Control Descriptions

ATTENTION! Each subwoofi.r has speaker-level and _e-levdinput

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. (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 output of 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 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.

(_) SPEAKER-LEVEL OUTPUT: Audio loop of stereo high-level (SPEAKER-LEVEL) inputs. Use m loop (continue) signal to speaker connections to the left and right 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 main speakers. Referto the owner's manual provided

with your receiver/preamplifier/amplifier(seefigure. 4, fbr hook-up)

0LINE-LEVELOUTPUT (HT-SI5A & LW-15*): Use to loop signal back to the recdver/preamplifiedamplif]erfor distribution to the main speakers. Use the Line-Levd Output if you wish to filter low frequencies out of the signal going to your main speakers. Referto the owner'smanual provided with your receiver/preamplifier/ampl_er. (seefigure 3, j_r hook-up)

®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."

®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.

@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-switchablevoltage 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.
