What is IntelliMix® Room?

IntelliMix Room is digital signal processing (DSP) software designed to optimize the performance of Shure networked microphones with videoconferencing software, resulting in better conference room audio all around. It's designed to run on the same computer as any videoconferencing software, which reduces the amount of equipment in the room.

What Do I Need to Use IntelliMix Room?

IntelliMix Room requires other software and hardware to work in your room. You'll need the following:

Software:

  • Shure Designer software installed on a computer connected to the same network as theIntelliMix Room.
    • Designer lets you control all installations of IntelliMix Room in one place.
    • It doesn't need to be on the same computer as IntelliMix Room.
  • Videoconferencing software (such as Zoom, Microsoft Teams, or BlueJeans) installed on the same computer/device as IntelliMix Room

Hardware:

  • Dante-enabled microphone, such as a Shure MXA910 or MXA310
  • PC or other physical device optimized for running IntelliMix Room (no virtual machines)
    • Windows 10 Pro, Enterprise, or IoT Enterprise (64 bit)
    • Processor: i5 quad core 1.9 GHz minimum
    • 8 GB RAM minimum
    • Solid state drive
    • Internet connection for licensing
  • Other room components, such as displays, cameras, loudspeakers, switches, Cat5e cables, and meeting control interfaces

Choosing a Channel Count

IntelliMix Room software is sold based on the number of IntelliMix DSP channels you need. For example, an 8-channel license has 8 channels with all of the IntelliMix DSP blocks (AEC, NR, and AGC).

The software always includes 8 auxiliary Dante input channels without IntelliMix processing. You shouldn't count these when deciding on your channel needs.

To choose a channel count:

  • Check your Dante-enabled microphone's channel count
    • Plan the microphone's coverage for the room, and see how many channels you will need. For example, if you use 2 MXA910s, a 16-channel license is the best option. For 2 MXA310s, an 8-channel license covers your needs.
    • For best results, each microphone channel should have an IntelliMix DSP input channel.
    • Larger rooms may require multiple microphones.
    • Don't count the microphone's automix out channel when calculating channel needs.
  • Plan for future device needs
    • If you plan to add more microphone channels with processing in future, include them in your channel count.
Room Size Small/Medium Large
Possible equipment combinations

Basics of Shure Designer Software

To use IntelliMix Room, you need Shure Designer software installed on a computer with a network connection to all IntelliMix Room installations.

Designer has some basic concepts that are important to understand as you start using IntelliMix Room:

Projects

  • Use to manage groups of locations.
  • Each project uses 1 license ID. All IntelliMix Room installations in a project use the same license ID.
    • If you're managing multiple customers with multiple license IDs, create separate projects to manage them.

Locations

  • Use to organize groups of devices installed in the same physical location, such as a room, an area, or a building floor.
  • If devices are in the same Designer location, you can route audio between them using the Signal flow tab.

Virtual Devices

  • Use to design coverage without being on the same network as the physical devices.
  • Push settings from virtual devices to physical devices once connected at the job site.

Online Devices

  • Shows every available device on your network.

Live Mode

  • Location-level setting that lets you control devices in real time.
  • Use to push settings to online devices or pull settings from online devices.

Synchronize

  • Use in Live mode to match the settings between virtual devices and online devices.
    • Push settings from virtual devices to online devices.
    • Pull settings from online devices to virtual devices.

Discovering IntelliMix Room in Designer

Each installation of IntelliMix Room appears as a separate device in Designer. Each installation's name matches the computer's network name.

To find any online installations:

  • Go to Online devices.
  • Use the checkboxes to select IntelliMix Room installations and add them to locations.

If you can't find some installations:

  1. Go to the computer that won't appear in Designer.
  2. Click the IntelliMix Room icon in the system tray.
  3. Make sure IntelliMix Room is using the same Shure control NIC (network interface card) as Designer.

Note: IntelliMix Room doesn't show up in Shure Update Utility or Shure Web Device Discovery.

