Turn off all power to your subwoofer and other equipment before making any connections.
Installation using speaker level inputs (Figure B).
Off: Turns the unit off. |
On: Turns the unit on regardless of whether a signal is present or not. |
2) Subwoofer crossover: This rotary control adjusts a variable low pass filter to |
set the upper frequency at which the output of the subwoofer begins to |
Continuously variable from 50Hz to 150 Hz, it matches the upper frequency char- |
acteristics of the subwoofer to the low frequency response of the main stereo |
speakers. Recommended setting: |
3) Line level input: These RCA phono jacks accept a line level full range signal |
from the preamplifier output of a receiver or preamplifier. This full range signal is |
processed and amplified to power the subwoofer. |
4) Speaker level input: These spring loaded terminals for speaker wire accept a |
stereo, speaker level, full range signal from a receiver or power amplifier. This |
signal is processed and amplified to power the subwoofer. |
5) Fuse: For continued protection replace fuse with same type and size listed. |
6) Level control: This rotary control adjusts the level of the subwoofer and is used |
to balance its volume with that of the main stereo speakers. |
7) Status LED: This light emitting diode shows the status of the subwoofer elec- |
