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 multi cabinet array you will need to separately download the Microcontroller firmware to the Master (0) module and to
each Slave module. Use the Unit DIP Setting arrows(outlined in red below) to select the correct module.
