EXPLANATION OF FEATURES AND CONTROLS

1) Power Switch: This two position switch controls the power status of the sub-

woofer.

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 roll-off.

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

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-

tronics. "Red" indicates that the amplifier is plugged in and the power switch is

on.