Uninstalling IntelliMix Room

Before uninstalling, make sure you have admin rights and an internet connection for all devices.

  1. In Designer, find the devices that you plan to remove IntelliMix Room software from.
  2. Select the devices, and click Deactivate. After deactivation, the licenses are available to be used again. Devices with an internet connection release their licenses quickly. If the devices don't have an internet connection, it will take up to 7 days for the license to be available for reuse. To avoid this delay, connect devices to the internet before uninstalling.
  3. On each device, uninstall IntelliMix Room like any other software.

How IntelliMix Room Licenses Work

After installing IntelliMix Room on all devices, use Shure Designer software to activate your licenses. Designer is usually installed on a separate computer since it manages all installations of IntelliMix Room.

There are a couple terms to know as you manage licenses for IntelliMix Room:

  • Installation: A single instance of IntelliMix Room software installed on a device.
  • License: Each installation of IntelliMix Room needs one to run. Choose between an 8- or a 16-channel license.
  • Project: A grouping in Designer that has a collection of locations with devices. Each project uses 1 license ID. If you have multiple license IDs to manage, create separate projects for each one.
  • License ID: A 12-digit code used to activate all of your purchased installations in Designer. When you purchase a group of licenses from Shure, you'll receive this code in the purchase email (it's also available in your account at software.shure.com). Each customer has 1 license ID.

Illustration showing a Designer project with 8 IntelliMix Room installations.

Here's an example workflow for the whole process:

  1. Decide how many 8-channel and how many 16-channel licenses you need. Purchase them from Shure.
  2. Install IntelliMix Room on all devices.
  3. Install Designer on a computer connected to the same network and discover all of your installations.
  4. Create a project in Designer. Move all 8-channel installations into that project at the same time, and then repeat for 16-channel installations. You choose which type of license to use for the installations during this step.
  5. Click Activate and add your license ID. All installations with an internet connection should activate quickly.

Activating IntelliMix Room

To activate the software, you need:

  • A license for each installation
    • Licenses are based on the channel count (8 or 16 channels) for each installation of the software.
  • Your license ID
    • A license ID activates all licenses in your account.
    • Find in your purchase confirmation email, or in your account at software.shure.com.
  • Internet connection for all devices running IntelliMix Room

IntelliMix Room must be installed on a device before you can activate that license.

  1. In Designer, go to Online devices. Check that you can discover all installations.
    • Each installation appears as a separate device. The device name matches the PC's name.
    • If you don't see all installations, check the Shure control NIC settings on the computer running IntelliMix Room. Use the same network as Designer.
  2. Create a new project in Designer.
    • If you have many license IDs to manage, create a separate project for each license ID.
  3. Go to the project's Licenses page. From the list of available installations, select one to move into the project. Click Move into project.
    • If you add multiple installations to a project at the same time, choose installations that all use the same license type. For example, move all 8-channel licenses into the project first, and then repeat the process for your 16-channel licenses.

  4. Click Activate. Choose the license type for the installation and click Next.
  5. Add your license ID and click Activate. This license ID is used for all installations in the project. If the device running IntelliMix Room has an internet connection, the installation activates and is ready to use.

    Screenshot showing the license activation screen for IntelliMix Room in Designer software.

Next steps:

  • Create locations and add IntelliMix Room installations to them.
  • Route audio to IntelliMix Room to apply DSP.

Renewing a License

To renew your IntelliMix Room licenses, contact your Shure sales representative.

After you renew your licenses, your license ID stays the same. You won't need to make any changes to any existing room setups. All installations will continue running normally.

What Happens When My License Expires?

IntelliMix Room stops passing audio when your license expires.

You will receive email reminders to renew your license 90 days before it expires.

Deactivating Licenses

Deactivating the license for an IntelliMix Room installation causes that installation to stop passing audio.

After deactivation, the license is available to be used again on another installation of IntelliMix Room.

