USING THE XCARD

The crossover functions are controlled through the use of an XCard and can be set for high-pass, low-pass or full range operation. The XCard shipped with your amplifier is set for Full Range. Each crossover card has two faces: one face operates Full Range, the other has arrows to indicate the edge for selecting HP (high-pass) or LP (low-pass) operation. Orient the card with the desired operating edge, indicated by the arrow, toward the socket terminals inside the amplifier. Firmly, but carefully, plug the card into the socket.
