Hi Kittu, Thanks for the fast response... How do I locate Hassan Khani in this forum. I am in Hyderabad and for now not planning to go to Bangalore. Are you suggesting on getting it shipped to Hyd?.
As I said before, 1911 is a non-US model number and, depending upon where it is sold, will carry 2220-240V capability. The x91 series are US centered, and will accept only 110 volts.
If you see a Denon 1911 in an US centric site, and it says 220-240 Volts, please call up the site to confirm. Some of the sites may cut and paste images without realising what they are doing.
Cheers
Many companies provide a numbering system specific to a region. While the regular numbers for Denon processors are 1911, 2311, etc, in the US they are numbered as 791, 991, etc. These numbers will have only 110 volts, and you would certainly need a step down transformer.
Cheers
