Power, control data, and audio are transported from one unit to the next over the same shielded Cat5e cable.
To protect the equipment, ensure that the central control unit (CCU) is always off when connecting or disconnecting the conference units. Use any of the four chain connectors (A, B, C, and/or D) for connecting DCS-LAN components.
- Power off the CCU to protect the equipment during set up.
- Connect a chain output on the CCU to the first conference unit with the shielded Cat5e cable.
- Connect the rest of the conference units in sequence, using the RJ45 jacks on the bottom of each unit.
- Use the included cable clamp to secure the cables in place.
- Turn on the CCU by pressing the power button. The conference units will power on. The unit is stable once the control button LEDs stop flashing.
Warning: Do not turn off CCU power until the system has stabilized

When a microphone is turned on, the audio is routed to the main mix (Group A) and headphone output (Channel 0) by default. This mix is often referred to as the 'floor' mix, because it transmits the audio from the speaker to the rest of the participants in the meeting.
The number of allowed open microphones can be set at the CCU. The sound from all the open microphones is combined in the floor mix. The floor mix can be listened to on connected conference units and interpreter consoles, or sent to an external PA system.
Route Microphones to Groups
By default, the floor mix is routed to the loudspeaker and headphone output (Channel 0) of each connected conference unit. Go to the Group Setup page (
) to view or modify the microphone routing.
The following routing options are available for each microphone (seat):
- Group A only (default)
- Group A + another group
- Group B, C, D, E, F, G, or H
To change the audio source:
- Route microphones to Group A to add them to the floor mix (selected by default):
- Select the audio sources for the loudspeaker and Channel 0 (headphone):
- Floor (default)
- Audio In 1
- Audio In 2
Floor Mix on the Loudspeakers
Loudspeakers are included in most conference units for localized sound-reinforcement of the meeting. When a participant uses their microphone, their speech is heard in the loudspeakers of the other units in the system. This improves speech clarity in large rooms and reduces typical problems associated with sound reinforcement systems.
Note: To avoid feedback, the loudspeaker in a unit is turned off when the microphone is active.
Loudspeaker volume is a system setting that applies to all connected units. Volume is adjustable from -0 dB (no attenuation) to -40 dB, including off (mute). To adjust the volume:

- Adjust the volume at the audio source to mix naturally with speech levels of the conference units.
Input Control Page
Emergency Audio Signal
To prepare for an emergency, connect an Emergency Evacuation Message (EEM) audio signal to Input 2. The block connector provides a 'normally-open' switch that when closed, distributes the emergency signal to the loudspeakers and all input and output connections.
Important: When the switch is used for Input 2, the EEM audio signal bypasses the volume and on/off settings. Control the volume of the EEM signal at the source output.
- Connect the EEM signal to Input 2.
- Connect a switch to the block connector.
- Close the switch and test the audio signal. Adjust the volume at the audio source to the desired level.
Names, Roles and Seat Numbers
When a meeting begins, the chairman or moderator 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 meeting.
Assigning Seat Numbers
Each conference unit is automatically assigned a seat number when the system is turned on for the first time, or when a new conference unit is connected. To update seat numbers according to a seating chart:
- Go to
- Make sure all units are connected and functioning, indicated by the serial number and seat number in the list.
Note: Disconnected units can be removed from the list by selecting Remove Unregistered Units.
- Reassign seat numbers to match the actual seat numbers in the room or on your seating chart.
- Match the entries in the seat table to the corresponding units in the room by clicking in the seat number field. The light ring on the microphone flashes red to confirm your selection.
- Type a new seat number, or use the up/down arrows to re-arrange the seats in the list. Entering a seat number used by another conference unit swaps the seat numbers between units.
The Type column refers to the unity type. If a conference unit is configurable as a dual unit, a dropdown is available to make the selection. Changing the unit type from single to dual restarts the conference unit. The original entry is removed and two new entries with new seat numbers are created when the page information refreshes.
Assigning Names and Roles
MXC conference units can support Chairman or Delegate roles for meeting participants. Roles are set manually in the
The default speak priority is 1. Chairman units have a speak priority of 5.
Setting the speak priority to 0 disables speaking privileges for the unit, while still allowing listening and voting, but the microphone can be turned on by a chairman.
