CONTROL DESCRIPTIONS
®
PHASE: Compensates for having subwoofer 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 the distance from the listening position to the
subwoofer, and from the listening position to the main speakers
differ, the sound from each will reach your ears at 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."
®
(_) VOLUME CONTROL: Controls volume levelofsubwoofer. Use
to balance the output of the subwoofer with the main speaker output.
POWER LED: Power indicatorlamp. Glows green in "AUTO
ON" mode if audio signal ispresent. Glows red in both "OFF" and
"AUTO ON "modes if receivingAC power, and audio signal isnot
present afterapproximately20 minutes.
@
@ CROSSOVER FREQUENCY: The crossovercontrol allows you m
adjust the upper limit of the subwoofer's frequency response from 40
to 120 Hz. 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.
POWF_: Two-position power switch. In the "AUTO ON" mode,
the subwoofer's amplifierisautomatically activated if an audio signal
is present and will automaticallybecome inactive when there is no
audio signal present afterapproximately20 minutes. In the "OFF"
mode, power isshut offto the amplifier.
®
VOLTAGE SELECTION (LW-X Models only) : User-switchable
voltage selectionfor use with 115 or 230 volt AC. Auentiom A//
suhomofer mndds comefrom thefactorypreset to 115 volts. To select
a different voltage,use a flat-headscrewdriver to reposition the switch
to the desired voltage. WARNING: Severedamage may mult from
improperly sekcted voltage. Make sw_ you know the voltage
requirement of tl_ _untry you are in beforeattempting to connect
this mhomofer toACpower. Obwrveproper fuse rating (type and
value) @for sde_cd voltage®.
@
POWER CORD RECEPTACLE: Connect IEC cord to this
receptacle. If the cord supplied does not fit art availableAC outlet,
purchase the correctAC cord from your audio dealeror an electrical
supply store.
ATTENTION! Each subwoofi.r has speaker-level and _e-levd input
connections¢choose only one option for 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.

PLACEMENT
Cerwin-Vega Subwoofer Systems can be positioned anywhere on the
room's floor. For best performance however, place the subwoofer nearthe

by the subwoofer. If your television produces distorted colors a)qer
installation, this can be corrected by moving the subwooferfurther
away from the television until normal color is returnea_
