Your Acoustic Research Subwoofer delivers powerful, deep bass soundoutput for a natural, life-like sonic experience. Please follow the direc-tions in this manual to achieve the best performance from your system.The hook-up and operation of the Subwoofer is the same for a HomeTheater surround sound system or a stereo music system. TheSubwoofer has its own built-in amplifier, so it works with any soundsystem. The Subwoofer’s own crossover network sends bass-onlysignals to the Subwoofer’s built-in amplifier. This lets the Subwoofer addextra bass to the output from your other speakers.For simplicity, we call your Home Theater system’s or music system’smain speakers the Front speakers. We call your AV receiver, stereoreceiver, or integrated amplifier the Receiver.PLACEMENTYour Acoustic Research Subwoofer must sit on the floor, in a corner towork properly. The floor and corner are actually a part of the Subwoofer’sdesign.Place your Subwoofer in the corner nearest your system’s electroniccomponents to keep wire or cable runs short.SUBWOOFER CONTROLS & CONNECTIONSPOWER CORD Plug the power cord into anAC wall outlet or other AC outlet capable ofsupplying at least 400 Watts.POWER SWITCH Turns the AC supply com-pletely OFF or sets the Subwoofer to AUTO ONoperation. In AUTO ON, the Subwoofer is instandby mode until it detects an audio signalinput, then the Subwoofer turns on automati-cally. A few minutes after audio input signalscease, the Subwoofer automatically returns tostandby mode.POWER INDICATOR LED This LED is unlitwhen the AC power switch is OFF. It glows redwhen the Subwoofer is in standby mode adgreen when the Subwoofer is on.FUSE 250V 3A This fuse protects againstinternal and external faults. If the POWERswitch is ON and the power indicator LED isunlit, unplug the power cord from the ACoutlet and check the fuse by unscrewing thecenter piece from the holder. IMPORTANT Ifthe fuse is blown, replace it only with a fuse ofthe same type and current rating.L, R SPEAKER-IN TERMINALS - See Connection Option 1These terminals are for making connections using speaker wire. If youuse this option, do not use Option 2.LINE IN - See Connection Option 2This jack is for connection using an audio cable. If you use this option,do not use Option 1.LOW PASS FREQUENCY CONTROL Adjusts the upper frequency limitfor audio signals going to the Subwoofer amplifier. This control helpsyou adjust the system tonal balance.LEVEL CONTROL Balances the loudness of the Subwoofer relative tothe Front speakers and compensates for room effects on the Subwoofer’soutput.PHASE SWITCH The Phase Switch controls the phase of theSubwoofer’s output relative to the front speakers. Listen carefully to thesound quality while playing a CD with low bass. Select the position ofthe switch that produces the fullest deep bass without boominess. Youmay need to readjust the Level and Low Pass Frequency controls aftersetting the Phase Switch.CONNECTING YOU SUBWOOFERIMPORTANT When you make connections. make sure that the powerswitches of all components, including the Subwoofer, are OFF.AUDIO CABLES If you are connecting the Subwoofer into a systemmade up of separate components (preamp & power amps), you will needaudio cables long enough to reach the Subwoofer from the preamplifierand the power amplifier.SPEAKER WIRE Typical speaker wire has a pair of separate conductorswith insulating jackets that are molded together. We recommend thatyou use 16-gauge speaker wire for hooking your Receiver to your Frontspeakers. To make connections to the Subwoofer in parallel with theFront speakers easier, the speaker wire connecting the Receiver to theSubwoofer can be smaller (higher gauge number), since the Subwooferdoes not draw large amounts of power through these wires.POLARITY All speakers in a system must be connected with the samepolarity. Speaker wire is marked for polarity so that you can identifywhich wire in the pair is which. Polarity is shown by a color strip on theinsulation, by ridged molded into the insulation, or by the colors of thewires - one copper and one silver.Strip the insulation from speaker wire ends to reveal the bare conductorsbefore connecting to Receiver, Subwoofer or Speaker terminals.IMPORTANT Always connect the red + terminal on the Receiver to thered + terminal on the Subwoofer, and the black - terminal on the Receiverto the black - terminal on the Subwoofer. The same is true for hookingthe Receiver outputs to the Front speakers: red + to red +, and black- toblack-.IMPORTANT USE OPTION 1 OR OPTION 2, NOT BOTH.OPTION 1 – CONNECTION WITH SPEAKER WIREConnect speaker wires from the Receiver’s front left and right speaker outputs tothe subwoofer’s left and right Speaker In terminals. Connect speaker wires fromthe subwoofer’s left and right Speaker Out terminals to the left and right frontspeakers being used in the system.OPTION 2 – CONNECTION WITH AUDIO CABLEConnect an audio cable from the Subwoofer Out or LFE Out on the back of yourReceiver to the Line In jack on the back of the subwoofer.LEVELLOW PASSFREQUENCY• MAXMIN •• 100HZPHASE0º180º50HZ •L ROUTINLINEPOWERAUTO ON OFFFUSE250V T3A120V60HZ 300W180º++RLSERIAL NO.:MODEL NO.: ARS115PSBCAUTIONRISK OF ELECTRIC SHOCKDO NOT OPENWARNING: SHOCK HAZARD-DO NOT OPENAVIS: RISQUE DE CHOC ELECTRIQUE-NEPAS OUVRIRCAUTION:TO REDUCE THE RISK OF FIRE,REPLACE WITH ONLY THE SAMETYPE AND RATING OF FUSE.ATTENTION:UTILISER UN FUSIBLE DERECHANGE DE MEME TYPE.!INOUT--SPEAKERLEVELSUBWOOFER ADJUSTMENT & USESubwoofer initial control settings• Set the LOW PASS FREQUENCY Control to its center position.