The Participant name can also be modified on this screen. By default, this is populated with the seat number (Seat 1, Seat 2, etc.). Manually update the Participant name field for each seat, or click Reset all names to reset to the default values.
If Use card data is set to On, the MXC system pulls participant information from the NFC card, if applicable. When the card is removed, the information reverts to the values set in the web app.
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. Adjust these settings in the CCU to best fit the meeting needs:
Speak mode: how participants are allowed to address the floor
Reply functionality: briefly comment to the current speaker without altering the request queue
Number of simultaneous speakers: control the discourse by limiting the number of speakers at once
Microphone override (Interrupt mode): behavior of the microphone activation when the speaker list is full
The “Speak mode” determines the behavior of the microphone system.
Auto (Automatic) mode allows for conference units to be immediately toggled on or off by pushing the Speak button.
Manual mode features a Request list. The Speak button adds delegates to the request queue. Pushing the button a second time cancels the request.
In Manual mode, the conference unit microphone can only be turned on remotely, either from the CCU web app, from SW6000, or from a third-party control system, but can be turned off using the Speak button.
FIFO (First In, First Out) is an automated mode featuring both immediate activation and a Request list. A meeting administrator sets a maximum number of speakers and requests. Pushing the Speak button activates the delegate's microphone immediately, until the maximum number of delegate speakers is reached, at which point delegates are placed in the request queue until the maximum requests is reached.
When an active unit is switched off, the first unit in the queue turns on automatically. The Request indicator flashes when the conference unit is at the top of the queue and is the next to be switched on.
VOX (voice activation) mode allows conference units to be switched on automatically when a delegate is speaking in the microphone, as well as toggled on or off using the Speak button. The microphone also turns off automatically after 4 seconds.
Dual units do not support VOX. If VOX is selected, a dual unit will operate in Auto mode. Chairman units are always in Auto or VOX mode.
Note: VOX is available in legacy DCS units, and support for MXC is planned for a future firmware update.
Speak Interrupt Ability
The Speak interrupt ability setting determines when a participant can interrupt (turn off) other active speakers by turning on their own microphone, if the number of active microphones reaches the limits set under Max. speakers: Delegates and Max. speakers: Total.
Individual priority settings can be manually determined in the Speak priority column under .
Speak Button Lock
When controlling microphones remotely, the Speak button can be temporarily disabled to avoid unintentional activation by the delegate.
Speak button lock is Off by default. When turned On, only units/users with speak priority 0-4 are locked. Remote commands from TCP/IP, SW6000, and units with microphone control permission are not affected.
Lock duration is the amount of time the button's toggle functionality is affected.
- Ranges from 2 to 120 seconds, in 1-second intervals
- After this time, functionality returns to normal
Lock override time is the amount of time (in seconds) that the Speak button must be held for the speaker to bypass the lock.
- Ranges from 1 to 120 seconds, in 1-second intervals
- Can never be longer than the Lock duration time
Allow Mic Off
This determines whether a delegate can turn his or her microphone off. The option defaults to Allowed.
When set to Not allowed, only a participant with microphone control permission (Chairman) can turn off the microphone.
The setting is available in the Auto, Auto + Reply, Manual and Manual + Reply modes, and only applies to units/users with speak priority 0-4.
Mute Button Behavior
Toggle: Pushing the Mute button on a conference unit mutes the microphone. Pushing the button again un-mutes the microphone.
Press and hold: Pushing the Mute button mutes the microphone. Releasing the button un-mutes the microphone.
The reply mode enables participants to briefly comment or ask a question to the present speaker. This allows a concise follow-up to the speaker without affecting the request queue.
On the participant's conference unit, the left (function) button can be programmed to operate as a Reply button. MXC640 conference units can also have the Reply button assigned to the touchscreen. The participant presses the Reply button to add themselves to the Reply list (shown above the Request list), and the chairman or operator manually activates the reply. Participants on the Request list can be added to the Reply list, but participants on the Speak list cannot.
The Reply option is available in Manual, Automatic and VOX modes. In Manual mode, the reply list is cleared when the next request is turned on.
Replies are sorted by the order in which they are received. If multiple reply options are used, replies are sorted by priority. A participant is removed from Reply list when their microphone is turned on.
