Using a damp rag or paper towel wipe away any glue squeeze-out on the outside of the enclosure (excess glue on the inside is fine).
  • Page 5: Crossover Assembly

    Crossover assembly: 7) Begin by preparing the input, woofer, midrange, and tweeter wires. Cut one 8" piece of 16 AWG 2-conductor Wire Red/Black (N) and label this wire "input". Then cut two more 12" pieces of 16 AWG 2-conductor Wire Red/Black (N) and label these "woofer" and "tweeter".
  • Page 6 Strip approximately 1/2" of insulation from only one end of each of the wires you cut in step #7 and make sure the strands are tightly twisted together. Using a soldering iron apply heat to the stripped ends and tin the bare copper as shown below. Note: When tinning the ends only apply gentle pressure to the wire to prevent flattening the twisted strands.
  • Page 7 12) The C-Sharp Crossover Printed Circuit Board (Q) is labeled to make it easy to locate and install the corresponding components and cables. Working from one side of the board to the other, insert the leads (or wires) through the corresponding holes in the crossover board and solder into place. Tips: 1) Elevate the board a couple inches so you will not have to deal with trimming the leads until the crossover is complete.
  • Page 8: Final Assembly

    Final Assembly: 15) Insert crossover through woofer hole of both enclosures and glue crossover to the bottom of the enclosure (polyurethane glue, high temperature hot glue gun, or epoxy is recommended). Make sure the crossover with the 2-pin amplifier output connection is installed in the master (right) speaker enclosure.
  • Page 9 19) Set the included gasket in place on the back of the LP40PA plate amplifier. Position the LP40PA amplifier module near the simplifier cutout in the back of the master (right) speaker. Plug the 2-pin speaker wire connection and the 4-pin control panel data cable into the appropriate connectors on the LP40PA amplifier board (these connectors are keyed and will only go in one way, do not try to force the connector into place).

  • Page 14 Amplifier Installation (Master): A 1-3/4" H x 2-3/4" W cutout is required to install the amplifier module. Make sure that the amplifier is located where it will not interfere with the crossover. Control Module Installation (Master): A 25/32" H x 2-19/32" W cutout is required to install the control module.
