CONTROL DESCRIPTIONS
ATTENTION! Each subwoofi.r has speaker-level and _e-levd input
connections¢choose only one optionfor hook-up. DO NOT USE
BOTH INPUT CONNECTIONS AT THE SAME TIME!
The following (numbered) comrols are located on the subwoofer's rear
panel, as shown in Figures 1 and 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: Stereo speaker-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 outputof the subwoofer with the main speaker output.
@ CROSSOVER FREQUENCY: The crossovercontrol allows you m
adjust the upper limit of the subwoofer's frequency response from 40
to 120Hz. The subwoofer's response will 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 leftandright main speakers.
(seeflgure 5,for hook-up)
_) LINE-LEVEL OlYl'PUT (LW-10/12*, HT-S10MI2A): Useto loop
the full-rangeline-levdsignalback to the receiver/preamplifier/amplifier
fordistribution to mainspeakers. Referto the owner's manual provided
with yourreceiver/preamplifier/amplifier.(seefigure4,fbr hook-up)
0 LINE-LEVELOUTPUT (HT-SI5A & LW-15*): Use to loop

PHASE: Compensates for havingsubwoofer and main speakers in
different locations. Ideally,subwoofer sound should reach the
listening position at the same time assound from the main speakers.
However, if the distance from the listening position to the
subwoofer, and from the listening position to the main speakers
differ, the sound from each willreach your earsat different times.
The PHASE control delays 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 it sounds weak,set PHASE back to "0."
POWER LED: Power indicatorlamp. Glows green in "AUTO
ON" mode if audio 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 if an audio signal
is present and willautomaticallybecome inactivewhen there is no
audio signalpresent afterapproximately20 minutes. In the "OFF"
mode, power isshut offto the amplifier.