To deactivate licenses:

  1. In your project, go to Licenses. This page shows all IntelliMix Room installations in the project.
  2. Select the installations you want to deactivate.
  3. Click Deactivate. If the devices being deactivated have internet connections, you can reuse those licenses. If the devices being deactivated do not have internet connections, the licenses won't be available for reuse until they have an internet connection, or for up to 7 days.
  4. Deactivated licenses are now available to be assigned to other installations.

Moving or Reassigning Licenses

After purchasing, you might need to install IntelliMix Room on a different device than it was originally installed on.

To reassign a license to a new device:

  1. In your project, go to Licenses. This page shows all IntelliMix Room installations in the project.
  2. Select the license that you want to move to a different device.
  3. Click Deactivate. If the device running IntelliMix Room has an internet connection, it will deactivate quickly and you can reuse the license. If it does not have an internet connection, the license won't deactivate until the device is connected to the internet, or for up to 7 days.
  4. Install IntelliMix Room on the new device.
  5. In Designer, find the new installation of IntelliMix Room. Add it to the same project as the old installation.
  6. When prompted, choose the channel count that matches the old installation. Your license is now reassigned to the new device.

License Server Details

IntelliMix Room uses a cloud license server managed by Flexera. To see information about available licenses and your account, sign in at software.shure.com. Use the username and password you set up during purchase.

IntelliMix Room requires a continuous internet connection to verify each installation's license status. Every 12 hours, the installation checks in with the license server to validate its license. If a device running IntelliMix Room can't contact the cloud license server for 7 days, the installation becomes unlicensed and audio stops passing.

Using Videoconferencing Software with IntelliMix Room

To connect IntelliMix Room to videoconferencing software, select IntelliMix Room Echo Cancelling Speakerphone as the speaker and the microphone in your videoconferencing software. Do the same thing in the computer's sound settings.

Screenshot showing IntelliMix Room selected as the speaker and microphone in videoconferencing software.

The microphone setting sends signals to the videoconferencing software from any microphone connected to IntelliMix Room.

The speaker setting sends a far-end signal from the videoconferencing software to IntelliMix Room. This is how IntelliMix Room gets an AEC reference and a signal for local sound reinforcement.

If you choose a different source as the speaker, you won't be able to get far-end audio from the videoconferencing software into IntelliMix Room to use as an AEC reference.

Routing Microphone Signals to the DSP

To route your microphone's signal to IntelliMix Room for processing, use Designer.

This example reflects a small conference room with:

  1. MXA310 using 4 channels
  2. Computer with 8-channel IntelliMix Room and videoconferencing software installed
  3. Display and camera

To route signals to the DSP:

  1. Create a location in Designer. Add the MXA310 and IntelliMix Room installation to the location from the Online devices list.
    • Both devices must be in the same location to route audio between them.
  2. Open the location and go to Signal flow. This page creates Dante audio routes between Shure devices.
  3. Drag and drop from the MXA310's 4 outputs to any 4 inputs on IntelliMix Room. It's best to use the individual channel outputs from the microphone and not the automix output, because IntelliMix Room has its own automixer.

    Screenshot showing how to route audio from an MXA310 to IntelliMix Room using Shure Designer software.

  4. Click Optimize audio. This feature automatically changes microphone and DSP settings to work best for your connected devices. You can customize settings further, but optimize audio gives you a good starting point.
  5. Open IntelliMix Room's device configuration window. From here, you can adjust DSP settings and route the signal to other sources. Check that your mic inputs are using the AEC reference you want to use.
  6. To send your signal to other sources, go to Matrix mixer.
    • To send the automix signal to videoconferencing software, route to the virtual audio output.
    • To send the automix signal to other Dante sources, route to the appropriate Dante output. Use Dante Controller to route IntelliMix Room Dante outputs to non-Shure devices.

Note: If you're using a non-Shure Dante microphone, use Dante Controller to route the near-end signal to IntelliMix Room.

