One TX-2500 is connected to each TV.  The TV Audio output is connected to the transmitter's left input (for 2.3MHz) or the right input (for 2.8MHz).  By alternating channels on each of the transmitters, enough separation is created so programs don't interfere; i.e. TV#1 on 2.3MHz, TV#2 on 2.8MHz, TV#3 on 2.3MHz, TV#4 on 2.8MHz and so-on.
