I've got an amp module for my PRX900 series subwoofer, but it does not match my model type. Is there any way to reprogram the amplifier?
The PRX900 series subwoofers are sharing the same amp module (5135054-00 or 5137452-00 depending on your location), but they have different firmware versions for the PRX915XLF and the PRX918XLF built in version. If you have received a spare part for your powered speaker and the pre-set firmware version does not match the speaker model, follow the steps below.
- Press and hold the "MAIN/MENU" and the "POLARITY" button until the LCD screen powers off.
- Once the speaker reboots, select the correct model with the "MAIN/MENU" encoder (PRX915XLF or PRX918XLF).
- After the selection is made, the LCD will return to its default screen showing the correct speaker model.
Caution:
Selecting the incorrect speaker model could cause damage to the amplifier or drivers. Please ensure the correct model is selected!
