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: 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 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.

PHASE: Compensates for havingsubwoofer and main speakers in
different locations. Ideally,subwoofer sound should reach the
listening position at the same time as sound from the main speakers.
However, if thedistance from the listening position to the
subwoofer, and fromthe listening position 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. Slide the PHASE
switch to "180." At the listeningposition, listen to the midbass
output. If it sounds 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 amplifierisautomatically activated ifanaudio signal
is present and will automaticallybecome inactive when there is no
audio signalpresent afterapproximately20 minutes. In the "OFF"
mode, power isshut offto the amplifier.
