Connecting Conference Units and DCS-LAN Components
Conference units and DCS-LAN components are connected in sequence (daisy-chain) using the two RJ45 ports on each unit.
Connectors are not interchangeable: the previous unit must be connected to the IN port, and the following unit to the OUT port.
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.
1. Power off the CCU to protect the equipment during set up.
2. Connect a chain output on the CCU to the first conference unit with the shielded Cat5e cable.

Participants can cast or change votes for the duration of the voting session.
Note: In ‘Secret’ voting sessions, LEDs stop flashing after the vote is cast; however, votes can still be changed for the duration of the voting session.
Audio Settings
Microphone Functionality
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.
Shure Incorporated
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
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 (Audio > Group Setup) 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:
1. Route microphones to Group A to add them to the floor mix (selected by default): Audio > Group Setup
2. Select the audio sources for the loudspeaker and Channel 0 (headphone): Audio > Input Control:
◦ Floor (default)
◦ Audio In 1
◦ Audio In 2
Shure Incorporated
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 Adjustment
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:
From the Browser Interface
Go to the Loudspeaker Control page (Audio > Loudspeaker Control) or the Microphone
From the CCU
Scroll to the Loudspeaker Menu (loudspk. control > loudspk. volume > db)
control screen
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 channel selectors.
Channels 1 - 31 are dedicated for language interpretation. Participants select one of the channels to listen to their language
during a multilingual event. The audio source comes from interpreter stations transmitting onto their selected channel. See the
Interpretation section of this guide for more details.
Channel 0 (the floor channel) is typically selected by interpreters to provide simultaneous interpretation of those addressing the
floor, or by participants to listen to the floor channel on headphones.
1. Connect headphones to the headphone jack on the side of the conference unit.
2. Select a channel by pressing the channel selector button(s).
3. Adjust the volume of the headphones using the unit's volume controls.
Shure Incorporated
Analog Audio Outputs
Eight analog outputs are available for recording, language distribution system, teleconferencing unit, or an external PA system.
Eight Analog Outputs
Select the audio source for each analog output
Go to Audio > Output Control and choose from the following options:
• Group: Eight separate groups for isolating specific microphones. This selection corresponds to the groups configured
from the Group Setup page.
• Ch. 1 -31: Interpretation channels
• Floor: The audio from all open microphones that are routed to Group A (floor mix). There are three variations on this mix
to choose from:
◦ Ch. 0: Headphone mix with AGC, useful for sending to an IR language distribution system.
◦ Floor 1: Loudspeaker mix, useful for sending to a PA or broadcast equipment.
◦ Floor 2: Loudspeaker mix with volume attenuation (Audio > Loudspeaker Control)
Adding an External Audio Source
Two inputs are available on the CCU for adding an external audio source to the system, often useful for teleconferencing or internet calling.
1. Connect a line-level audio source, such as the audio output of a computer, teleconferencing unit, or wireless microphone system to the audio input on the CCU back panel.
2. Open the web interface to Audio > Input Control.
3. Select the input gain according to the output of the external device. If necessary, select 10 dB for a slight gain boost.
4. Select the routing for the audio channel:
◦ Loudspeaker: to all microphone unit loudspeakers
◦ Ch. 0: to the headphone output on the microphone unit
5. If desired, route the channel to Output A (Group) to output a blend of the external source with the floor mix from the
conference units:
◦ Deselect for teleconferencing or signal processing to avoid a feedback loop
◦ Select for a wireless microphone to be blended with other microphone unit audio
6. Adjust the volume at the audio source to mix naturally with speech levels of the conference units.

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.
1. Connect the EEM signal to Input 2.
2. Connect a switch to the block connector.
3. Close the switch and test the audio signal. Adjust the volume at the audio source to the desired level.

