Open the crossover housing by firmly squeezing the sides
of the top half and lifting it away from the bottom. Using
screws or a wire tie, mount the crossover using the holes
provided. Observing proper polarity, connect the speakers
and amplifier as shown in Figures 8A and 8B. Replace the
cover when you are finished making the connections and
adjustments (see following section).

are wired similarly.
The Power Series component crossover features a
tweeter-level adjustment. The tweeter level may be set to
0dB (flat response), or it may be attenuated by approxi-
mately 3dB to suit the listener’s preference. The factory
default position is 0dB; if this is the desired setting, it is
not necessary to make any changes.
If a reduced tweeter output level is desired, carefully
remove the small plastic jumper from the pins marked
“0dB” and place it across the two pins marked “–3dB”
(refer to drawings below).