Routing Far-End Audio to IntelliMix Room

To use acoustic echo cancellation (AEC), you need to route a far-end signal to the software. The AEC uses that far-end signal as a reference and blocks it from being sent back to the far end as echo.

Each input channel can use a different AEC reference source. If all channels use the same source, select the AEC reference source on each input channel.

  1. In your conferencing software's settings, select IntelliMix Room Echo Cancelling Speakerphone as the playback device. This sends the far-end signal to IntelliMix Room's virtual audio input.

    Screenshot showing what source to select in videoconferencing software to get audio to IntelliMix Room.

  2. Open IntelliMix Room's configuration window in Designer.
  3. On each microphone input channel, select AEC. Choose the far-end reference source from the menu.
    • For best results, use the signal that feeds your local reinforcement system as the reference source.

    Screenshot showing how to select an AEC reference source in IntelliMix Room.

Sending Far-End Audio to Loudspeakers and Other Sources

  1. Go to Matrix mixer.
  2. Find the far-end signal, which comes to the software through the Virtual Audio Input.
  3. Check the box where the Virtual Audio Input and the destination intersect. You can also adjust crosspoint gain here. Common destinations include:
    • PC audio output (3.5 mm or HDMI connector): Go to Schematic view and click PC Output. Choose an output from the menu. Display speakers connected by HDMI cable or the 3.5 mm connector are common options.
    • Dante output destinations (loudspeakers or Shure ANI, for example)

  2. Increase the gain to between +10 and +15 dB, and then experiment with frequencies between 300 Hz and 900 Hz to pinpoint the resonant frequency
  3. Reduce the gain at the identified frequency (start between -3 and -6 dB) to minimize the unwanted room sound

EQ Contours for IntelliMix Room

Use the built-in equalizer contours to quickly apply EQ changes to any of the Dante input channels. Applying both EQ contours and other channel EQ filters has a cumulative effect, meaning that the EQ changes stack on top of each other.

Listen to and test your system as you make EQ changes.

Off: Turns off any active EQ contours

MXA910 High Pass: 300 Hz low-cut filter

MXA910 Low Shelf: 960 Hz, -10 dB low-shelf filter

MXA910 Multi-Band: 200 Hz low-cut filter, parametric 450 Hz, -10 dB, 2.87 Q, ½ octave parametric, 900 Hz, -10 dB, 2.87 Q, ½ octave parametric

MXA310 Low Cut: 180 Hz low-cut filter

Acoustic Echo Cancellation

In audio conferencing, a far-end talker may hear their voice echo as a result of a near-end microphone capturing audio from loudspeakers. Acoustic echo cancellation (AEC) is a DSP algorithm which identifies the far-end signal and stops it from being captured by the microphone to deliver clear, uninterrupted speech. During a conference call, the AEC works constantly to optimize processing as long as far-end audio is present.

When possible, optimize the acoustic environment using the following tips:

  • Reduce speaker volume
  • Position speakers farther from microphones
  • Avoid pointing speakers directly at microphone coverage areas

Selecting a Reference Signal for AEC

To apply AEC, provide a far end reference signal. For best results, use the signal that also feeds your local reinforcement system.

P300: Go to Schematic and click any AEC block. Choose the reference source, and the reference source changes for all AEC blocks.

MXA910: Route a far-end signal to the AEC Reference In channel.

IntelliMix Room: Go to Schematic and click an AEC block. Choose the reference source. Each block can use a different reference source, so set the reference for each AEC block.

AEC Settings

Reference Meter

Use the reference meter to visually verify the reference signal is present. The reference signal should not be clipping.

ERLE

Echo return loss enhancement (ERLE) displays the  dB level of signal reduction (the amount of echo being removed). If the reference source is connected properly, the ERLE meter activity generally corresponds to the reference meter.

Reference

Indicates which channel is serving as the far end reference signal.

Non-Linear Processing

The primary component of the acoustic echo canceller is an adaptive filter. Non-linear processing supplements the adaptive filter to remove any residual echo caused by acoustic irregularities or changes in the environment. Use the lowest possible setting that is effective in your room.

