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.
