    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.
    3. Connect the rest of the conference units in sequence, using the RJ45 jacks on the bottom of each unit.
    4. Use the included cable clamp to secure the cables in place.
    5. 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

    Exclusive Mutes all delegate microphones and activates the chairman microphone while the button is active

    Agenda

    If SW6000 is in use, the Agenda screen displays the agenda for an active meeting. Selecting an item displays full details. The agenda is created in SW6000.

    The Chairman can set an agenda subject active by selecting a subject, where a popup will appear showing the subject details. The popup will have the ‘Set active’ and Close’ option.

    If there is no active meeting, the Agenda screen allows the Chairman to select and start/stop an upcoming meeting.

    Voting/Result Menu

    The Voting/result menu is always available for the Chairman, and displays the available voting options. In standalone mode, four options are available, while SW6000 enables all options (voting configurations) defined in SW6000.

    The Voting/result menu is only available for delegates when a voting result is available.

    The screen for casting vote is automatically displayed on all conference units when a voting session or attendance check is started.

    Results

    The Results pop-up is only shown when a vote or attendance check is completed. This is only shown after a vote is finished. Click OK to dismiss the

    Note: Results are not available or displayed for cancelled voting sessions.

    Channel Selectors and Volume Control

    The channel selectors and volume control allow two users to select an available interpretation audio channel and set the headphone volume. The respective controls are available when a headphone is plugged into the corresponding input.

    Voting Functionality

    Voting functionality can be controlled using an MXC640 conference unit in chairman mode, or through the SW6000 Parliamentary Voting software module.

    In standalone mode, the CCU supports 2-, 3-, and 5-button voting configurations. Live results are available during voting sessions, unless the chairman has defined the session as 'Secret.' The CCU delivers final results at the end of voting sessions and attendance checks.

    User Controls & Indications

    The units featuring voting functionality will include the following controls and interfaces.

    + Casts a 'Yes' vote, or declares the user as 'Present'
    0 Records an 'Abstain' response
    - Casts a 'No' vote
    + + Casts a '+ +' vote
    - - Casts a '- -' vote

    The voting button LEDs indicate to participants which options are available. Attendance checks are indicated by the + LED.

    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.

    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 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

    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.

      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.

    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.

    Delegate 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 Delegates to Turn Off Their Microphones

    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.

    Speak Button Behavior

    • Toggle: Pushing the Speak button on a conference unit toggles the Speak state on or off.
    • Press and hold: Pushing the Speak button enables the Speak function. Releasing the button disables the Speak function.

      Note: In Manual and FIFO, this option only applies to Chairman units. Pushing the Speak button on a delegate unit adds the participant to the Speak list.

    Mute Button Behavior (MXC Only)

    • 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 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.

    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
    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 Activation

    In Voice Activation (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 (under Meeting controls > Voice detection) allow VOX to be customized for the meeting, depending on your system.

    MXC Mode

    Voice activation mode is automatically detected. In systems consisting of only MXC conference units, the VOX mode will be MXC.

    When voice activation is active, MXC conference configured as single units work in MXC VOX mode. Dual MXC units work in automatic mode.

    Voice Detection Threshold Offset Determines the microphone sensitivity. Lower settings activate the microphone with a quieter source, while higher settings require a louder source to activate the microphone.
    Default 0 dB
    Minimum -12 dB
    Maximum 12 dB
    Release Time Determines how long a microphone remains active after a participant stops talking. The setting is selectable in 0.5 second increments.
    Default 4 seconds
    Minimum 1 seconds
    Maximum 10 seconds
    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.

    Advanced Settings

    Room Reverberation Time Adjusts the microphone activation threshold to account for room acoustics. Lower reverberation time makes microphones easier to activate, higher reverberation time increases the activation threshold.
    Threshold for Additional Mic Activation The amount of input needed to activate an additional microphone while an active speaker is speaking.

    6000 Mode

    In systems where legacy 5900 or 6000 conference units are connected, the VOX mode will be 6000.

    When voice activation is active, legacy conference units work in 6000 VOX mode, with any MXC units in the system working in automatic mode.

    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.
    Default 0 dB
    Minimum -12 dB
    Maximum 8 dB
    Release Time Determines how long a microphone remains active after a participant stops talking. The setting is selectable in 0.5 second increments.
    Default 4 seconds
    Minimum 1 seconds
    Maximum 10 seconds
    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.

    • Off (default)
    • On
    Automatic Off Time The time for a microphone to turn off after the participant stops speaking.
    Default 20 seconds
    Minimum 5 seconds
    Maximum 60 seconds

    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.

    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 (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.

    Loudspeaker Volume

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

    Mix-Minus In Loudspeaker

    By default, activating a conference unit's microphone mutes that unit's loudspeaker. When mix-minus is enabled, activating the microphone reduces the loudspeaker volume by 6 dB, and audio from the unit's own microphone is not heard in that unit's loudspeaker. (If mix-minus is enabled but cannot be applied, the unit's loudspeaker will be muted when the microphone is active.)

