I have a 120v Nautilus 61at but I am moving to Portugal soon. It is labeled 120v on the rear, does anyone know if it will actually switch voltage internally automatically (despite the labeled voltage), or do I need an outboard voltage transformer? Thx

The days of mains supply voltage specific switched mode power supplies is a thing of the past in Korg products. The Korg M1, and other products of that era, had them, but not any more. Generally Korg stuff is shipped with universal power supplies, and the Nautilus seems likely to be no exception. As you probably noticed, the Nautilus specification unhelpfully makes no mention of input supply voltage range. It should do so really. The wording for the Nautilus mains supply spec is exactly the same as that given for the Kronos, and the Kronos definitely does work across the full mains voltage range (110-230V, it was probably tested over the even wider range of 90-264V A.C.).

With the above in mind, plus the fact that the power supply in the Nautilus uses a transformer that is used in other SMPSUs also described as having wide-range inputs, it should be safe to plug it into a 230V supply.

Hi, I have the Nautilus 61 key 2023.. I travel a lot, usually with a voltage convertor.. This thread intrigued me, and so i took the base plate off of my keyboard, and found that the voltage regulator inside my USA 120v rated keyboard is actually rated 100-240v 50/60hz.. So now i am confident to be able to take this keyboard to Japan (100v) and the UK (240v) without a convertor.. (side note.. though the keyboard says 'made in Japan', most of the components inside are labeled 'made in China'.. A little honesty from Korg would go a long way, though i do LOVE the sounds this keyboard puts out) I have photos of the transformer label inside the keyboard if any one needs them as confirmation.
