General Description

The Shure Microflex® Complete Wireless (MXCW) system is a conferencing solution that provides a steady, reliable audio experience for up to 125 conference units. MXCW overcomes cable limitations for off-site meetings, flexible meeting rooms, or historic buildings where drilling holes in furniture is impractical. The system features automatic RF interference detection and avoidance technology, encrypted digital wireless transmission, and digital audio networking using Dante.

The MXCW access point has multiple mounting options for discreet communication between wireless conference units and the digital audio network, and works within the 2.4 GHz and 5 GHz frequency bands. Use the access point web application for system setup, and to monitor and control conference units. Conference units have configurable roles for meeting participants, and can be routed to the floor audio or an interpretation channel. Each wireless conference unit is powered by a smart lithium-ion rechargeable battery whose remaining charge can be checked remotely by a technician. The MXCW networked charging station charges and stores up to 10 Shure rechargeable batteries that can be monitored through its own web application.

Features

RF Efficiency Sound quality is consistent with one speaker or several, and up to 125 units are supported with just one access point transceiver and one RF channel.
Automatic Frequency Coordination The system automatically scans the available spectrum and selects clean transmission channels for best performance. Setting up the system is as easy as setting up a wireless router.
Interference Avoidance While in use, the system automatically moves away from unexpected interference. Channel adjustment protects against disruption to the audio.
Encryption Standard AES-128 encryption of audio and data keeps meeting content private.
Bi-Directional Wireless Provides return channels for interpretation audio to conference units and enables real-time remote control of conference unit settings.

System Set Up

Maximum System Size

Connect up to 125 MXCW wireless conference units to a single access point. Connected devices operate as a self-contained, encrypted audio system for speaking, listening, and contributing to the meeting.

Wireless Device Network

Setting up wireless MXCW devices is similar to connecting your computer to a wireless network. The MXCW access point acts as the wireless router, broadcasting a network SSID to the wireless devices in range.

The access point includes several customizable network SSIDs that allow you to label MXCW networks for easy recognition and control according to the installation or application. A default network (SSID 00) ensures that new or reset devices automatically connect after powering on.

To add a microphone, simply connect it to the right network.

Connecting Devices for the First Time

MXCW wireless devices automatically connect and register after power up. The default network SSID 00 ensures new or factory reset devices connect automatically to the access point in range.

To connect to an access point network:

  1. Power on the access point. Wait for it to automatically select the best available wireless channel for operation. When the channel is secured, the access point will broadcast its network (SSID 00) to the wireless MXCW devices.
  2. Power on the MXCW conference unit. The device automatically scans for the default network.

  3. The default access point network (SSID 00) is selected and the devices are ready for use.

  4. Add additional microphones until all participants are covered or the system is full.

Restricting New Device Connections

The devices tab in the web application shows which conference units are connected to the SSID network by separating them into 3 groups: online, offline, or unregistered. By default, conference units automatically register once they are connected.

You can add or remove devices from registration. Select a device, open more options, and press Deregister to move a device to the unregistered group. Select a device from the unregistered group, then open more options and press Register to register a unit.

To determine additional device connections, select one of the following options from the dropdown on the Devices tab:

  • Open (default): New devices will automatically connect and register.

  • Restricted: New devices will connect to the SSID network, but will be on the unregistered list until registered manually.

  • Private: No new devices can connect or register to the audio system.

Custom Network SSID Labels

It is recommended to change to a custom wireless network after getting up and running on the default network:

  • Recognizable: Provide distinct names for your installation. Useful names correlate to a room or common use of the system (examples: SSID=Training or SSID=3NW)
  • Security: Customs SSIDs are less likely to inadvertently connect unwanted wireless microphones.
  • Automatic Updates: All connected devices automatically update to match the new network label.

To customize the network SSID label:

  1. Go to  Settings > SSIDs.
  2. Select an SSID and rename it. Choose names (up to 32 characters) that make sense for your installation or use case.

    Note: The default SSID 00 is not editable.

