A:
All UN, PN and LN units (North American Units) will only have support for NTSC/ATSC/QAM broadcasting systems and NA power systems. Since the NA TVs will not accept a PAL signal or Non-NA voltages, you will not only need a converter for the broadcast, but also for the power if you would like to use the TV in a PAL country. Unfortunately, I will not be able to recommend a specific converter since Samsung cannot offer support for products we do not manufacture.
Additionally, the UN46EH5300 will not offer Voice Controls.
