NOTE: The crossover has a parallel and a bi-wire/bi-amp input. To access these settings remove the top cover of the crossover. This is accomplished with a small flat head screw driver. There is a small notch just to the left of the output plug on the crossover. Insert the screwdriver and gently pry. Be very cautious not to insert the screwdriver too far or you could cause physical damage to the board and void your warranty. The parallel/bi-wire switch is right next to the input plug. When selecting parallel, it does just that, wires the input in parallel (meaning the positive terminals are common and the negative terminals are common). You would use this selection when using a single channel to power the tweeter and the mid/woofer. It does not matter which positive and which negative you use since they are wired in parallel, although the tweeter positive and woofer negative are on opposite ends of the plug to make the wiring easier. Parallel wiring is also probably the most popular wiring method.
The bi-wire/bi-amp selection is for using two separate channels for powering the tweeter and the mid/woofer. When using this selection one channel would use the positive and negative for the tweeter and the other channel would use the positive and negative for the mid/woofer. There is also a tweeter level switch for adjusting the tweeter. Moving this adjustment will change the output gain of the tweeter. Where the adjustment should be depends on the location of the tweeter and your preference. Adjustments can be made from +3dB to -6dB in 3 dB steps. Tweeter phase can be changed by reversing the polarity of the tweeter output wire connections on the crossover. If the tweeter is within 6" of the woofer center the tweeter should be in phase with the woofer. If the tweeter is further than 6" from the center of the woofer, both in phase and out of phase should be tried to see which is best.
