I've been looking over the new $1500 Rotel RSP-1066 pre/pro and today noticed that Rotel specs the component video switching bandwidth as only 3-10Mhz -3dB. Not only is this woefully insufficient to pass a 1080i HD signal, it even falls short of fully passing a 480p signal. 480p progressive output from a DVD player requires 13.5Mhz, and many people recommend a bit over that to fully pass a sharp image. That is, it is better if the -3dB point is a bit higher than 13.5Mhz.


If Rotel's spec is real, this is a serious shortcoming for just about anyone wanting to use it for component video switching - unless you plan on using only interlaced 480i video. Rotel claims that 10Mhz is sufficient for 480p, and perhaps it is for most people and TV sets. But it is hard to believe that any new pre/pro would use components of such low quality, heck, the $1000 Denon 3802 receiver supports 27Mhz through its component inputs. While 1080i theoretically requires 37Mhz, 27Mhz is sufficient to exceed the resolution limits of many HDTV sets.


I'm very surprised that Rotel's engineers signed off on this spec.