  3. (Optional) Press Push to devices to update the static SSID list on all devices connected to this access point The device startup mode must be set to static list.

Resolving Identical Label Conflicts

If multiple access points share the same SSID and are in range of the devices, the system resolves the conflict by choosing one of the following:

  • Last connected access point based on its unique MAC address
  • Or if none are recognized, the access point with the strongest RF signal

Separating Networks for Multiple Systems

To create separate microphone systems, use multiple access points and set each one to a different SSID. Then connect the conference units to the corresponding network to set up the independent systems.

Multiple networks are useful for installations with adjacent meetings or divisible rooms that can be reconfigured depending on the size and needs of the event.

Divisible Room with Multiple System Options

Use different SSIDs to separate conference units into independent systems for smaller events. When the room opens up to support more participants, simply set all conference units to the same access point network to create a large system.

First, set an access point to a different SSID:

  1. Open the MXCW web application and go to Settings > SSIDs.
  2. (Optional) Rename one of the SSIDs network for easy identification, for example: Room C

Note: Anyone can access the web application from a computer or mobile device connected to the network when a passphrase is not enabled.

Wireless and RF Management

Microflex Complete Wireless provides automatic, encrypted wireless transmission for up to 125 conference units at a time. The access point scans and selects the best operating channel across the wireless 2.4 GHz and 5 GHz frequency bands, including DFS channels.

Wireless Operating Distance

The RF power level determines the operating distance between the access point and conference units. Set the RF power level according to the size of the microphone installation.

Variable Operating Distance

Setting RF Power

Select the RF power from the web application by going to Wireless > RF power.

RF Coverage from the Access Point
Setting Transmitter Power (mW) Coverage Distance from APT Typical Application
Maximum (default) 25 150 ft (45.7 m) Ballroom and auditorium spaces
High 13 100 ft (30.5 m) Large meeting spaces and lecture halls
Medium 5 50 ft (15.2 m) Conference, training and multipurpose rooms
Low 1 25 ft (7.6 m) Small video-conference rooms and boardrooms
Mute 0 0 ft (0 m) Long meeting breaks or access point not in use

Note: Maximum transmitter power varies by region.

Cardioid RF Pattern

The access point RF pattern is cardioid, picking up equally from the sides to the front cover of the unit.

Room Combining Example

Increase RF power levels to cover larger combined rooms.

Reliable Bandwidth Allocation

MXCW easily scales from 2 to 125 microphone units without any change in the audio performance. The bandwidth is strategically divided, allocating the uplink channels only for active speakers, while preserving traffic for continuous downlink monitoring channels.

Selecting or Excluding Specific Wireless Channels

You can avoid specific wireless channels by deselecting them from the web application. The MXCW system scans all channels in the 2.4 and 5 GHz spectrum and chooses the cleanest one for operation. After deselecting specific channels, MXCW will no longer scan and operate in those frequencies. At least one non-DFS channel must be selected at all times.

To exclude specific wireless channels:

  1. Go to the Wireless tab.
  2. Press Select wireless channels .
  3. Deselect the channels you do not want to use.
  4. Press Apply to save your changes.

Interference Detection and Avoidance

The access point has a built-in spectrum analyzer that continuously scans the wireless environment and ranks the best channels for operation. MXCW commonly operates in a specific block of 5 GHz channels that require Dynamic Frequency Selection (DFS) or Doppler weather radar Dynamic Frequency Selection (DDFS). These channels reserve priority for weather, aviation, and military devices.

To avoid interference from priority devices, DFS channels are scanned for 1 minute and DDFS channels are scanned for 10 minutes before the channels are available for use. If interference is detected, the access point changes to a verified backup channel with minimal disruption to the audio performance. Channels with detected interference are unavailable for 30 minutes. After 30 minutes, the system will resume scanning and verifying the channel for use.