    Note: To avoid feedback, limit the maximum number of open microphones to 4 in systems with mix-minus enabled.

    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 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.

    Input Control Page

    Audio > Input Control

    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.

    Connecting External Audio Sources to MXCMIU

    An MXCMIU configured as a single unit allows audio input switching between Port A, XLR Line and XLR Mic through the Device setup screen:

    When XLR Line or XLR Mic are selected, microphones on connected faceplates are disabled, but controls and loudspeaker are active.

    Current audio settings (0 to -6 dB) are maintained for Port A and Port B audio inputs. The default XLR input is 0 dB, with an adjustable range of +10 dB to -20 dB.

    The XLR port is disabled when the MXCMIU is configured as a dual unit.

    When the MXCMIU is configured as an interpreter source, XLR mic and XLR line inputs can route audio to an interpreter channel. Detailed settings are configured at Interpretation > MIU Setup.

    Ambient Audio

    The ambient room sound informs participants that these pauses in speech are not a connection or audio issue, which is especially helpful for interpreters or other participants that are not in the same room as the conference.

    An MXCMIU configured as an ambient unit allows audio input switching between Port A, XLR Line and XLR Mic through the Device setup screen. Controls and loudspeaker on connected faceplates are deactivated.

    Individual audio settings are disabled for ambient units. Activate and adjust the global ambient microphone level at Audio > Ambient Microphone. Up to 5 units can be configured to provide ambient audio.

    Note: The ambient microphones switch off automatically when another microphone is switched on, or the sound source is an external system, such as a laptop or videoconference system.

    Audio Output Unit

    The AO 6004 audio output unit outputs 4 floor or language channels to IR language distribution systems, streaming, or recording devices. Use the Description field to describe the function of the AO 6004, and set the channel and volume for each output using the dropdown menus.

    Note: The AO 6008 audio output unit is not supported by the CCU control software at this time.

    Devices

    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 unit type. If the unit type can be changed, a dropdown list is available to make the selection. Possible selections include Single unit, Dual unit, Ambient and Interpreter

    Changing the unit type restarts the unit. If the type is changed to Dual unit, the original entry is removed and two new entries with new seat numbers are created when the page information refreshes.

    Note: An MXCMIU can be configured as a single or dual unit, or as an ambient microphone. For more information, see Connecting External Audio Sources to MXCMIU.

    Assigning Names and Roles

    MXC conference units can support Chairman or Delegate roles for meeting participants. Roles are set manually in the Devices > Participant setup menu:

    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.

    Name Sign Setup (CCU Integration)

    The CCU can write to any MXCSIGN units connected to the same wired network. From the CCU web interface, go to Devices > Name sign setup.

    • The Content selection options determine what information is shown on the MXCSIGN:
      Participant names The MXCSIGN displays the content for the associated seat number configured in the Participant setup screen. Consequently, when NFC cards are in use, the participant information from the card is used.
      Text lines Content is pulled from the Text, first line and Text, second line fields.

      Note: When a number is assigned under Seat #: Dual B, the first line of text corresponds to the participant in Seat A, the second line corresponds to the participant in Seat B.
      Identify The serial number and assigned seat number (if any) is displayed.
      Blank All information is removed from the MXCSIGN.
    • Font size change defaults to 0, which represents the default font size for the assigned template. Fonts can be increased or decreased, with values ranging from 190 to -70.
    • Apply content pushes the selected information to the connected MXCSIGN units
    • Delete all text lines clears the values in the text line fields

    Display Templates

    Information sent to the MXCSIGN from the CCU uses predefined templates depending on what fields are populated:

    Active Content Seat #: Single / Dual A Seat #: Dual B Text, first line Text, second line Template
    Participant names X
    X X
    Text lines X X
    X X X
    X X X X

    Security

    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.

    1. Sign into the browser interface as an administrator.
    2. Go to the Security page (System > Security)
    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 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, and support for 8, 16, or 31 are available with additional licenses.

    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 how channel selectors on participant conference units display the interpretation channel:

    • Number: Channel number
    • Abbreviation: First three letters of the language name in English

    Language Setup

    The Language setup list shows the channels defined in the Interpreter channels settings. Assign a language from the drop-down menu for each language.

    MIU Setup

    MXCMIU units configured as Interpreter source (under Devices > Device setup are listed with the following setup options:

    • MIU Interpreter Devices: Enable or disable all units. When Enable all is selected, the state for all units is Off. Units are disabled by default.
    • Audio level: Use the dropdown list to set the audio input level (10dB to -20 dB).
    • Channel #: Select the interpretation audio channel.
    • State: MXCMIU units configured as interpreter source are Off by default.

    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.

    Auto Floor

    By default, interpretation channels with no active interpretation have the floor mix. To change the setting, go to Interpretation > Auto floor.

