EXPLANATION OF FEATURES AND CONTROLS
Refer to Figure A
1) Power Switch: This two position switch controls the power status of the sub
-
woofer.
Off: Turns the unit off.
On: Turns the unit on regardless of whether a signal is present or not.
2) Subwoofer crossover (Freq): This rotary control adjusts a variable low pass fil
-
ter to set the upper frequency at which the output of the subwoofer begins to roll-
off. Continuously variable from 50Hz to 150 Hz, it matches the upper frequency
characteristics of the subwoofer to the low frequency response of the main stereo
speakers. Recommended setting: 120Hz-150Hz.
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 (high 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 (Gain): 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
-
tronics. "Red" indicates that the amplifier is plugged in and the power switch is
on.