Tips to Improve Wireless System Performance

If you encounter interference or dropouts, try the following suggestions:

  1. Check the installation of access point:
    • Ensure a clear line of sight between access point and the conference units.
    • Mount the access point near or above the microphone units
    • Make sure people do not block the line of sight between receiver and transmitter.
  2. Check that other wireless systems are not causing interference:
    • Ensure at least 3 meters (10 feet) between access point and wireless routers, computers, or other active 2.4 GHz or 5 GHz sources.
    • Turn on typical wireless devices prior to the event so the MXCW system has time to select a clean channel.
    • Avoid heavy wireless traffic activities on nearby networks such as downloading large files or viewing a movie.
  3. Additional tips:
    • Make sure the access point is using all available channels (reselect any channels that were manually deselected from the web application)
    • During sound check, mark trouble spots and position participants away from those areas.
    • Move access point and microphones away from metal or other dense materials.

Setting the Access Point Country and Region (MXCWAPT-B and MXCWAPT-W only)

For the MXCWAPT-B and global MXCWAPT-W model variations, the country and region must be set when the unit is powered on for the first time, or after a factory reset. Use the web application or the LCD menu to set the operating location for compliance with local regulations and to get the most reliable scans.

The MXCWAPT-B access point needs to be set to Canada or Mexico. The MXCWAPT-W access point needs to be set to one of the following countries and regions:

  1. Go to web application > Language and region and select a new country or region.
  2. Press Apply to save your changes.

    Note: After a change is applied, the access point will reboot and all connected devices will not be able to pass audio during this time. Refresh the browser for the web application after the access point has rebooted.

Setting Up Participants

Participant Roles

The system facilitates meetings in part by adjusting features and permissions based on the role assigned to each participant device. Participant roles affect:

  • Speaker limitations: The chairman can speak at any time, while delegates may need to wait their turn.
  • Speak priority: Participants can interrupt another active speaker depending on rank.
  • Hardware controls: Button functions depend on the role of the speaker.

    For example, since the chairman is responsible for the meeting, additional controls and permissions are granted to perform additional tasks and to speak at any time without waiting in line. Others are listeners and have minimal speaking permissions.

The following is a summary of the roles in the system:

Role Brief description Details
Chairman Moderator or leader of the event The chairman is a participant with additional permissions for controlling delegate microphones, accessing meeting controls, and overriding delegate speakers at any time.
Delegate Typical participant Delegates represent the majority of participants in a meeting. Depending on the microphone operation, delegates may need to wait in the request queue until it is their turn to speak.
Listener No microphone required Participants use the device only to listen to the floor mix (using the loudspeaker) or to an interpretation channel (using headphones). There are no speaking permissions in this role, but a chairman can turn on this microphone manually.
Ambient Improves audio mix This role is for spare, utility devices to add natural room ambient noise to the floor mix to aid during pauses in speech or brief breaks between agenda items when no other participants are on the speaker list. There are no listening or speaking permissions in this role.

Go to Meetings Controls > Advanced > Enable ambient microphones.

Remote Caller Delegates can remotely participate in events Connect a cell phone to a conference unit configured to the remote caller role. A remote caller occupies any of the 8 unassigned microphone slots, and remains on the speak list during the event.
Dual Delegate Two delegates share one conference unit Both the left and right buttons are configured as speak buttons, one for each participant. The speaker list shows both delegates as individual speakers, but only one uplink channel is being used by the shared microphone. Both delegates can cast votes.

Configuring Conference Units for Remote Callers

  1. Change a conference unit to the remote caller role in the technician menu or web application.
  2. Call the remote participant on a mobile device.
  3. Connect the mobile device to the TRRS jack on the back of the conference unit.

To allow conference units to automatically change to the remote caller role when connecting a mobile device, go to Meeting Controls > Basic and select Auto-sense remote caller role cable.

Speak Priority for Remote Callers

When a mobile device is connected to the conference unit, the remote caller will hear 1 of 3 tones that indicate their connection and speak priority:

  • 3 short ascending tones: Connected to the event and remains on the speak list.
  • 3 short descending tones: Connected and listening to the event, but no speaking permissions
  • 2 short repeating tones: Conference unit lost connectivity to the access point

Note: If the conference unit loses power, no tones are sent to the remote caller.

