1. Will I have a problem connecting the unit in Israel because the electricity there is 220V and not 110v like here?
(On the website it's written that the AC adapter is 100-120V, 50-60Hz, but usually it's written only to reduce purchases of a product from different continents. Most of the companies produce the AC adapters 100-240V cause it's simply cheaper! Is this the case with the slingbox as well?)
2. The NTSC/PAL issue. The broadcasting method in the US is NTSC, in Israel it's PAL. Will I have a problem using the Slingbox Solo in Israel, or the unit supports both options?
Thanks a lot,
The Solo uses a 'power brick' so as long as you buy one that delivers the correct output voltage and current (I can't remember off-hand but it will say on your power supply) then there is no problem.
As the Solo does not have a built-in Tuner it is irrelevant. Although the Composite Input is techically one or the other, in practice you can use either. I have been using a US Slingbox in the UK for years without any problem.