Meeting Configuration
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:
1. Go to Devices > Device setup.
2. 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.
3. Reassign seat numbers to match the actual seat numbers in the room or on your seating chart.
4. 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.
5. 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 De­
vices > Participant setup menu:
Shure Incorporated
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.
Meeting Controls
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
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
Shure Incorporated
Microphone Settings
Speak Mode
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.
Shure Incorporated
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.
• Not allowed: When the number of open delegate microphones reaches the Max. speakers: Delegates limit, or the number
of open chairman microphones reaches the Max. speakers: Total limit, no more delegate/chairman microphones can be
opened and the green LED will flash 3 times.
Note: When the Max. speakers: Delegates limit is met but the Max. speakers: Totallimit is not, a chairman can interrupt the first delegate added to the
Speak list.
• Lower: When the Max. speakers: Delegates limit is reached, a speaker interrupts the first delegate added to the speak list
with lower priority.
• Same or lower: Any participant can interrupt the first delegate added to the Speak list with the same or lower priority
when the Max. speakers limit is reached. If only chairman microphones are active, a chairman can interrupt the first chairman added to the Speak list.
Individual priority settings can be manually determined in the Speak priority column under Devices > Participant setup.
Speak Button Lock
When controlling microphones remotely, the Speak button can be temporarily disabled to avoid unintentional activation by the
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.
Shure Incorporated
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.
Reply Functionality
The reply mode enables participants to briefly comment or ask a question to the present speaker. This allows a concise followup 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.
Go to Meeting controls > Speak list settings to define the following parameters:
Note: Interpreter consoles are not impacted by speak list settings.
Max speakers
• 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.)
Max Requests
Maximum number of speakers that can be placed in the Request list. Limit: 250
Max Replies
Maximum number of speakers that can be placed in the Reply list. Limit: 250
Shure Incorporated
Example Settings
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.
Voice Detection
Adjust voice detection settings from Meeting controls > Voice detection.
Shure Incorporated
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:
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.
Voice Detection Threshold
0 dB
-12 dB
8 dB
Determines how long a microphone remains active after a participant stops talking. The setting is selectable in 0.5 second increments.
4 seconds
1 seconds
10 seconds
Release Time
Book Drop
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 Meeting controls > Voice detection to adjust the release time for that mode.

3. Enter a password.
4. Select Change Password to save the login information.
Note: passwords are cleared when the unit is factory reset from the CCU hardware.
Language Interpretation
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.
Shure Incorporated
Four languages are provided with the FL6000 mode license, and can be expanded to 8, 16, or 31 with an additional license.
Interpretation Setup
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.
Interpretation Channels
Assign the number of interpretation channels needed (0 to 31) at Interpretation > Interpretation channels.
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.
Language Setup
The Language setup list shows the channels defined in the Interpreter channels settings. Assign a language from the dropdown 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
Interpretation > Booth channel setup. Multiple booths can be assigned to the same interpretation channel.
Interpretation Settings
The Interpretation > Mic interrupt modes setting applies when there are multiple inMic Interrupt Modes
terpreters on the same language. By default, interpreters alternate with each other and cannot override a unit already in use.
Shure Incorporated
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
• 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 Interpretation > Auto floor.

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.
Installation options
Both models include the same features, but are useful for different environments and applications.
Tabletop (Portable)
• No modification required to table surface
• Easily add or remove units
• Can be fixed to tabletop using size 4 screws
Shure Incorporated
• Smaller footprint on table
• Clean, professional look
• No visible cables
Flush-Mount (Installed)
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.
Cable Requirements
Cat5e (or higher) twisted pair, F/UTP or U/FTP, minimum wire square: AWG 24
Shielded RJ45, EIA 568-B wiring
Cable length
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
1. Each MXC unit represent an equivalent cable distance of 15 m
2. Each EX/RP unit represent an equivalent cable distance of 100 m
3. The longest feeding cable shall be used in the equivalent cable length calculation
with redundant cabling
5. No MXC units between cascaded EX/RP units, or between CCU and EX/RP units
6. 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.
Shure Incorporated
Avoiding Accidental Grounding (Galvanic Isolation)
Avoid accidentally grounding the DCS-LAN signal by isolating front-plates, conference units and DCS-LAN connections in wallpanels 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
• 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.
Shure Incorporated
Bending Rule
Do not sharply bend the cable. Ethernet cables cannot bend more than four-times the diameter of the cable.
Shure Incorporated
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
Power Depends on Installation Variables
To maximize the unit count without adding equipment:
1. Use multiple chain outputs from the CCU. Units should be divided evenly across each chain
2. Position the CCU so that the distance to the first microphone unit is as short as possible
3. 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.
Shure Incorporated
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.
The light rings on the microphone are
constantly flashing after the system is
powered on.
Check that cables are shielded Cat 5e (or higher)
