5. Crossover:
This button allows the amplifier’s internal low-pass filter to be
defeated when using an external crossover, or when the crossover is not
needed. When defeated (off), the subwoofer output will play the full-range
of the audio signal. This button has no effect on the high level inputs and
outputs shown in figure 2, #10 and #11. The high level output (figure 2,
#10) has a 100Hz high pass filter and is not adjustable or defeatable.
6. Crossover Frequency Control:
The variable crossover frequency
control allows you to set the point of the low-pass frequencies being
reproduced by the amplifier anywhere from 40Hz-180Hz. Try an initial
setting of the crossover frequency control at the midway (12 o’clock)
setting. Increasing the crossover frequency will produce more mid-bass
output from the amplifier.

Master Volume Control:
This dial allows you to adjust the output level
of the subwoofer to match the audio system. For an initial setting, turn the
volume control up one quarter of a turn (9 o’clock) position). The volume
control may be adjusted while listening to match the subwoofer output
level with the rest of the system.
REMINDER
–The volume control should be at the minimum setting (all the way
counter-clockwise) before plugging the amplifier into an A/C wall outlet.
