  • Make sure your wireless audio device is powered on and connected to your network.
  • Open the Play-Fi app (PC/Android/iOS) and access the setting menu (gear icon). Look for an option called “About”. Depending on the version of the Play-Fi app, you may need to access a submenu which may be labeled something like “More Settings...”.
  • All connected Play-Fi devices will show the Play-Fi firmware number labeled “CAP: “

MartinLogan firmware version (Crescendo)

  • Turning off your computer's Wi-Fi.
  • Attach Crescendo directly to the computer using an Ethernet cable.
  • Turn Crescendo off and on using the Power button on the back of the speaker.
  • It may take additional time for your computer to establish an Ethernet connection with Crescendo. Once established, the Setup and Status LED on back of Crescendo will turn solid green.
  • Open a browser and enter "169.254.1.1" as the URL. 
  • Click the “Firmware Update” button.
  • The MartinLogan firmware version will be labeled: “Current Firmware Version”. The number in the middle is the current version. For example, s9329.21.100 = Firmware revision 21.