Low: Use in rooms with controlled acoustics and minimal echoes. This setting provides the most natural sound for full duplex.

Medium: Use in typical rooms as a starting point. If you hear echo artifacts, try using the high setting.

High: Use to provide the strongest echo reduction in rooms with bad acoustics, or in situations where the echo path frequently changes.

Noise Reduction

Noise reduction significantly reduces the amount of noise in the signal caused by projectors, HVAC systems, or other environmental noise. It is a dynamic processor, which calculates the noise floor in the room and removes noise throughout the entire spectrum with maximum transparency.

Settings

The noise reduction setting (low, medium, or high) represents the amount of reduction in  dB. Use the lowest possible setting that effectively lowers noise in the room.

Compressor

Use the compressor to control the dynamic range of the selected signal.

Threshold

When the audio signal exceeds the threshold value, the level is attenuated to prevent unwanted spikes in the output signal. The amount of attenuation is determined by the ratio value. Perform a soundcheck and set the threshold 3-6 dB above average talker levels, so the compressor only attenuates unexpected loud sounds.

Ratio

The ratio controls how much the signal is attenuated when it exceeds the threshold value. Higher ratios provide stronger attenuation. A lower ratio of 2:1 means that for every 2 dB the signal exceeds the threshold, the output signal will only exceed the threshold by 1 dB. A higher ratio of 10:1 means a loud sound that exceeds the threshold by 10 dB will only exceed the threshold by 1 dB, effectively reducing the signal by 9 dB.

Delay

Use delay to synchronize audio and video. When a video system introduces latency (where you hear someone speak, and their mouth moves later), add delay to align audio and video.

Delay is measured in milliseconds. If there is a significant difference between audio and video, start by using larger intervals of delay time (500-1000 ms). When the audio and video are slightly out of sync, use smaller intervals to fine-tune.

Automatic Gain Control (AGC)

Automatic gain control adjusts channel levels to ensure consistent volume for all talkers, in all scenarios. For quieter voices, it increases gain; for louder voices, it attenuates the signal.

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

Target Level (dBFS)

Represents the level that you want the gain to reach. This level is different from adjusting the input fader according to peak levels to avoid clipping. Suggested starting points:

  • P300: -32 dBFS
  • MXA910: -37 dBFS
  • IntelliMix Room: -32 dBFS

Maximum Boost ( dB)

Sets the maximum amount of gain that can be applied

Maximum Cut ( dB)

Sets the maximum attenuation that can be applied

Tip: Use the boost/cut meter to monitor the amount of gain added or subtracted from the signal. If this meter is always reaching the maximum boost or cut level, adjust the input fader so the signal is closer to the target level.

Mute and Fader Groups

You can link channels to each other to create groups for muting and fader controls. You link channels by clicking for the channels and the controls that you want linked. For example, if channels 1, 2, and 3 are linked for Mute, muting any of those individual channels mutes all of the linked channels.

Adjusting Input levels

The Inputs tab controls a channel's gain before it reaches the matrix mixer. However, you should also adjust the source's gain before it reaches IntelliMix Room.

To monitor a source's input level before IntelliMix Room processing: Set metering to Pre-gain in the Settings menu.

  1. Check the source level before it reaches IntelliMix Room. Verify that the networked microphones or other Dante sources are operating at nominal output levels.
  2. Adjust gain in the Inputs tab.
    • This gain stage adjusts the signal level before it reaches the matrix mixer.
    • Mix the levels as high as possible so that the loudest channel does not reach the peak level (0 dB) on the meter.

Pre- and Post-Gain Metering

The 2 metering modes allow you to monitor signal levels before and after the gain stages.

Input Metering

  • Pre-gain: Displays the pre-fader signal level. If signals are too low or clipping, adjust them at the source.
  • Post-gain: Displays the post-fader signal level, so the meters reflect gain adjustments on input faders. This meter does not include automatic gain control or any other processing.

