I just recently acquired a pair of DSP5500 (18 bit version) speakers from the US. However, I'm in Australia where we use 240V power. Does anyone here know how to go about converting the power supply over from 115V to accepting a 240V supply?

Is it simply a case of rewiring the supply? Will any parts need to be sourced? Or would it be safer and easier to unbolt the component holding the power supply and take it to an electronics repairer? I've have lots of experience with building circuits, mainly mods to Naim gear, but not Meridian. With instructions or a diagram in front of me, I should be capable of undertaking the task.

I'm currently using a 2.5amp step -down transformer, but this method is probably not helping the overall performance of the system. Plus, it would be nice not to have the step-down transformer to worry about.

Hi Zam,

You'll need to exchange the existing 110V transformers for 240V versions.
There's no way of rewiring the exisiting ones.

Cheers,

Rick

Hi Rick,
Is it just the transformer? Nothing else (like rectifiers or electrolytics)?

Just the transformer and a change of mains fuse.

OK, do you know the type? Would Farnell have them?

Most of the toroids Meridan used were British made. By a firm close to the factory.
They did use other suppliers though. You will have to find the spec if you want a non original.

OK, so here's one for you, should I leave it alone and continue to use the step-down transformer, maintaining the original 'Meridian' transformers. Or do I get an equivalent 240V version supplied to spec (non-original), and do without the step-down?

Hi,

AQ wise I don't think it will make any difference either way.

Meridian sourced transformers will be very expensive.

Non-Meridian sourced, you will have problems getting the 'spec', find a 'std' equivalent or the cost of having some custom wound.

I'd stick with the step-down transformer and enjoy the music.

Regards,
Carl

Some people have reported that the use of a stepdown transformer can harm the 'dynamics' of music. YMMV.

Hi Zam,

It's just the transformers which are required, and the fuses, as Carl has already mentioned.

My advice would be to swap to Meridian supplied transformers for the best performance, but if this is too expensive an option I'd continue with your outboard step-down transformer rather than look to come up with third party supplied transformers.

I'll PM you the Meridian transformer costs.

Cheers,

Rick

I ran a pair of 240V DSP5000's for several years with a big step up transformer (110 to 240V) and they worked just fine.

I subsequently bought a 240V DSP5500HC and I installed a 110V transformer which was kindly donated by George (the Fiddler). Somewhere in the house I should have the 240V transformer that I removed and I could make that available to you for the cost of shipping (which might not be insignificant to Aus). That would get you half way towards the pair of transformers that you need.
