这是大河厂家技术人员关于如何改变电压的解答,自己翻译去:
It's very easy.
On the back of the unit is the power entry module, this is where your power cord plugs into the preamp.
The bottom half of the module contains the fuse and the voltage selector card.
There is a small opening in the plastic face, you should be able to read the numbers "110" in the opening.
You can pry this piece out of the module with a flat bladed screwdriver. Now you can see the fuse and the voltage selector card. Slide the card out of the holder, turn it over and slide it back in, now the opening will show "220".
Change the fuse from a 400mA slo-blo to a 200 or 250mA slo-blo type and reinsert the plastic carrier back into the power entry module.
Plug in the correct power cord and you're set.
It takes longer to describe than it takes to do it.
