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.
7. 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.
The volume control should be at the minimum setting (all the way counterclockwise) before plugging
the amplifier into an A.C. wall outlet.