When a microphone slot becomes available, a remote caller can be added to the speak list by unplugging the cable from the conference unit and plugging it in again.

Changing the Participant Role

From the MXCW web application:

  1. Go to the Devices tab.
  2. Find and select the participant (or seat) in the list.
  3. Select the role to expand the dropdown and view additional roles.
  4. Select the role for that participant. The device reprograms with the corresponding controls and permissions.

Tip: To update multiple participants at once: select them and change the role from the side properties panel.

From the device technician menu:

  1. Enter the technician menu on the conference unit.
  2. From the role tab, select a new role.

To return to default settings, open more options and select Reset.

Assigning Names and Seat Numbers

The chairman and meeting operators will need to refer to the participants by either name, seat number, or both. The proper assignment of names and seat numbers is critical to ensure the continuity of the discussion.

When setting up the installation for the first time, each microphone unit appears with its default name and an automatically assigned seat number according to the order they were powered on. Use the Devices tab to match wireless devices to the anticipated seating chart.

Note: Devices already display the participant's name if an NFC card is inserted. See NFC Card Functionality for more details.

  1. Draw a seating chart, or diagram, that represents the room. Number each seat that requires a microphone. Add participant names to the seating chart.
  2. Provide seat names by clicking the seat name field and writing the new name for each unit.

  3. Reorder seats to match the actual seat numbers in the room or on your seating chart:
    • To move a single seat, click in the seat field for that row and enter the new number. If another seat already exists in that number, it will exchange positions with the other seat.
    • To move multiple seats, click more options > Push-to-renumber. Enable this mode to rearrange seats by pressing each device's speak buttons in the preferred order. This will remap devices according to the order the buttons are pressed.

Retain Seat Information

Device settings, such as seat name and seat number, are saved during a power cycle by default. To stop saving seat information click the save icon > Disable. Click the save icon > Retain to start saving seat information again.

NFC Card Functionality

Use the free Shure NFC Card Programming application (available on www.shure.com) to program NFC identification cards with the names of meeting participants.

The NFC Card Programming application is designed to work with ACOS3 dual interface or contactless cards, such as the MXCDualCard. Use the ACR1252U USB card programmer (www.acs.com.hk) to write participant names to the identification cards.

To allow NFC functionality for conference units:

  1. Go to Meeting Controls > Advanced > Enable NFC.
  2. Insert an NFC card into the conference unit so participants are identified by their name.

Note: NFC cards are not supported with dual delegate conference units.

Speak Priority

When speaker interruption is enabled, participants can override each other in the speaker list based on their speak priority and their role.

Manually adjust the speak priority of each participant to meet the needs of your meeting.

Example speak priority settings:

Multiple Chairmen
  • Set the highest-ranking chairman to 5
  • Set the rest of the chairmen to 4
High-Ranking Delegates
  • Leave the normal delegates at 1 (default)
  • Set the high-ranking delegates to 2

Adjusting Speak Priority

To adjust the speak priority without changing the participant's role:

  1. Open the web application to the Devices tab.
  2. Select the participant in the table to open the properties panel.
  3. Expand the additional properties and adjust the speak priority for that participant.

Active Speaker Interruption

When interruption is allowed, a participant that turns on their microphone will override the last person in the speaker list. The different modes determine the behavior of microphone activation when the speaker list is full.

To change the interruption mode:

  1. Go to Meeting Controls > Advanced > Active speaker interruption
  2. Select a mode:
  • Not allowed
  • Higher speak priority allowed (default)
  • Equal or higher speak priority allowed

See Speak Priority for information on adjusting individual participants' priority.

Microphone Activation Style

The speak mode determines the way the participants use their microphones in a group setting. Several factors may affect the meeting requirements and the manner in which the meeting is run: room size, number of participants, formality of the event, and amount of technical support on staff. The speak mode addresses these factors with presets to control the microphone behavior.