Output Metering

  • Pre-gain: Displays signal levels after input gain has been applied, but before the output faders. This meter includes input faders, digital signal processing blocks, automixing, and crosspoint gain.
  • Post-gain: Displays the post-fader signal level sent to each output. This meter includes gain adjustments made on the output faders.

When to Use the Input and Automixer Gain Faders

There are 2 different gain faders that serve different purposes:

Input Gain (Pre-Gate)

To adjust, go to Inputs. These faders affect a channel's gain before it reaches the automixer and therefore affect the automixer's gating decision. Boosting the gain here will make the channel more sensitive to sound sources and more likely to gate on. Lowering gain here makes the channel less sensitive and less likely to gate on.

Automixer Gain (Post-Gate)

To adjust, go to Automixer. These faders adjust a channel's gain after automixer's gating decision. Adjusting the gain here will not affect the automixer's gating decision. Only use these faders to adjust the gain of a channel after you are satisfied with the automixer's gating behavior.

Matrix Mixer

The matrix mixer routes audio signals between inputs and outputs for simple and flexible routing:

  • Send a single input channel to multiple outputs
  • Send multiple input channels to a single output

Crosspoint Gain

Crosspoint gain adjusts the gain between a specific input and output, to create separate submixes without changing input or output fader settings. Select the dB value at any crosspoint to open the gain adjustment panel.

Gain staging: Input fader > crosspoint gain > output fader

Routing Channels

Connect inputs and outputs by selecting the box where they intersect.

Virtual Audio Input Dante Output 1
Automix Out Virtual Audio Output

Automix Modes

Gating

Gating mode delivers fast-acting, seamless channel gating and consistent perceived ambient sound levels. Off-attenuation in this mode is fixed at -20 dB per channel, regardless of the number of open channels.

Gain Sharing

Gain sharing mode dynamically balances system gain between open and closed channels. The system gain remains consistent by distributing gain across channels to equal one open channel. The scaled gain structure helps to reduce noise when there is a high channel count. When fewer channels are used, the lower off-attenuation provides transparent gating.

Manual

Manual mode sums all active tracks and sends the summed signal over a single Dante output. This provides the option to route an individual signal for reinforcement or recording, without enabling automixing. The settings from the faders in the standard monitoring view apply to the summed output.

Automix Settings

Note: Not all settings are available on all automixers.

Leave Last Mic On

Keeps the most recently used microphone channel active. The purpose of this feature is to keep natural room sound in the signal so that meeting participants on the far end know the audio signal has not been interrupted.

Gating Sensitivity

Changes the threshold of the level at which the gate is opened

Off Attenuation

Sets the level of signal reduction when a channel is not active

Hold Time

Sets the duration for which the channel remains open after the level drops below the gate threshold

Maximum Open Channels

Sets the maximum number of simultaneously active channels

Priority

When selected, this channel gate activates regardless of the number of maximum open channels.

Always On

When selected, this channel will always be active.

Send to Mix

When selected, sends the channel to the automix channel.

Solo

Mutes all of the other channels

Automix Gain Meter

When enabled, changes gain meters to display automix gating in real time. Channels that gate open will display more gain than channels that are closed (attenuated) in the mix.

Mic Optimization Mode (P300 only)

Select the microphone that is used with the automixer for best performance. For best results, route microphone channels to the processing device and click Auto configure (this automatically selects the correct mic optimization mode).

Use the Off setting when using a Shure Microflex® Wireless system, or traditional wired microphones.

Gate Inhibit (P300 only)

Enable gate inhibit to prevent far-end audio from gating on near-end microphone channels.

  1. Make sure all input gain levels are properly adjusted and all other automixer settings are configured.
  2. Disable Leave last mic on.
  3. Perform a test call with the far end to adjust the gate inhibit fader. Increase the fader level so that the far end indicator turns on, and far-end audio does not gate on the near-end automixer channels.
  4. Verify that near-end talkers still activate the automixer channels. If the channels do not turn on, lower the gate inhibit fader.
  5. Re-enable Leave last mic on if necessary.

