We do sell the amplifiers from our WorxAudio lineup as a separate rack-mountable unit but we do not sell them direct to the public.
You will need to contact a Presonus authorized dealer to purchase them. If you are not certain where to find an authorized PreSonus Commercial dealer please email us at [email protected]
with contact information and we can help you find someone.
