Wiring and Connections
Depending on the installation location, it may be necessary to use a powered FM
antenna to receive clear FM stations.
When an AM/FM tuner has been installed, input #1 will default to the internal tuner and the RCA input
jacks will not be active for source #1. If no internal tuner is installed, the source #1 inputs will be active.
Either way, Source#1 is activated by the top-left button on the keypads.
See "Using the Matrix Keypads" for more details on how to use the keypads.
4. Connect the 75 Ohm FM antenna by pushing the "F Connector" on to the terminal at the back of the
Delta Controller.
5. Connect the AM loop antenna by inserting the stripped wire ends into the spring loaded jacks at the
back of the Delta Controller.
Since this a "loop" antenna, the position of the wires in the jacks does not matter (FIG. 6).
