The Dante Controller is a free software program created by Audinate™ to configure and manage networks of Dante-enabled devices. Use the Controller to create audio routes between networked components and to monitor the status of online devices.

Dante Controller and Lock Settings

Version 1.2.X introduces support for Dante Device Lock for AD4D and AD4Q. Dante Device Lock is a feature of Dante Controller that allows you to lock and unlock supported Dante devices using a 4-digit PIN (Personal Identification Number). When a device has a Dante lock turned on, Dante audio will continue to flow according to existing subscriptions, but its subscriptions and settings can't be controlled or configured.

If you forget your Dante Device Lock PIN, see the Device Lock section of the Dante Controller User Guide for instructions on how to proceed.

Dante Domain Manager

Version 1.2.X introduces support for Dante Domain Manager (DDM) for AD4D and AD4Q. DDM is network management software that enables user authentication, role based security, and audit capabilities for Dante networks and Dante-enabled products.

Considerations for Shure devices controlled by DDM:

  • When you add Shure devices to a Dante domain, leave the local controller access setting in Read Write. Otherwise, access to Dante settings, device factory reset, and device firmware updates will be disabled.
  • When a device is managed by a Dante Domain and the Dante Domain is disconnected, access to Dante settings, device factory reset and device firmware updates will be disabled. When a device reconnects to the Dante Domain, it follows the policy set for it in the Dante Domain.

See the Dante Domain Manager User Guide for more information.

Networking Modes and Switch Configuration

The receiver offers two selectable networking modes:

  • Split/Redundant: This mode places Dante audio and Shure control on separate networks, while allowing you to take advantage of Dante redundancy.
  • Switched: In Switched mode, the receiver acts as a 4-port network switch. Shure control and Dante audio are present on all network ports.

IP Address Configuration

An IP address must be assigned to each device in the network to ensure communication and control between components. Valid IP addresses can be assigned automatically using a DHCP server or manually from a list of valid IP addresses. If using Dante audio, a separate Dante IP address must also be assigned to the receiver.

Automatic IP Addressing Mode

  1. If using a DHCP capable Ethernet switch, set the DHCP switch to ON.
  2. From the Device Configuration menu: Network Configuration > Next
  3. Press the control wheel to enable editing of the Mode, and then set the mode to Automatic.

Manual IP addressing Mode

  1. From the Device Configuration menu: Network Configuration > Next
  2. Press the control wheel to enable editing of the Mode, and then set the mode to Manual
  3. Set valid IP addresses and subnet values, and then press ENTER to save.

Network Browser

The network browser allows you to discover other devices connected to your network. You can view information about the discovered devices, including Device ID, IP address, firmware version, and model name.

  1. From the Device Configuration menu: Network Browser
  2. When selected, the Network Browser will discover and list devices on the network.
  3. Use the control wheel to scroll through and select devices.

The following information and actions are available from the Network Browser:

  • Show: Selects the device from the list
  • Flash: Flashes front panel LEDs
  • Info: Displays the device ID, model, IP address, and firmware version
  • Flash All: Flashes the front panel of all devices

Network Troubleshooting

  • Use only one DHCP server per network
  • All devices must share the same subnet mask
  • All receivers must have the same level of firmware revision installed
  • Look for the illuminated network icon on the front panel or display of each device:

    If the icon is not illuminated, check the cable connection and the LEDs on the network jack.

    If the LEDs are not on and the cable is plugged in, replace the cable and recheck the LEDs and network icon.

To check connectivity of WWB6 to the network:

  1. Start Wireless Workbench software and use Inventory view to see devices connected to the network.
  2. Find the IP address from one of the devices on the network and see if you can ping it from the computer running Wireless Workbench.
  3. From a WINDOWS/MAC command prompt, type ‘ping IPADDRESS’ of the device (e.g. "ping").
  4. If the ping returns success (no packet loss), then the computer can see the device on the network. If the ping returns failure (100% packet loss), then check the IP address of the computer to ensure it’s on the same subnet.
  5. If the pings are successful and the devices still do not show up in the WWB6 inventory, check to ensure all firewalls are either disabled or allow the WWB network traffic to pass to the application. Check that firewall settings are not blocking network access.


Assigning a Device ID

Assigning custom names or IDs helps with monitoring and organizing when the receiver is part of a large system.

  1. From the Device Configuration menu: Device ID

Make sure that the receiver and transmitter are receiving sufficient voltage. Check the battery indicators and replace the transmitter batteries if necessary.


Adjust the system gain on the front of the receiver. Ensure the output level on the back of the receiver corresponds to the mic/line input setting of the mixing console, amplifier, or DSP.


Check that all cables and connectors are working correctly.

Interface Locks

The transmitter and the receiver can be locked to prevent accidental or unauthorized changes. A locked feature or button will produce the Locked screen on the LCD panel or the lock icon will flash on a transmitter.

Encryption Mismatch

Re-sync all receivers and transmitters after enabling or disabling encryption.

Firmware Mismatch

Paired transmitters and receivers must have the same firmware version installed to ensure consistent operation. See Firmware topic for firmware update procedure.

Tx Battery Hot

If the transmitter battery does not cool off, the transmitter will shut down. Let the device cool down and then consider swapping the transmitter battery to continue operation.

Identify any possible external heat sources to the transmitter and operate the transmitter away from those external heat sources.

All batteries should be stored and operated away from external heat sources in reasonable temperature conditions for best performance.

Radio Frequency (RF)


If neither blue RF Diversity LED is illuminated, then the receiver is not detecting the presence of a transmitter.

The orange RF Signal Strength LEDs indicate the amount of RF power being received. This signal could be from the transmitter, or it could be from an interfering source, such as a television broadcast. If more than two of the orange RF LEDs are still illuminated while the transmitter is off, then that channel may be experiencing interference, and you should try a different channel.

The red RF LED indicates RF overload. Overloads have the potential to cause interference in multiple system installations. If you are experiencing an overload, turn off the receiver to see if it is causing interference with other components.

The numerical channel select button also turns red to indicate interference.

  • Dim red = Channel is not selected, experiencing interference
  • Bright red = Channel is selected, experiencing interference


  • Perform a Scan and Sync to ensure the transmitter and receiver are set to the same group and channel.
  • Look at the band label on the transmitter and make sure the receiver is set to the same band.

Reducing Interference

  • Perform a group or channel scan to find the best open frequency. Perform a sync to transfer the setting to the transmitter.
  • For multiple systems, check that all systems are set to channels in the same group (systems in different bands do not need to be set to the same group).
  • Maintain a line of sight between transmitter and receiver antennas.
  • Move or point receiver antennas away from metal objects or other sources of RF interference (such as LED walls, computers, digital effects, network switches, network cables and Personal Stereo Monitor (PSM) wireless systems).
  • Eliminate RF overload (see below).

Increasing Range

If the transmitter is more than 6 to 60 m (20 to 200 ft) from the receiver antenna, you may be able to increase range by doing one of the following:

  • Reduce interference (see above).
  • Increase transmitter RF power level.
  • Use Normal mode instead of High Density mode.
  • Use an active directional antenna, antenna distribution system, or other antenna accessory to increase RF range.

Eliminating RF Overload

If you see the red RF LED on a receiver, try the following:

  • Reduce the transmitter RF power level
  • Move the transmitter further away from the receiver—at least 6 m (20 ft)
  • If you are using active antennas, reduce antenna or amplifier gain.
  • Use omnidirectional antennas

Antenna Faults

The Antenna Fault red LED indicates a short circuit condition or excessive load at an antenna port.

  • Check antennas and cables for damage
  • Ensure that antenna ports are not overloaded
  • Check antenna bias voltage setting. Turn off voltage if using passive antennas.
