CONTROL DESCRIPTIONS
ATTENTION! Each subwoofi.r has speaker-level and _e-levd input
connections¢chooseonly one optionfor hook-up. DO NOT USE
BOTH INPUT CONNECTIONS AT THE SAME TIME!
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 these terminalswhen line-levelconnections are not
availablefrom A/V receiver/preamp/processor.
(seefigure 5,fir hook-up)
(_) VOLUME CONTROL: Controls volume levelofsubwoofer. Use
to balance the output of 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's responsewill begin rolling offabove the
set frequency. Set the CROSSOVER FREQUENCY to the 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 left andright main speakers.
(seeflgure 5,for hook-up)
_) LINE-LEVEL OlYl'PUT (LW-10/12*, HT-S10MI2A): Useto loop
the full-rangeline-levd signalback to the receiver/preamplifier/amplifier
fordistribution to mainspeakers. Referto theowner's manual provided

PHASE: Compensates for having subwoofer and main speakersin
different locations. Ideally,subwoofer sound should reach the
listening position at the same time assound from the main speakers.
However, if thedistance from the listening position to the
subwoofer, and from the listeningposition to the main speakers
differ, the sound from each will reachyour earsat different times.
The PHASE controldelays the signal 180 degrees,so the subwoofer
output will blend with that oftbe main speakers. Slide the PHASE
switch to "180." At the listening position, listen to the midbass
output. If itsounds weak,set PHASE back to "0."
POWER LED: Power indicatorlamp. Glows greenin "AUTO
ON" mode ifaudio signalispresent. Glowsred in both "OFF" and
"AUTO ON "modes if receivingAC power, and audio signalisnot
present afterapproximately20 minutes.
POWF_: Two-position power switch. In the "AUTO ON" mode,
the subwoofer's amplifierisautomaticallyactivated ifanaudio signal
is present andwill automaticallybecome inactive when there is no
audio signalpresent afterapproximately20 minutes. In the "OFF"
mode, power isshut offto the amplifier.
