Hi all,

I recently bought a Minilogue in Tokyo, but I live in India and wanted to check a couple of things before I start using it.

1. Is the power supply that comes with the Minilogue already protected for global voltages or do I need to buy a voltage transformer? The power here is AC 220-230 V usually but on the adapter I have it says AC 100 V or DC 9 V.

2. I have been reading that it requires center-positive plug points, what does this mean?

I have an Electribe 2 which I got in the UK (Same voltage as India) and a couple of other smaller synths bought in India, all of which I just plug in and play without any issues, so advice or answers would be much appreciated. Really wouldn't want to short the Minilogue after carrying it so far!

Thanks

Mains power supplies catering for a wide input voltage range would normally specify that range somewhere on the ratings label e.g. 100-240V, although I notice on a Toshiba laptop supply there is a box indicating AC 100V 1.3A, for the Japanese market, but elsewhere on the label it says 100-240V~1.3A 50/60Hz, and this was supplied for, and works OK, on a 230V AC supply.

Check the whole label, including the small print.

If not sure, contact Korg for the correct PSU for your mains voltage.

Thanks for the response.

In the small print on the PSU of the Minilogue it says input 100-240V~ 0.5A, 50/60Hz and output DC 9V, does that mean I am good to go?

On the box though it said AC 100V so I am still not 100% sure.

The mention of 100-240V in the small print means it should be good to go. A manufacturer would get into serious trouble if they put such a specification into a PSU designed to work on and containing components rated only for 100V AC supplies.

As a precaution, you could try plugging the power supply into the mains without the Minilogue connected and leave it like that for an hour or so. If you have a multimeter, check the output voltage on the plug that goes into the Minilogue, with the multimeter set to 20V DC and placing one test lead into the centre connector and the other touching the outer metal part of of the connector. It will probably read a little over 9 volts e.g. 9.5, possibly even 10V. Check that it is still at this value at the end of the test, and that the power supply has not become hot to the touch. If all is OK, it should be fine to plug it into the Minilogue.