Speak List Settings
To improve speaker management and clarity of the audio, there is a limit to the number of speakers at the same time. The number of active microphones is adjustable from 1 - 8. Once the limit is reached, a participant trying to turn on the microphone may be added to a request queue or denied access, depending on the microphone operating mode.
to define the following parameters:
Note: Interpreter consoles are not impacted by speak list settings.
Total: The maximum number of participants who can speak at the same time. This includes both delegate and chairman units. Limit: 8
Delegate: The maximum number of delegates allowed to speak at the same time. (Chairman units can always be switched On as long as the number set in ‘Max. speakers: Total’ is not exceeded.)
||Maximum number of speakers that can be placed in the Request list. Limit: 250
||Maximum number of speakers that can be placed in the Reply list. Limit: 250
Chairman (Moderator) Can Speak At Any Time Without Interrupting
Set the Max. speakers: Total limit one (1) higher than Max. speakers: Delegates.
Using FIFO Mode
First In, First Out (FIFO) mode automatically turns on microphones based on a chronological queue list. This mode works best if Max. speakers: Delegates is set to one (1), so that the delegate must wait to speak until the other is finished.
Adjust voice detection settings from
Voice Activation (VOX)
In VOX mode, the microphone activates automatically once a participant speaks. The mode is ideal for meetings that are more conversational, allowing back-and-forth communication that doesn't involve speak requests and button activation. The following settings allow VOX to be customized for the meeting:
|Voice Detection Threshold
||Determines the input level (dB) that activates the microphone. Lower settings activate the microphone with a quieter source, while higher settings require a louder source to activate the microphone.
||Determines how long a microphone remains active after a participant stops talking. The setting is selectable in 0.5 second increments.
||To ensure that only the speech from a participant activates the microphone, turn on the book drop feature. This quickly turns off a microphone that has been accidentally activated from a loud noise other than speech.
|Last Mic Stays Open
||This setting ensures that at least one microphone is always activated. This is useful for video or audio conferences with echo-canceling equipment.
Microphone Auto Off
This setting automatically turns off the microphone when the participant stops talking. This setting applies to systems in FIFO, Manual or Automatic modes. See
to adjust the release time for that mode.
|Automatic Off Time
||The time for a microphone to turn off after the participant stops speaking.
MXC components use a proprietary codec algorithm to prevent unauthorized devices from listening to the audio signal. To further protect the meeting, assign a password to the browser interface and enable security features on wireless routers.
Password Protect the Browser Interface
You can assign a password to restrict access to the browser interface. An independent password is assignable to each of the three interface addresses: administrator, chairman, and display.
- Sign into the browser interface as an administrator.
- Go to the Security page (
- Enter a password.
- Select Change Password to save the login information.
Note: passwords are cleared when the unit is factory reset from the CCU hardware.
Up to 31 channels are available for simultaneous interpretation of the meeting. The MXCIC interpretation unit connects to the DCS-LAN network from the CCU, transmitting audio to independent language channels. Participants listen to their language on headphones connected to their respective conference unit. See the MXCIC User Guide for more information.
Four languages are provided with the FL6000 mode license, and can be expanded to 8, 16, or 31 with an additional license.
Multi-language interpretation can be set up through the CCU web interface in standalone systems, or in SW6000. If more than 4 languages are needed, purchase and install an additional feature license before setting up interpretation.
Assign the number of interpretation channels needed (0 to 31) at
Note: When 0 is selected, only Floor audio (Channel 0) is available.
The Channel display setting determines whether the channel selectors on participant conference units display channel number or language abbreviation.
The Language setup list shows the channels defined in the Interpreter channels settings. Assign a language from the drop-down menu for each language.
Booth Channel Setup
To simplify managing multiple languages, interpreter consoles are grouped into Booths.
By default, Booth 1 is assigned to Channel 1, Booth 2 to Channel 2 etc., but languages can be manually assigned to booths at
. Multiple booths can be assigned to the same interpretation channel.
|Mic Interrupt Modes
setting applies when there are multiple interpreters on the same language. By default, interpreters alternate with each other and cannot override a unit already in use.|
Note: The primary (A) language corresponds to the booth language. Interpreters select their B and C languages from the MXCIC.
Interruption allowed: Interpreters can turn on their microphone at any time, taking over from the present interpreter. This applies to any interpreter with any setting
A Interrupt A: An interpreter turning on the A channel interrupts another interpreter's A channel.