    • On: Language channels with no interpretation have the floor mix
    • Off: Language channels with no interpretation have no audio

    Mic Button Setup

    The Interpretation > Mic button setup 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

    Green Indication In Mic Button

    Allows green indication in the microphone button to indicate to the interpreter in the microphone button, if he might interrupt another interpreter or not, if he start to interpret.

    • Disabled: White LED indicates the microphone is not in use; red LED indicates the microphone is in use
    • When interpreter booth is not active: Green LED indicates no interpretation is taking place in the booth
    • When interpreter booth or selected channel is not active: Green LED indicates no interpretation is taking place on the selected channel (the channel is not occupied) and interpretation is not taking place in the booth

    Listening to Interpretation

    Follow these steps to listen to one of the interpretation channels:

    1. Connect headphones to the headphone jack on the conference unit.
    2. 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.

    3. Adjust the audio level of the headphones using the volume buttons.

    Interpretation Using MXC605

    MXC605 portable units can be configured as simple Interpreter units, with limited functionality. Interpreters can access the first 4 interpretation channels configured in the system, and can listen to the floor audio over headphones.

    To change the interpretation channel, turn off the microphone and press the channel select button.

    To temporarily mute the outgoing audio, press and hold the function button.

    MXC605 Interpreter units can be assigned to booths in SW6000. If the booth's A-language matches the channel assigned, the unit will provide A-language interpretation for that booth; otherwise, the unit will provide B-language interpretation.

    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

    Firmware Update

    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 guide for more information.)

    1. Make sure the system is on and operating properly.
    2. Download the latest firmware from the Shure website and extract the contents to your computer.
    3. Open the MXC Firmware Upgrade Utility folder and launch the application.
    4. 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.
    5. Information about the CCU and all connected units display in the main window.
    6. Select the desired firmware release (typically the highest/latest) in the Selected Release Id drop-down list.
    7. 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.

    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
    Flush-Mount (Installed)
    • 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.

    DCS-LAN Tool

    The Shure DCS-LAN Tool is a desktop application for planning and managing conference and discussion systems. The software calculates the power consumption of connected MXC or legacy DIS components, identifying the need for additional components, such as power inserters or expansion units. The application is available on shure.com.

    Cable Requirements

    Type Cat5e (or higher) twisted pair, F/UTP or U/FTP, minimum wire square: AWG 24
    Connector Shielded RJ45, EIA 568-B wiring
    Cable length
    1. Max. 200 m from the CCU/EX/RP to the first MXC conference unit
    2. Max. 100 m between MXC units
    3. Max. 200 m between a CCU and a EX/RP and between EX/RP’s
    4. 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.

    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.

    Bending Rule

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

    Pinching

    Do not over-fasten the cable. A pinched cable may not operate correctly.

    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.

    The light rings on the microphone are constantly flashing after the system is powered on.
    • Check that cables are shielded Cat 5e (or higher)
    • Ensure that all the connectors on all the cables are firmly inserted in the sockets on the units
    • Check that the feeding cables from the conference units are properly inserted into the 'DCS-LAN' socket on the DIS-CCU.
    The Function button on the Chairman Unit does not switch off the Delegate Units
    • Check to make sure the unit is configured as Chairman and that the function button is configured as All del off
    The audio from an Interpreter Unit cannot be heard in the headphone of Delegate or Chairman Units
    • Check the headphone volume control on the units
    • Check the channel selection on the conference units
    • Check that the headphone plug is firmly inserted in the headphone jack
    • Check that the light ring on the microphone on the interpreter console is illuminated and that the gooseneck microphone is firmly inserted in the socket
    There is no audio coming from the built-in loudspeakers
    • Check the 'Loudspeaker Volume' setting using either the interactive menu on the CCU or using the browser control.
    • Check that the loudspeaker is set to sufficient volume. (DIS-CCU browser  > Audio > Loudspeaker Control.)
    • Check that the floor mix is assigned to loudspeaker (DIS-CCU browser  > Audio > Input Control > Loudspeaker
    • Check that the seats are selected in 'Group A' (DIS-CCU browser  > Audio > Group Setup). 'Group A' is always used as the source for the floor mix. If a unit is not selected in 'Group A', the audio from the unit will not be heard in the built-in loudspeakers.
    A microphone cannot be turned 'On'
    • Check the cables. All cabling must be Cat 5e or higher with shielded RJ45 cables.
    • Check the settings Max. Delegate Speaker and Max. Total Speakers to make sure there is room for another microphone to turn on.
    • Check the Speak Mode to make sure the mode allows participants to turn on their own microphones.
    The CCU browser application will not open on a PC
    • Using the interactive menu on the CCU, check the IP address: LAN setup  > Acquire IP address. Use this IP address using the browser
    • Verify that the CCU and the PC are connected to the same network
    • Check the LAN cable connections
    • Verify that the tablet or laptop is connected to a proper wireless access point

    • Check that the CCU is connected to the same subnet as the wireless access point
