Rockford Fosgate 360.6 manual Us I N G T H E Xcard, Customizing T H E Xcard, 3386, 7234, 2πfoc

US I N G T H E 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 installed in 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.

CUSTOMIZING T H E XCARD

The crossover point can be altered by changing all 4 resistor values. Use the following formula to select the appropriate resistor value to be placed on the XCard.

3386	= R (in kΩ) for .047μf cap
fo
7234	= R (in kΩ) for .022μf cap
fo
The actual formula is:
R =	1
		R1
	2πfoc

Where: R = Ω

fo = desired crossover frequency c = capacitor in farads

ex: .047 x 10-6for .047mf cap
