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.

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
  3. Select that network and press Set to confirm the setting.

All connected microphones automatically update to the new network.

To update any other devices:

  1. Open the technician menu on the MXCW640 by tapping the gear icon, then tap the right side of the screen while holding down the volume control knobs.
  2. Go to the wireless tab.
  3. Depending on the Startup mode set on the unit, either scan for a network or view options in the list.
  4. Choose an access point network and press Connect .

To combine rooms again, simply change the conference units back to the original network to create the larger system.

Connected Network Name

The device displays the connected network from the toolbar.

Conference Unit Startup Mode

Set the Startup Mode to determine how MXCW conference units connect to the access point after powering on.

Access the technician menu on the conference unit by tapping the gear icon then tap on the right side of the screen while holding down both volume control knobs. Choose one of the following Startup Modes:

Last Connected (default) Automatically selects the network it was last connected to before powering down. New or factory default devices use this setting to access the SSID 00 by default.
List Manually choose from a prepopulated list of networks. To update the list with custom names, rename the SSID labels in the web application and push the list to the registered wireless devices.
Scan The device scans for available access point networks and ranks them with strongest signal at top, and weakest at the bottom. Manually select the network from the list.

Tip: When choosing the network manually, the list indicates the last connected access point with a star.

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 Wi-Fi 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 Avoidance

The access point has a built-in spectrum analyzer that continuously scans the Wi-Fi environment and ranks the best channels for operation. If interference is detected, the access point changes to a verified backup channel with minimal disruption to the audio performance.

Interference Avoidance for Regulated Wireless Channels

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 with priority devices, the access point has a built-in spectrum analyzer that continuously scans the wireless environment and ranks the best channels for operation. If interference is detected it will vacate the channel temporarily and change to a verified backup channel with minimal disruption to the audio performance. The channel turns grey in the web application to indicate it is unavailable. When the channel becomes available, 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 Wi-Fi systems are not causing interference:
    • Ensure at least 3 meters (10 feet) between access point and Wi-Fi routers, computers, or other active 2.4 GHz or 5 GHz sources.
    • Turn on typical Wi-Fi devices prior to the event so the MXCW system has time to select a clean channel.
    • Avoid heavy Wi-Fi 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.

Selecting the Country and Region (MXCWAPT-W only)

For the global MXCWAPT-W variation, set the operating region for the most reliable scans and to comply with local regulations. This is only required for the global MXCWAPT-W model variation.

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 limits: 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: Microphone button options 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 A spare, utility device for adding 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.

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.

Identifying a Device from the Software

Filter Only allow devices with these attributes to display in the devices table:
  • Speak priority
  • Audio groups
  • Left button functionality
  • Firmware version

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 simply swap (exchange) positions with the other seat.
    • To move multiple seats, click 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.

NFC Card Functionality

Use the free Shure NFC Card Programming application (available on 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 ( 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.

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 
  • 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.

Participant Microphone Control by Admin/Chairman

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.

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.

Managing Speakers from the Web Application

For increased control over the meeting, the chairman uses the web application to activate microphones. The chairman page is dedicated for controlling the speaker list and request queue. The chairman can manually turn on/off microphones, or simply monitor the list in automatic mode. Using the interface, the chairman can easily:

  • Click on a participant name to turn on the microphone, or add them to the request queue.
  • View who is speaking and who is waiting their turn to speak

There are three lists on the Chairman View page:

Active speakers List (Red) The speaker list displays the name and seat number of each active microphone. The list displays in chronological order, with the most recently activated microphone at the top of the list.
Requests (Green) Delegates in this list are next up for speaking. Primarily useful when operating in First In First Out mode (FIFO), the queue chronologically lists all participants that have pressed their speak button. Once an opening is available in the speak list, the participant at the top of the queue list is automatically turned on.
All participants This is a full list of meeting participants. Change seat names, sort the participant list, and move delegates to the Active speakers or Requests lists.

