[QUOTE="archive10, post: 894510"] Why are you using a quattro in your setup? Quattro is four individual fixed outputs: Horizontal/Low, Horizontal/High, Vertical/Low, Vertical/High. Quad is a quattro PLUS a switch in front, that can be used to select which of the four combination you want on a specific output. Modern LNBs (single, dual, quad) include the switch, and therefore works with modern Sat receivers. In most domestic installations, your receiver signals the switch in the LNB as to which combinations is required on the sat input. If you use a quattro, it will - however - still work for the transponders that happen to be on the combination of the output connected to your receiver input. So, if you connect Low/Horinzontal output to input on a single tuner box, it will work for about a quarter of the possible transponders (the quattro ignores the tone signalling).
