I recently acquired a couple of fp6400 amplifiers. The Oddity is that these are labeled on the back as the 115 volt version, but there is a piece of Gaff tape with 230v written on it. They all have the 30A locking connectors on them. When I connected one to 30A to 20a plug adapter and plugged it in, it Powers on, but the fuse protection light is on. Could these have been modified to 230v? How can I tell? Additionally, if I do plug it into a 230v line, could I cause serious damage or would the fuse protection activate?

All good now!

I don't know much about that amplifier, but the link below discuss some things you might look for to see if it has been converted.  Hopefully, you didn't but the actual amp being discussed!

It's doubtful since there are 4 in total, but without sending it to a service center, I hope the link to the thread has some valuable information. Thank you!

Anyone have in depth experience with these Lamborghini powered Volvos?

Do NOT plug it into 230V unless you are absolutely sure it's the correct model.  We did that once (mislabeled amp) and created an immediate smoke machine. 

They're good amps still, not my first choice for subwoofer duty.  The lack of universal voltage was one of the small reasons why we switched (to Powersoft and then Linea).

This is my concern as well! I've taken some internal pictures, but I don't see any jumpers, nor do I see any sloppy soldering work to give the indication that it has been worked on. My goal is to confirm that these are usable, then have them serviced. Being that there's only five service centers in the US, and every one of them is over 500 miles away from me, I'd like to know that these are operational beforehand.

Caleb, I thought those amps had over voltage shut down on them?  Kelso, can you share the pictures you took?

That link doesnt work, do you have the permissions set right? 


If you don't want to deal with these amps and would rather get something with autovoltage I will take them off your hands.