Mode Description How it Works
Automatic (default) Press to speak Speak button turns on participant microphone. There is no request queue: when the speaker list is full, the mic does not turn on.
FIFO (First in, first out) Automatic request queue Speak button adds participant to a queue system. Once the speaker list is full, participants are placed into a chronological request queue. The next microphone in queue turns on automatically once a space is open in the speaker list.
Manual Managed request queue Speak button adds the participant to a request queue that is managed by the chairman or operator.

Note: Speak priority may affect the list. A new speaker with higher priority may automatically override the earliest activated microphone if that speaker has a lower priority. See Speak Priority for more details.

Changing the Speak Mode

The speak mode is a system setting that applies to all conference units registered with the access point.

Use one of the following methods to change the speak mode:

  • Web application: Meeting Controls > Basic > Speak mode 

    Note: Chairmen can also change speak mode from the chairman view.

  • Access point LCD menu: Meeting Ctrls > Speak mode 

Setting the Number of Active Speakers

The MXCW system allows up to 8 active speakers. Once the speaker list is full, participants must wait until their turn to speak. If they attempt to speak before their turn, their microphone LED ring flashes momentarily and then turns off as a reminder.

To set the number of speakers:

  1. Go to Meeting Controls > Basic.
  2. Use the plus sign (+) and minus sign () to change the number of speakers.
    • Total: Total number of active delegate and chairman devices. This is the absolute maximum number of people that can address the floor at the same time.
    • Delegate: Number of delegate microphones that can be open at the same time (excludes the chairman).
    • Maximum Requests: Total number of participants that can be in the request queue. This is only available in Manual and FIFO mode.

Best Practices for Setting Active Speakers

  • Add an extra participant to the total number of speakers to allow a chairman to speak at any time.
  • When using First In, First Out (FIFO) mode, set the maximum number of speakers to 1 so the participants must wait to speak until another has finished.
  • Keep a microphone slot available for a remote caller.

Prevent Speak Button Conflicts

To prevent conflicts of a participant and an administrator or chairman attempting to perform the same action on a unit:

  1. Go to Meeting Controls > Advanced > Microphone off permissions.
  2. Select Prevent double-press of Speak button.
  3. Set the amount of time (in seconds) for a conference unit to register a second press.
  4. Optional: Allow a delegate to cancel the administrator or chairman's speak button press by holding the speak button down for an assigned duration between 1 - 120 seconds.

Changing Participant Microphone Off Permissions

To allow only the administrator or the chairman to turn off participant microphones:

  1. Go to Meeting Controls > Advanced > Microphone off permissions.
  2. Select Only admin/chairman can turn off participant microphones.

Audio Setup and Channel Routing

The MXCW system supports wireless, analog, and Dante™ network channels for a wide range of applications and installations. Use the web application to customize the audio system for your meeting.

MXCW Audio Channels

① MXCW Wireless Network Encrypted wireless audio between the access point and conference units:
  • 8 uplink channels for active speakers
  • 9 downlink listening channels (1 floor mix + 8 interpretation channels)
② Analog audio XLR connectors on the access point:
  • 1 input channel
  • 1 output channel
③ Dante network audio Digital audio channels over the Ethernet network:
  • 10 input channels
  • 10 output channels

Once the audio signal is added to the MXCW system, an internal matrix mixer routes audio signals between inputs and outputs, for simple and flexible routing:

  • Send the floor mix to multiple outputs for recording, broadcasting, and a spillover listening room.
  • Add an external sound source to the floor mix, such as a bodypack microphone for presenters.
  • Record each active microphone on a separate audio channel for official record keeping.

MXCW Routing Descriptions

MXCW Wireless Audio

Encrypted wireless audio between the access point and conference units:

Speaking Channels (Uplink) 8 uplink channels are provided for active speakers. As participants turn on their microphones, they are added to these channels.Depending on your event, you may want to lower the limit of speakers or add a chairman role to certain participants.

See Setting Up Participants for more information.

Up to 8 Speakers

Listening Channels (Downlink)
  • 1 fixed Floor channel on speaker and headphones
  • 8 assignable interpretation channels on headphone

Floor and Interpretation

The Floor Mix

Whenever a microphone is turned on, the audio is routed to the floor mix by default. The floor mix combines all active speakers and sends that signal to the other participant units for listening.

