Hi guys, I got the VIZIO SB3821-D6 a year ago from ebay and it was quite a good soundbar.
One thing i realised after reading here is that the voltage might well be 120V (US market only) but the unit is well and fine after a year of use..... Should I be worried and get a step down transformer still?
I couldn't find anything about voltage on their website and thrown away the box as well.. last thing to do is to email them actually..
If you been running for 1 years sound like the sound bar support 110-230v power. Otherwise it should be blow (fuse and internal power) on your 1st power on.
