BUILDING A CUSTOM PROCARD
The 3X and 5X both ship with blank cards which can be assembled to select any frequency you need for your system's design. Each card is built using 4 capacitors and 4 resistors, the value of the resistors determines the operating frequency. The custom cards are also available as model number XM00 from your Authorized Rockford Fosgate Dealer. The following section has instructions on assembling the card. The PC Board is fragile and extra care should be taken to avoid damage.
Items Needed:
1.Soldering Pencil
40 to 60 Watt electronic soldering iron
2.60/40 resin core solder
3.Solder Braid - to keep surface free of excess solder
4.Capacitors - Each card uses four .022∝ F capacitors. These should be metal film capacitors with a minimum rating of 16 volts.
5.Resistors - Each card uses four resistors. The resistance is deter- mined by the operating frequency (refer to the following chart). These can be either 1/8 or 1/4 Watt, 1% or 5% tolerance.
6.Wire Cutters
Refer to the following illustration for component placement. Install the resistors, from the full range face, and fold the leads slightly toward the inside of the board to hold them in position. Solder the resistors in place and use the solder braid to remove any excess solder. Install the capacitors in the same manner. Trim the component leads. Examine the board carefully to ensure there is no solder splashed, paying particular attention to the contacts on each edge. Make sure that the leads do not interfere when plugging the card into the socket.