Controlling Participant Microphones

The following buttons are available to the chairman for controlling the microphones during a meeting:

Speak Instantly turns on a participant’s microphone. Select the icon next to the participant name to add them to the Speak list.
Request Add a participant to the request queue to put them in line for speaking. Select from any participant in the system, excluding the chairman.
All Delegates Off Turns off all participant units, leaving only the chairman in the speaker list.
Next On Activates the participant microphone at the top of the request queue. If the maximum speaker count has been reached, the new speaker replaces the last one on the list.
All Requests Off Removes all participants from the request queue.
Mute All Turns all participant microphones to mute without affecting the speaker list.

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 microphones. As participants turn on their microphones, they are added to these channels.Depending on your event, you may want to lower the limit on speakers or add chairman role to certain participants.

See Setting the Number of Active Speakers 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.

The automatic gain control is post-fader, and adjusts the channel level after the input level has been adjusted. Enable it on channels where the distance between the speaker and the microphone may vary, or in rooms where many different people will use the conferencing system.

Enable AGC in one of two ways:

  • Go to Audio > Active microphones and click on the AGC button.
  • Select the desired devices from the Devices tab and check the Enable AGC box.

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, an official's microphone unit can be recorded but kept private (taken out of the floor mix). Remove it from the floor mix and route it 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.
    1. Press Select source

    2. 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 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 used for language interpretation. In multilingual meetings, participants speak their native language into the microphone and listen to the interpretation on headphones.

Headphone Channels

Conference units include a headphone 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.

  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.

    • Floor Mix
    • Channel 1
    • Channel 2
    • Channel 3
    • Channel 4
    • Channel 5
    • Channel 6
    • Channel 7
    • Channel 8
  3. Adjust the volume of the headphones using the control knobs on the unit.

Set Up Interpretation Channels

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

  1. Go to Meeting Controls > Interpretation.
  2. Select the desired language from the dropdown.

  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.

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.

Dante Network Audio

Connect your Dante audio network to the MXCW system.

Connect a network of devices

10 input channels, useful for:

  • Dante-enabled microphones, such as Microflex®Advance™ Ceiling and Table Arrays
  • Output from an automatic mixer or room system
  • Videoconferencing signal of far-end audio

10 output channels, useful for:

  • Recording system for archiving
  • Live-streaming events
  • Videoconferencing feed of near-end audio

Routing Dante Channels

Use the free Dante Controller software by Audinate® to route Dante channels in and out of the MXCW system.

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

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 order
    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.

*UDP: User Datagram Protocol


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.
  • 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.


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

These protocols require multicast. Ensure multicast has been correctly configured for your network.


Restricting New Device Connections

The system allows any MXCW wireless microphones to connect to the SSID network and automatically join the audio system. But depending on the requirements of your application, you may want to configure the system to restrict connectivity.

These settings only affect additional devices not already present in the registered device list. Conference units already connected and registered are allowed to reconnect automatically.

To edit the network and audio connection of additional conference units, open the MXCW web application and go to Settings > Hardware.

  • Open: Allow new devices to connect to the access point network. Connected devices can be controlled and edited from the web application.
  • Closed: Prevent new devices from connecting to the access point network.


Registration is the final step that connects the conference unit to the MXCW audio system. By default, conference units automatically register once they are connected.

Automatic Additional devices automatically register to the access point (audio passing). This allows devices to quickly join the event without additional set up.
Manual Additional devices connect as unregistered (control but no audio). At any time, the administrator can register it from the Devices tab of the MXCW web application.

Unregistered devices

Saving Device Connection Settings

Power cycling the access point resets the audio and network connection settings. To remember your setting, set the connections to closed and manual before each power cycle.

Deregister a Device

To remove a device from registration:

  1. Go to the Devices tab.
  2. Find the desired device and select the box next to its icon.
  3. Open more options and press Deregister.