Listen to the floor mix on the unit loudspeaker or the headphone channel.

  • Loudspeakers: The floor mix is always the source for the loudspeakers
  • Headphones: The floor mix is also available on a headphone channel (Ch. 0)

Monitoring Active Microphones

Use the MXCW system web application to monitor and adjust the microphone slots for audio contributing to the floor mix. Go to Audio > Active microphones.

Analog Connections

Easily connect additional equipment using the XLR analog connectors on the MXCW access point. Common applications include adding a Q&A or presenter microphone, sending audio out to a broadcast feed, or connecting to a teleconferencing system.

Access Point Analog Connectors

Remove the cover to access the analog connectors

Connecting Analog Devices

  1. Connect a line-level audio device:
    • XLR input from a mixer or wireless receiver (default route to floor mix)
    • XLR output to a recording, loudspeaker, or teleconferencing system (default source is floor mix)
  2. Perform a sound check using normal speech levels with the rest of the MXCW microphones. For best results:
    • Always leave AGC enabled to make sure the signals blends naturally with other MXCW sources
    • Use the equalization filters to reduce unwanted sounds like HVAC.

Analog Input Example

Automatic Gain Control (AGC)

Automatic gain control adjusts channel levels to ensure consistent volume for all speakers, in all scenarios. For quieter voices, it increases gain; for louder voices, it attenuates the signal.

For best performance, it is recommended that AGC be enabled for all inputs. This means that all level adjustments will be made automatically by AGC and manual control of input levels using channel faders is inhibited.

If necessary, it is possible to override AGC functionality on a channel-by-channel basis. This may be accomplished by disabling the channel's AGC and then manually adjusting input level with the corresponding channel fader.

Enable or disable AGC in one of the following ways:

  • Go to Audio > Active microphones and click the AGC button.
  • Select the desired devices from the Devices tab and check the Enable AGC box.
  • For analog and Dante inputs, go to Audio > Inputs and click the AGC button.

Adding Other Sources to the Floor Mix

Add other audio sources to blend with the floor mix of MXCW wireless microphones.

  • 1 XLR analog input on the access point is automatically routed to the floor
  • 10 Dante digital network channels are selectable for routing
  1. Connect the audio source to the system:
    • Analog input: Connect an audio source to the XLR input on the access point.

      Tip: Flip the ground lift switch if a buzzing or humming sound occurs because of a ground loop.

    • Digital audio: Route audio to one of the MXCW Dante channels using Dante Controller software.
  2. Ensure the sources are selected on the floor group.

  3. If necessary, adjust the volume level or EQ to match the other input levels from Audio > Inputs.

    Tip: Always use AGC on each channel for automatic, continuous volume optimization.

Removing a Microphone from the Floor

By default, the audio from any active microphone is routed to the floor mix. However, you can remove a conference unit from the floor mix if you do not want it to go to the loudspeakers.

For example, a chairman's conference unit can be recorded but kept private (taken out of the floor mix). Remove it from the floor mix and route it to another group that is connected to a recording system for archival purposes.

  1. Go to Audio > Group mixes > Floor.
  2. Find the seat you want to remove and deselect it.

    Tip: Select Show connected seats only to filter out unoccupied seats.

  3. Route the audio from that seat to another group. Open the desired group and select the seat.

  4. Select that group as the source for the output channel.

    4a. Press Select source

    4b. Choose the group mix that the seat is routed to.

This group (with the seat that was removed from the floor mix) is now routed to the output channel and ready for recording, broadcasting, or another application.

Isolating Participants on Separate Output Channels

8 or Fewer Active Speakers

Assign each participant to their own group mix to record them individually on predetermined channels.

  1. Open the first group mix (A). Select the first seat. For easy reference, rename the group according that seat.

  2. Repeat for the rest of the group mixes (B - H).
  3. Open the Outputs tab.
  4. For the first Dante output channel, select Mix A for the input source.