Automixer Direct Out Tap Points

In the Automixer tab, use the menus below each channel to choose where the signal to the matrix mixer should come from.

All options include input channel gain, mute, solo, and PEQ.

Pre-Processing/Pre-Gate

Sends a signal without AEC, noise reduction, or AGC to the matrix mixer.

Post-Processing/Pre-Gate

Sends a signal with AEC and noise reduction but without automixer gating or AGC to the matrix mixer.

Post-Processing/Post-Gate

Sends a signal with automixer gating, AEC, and noise reduction but without AGC to the matrix mixer.

Pre-Processing/Post-Gate

Sends a signal with automixer gating but without AEC, noise reduction, or AGC to the matrix mixer.

Note: Direct out tap points are not available on all Shure automixers.

Network Setup Examples

IntelliMix Room works with many different types of networks. Here are some of the most common network setups:

  • Flat Network
    • All A/V and corporate devices are on the same network.
    • Use one network for Shure control and Dante audio data.

  • Corporate and AV Network
    • All A/V devices are on a separate network from the corporate network.
    • The computer running IntelliMix Room uses the A/V network for Dante audio and Shure control data.
    • The computer uses a wired connection to the corporate network for internet. USB 3.0 to gigabit Ethernet adapters are a common way to connect to 2 NICs.

  • Corporate and AV Network with Separate Internet Connections
    • IntelliMix Room and all other A/V devices are on a separate network that has its own internet connection, which is completely separate from the corporate network.
    • Use the A/V network for both Dante audio and Shure control data.

Choosing Networks for Shure Control and Dante Audio

This software sends 2 types of data over the network: Shure control data and Dante audio data. You can use the same NIC (network interface card) for both, or use 2 different NICs to separate the traffic.

During installation, you will be asked to choose a network for each one.

Shure control NIC:

  • Choose the network that Designer uses.
  • Used for device discovery and control

Dante audio NIC:

  • Choose the same network as other Dante devices to send audio between devices.
  • Cannot use Wi-Fi
  • Used to carry Dante digital audio

To change the NICs after installation, click the IntelliMix Room icon in the system tray of the computer running IntelliMix Room.

To change Designer's NIC, go to Settings.

Compatibility with Dante Domain Manager

This device is compatible with Dante Domain Manager software (DDM). DDM is network management software with user authentication, role-based security, and auditing features for Dante networks and Dante-enabled products.

Considerations for Shure devices controlled by DDM:

  • When you add Shure devices to a Dante domain, set the local controller access to Read Write. Otherwise, you won't be able to access to Dante settings, perform a factory reset, or update device firmware.
  • If the device and DDM can't communicate over the network for any reason, you won't be able to control Dante settings, perform a factory reset, or update device firmware. When the connection is reestablished, the device follows the policy set for it in the Dante domain.
  • If Dante device lock is on, DDM is offline, or the configuration of the device is set to Prevent, some device settings are disabled. These include: Dante encryption, MXW association, AD4 Dante browse and Dante cue, and SCM820 linking.

See Dante Domain Manager's documentation for more information.

Note: IntelliMix Room is not compatible with Dante's device lock feature.

Using Command Strings with IntelliMix Room

To control IntelliMix Room with third-party control systems, turn on command strings in Designer. You must choose an open port on the computer running IntelliMix Room to send and receive command strings.

Default port: 2202

Port range: 1025-65534

  1. In Designer, open the installation of IntelliMix Room you want to control and go to Settings > Command strings.
  2. Turn on command strings.
  3. Enter an available port to send and receive the command strings. Make sure that the port isn't being used by any other programs installed on the computer.

