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 con-
ference 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.

3.

Connect the rest of the conference units in sequence, using the RJ45 jacks on the bottom of each unit.

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.

37/75

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
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 (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

•

None

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 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 Inter-

face

From the CCU

Go to the Loudspeaker Control page (Audio > Loudspeaker Control) or the Microphone 
control screen

Scroll to the Loudspeaker Menu (loudspk. control > loudspk. volume > db)

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.

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 in-

ternet calling.

1.

Connect a line-level audio source, such as the audio output of a computer, teleconferencing unit, or wireless micro-

phone 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.

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 out-

put 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:

42/75

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 micro-

phone 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 partici-

pants, 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

43/75

Microphone Settings

Shure Incorporated

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 sec-
ond 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 con-

trol 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 adminis-

trator 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 re-

quest queue until the maximum requests is reached.

44/75

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 sec-
onds.

Dual units do not support VOX. If VOX is selected, a dual unit will operate in Auto mode. Chairman units are always in Au-

to 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 chair-
man 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
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.

45/75

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 mi-
crophone.

•

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 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 con-

ference 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. Partici-

pants 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 re-

quest 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.

•

Total: The maximum number of participants who can speak at the same time. This in-

cludes both delegate and chairman units. Limit: 8

Max speakers

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

•

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. speak-
ers: Total’ is not exceeded.)

46/75

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.

47/75

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.

Determines how long a microphone remains active after a participant stops talking. The set-

ting is selectable in 0.5 second increments.

Default 4 seconds

Minimum 1 seconds

Maximum 10 seconds

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.

This setting ensures that at least one microphone is always activated. This is useful for video
or audio conferences with echo-canceling equipment.

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 shield-

ed 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 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.

55/75

Shure Incorporated

Bending Rule

Do not sharply bend the cable. Ethernet cables cannot bend more than four-times the diameter of the cable.

Pinching

56/75

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 https://dcslan.shure.com.

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.

57/75

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 Inter-

face Box (MXC-ACC-RIB), and looping back to a DCS-LAN port on the same EX6010.

Rackmount Power Supply (x4)

Troubleshooting

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.

Check that cables are shielded Cat 5e (or higher)

The light rings on the microphone are

constantly flashing after the system is

powered on.

Ensure that all the connectors on all the cables are firmly inserted in the sock-

ets on the units
Check that the feeding cables from the conference units are properly inserted
into the 'DCS-LAN' socket on the DIS-CCU.

unit is not selected in 'Group A', the audio from the unit will not be heard in the
built-in loudspeakers.

Check the cables. All cabling must be Cat 5e or higher with shielded RJ45 ca-

bles.
