You need one extender for each separate place where you
have equipment. You connect the extender to each piece
of equipment using an IR Emitter cable - maximum of 8
pieces of equipment per extender.
OR
You could put a Xantech amplified connecting block on each emitter port of the extender and run 4 zones, one zone for each port.