  5. Repeat for the rest of the outputs.

More than 8 Active Speakers

To record more than 8 active speakers at a time, route the 8 microphone slots (instead of seats routed to mixes) to the output channels.

Keep in mind that the channels will not be permanently assigned to certain participants. The wireless 8 microphone slots 'fill up' starting with slot 1 and increasing with more active microphones. (Slot 1 is always filled whenever a microphone is active.) Therefore this method allows clean recordings, but the labeling will not follow the participants by seat.

  1. Set the number of active microphones and delegate microphones to 8 (maximum).
  2. Open the Outputs tab.
  3. For the first Dante output channel, select Microphone slot 1 for the input source.

  4. Repeat for the remaining microphone slots.

Emergency Audio Signal

To prepare for an emergency, connect an Emergency Evacuation Message (EEM) audio signal to the analog XLR input or one of the 10 Dante input channels. The system will detect when the EEM signal is present and distribute it to the loudspeakers and all output connections.

  1. Go to Audio > Inputs.
  2. Open the emergency audio dropdown menu and connect the EEM signal to a Dante channel (example: Dante input 1) or the XLR connector on the access point.

Note: Audio returns to normal after being below the threshold for 5 seconds.

Language Interpretation

There are 8 audio channels available for language interpretation. In multilingual meetings, participants speak their native language into the microphone and listen to the interpretation on headphones. Conference units configured to the remote caller role also have access to interpretation channels.

Set Up Interpretation Channels

Use the access point web application to set up interpretation channels for conference units.

  1. Go to Audio > Interpretation.
  2. Select the desired language from the dropdown menu.
  3. Press Assign Source and choose from the available analog input or 10 Dante inputs.
  4. Click the channel slider to turn the interpretation channel on.
  5. Repeat the above steps to create up to 8 interpretation channels.

Conference Unit Interpretation Channels

Conference units include a headphone and remote caller output for listening to interpreter channels or other participants on the floor channel. Each participant chooses their channel from the conference unit touchscreen.

Participants select one of the channels to listen to their language during a multilingual event. The audio source comes from the analog input or one of the Dante inputs.

The floor channel is used by interpreters to provide simultaneous interpretation of the discussion. This channel is also selectable by other participants to listen to the floor channel on headphones or in the remote call.

To select headphone channels:

  1. Connect headphones to a headphone jack on one of the sides of the conference unit.
  2. Press the headphone icon on the touchscreen and select a channel from the list.
  3. Adjust the volume of the headphones using the control knobs on the unit.

To select remote caller channels:

  1. Connect a mobile device to the TRRS jack on the back of the conference unit.
  2. Press the phone icon on the touchscreen and select a channel from the list.

  • 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 Network Audio 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.

To activate encryption:

  1. Open the Settings menu and select Encryption.
  2. Click Enable Encryption.

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.

Networking

Networking Best Practices

Use the following best practices when setting up a network to ensure reliable communication:

  • Always use a "star" network topology by connecting each component directly to the switch or router.
  • Connect all Shure networked devices to the same network and set to the same subnet. This applies to all devices that audio signals must be routed between (managed through Dante Controller). It is also required in order to open the web application for a device.
  • Devices on separate networks require an audio processor or conferencing software to carry audio between them.
  • Use only 1 DHCP server per network. Disable DHCP addressing on additional servers.
  • Power on the switch and DHCP server prior to MXCW equipment.
  • To expand the network, use multiple Ethernet switches in a star topology.
  • All devices must be at the same firmware revision level.

Device IP Settings

Configure IP

Sets IP mode of the selected network interface:

  • Auto (DHCP): For automatic assignment of IP addresses.
  • Manual (Static): For Static IP addresses.

IP Settings

View and edit the IP Address, Subnet Mask, and Gateway for each network interface.

MAC Address

The network interface's unique identification.

Configuring IP Settings

IP configurations are managed through the web application or the access point LCD screen. By default, they are set to Automatic (DHCP) mode. DHCP mode enables the devices to accept IP settings from a DHCP server, or automatically fall back to Link-Local settings when no DHCP is available. IP addresses may also be manually set.

