velodyne spl 800 voltage

simone_s · 6th February 2005, 03:57 PM

Hi guys,
I am new here, and need help from you.
I bought a velodyne spl 800 subwoofer in the USA, now i am back in italy and want to change voltage from 117v to 220/230v.
The local official dealer does not want to make this work cause it's against its business (here an spl 800 costs about 2500$).
I brought the sub to an unofficial service center but they were not able to do the work cause they don't have the ampli and transformer schematics .
Anyone of you can help me?
Thanks

Simone

Does the transformer have multiple primaries?

It may be easy to modify if it has an extra tap for 220v input.. but maybe use a variac do protect the electronics

Watch out for component voltage ratings as well (before the transformer).

Thanks for your answer thomas.
Well, american velodyne service center assured me that's an easy job to modify voltage, requiring to change no components and that's what also told me the "unofficial" service center here in italy.
The thing i need it's the schematic and possibily the instructions to do the job. American velodyne service center does not want to give it to me...
Don't really know if the spl use a variac, sorry.

Try to take a picture of the primary side of the transformer. That's where makes 117V different from 230V. If you are not too sure, try to get an external AC-AC transformer 230V-117V that can step down your local supply to 117V as required by the amp. Safe and easy. Works for people who are not too familiar with these things.

I don't know about those US makes. The amp. I have seen (although not much) can usually adapt to different AC supply voltages. Maybe yours is intended for US local use only? Should have considered that issue when you buy ANY electrical appliances for non-local use.
