Open Issues:

  • P300 Shure Audio Encryption is not backward compatible; all devices must be on version 4.1+ firmware to use this feature.
  • P300 Shure Audio Encryption sometimes has a 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.
  • P300s with firmware 4.3 require Designer versions 4.3 and higher; not supported in versions 4.2.1 and earlier.