A Interrupt B+C: An interpreter's A channel interrupts another interpreter's B or C channel, but not another interpreter's A channel.
A Interrupt A+B+C: An interpreter's A channel interrupts another interpreter, regardless of channel.
Interruption not allowed (default): When a channel is in use, another interpreter cannot turn on their microphone
||By default, interpretation channels with no active interpretation have the floor mix. To change the setting, go to
On: Language channels with no interpretation have the floor mix
Off: Language channels with no interpretation have no audio
||Choose the way the interpretation channel is displayed on the conference unit:
Number: Channel number
Abbreviation: First three letters of the language name in English
Wireless Language Distribution
Provide additional monitoring access by connecting a wireless language distribution system to the one of the CCU audio outputs. Use the browser interface to route the desired interpretation channels or a subset of microphones to that group output.
The DIR Digital Infrared Language System transmits this audio signal to a number of portable listening devices.
Wireless Language Distribution
Listening to Interpretation
Follow these steps to listen to one of the interpretation channels:
- Connect headphones to the headphone jack on the conference unit.
- Select a channel by pressing the selector buttons on the front of the unit.
Tip: When no channel is selected, the Auto Floor option in the Settings menu automatically switches to floor audio.
- Adjust the audio level of the headphones using the volume buttons.
The MXC Firmware Update Utility (FUU) is bundled with the firmware download on the Shure website. Use this program to keep your system updated to the latest firmware version, or to upload image files to compatible conference units. See the FUU help file for more.
- Make sure the system is on and operating properly.
- Download the latest firmware from the Shure website and extract the contents to your computer.
- Open the MXC Firmware Upgrade Utility folder and launch the application.
- Assign the connection method for the computer and equipment and select the OK button to exit the setup window:
Ethernet: Type the IP address of the CCU and use IP port 3142.
- Information about the CCU and all connected units display in the main window.
- Select the desired firmware release (typically the highest/latest) in the Selected Release Id drop-down list.
- Select the Upgrade System button to begin the firmware update process. A status window will appear and show the progress of the firmware upgrade.
Rackmounting the CCU
Install the central control unit in a standard 19” rack using the supplied 19” brackets. Remove the screws holding the top and bottom covers, then attach the brackets to the front of the unit using the same screws.
Important: Use the two 10 mm length self-threading screws closest to the front and the 8 mm length threaded screw furthest from the front.
The built-in fan draws air in on the left side and exhausts air on the right, and so does not require extra space above or below for cooling.
Installing the Conference Units
To accommodate numerous variables in each installation, the MXC series provides several models of conference unit in both tabletop and flush configurations.
Both models include the same features, but are useful for different environments and applications.
- No modification required to table surface
- Easily add or remove units
- Can be fixed to tabletop using size 4 screws
- Smaller footprint on table
- Clean, professional look
- No visible cables
Consider the following variables when making a decision on which type of MXC conference unit to purchase:
- Permanence: Is this a temporary or permanent installation?
- Cabling: Is your furniture historic or costly to modify?
Connecting DCS-LAN Equipment
Shure offers cables designed specifically for the MXC line of conferencing and discussion equipment. The Shure EC 6001 cables are high-quality Ethernet cables available in various lengths from 0.5 m to 100 m. Each cable has been tested to ensure reliable system performance. See the accessories section for ordering information on the EC 6001-xx.
Important: Shielded Cat5e (or higher) cables required for reliable system performance.
||Cat5e (or higher) twisted pair, F/UTP or U/FTP, minimum wire square: AWG 24
||Shielded RJ45, EIA 568-B wiring
- Max. 200 m from the CCU/EX/RP to the first MXC conference unit
- Max. 100 m between MXC units
- Max. 200 m between a CCU and a EX/RP and between EX/RP’s
- Max. 1000 m equivalent cable distance from the CCU to the last unit
- Each MXC unit represent an equivalent cable distance of 15 m
- Each EX/RP unit represent an equivalent cable distance of 100 m
- The longest feeding cable shall be used in the equivalent cable length calculation with redundant cabling
- No MXC units between cascaded EX/RP units, or between CCU and EX/RP units
- Max. 3 cascaded EX/RP units
Important: Cables and connectors must be shielded for stable system performance. If an installation does not use Shure EC 6001 cables, they must follow the Cat5e cable requirements.
