The following (numbered) comrols arelocated on the subwoofer's rear
panel, as shown in Figures 1and 2.
(!) LINE-LEVEL INPUT: Stereo line-level inputs to subwoofer. Use
these RCA jacks to connect audio signals from line-level outputs from
an AN receiver/preamp/processor. (seefigure 3 & 4,j_r hook-up)
(_) SPEAKER-LEVEL INPUT: Stereospeaker-levelinputs to
subwoofer. Use theseterminalswhen line-levelconnections are not
availablefromA/V receiver/preamp/processor.
(seefigure 5,fir hook-up)
(_) VOLUME CONTROL: Controls volume levelofsubwoofer. Use
to balance the outputof the subwooferwith the main speaker output.
@ CROSSOVER FREQUENCY: The crossovercontrol allowsyou m
adjust the upper limit of the subwoofer's frequencyresponsefrom 40
to 120Hz. The subwoofer'sresponsewill begin rolling offabove the
set frequency. Set the CROSSOVER FREQUENCY tothe lower
value listed in the main speaker manual.
(_) SPEAKER-LEVEL OUTPUT: Audio loop of stereohigh-level
(SPEAKER-LEVEL)inputs. Use m loop (continue) signalto speaker
connections to the leftandright main speakers.

PHASE: Compensates for havingsubwoofer and main speakersin
different locations. Ideally,subwoofer sound should reachthe
listening position at the sametime assound from the main speakers.
However, if thedistance from the listening position to the
subwoofer, and fromthe listeningposition to the main speakers
differ, the sound fromeachwill reach your earsat different times.
The PHASE controldelays the signal 180 degrees,so the subwoofer
output will blend with that oftbe main speakers. Slidethe PHASE
switch to "180." At the listeningposition, listen to the midbass
output. If itsounds weak,set PHASE back to "0."
POWER LED: Powerindicatorlamp. Glows greenin "AUTO
ON" mode ifaudio signalispresent. Glowsred in both "OFF"and
