How to update the Prism Sound Lyra 2

Install the latest Prism Sound control app and driver package for your computer first (an older Control Panel may fail to load newer firmware), then download the Lyra firmware file that matches your unit's serial number (LX9 or LX4, as noted on the downloads page). Connect the Lyra 2 to the computer over USB and open the Prism Sound USB Audio Control app. Save your settings and turn off any speakers or amplifier connected to the unit. Remove power from the Lyra, press and hold the volume encoder pushbutton and the standby button, restore power and release the buttons: the front LEDs stay off (bootloader mode) and the app shows the bootloader dialog. Click Browse, select the firmware file, click Load and wait for the progress bar, then click Launch to reboot with the new firmware. Settings return to factory defaults after the update, so reload your saved settings.