    To test if the port is available:

    • Send a <GET NA_DEVICE_NAME> command to IntelliMix Room. Make sure you are targeting IntelliMix Room's control IP address.
    • If you don't receive a response, the port is being used by another program.
    • Try a different port number and send the <GET NA_DEVICE_NAME> command until you receive a <REP NA_DEVICE_NAME {string}> response.
    • For best results, install all software on the computer before choosing a port for command strings. Adding new software after setting up command strings can change how the computer's ports are used, which can affect command strings.

A complete list of command strings is available at pubs.shure.com/command-strings/IntelliMixRoom.

Troubleshooting

Problem Solution
IntelliMix Room installations won't show up in Designer
  1. On the device running IntelliMix Room, click the system tray icon. Check that the installation is using the same Shure control network as Designer.
  2. Check if other Shure devices appear in Designer. If they do, open the Windows Task Manager and go to Services. Restart IntelliMix Room.
  3. Open Dante Controller. Check if the installation appears in Dante Controller.
  4. If the installation appears in Dante Controller, check firewall settings. Make sure it's not blocking any Shure traffic.
  5. Contact Shure support if it still doesn't appear in Designer.
Licenses won't activate in Designer
  1. Check that the device running IntelliMix Room has an internet connection. This is required for license activation.
  2. Go to your account at software.shure.com and check that you have enough licenses.
    • If you don't have enough licenses or need a different channel count, purchase more from your Shure sales representative.
  3. Contact Shure support.
Clicked IntelliMix Room icon in system tray, and the screen loads continuously This means IntelliMix Room isn't running properly. Try the following solutions:
  1. Open the Windows Task Manager and go to Services.
  2. Check if IntelliMix Room is running.
    • If it's stopped, right-click to start the service.
    • If it's running, right-click to stop the service and then restart it.
  3. Restart the computer and reopen from the system tray.
  4. Check if you can discover this IntelliMix Room installation in Designer or Dante Controller. If you can't discover the installation, uninstall it and then reinstall.
  5. Contact Shure support if it still doesn't run correctly.
IntelliMix Room won't pass audio
  1. Open the installation in Designer and check that it's unmuted.
  2. Check if the installation has a license that isn't expired. If it has a valid license, check the audio signal chain for inputs that are muted or routed incorrectly.
  3. If it doesn't have a license, find your license ID and add it to the project. Make sure the device with IntelliMix Room has a working internet connection.
    • Find the license ID in your purchase email or in your account at software.shure.com.
    • If you don't have enough licenses or need a different channel count, purchase more from your Shure sales representative.
  4. Check that the installation has the same channel count as what is available in your account for that license ID.
    • For example, if your installation has 8 channels, but your license ID only has one 16-channel license available, you need to purchase an 8-channel license.
  5. On the device running IntelliMix Room, try to access software.shure.com.
    • If you can't access it, try visiting another website. If you can, your firewall could be blocking traffic from the cloud license server. Adjust settings to allow traffic from Shure.
    • If you can access it, contact Shure support. The firewall is not interfering with the cloud license server.
Far end hears whispy echo sounds coming from room using IntelliMix Room

This is likely caused by latency introduced to the signal chain after the AEC reference signal. We have observed devices like soundbars or displays adding extra latency to the signal after it leaves IntelliMix Room. This difference between the AEC reference signal and what comes through the speakers causes problems for the echo canceler's training, and results in a whispy sound.

To fix this problem, delay your AEC reference signal so that it's closer to the signal coming out of the speakers.

  1. Using the matrix mixer, route the far-end signal (virtual audio input) to an unused Dante output.
  2. Set this Dante output as the AEC reference signal.
  3. Add delay to the Dante output. Start with 50-100 ms, and listen for echo artifacts on the far end. To provoke the artifacts, a single talker on the far end should make sibilant sounds (“Psst” or “Shhh”) and observe the echo coming back.
  4. Continue to increase or decrease the delay until the echo artifacts disappear from the perspective of the far-end participant.

Reset

Restore factory defaults: Resets all application and license settings to the factory defaults. Network settings remain the same.
