Signal Flow and Connections

Connections and Signal Flow

Input: Dante Digital Audio

A single network cable delivers 4 channels of audio and Power over Ethernet (PoE). Use Dante Controller to route audio channels from the network to the network interface.

Output: Analog (4 XLR or Block Connectors)

Each output sends a discrete audio channel to connect to an analog device.

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

Signal routing between devices is managed through Dante Controller software, provided by Audinate™.

Summing

The Audio Network Interface provides channel summing to combine Dante signals from the network, and send them over a single analog output. This makes it possible to send all channels to a device with a limited amount of analog input 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.

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 computer.

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.

Important: 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:

CAUTION! 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.

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.

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:
  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

Event Log

The event log provides a detailed account of activity from the moment the device is powered on. The log collects up to 1,000 activity entries and time-stamps them relative to the last power cycle. The entries are stored in the internal memory, and are not cleared when the device is power-cycled. The Export feature creates a CSV (comma separated values) document to save and sort the log data.

Refer to the log file for details when troubleshooting or consulting with Shure Systems Support.

Levels and Metering

Adjusting Input levels

  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.

Adjusting Output Levels

Access the analog output levels through the web application, by selecting an output level from the Analog Gain (dB) pull-down menu. 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.

Note: the meters in the web application are not affected by the Analog Gain (dB) setting.

Pre- and Post-Fader Metering

There are two modes for monitoring so that both the input and output signals can be monitored separately.

When set to pre-fader, the meter displays the signal level from the source on the Dante network. If signals are too low or clipping, adjust them at the source.

When set to post-fader, the meter is affected by the digital gain. It is not affected by the output analog gain setting.

ANI22 Command Strings

This document can also be found at: http://shure.custhelp.com/app/answers/detail/a_id/6368

The device is connected via Ethernet to a control system, such as AMX, Crestron or Extron.

Connection: Ethernet (TCP/IP; select “Client” in the AMX/Crestron program)

Port: 2202

Conventions

The device has 4 types of strings:

GET

Finds the status of a parameter. After the AMX/Crestron sends a GET command, the ANI22 responds with a REPORT string

SET

Changes the status of a parameter. After the AMX/Crestron sends a SET command, the ANI22 will respond with a REPORT string to indicate the new value of the parameter.

REP

When the ANI22 receives a GET or SET command, it will reply with a REPORT command to indicate the status of the parameter. REPORT is also sent by the ANI22 when a parameter is changed on the ANI22 or through the GUI.

SAMPLE

Used for metering audio levels.

All messages sent and received are ASCII. Note that the level indicators and gain indicators are also in ASCII

Most parameters will send a REPORT command when they change. Thus, it is not necessary to constantly query parameters. The ANI22 will send a REPORT command when any of these parameters change.

Networking and Dante

Digital Audio Networking

Dantetm 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 Recommendations for Dante Networking

In addition to the basic networking requirements, Dante audio networks should use a Gigabit network switch or router with the following features:

  • Gigabit ports
  • Quality of Service (QoS) with 4 queues
  • Diffserv (DSCP) QoS, with strict priority
  • Recommended: A managed switch to provide detailed information about the operation of each network link (port speed, error counters, bandwidth used)

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.

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

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.