To configure the IP properties in the web application:

  1. Open the web application.
  2. Go to Settings and select Network.
  3. Select Automatic or Manual. If Automatic is used, addresses will be automatically assigned. See Manually Assigning Static IP Address for Manual setup.

Manually Assigning Static IP Address

To manually assign IP addresses:

  1. Open the web application.
  2. Go to the Settings tab and select Network.
  3. Select Manual as the IP configuration.
  4. Enter the IP address, Subnet mask, and Gateway address.
  5. Click Apply when finished.

Setting Latency

Latency is the amount of time for a signal to travel across the system to the outputs of a device. To account for variances in latency time between devices and channels, Dante has a predetermined selection of latency settings. When the same setting is selected, it ensures that all Dante devices on the network are in sync.

These latency values should be used as a starting point. To determine the exact latency to use for your setup, deploy the setup, send Dante audio between your devices, and measure the actual latency in your system using Audinate's Dante Controller software. Then round up to the nearest latency setting available, and use that one.

Use Audinate's Dante Controller software to change latency settings.

Latency Recommendations

Latency Setting Maximum Number of Switches
0.25 ms 3
0.5 ms (default) 5
1 ms 10
2 ms 10+

Using the Web Application with a Wireless Connection

When operating the web application with a wireless connection, it’s important to set up the wireless router properly for best performance. The system employs several standard-based protocols that rely on multicast. The wireless connection treats broadcast and multicast packets differently than general packets for backward compatibility reasons. In some cases, the wireless router will limit the multicast packet transmission rate to a value that is too slow for web application to properly operate.

Wireless routers typically support 802.11b, 802.11a/g, and/or 802.11n standards. By default, many wireless routers are configured to allow older 802.11b devices to operate over the network. In this configuration, these routers will automatically limit the multicast data rates (or sometimes referred to as ‘basic rate’, or ‘management rate’) to 1-2Mbps.

Note: A wireless connection can only be used for the control software. Network audio cannot be transmitted over a wireless connection.

Tip: For larger wireless microphone configurations, it’s recommended to increase the multicast transmission rate to provide adequate bandwidth.

Important: For best performance, use a wireless router that does not limit the multicast rate to 1-2 Mbps.

Shure recommends the following wireless router brands:

  • Cisco
  • Linksys
  • Apple

AES67

AES67 is a networked audio standard that enables communication between hardware components which use different IP audio technologies. This Shure device supports AES67 for increased compatibility within networked systems for live sound, integrated installations, and broadcast applications.

The following information is critical when transmitting or receiving AES67 signals:

  • Update Dante Controller software to the newest available version to ensure the AES67 configuration tab appears.
  • Before turning encryption on or off in the Shure device’s web application, you must disable AES67 in Dante Controller.
  • AES67 cannot operate when the transmit and receive devices both support Dante.
    Shure Device Supports: Device 2 Supports: AES67 Compatibility
    Dante and AES67 Dante and AES67 No. Must use Dante.
    Dante and AES67 AES67 without Dante. Any other audio networking protocol is acceptable. Yes

Separate Dante and AES67 flows can operate simultaneously. The total number of flows is determined by the maximum flow limit of the device.

Sending Audio from a Shure Device

All AES67 configuration is managed in Dante Controller software. For more information, refer to the Dante Controller user guide.

  1. Open the Shure transmitting device in Dante Controller.
  2. Enable AES67.
  3. Reboot the Shure device.
  4. Create AES67 flows according to the instructions in the Dante Controller user guide.

Receiving Audio from a Device Using a Different Audio Network Protocol

Third-party devices: When the hardware supports SAP, flows are identified in the routing software that the device uses. Otherwise, to receive an AES67 flow, the AES67 session ID and IP address are required.

Shure devices: The transmitting device must support SAP. In Dante Controller, a transmit device (appears as an IP address) can be routed like any other Dante device.

System Maintenance and Troubleshooting

Troubleshooting

Basic System Check

Check your system for the following basic hardware and connections:
