4.6.6
November 5, 2021

New Features

  • Disable USB Mute Sync communication with software codec platforms

Improvements

  • Improved gain, audio routing, and EQ contour settings when using the Designer “Optimize” feature with P300 and Shure microphones
  • Bug fixes

Known Issues

  • Shure Audio Encryption is not backwards compatible; all devices must be on version 4.1+ firmware to use this feature
  • P300 Shure Audio Encryption sometimes has brief crackling sound on audio after muting
  • Shure Update Utility and Designer may not allow downgrading of new P300s shipped with 4.2.7 or higher due to a platform update to support future functionality and USB improvements
  • P300s with firmware 4.3 require Designer versions 4.3 and higher and will NOT be supported in Designer versions 4.2.1 and earlier.
  • P300 firmware periodically add new properties. The P300 may become undiscoverable if downgrading to firmware without the new properties and may need a factory reset to become discoverable.
  • When attempting to load the device’s web page after using SUU to upgrade or downgrade between MXA 4.3 and earlier releases, the browser may appear to be stuck on the “Loading” screen with the progress bar continually moving. This will typically happen if two upgrades or downgrades are performed within a one-hour period.
    • Workaround: hold your Shift key and click the Refresh button in your browser (or press Ctrl+Shift+R [Win]/Ctrl+F5 [Win]/Cmd+Shift+R [Mac]; note the keyboard shortcut doesn't work on Safari)

4.1.11
February 11, 2020

New Features

  • Support for Dante Domain Manager
  • Dante Device Lock
  • Direct outputs from channels 1 – 8
  • Now has 8 Dante outputs (was 6)
  • Component user interfaces (web UIs) for the P300 and ANIUSB-MATRIX will be feature-reduced to support basic troubleshooting of network and device settings only. Designer version 3.2 will remain available for download to support legacy 3.1.x and 4.0.12 devices. 

    NOTE: Please ensure that field technicians and anyone providing in-field support on these devices downloads and installs the latest version of Designer. Device configuration and optimization capabilities will be minimal without Designer.

Improvements

  • Additional USB mute sync compatibility
  • Additional TPCI commands
  • For enhanced security, first-time user interface access will prompt the user to set up a passphrase. Users have the option of continuing without a passphrase, allowing for Shure Designer configuration software to securely configure the device within a location.
    • Passphrase length must be at least 8 characters up to a maximum of 64, all characters allowed
    • The passphrase may be disabled after the first login
    • Downgrade caution:
      • After the 4.1.37 upgrade, the device’s new passphrase (and/or its audio encryption passphrase) might exceed the allowed length of its prior firmware version. In that case, downgrading requires the following procedure to ensure passphrase compatibility:
        • Prior to downgrading, log in and disable the passphrase(s) or the change the passphrase(s) to the character length allowed by the prior firmware to be downgraded to.
        • Perform the firmware downgrade. Enable passphrase(s) as desired.
    • Using Designer software:
  • When multiple devices at different firmware levels are put into a location using Shure Designer software, the location passphrase for those devices must abide by the length and character set limitations of the older firmware. Advice: Update all devices in the location to the latest firmware in order to use a more robust passphrase.

Known Issue

  • Shure Audio Encryption is not backwards compatible; all devices must be on version 4.1 firmware to use this feature
