Updating Microcontroller Firmware (Continued)
Step 2: Select Update Microcontroller Firmware and when the window shown below opens select the appropriate firmware file and press
Download. Notice that the window tells you what Microcontroller Firmware version is installed in the loudspeaker. Selecting Download will
install the new firmware in the loudspeaker.
If you are updating a stacked (dual) array you will need to separately download the Microcontroller firmware to both the Master (0) module
and to the Slave (1) module. Use the Unit DIP Setting arrows to select the correct module.
Step 3: Wait for the Firmware transfer to complete. When finished, control will be returned to the dialog window. Select “Done”.
Please be aware that the Mutes and the Analog Input Pad will be On after the update completes and may need to be reset.
