Alesis Power Supply Adapter for SR16, Trigger IO, MMT-8

This replacement power adapter is compatible with the Alesis SR16 (9V Version), Trigger IO, and MMT-8 (not included).

Alesis has discontinued the original P3X power supply. We have sourced a high quality replacement that is of the exact same spec and build quality as the original Alesis P3X. We have used this power supply as a replacement for many years, and it works flawlessly as a replacement PSU. There are a lot of cheap PSU's out there, but they are low quality, which affects the performance of your unit, resulting in inferior sound quality, noise, and worse, taxing your unit beyond the original specifications.

Please Note: Newer Alesis SR16 drum machines now use a DC power supply - please check your unit's power requirements before ordering this power supply!
