The effectiveness of 200V power supply for audio-visual related equipment has recently been acknowledged, and we recommend the use of such power. With our Isolation Transformers, we ensure manufacturer-based support for AC200V power input (excluding transformers for musical instruments, and AVT-64SP/82SP), so customers wishing to modify a product after purchase should return the product (including the attached cable) to us.
It will normally take us 3 to 5 working days to modify and return the product. The modification charge will be \10,000 including exchanging and modifying the 200V power outlet plugs.
If an additional transformer is required, this will cost \5,000 per transformer.
