The Challengers come with an HDMI switch which allows selecting which input device (DVD, game console etc...) is displayed on each of the three televisions. The HDMI switch controls 2 input devices and 3 or 4 televisions. I'm not sure whether or not the smaller class A units include the HDMI switch in their AV package. Technically you shouldn't need one, however, not having one may limit what can be viewed on what television.
