2. Download Shure Update Utility app and install it.
3. Open the application.
4. Click Check For Updates... button to view new firmware versions available for download.
5. Select the desired firmware and press Downloadto download it to the Firmware Library.
6. From the Update Devices tab, select the new firmware and press Send Updates... to begin the firmware update, which overwrites the existing firmware on the device.

Note: After updating, you may need to clear your browser's cache to display updates to the device's web application.

Firmware Release Requirements

All devices comprise a network with multiple communications protocols that work together to ensure proper operation. The recommended best practice is that all devices are on an identical release. To view the firmware version of each device on the network, open the component user interface, and look under Settings > About.

The format for Shure device's firmware is MAJOR.MINOR.PATCH. (Ex. 1.6.2 where 1 is the Major firmware level, 6 is the Minor firmware level, and 2 is the Patch firmware level.) At minimum, devices that operate on the same subnet should have identical MAJOR and MINOR release numbers.

• Devices of different MAJOR releases are not compatible.
• Differences in the PATCH firmware release level may introduce undesired inconsistencies.

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 Enable Encryption.
3. Enter a passphrase. All devices must use the same passphrase to establish an encrypted connection.

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.

Using Command Strings

This device receives logic commands over the network. Many parameters controlled through Designer can be controlled using a third-party control system, using the appropriate command string.

Common applications:

• Mute
• LED color and behavior
• Loading presets
• Adjusting levels

A complete list of command strings is available at: pubs.shure.com/command-strings/ANI4IN.

Logic Applications

The block connecter model variation (ANI4IN-BLOCK) features 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 and MX396 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.

Networking and Dante

Digital Audio Networking

Dante digital audio is carried over standard Ethernet and operates using standard internet protocols. Dante provides low latency, tight clock synchronization, and high Quality of Service (QoS) to provide reliable audio transport to a variety of Dante devices. Dante audio can coexist safely on the same network as IT and control data, or can be configured to use a dedicated network.

Switch and Cable Recommendations for Dante Networking

Switches and cables determine how well your audio network performs. Use high quality switches and cables to make your audio network more reliable.

Network switches should have:

• Gigabit ports. 10/100 switches may work on small networks, but gigabit switches perform better.
• Power over Ethernet (PoE) or PoE+ ports for any devices that require power
• Management features to provide information about port speed, error counters, and bandwidth used
• Ability to switch off Energy Efficient Ethernet (EEE). EEE (also known as "Green Ethernet") may cause audio dropouts and problems with clock synchronization.
• Diffserv (DSCP) Quality of Service (QoS) with strict priority and 4 queues

Ethernet cables should be:

• Cat5e or better
• Shielded

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.

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 Time-critical PTP	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.

Networking Terminology

PTP (Precision Time Protocol): Used to synchronize clocks on the network

DSCP (Differentiated Services Code Point): Standardized identification method for data used in layer 3 QoS prioritization

Packet Bridge

Packet bridge enables an external controller to obtain IP information from the control interface of a Shure device. To access the packet bridge, an external controller must send a query packet over unicast UDP* to port 2203 on the Dante interface of the Shure device.

1. Send a UDP packet with a minimum 1-byte payload. Note: The maximum accepted payload 140 bytes. Any content is allowed.
2. The Shure device will send a response packet over unicast UDP to the controller, using a destination UDP port identical to the source port of the query packet. The payload of the response packet follows this format:

   Bytes	Content
   0-3	IP address, as 32-bit unsigned integer in network order
   4-7	Subnet mask, as 32 bit unsigned integer in network or der
   8-13	MAC address, as array of 6 bytes

   Note: The Shure device should respond in less than one second on a typical network. If there is no response, try sending the query again after verifying the destination IP address and port number.
