battery and a 3A Fuse should be installed within 18” of the battery terminal. The RMT wire should connect to the turn-on
lead of your source unit.
5. Connect all line level inputs and outputs using high-quality RCA cables. Recheck all connections prior to powering up
Set all level controls to their minimum positions and set all crossover control switches level with your frequency
position.
