How to get 5 receivers working at once.

[A_Noland]

I have a Sw64 using 3 of the wires. How can I add a 921 to it. Can I use one of my old SW21 and split one of the outputs from the sw64?

The sw21 is a 2 into 1, it works backwards from a splitter. To do it right you need another 64, or loose the whole legacy thing, and update to two DP34's.
