velodyne spl 800 voltage

[simone_s]

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

🙂

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).

hi

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.

 

[simone_s]

sure

I have asked velodyne before buying the sub.
They told me there was no problem to modify voltage to 230v and that was confirmed buy the "unofficial" service center here in italy. In most of subs the job it's quite easy,in this velodyne they told me they need a sort of schematic. that's all i know.

Ok, we need detail shots of these areas...

 

[simone_s]

thank you pinkmouse

Here are two details, if you need later i can take better pictures

hello

thats a switchmode psu.

if it's half bridge-type, with voltage-multiplier for 115V, then you can easily convert it to 230V mains voltage.

 

[simone_s]

easy?

Hi,
you are telling me it's easy...hmm...just wondering why my unofficial service center is not able to do it and why velodyne confirms that it's easy but a sort of schematich is nedeed anyway..

I wrote this:

So only in that case the convertion is easy. If its not a half-bridge (and multiplier for 115V) SMPS, that's not easy anymore!

Hi simone_s,

I am not trying to be rude. with all that you are showing us, it seems that you are not too familiar with these stuff. Stay out of it. Do yourself a flavor. Go to a electronic store, tell them what trouble you are in. I think the salesman can give you a solution (the AC-AC transformer 230V-117V) that gives you and your amp. a peace of mind. DIYers usually begin their voyages with some blown-out stuff, not an expensive or well-working equipment.

One last word, don't forget to tell the salesman what input rating of your amp. is : the 999VA label at the back of your amp, not the output audio power of it.

hi

HI big panda,
you are right...i am totally not familiar with this kind of stuff...
never thought about doing the job by myself...just wondering if one of you had the schematics my local service center needs.
About transformer i would avoid it...

thanks anyway
Simone

it's a class d amp with a switching p/s as part of the circuit
