Hello, before buying, you may want to ask the distributor/dealer
if the hi-fi product comes with a version that accepts universal
voltages, like 100~240V. This will be more convinient.
If not, to prevent your product from getting fried, you must
buying a 240V to ~120V transformer/plug/converter.
You can usually find them at electrical stores/hardware
shops.
A cheap one will cost less than $40, but please read the following
paragraphs first before buying a cheap one
You should take note that as are buying a hi-fi product, these
product usually comes with power amplifiers that are used to power
the speakers, and they will consume power.
Thus, it is important to ensure that the 240V to 120V transformer
that you are buying can handle the amount of power(measured in
watts) the hi-fi set is drawing.
For example, if the hi-fi set you are getting consumes a continuous
power of 200 watts, you should get a step down device that can
handle 200 watts of continuous power. You can damage the
transformer if you are using a transformer that is only rated for
50 watts to do a 200 watts job.
Therefore if i were you, i will first check with the dealer to see
if they have that product that can accept 240volts, to avoid the
troubles