• Set the LEVEL Control fully counterclockwise to MIN. You’ll resetthis control after you make other adjustments.Adjusting the Subwoofer controls• Play a program on your system. For the following adjustments, usethe Dolby ProLogic Normal surround mode and select a movie thathas a Dolby Surround soundtrack with a lot of music, or play a musicCD. Adjust the Receiver’s volume control for a comfortable soundlevel from the system speakers.• Increase the Subwoofer’s LEVEL Control setting clockwise, so thatyou hear the deep bass. Adjust the control for a natural, musicalbalance that has plenty of deep bass sound when it is actuallypresent in the music.• Listen carefully to bass voices and, if needed, adjust the LOW PASSFREQUENCY Control so that they sound natural. Setting thefrequency too high will make deep voices sound excessively“chesty” or resonant and will give the upper bass in music a “one-note” quality. Setting the frequency too low will make deep voicessound “thin” and will give music a lack of “warmth”.• Make fine adjustments until the program has satisfying and naturalsound quality on both bass voices and music.TROUBLESHOOTINGSubwoofer POWER Indicator LED does not light• Check that the Subwoofer’s POWER Switch is in the AUTO ON position.• If the POWER Switch is in the AUTO ON position, check the AC outlet the Subwoofer is plugged into to be sure that it is live. You canuse a tester or plug-in a lamp to check it.• If the AC outlet is live, either the power cord or Subwoofer has aproblem. Unplug the power cord from the AC outlet and check thefuse by unscrewing the center piece from the holder. If it is blown,replace the fuse only with a fuse of the same type and rating. If thisdoesn’t help, take the Subwoofer to your dealer for service – THEREARE NO USER SERVICEABLE PARTS INSIDE.No sound from the Front speakers.• Be sure the Receiver and Subwoofer POWER Switches are in the Onpositions.• Check the Receiver’s Volume Control Setting - if it is all the waydown, there won’t be any sound.• Check that the Receiver’s Input Selector is set to an active source ofaudio signals and that a Tape Monitor Loop is not engaged.• Be sure that the Receiver’s Speaker Selector switch is turned on tothe terminals [A or B, 1or 2] that you have your Front speakersconnected to. If the Receiver has a headphone jack, you can useheadphones to check the Receiver for output.• Check the wires and connections from the Receiver’s Front SpeakerOutput terminals to the Subwoofer’s SPEAKER-IN terminals.• Try removing the Subwoofer from the system, leaving your Frontspeakers connected to the Receiver. If there still is no sound, takethe Receiver to your dealer for service.No sound from the Subwoofer• First, be sure there is sound from the Front speakers and that theReceiver is working correctly as outlined above.• Check the Subwoofer’s LEVEL Control. If it is all the way counterclockwise, there may be no sound.• The Subwoofer only reproduces deep bass sound. If the programhas no deep bass, the Subwoofer will not make any sound. Play aprogram with plenty of bass, such as jazz or rock music, or an actionmovie.• If everything else checks OK, take the Subwoofer to your dealer forservice - THERE ARE NO USER SERVICEABLE PARTS INSIDE.SPECIFICATIONSDriver Complement and Enclosure15” long throw woofer in a down-firing configuration.Slot-loaded, Port Tuned enclosure design.Frequency Response30 Hz to 100 HzAmplificationPower output: 200 Watts RMS into 8 Ohms with protective limiter enabled.Total Harmonic Distortion1% @ 200 Watts outputSignal-to-Noise Ratio>90 dBCrossover frequency (-3 dB)50 Hz @ MIN 200 Hz @ MAXSpecial Features:2 pairs 5-way gold binding posts for high level out2 pairs 5-way gold binding posts for high level in1 pair RCA inputs for low level input1 pair RCA inputs for low level outputFinish: Black ash laminateDimensions: 16 (40.64 cm) x 19" (48.26 cm) x 19" (48.26 cm)Weight: 66 lbs (29.94 kgs)LIMITED WARRANTYThis warranty remains in effect for five years from the date of purchase forspeaker products and one year for electronic products.This warranty protects the original owner providing that the product hasbeen purchased from an authorized Acoustic Research dealer in the UnitedStates.