Using Patch Panels
When designing a system with a patch panel, crimp the cable to the female shielded connector on the panel. Then simply use short jumper cables to connect to the conference units.
Continuity of Shielding
Shielding must be consistent through the DCS-LAN chain. Any cable or patch panel used for MXC components requires shielded RJ45 connectors. All MXC components feature shielded RJ45 female connectors.
Avoiding Accidental Grounding (Galvanic Isolation)
Avoid accidentally grounding the DCS-LAN signal by isolating front-plates, conference units and DCS-LAN connections in wall-panels from the building ground. The DCS-LAN uses the shield as a signal ground reference and cannot contact another ground anywhere in the connection.
Avoid Grounding in a Patch Panel
To avoid ground issues:
Plastic frames in patch panel: this ensures that the female RJ45 connectors do not ground to the chassis of the patch panel.
Blank space between connectors: leave a space between each female RJ45 connector in a patch panel.
Shielding continuity: each component in the chain must be shielded properly.
Note: The female connectors in all MXC components units feature an air gap that isolates the chassis of the connector and the chassis of the unit preventing any galvanic (physical and thus electrical) connection.
Properly Securing Cables
As with any cable carrying a signal, use care when installing the equipment.
Do not sharply bend the cable. Ethernet cables cannot bend more than four-times the diameter of the cable.
Do not over-fasten the cable. A pinched cable may not operate correctly.
Installing Large Systems
DCS-LAN Power Calculator
For many installations, the CCU supplies sufficient power for the conference units. The CCU can power multiple units at a time without additional equipment. The number of supported conference units depends on the size and layout of the installation.
To determine the specific requirements for your installation, use the DCS-LAN Power Calculator at https://dcslan.shure.com.
Power Depends on Installation Variables
To maximize the unit count without adding equipment:
- Use multiple chain outputs from the CCU. Units should be divided evenly across each chain
- Position the CCU so that the distance to the first microphone unit is as short as possible
- Keep the total cable length as short as possible
Power Supplies for Additional Components
To add additional components to the system, add an inline or rackmount power supply to the DCS-LAN chain. Multiple power supplies can be used to reach the maximum 3,800 supported units.
Note: To exceed 250 units, make sure the FL6000-3800 license has been purchased and installed in the CCU.
Inline Power Supply
Use the PI-6000 power inserter to add an inline power supply for additional conference units. The unit may be connected at any point in the chain to power the additional components.
Note: The PI-6000 cannot be used in systems with redundant cabling, and does not refresh the data signal.
Inline Power Supply (1x)
Rackmount Power Supply for 4 Additional Chains
Use the EX6010 rackmount extension unit to add additional components and configuration options. The unit expands the DCS chain into 4 separate outputs, each with a power supply equivalent of a CCU.
Note: Cable redundancy in can be achieved using the EX6010 by connecting the DCS-LAN OUT port of the last conference unit to an MXC Redundancy Interface Box (MXC-ACC-RIB), and looping back to a DCS-LAN port on the same EX6010.
Rackmount Power Supply (x4)
Attention: Always use shielded Cat 5e (or higher) network cables for reliable system operation. Ensure the right cables are used and installed correctly before referencing the troubleshooting table.

Microflex Complete System
The MXC system conforms to ISO 22259, the international standard for conference systems.
Audio performance specifications are measured from the audio input of a conference unit to the headphone output of a conference unit.
Connection to Main Power Supply
The CCU uses Cat5e, Cat6 or Cat7 F/UTP or U/FTP cables with shielded RJ45 connectors.
EIA 568-B wiring must be used.
Important: The names of Cat5/6/7 cable type have changed.
Important: Use only F/UTP or U/FTP (screened) cables and screened RJ45 connectors and not U/UTP cable, which is unscreened.
How to wire a Cat5e (EIA 568-B) cable to a RJ45 con.:
If other color codes are used then the four pairs are connected as follows:
Pair 2: Pin 1 & 2
Pair 3: Pin 3 & 6
Pair 1: Pin 4 & 5
Pair 4: Pin 7 & 8
The phase of the pairs must be correct and the wiring specification EIA 568-B (Cat5e).
Cat6 and Cat7 cables are normally only terminated in sockets (female) and not in cable plugs.
Cat6 and Cat7 can only be used for feeding cables terminating in wall outlets or patch panels.
