Updating the Firmware
The current firmware version (1.3) is installed on pedals manufactured after May 1, 2022. If you bought the pedal on
an earlier date, we advise that you update the Prism II firmware to the latest version presented on this page.
Please note that updating the firmware may alter the pedal’s sound settings. If you’re actively using the pedal in a
project right now, it may be advisable to only update the firmware once the project is over.
NB! An interrupted firmware update can render the pedal unusable. If something goes wrong during the update, the
pedal will most likely need to be serviced by Shift Line’s qualified specialists. Please use the feedback form if you
experience any issues with the firmware update.
PLEASE READ THE INSTRUCTIONS IN FULL BEFORE STARTING THE UPDATE!
Follow these steps one by one:
1.
Disconnect all cables from the Prism II, then connect them in the following order:
1.1.
First, connect the pedal to your computer via a microUSB cable.
1.2.
Next, connect the power supply to the pedal.
2.
Both LEDs should now be glowing blue: this means the pedal is ready for the firmware update. If that’s the
case, you can proceed to the next step.
3.
Open the PRISM 2 drive and delete the AFXSETUP folder (remove it from the bin, too).
NB! If you need to save a previously edited config file, save it to a different destination on your computer
before deleting the AFXSETUP folder!
4.
Copy the update file (
p2update.bin
) to the root folder of the PRISM 2 drive.
NB! Do not rename the update file.
5.
After the files have been copied, safely eject the PRISM 2 drive from your computer.
6.
Disconnect the cables in the following order:
6.1.
First, disconnect the power supply from the pedal.
6.2.
Next, disconnect the microUSB cable.
7.
After that, reconnect the power supply to the pedal.
8.
The pedal will start the firmware update as soon as the power supply is plugged in.
Do not disconnect the power supply from the pedal until the update is finished!
The firmware update takes two minutes to complete. The Prism II indicates various stages of the update
process by LED colors. When the update is over, the pedal goes to a bypassed state and indicates the tempo
with the TAP LED.
After all of the above steps have been completed, the pedal is ready for use again. You can verify the success of the
update in the config file. To do that, open the AFXSETUP folder in the PRISM 2 drive and open the PRISM2.SET file
with a standard text editor. The firmware version is displayed in line 3:
