1IntroductionThank you very much for purchasing the DXS Powered Subwoofer. The DXS is a powered subwoofer usedfor sound reinforcement and temporary installations. This owner’s manual explains how to set up and usethe subwoofer in live venues and temporary PA installations to enhance low-end sound. Be sure to read thismanual before using this subwoofer, in order to make sufficient use of the many functions that this productoffers. Also, be sure to keep this manual after you are finished reading it.Features High power, high sound pressure, superior low-end playback capabilitiesAdopting a bandpass type enclusure for high sound pressure. The DXS features a high-resistance input,low distortion woofer and a 1,020 W power amplifier to achieve superior low-end playback capabilityand high sound pressure. Flexible features• D-XSUB: D-XSUB is a DSP technology that gives users additional dynamic control of the frequencyrange to meet the demands of a variety of applications or musical styles.• Selectable X-OVER (80/100/120 Hz): Selecting the cut-off frequency and LPF/HPF settings offersusers more flexibility to adapt to various applications.• Cardioid mode: The Cardioid mode setting adds additional control of low frequencies for sub-wooferarrays of two or more DXS speakers, effectively reducing the SPL of bass directed towards the stagewhile increasing the bass levels directed towards the audience. ReliabilityA high-performance DSP control protects the speaker and amplifier. The DXS can be used worry-free,even under harsh operating conditions. DurabilityThe DXS’s sturdy plywood cabinet is covered with an extremely durable polyurea finish that providesadded protection from outside elements. Fast and easy setupM20 and Ø35 mm dual pole sockets allow for more flexible set up, while optional casters are also avail-able for improved portability.DXS18DXS15 mkllDXS12 mkllPOWERED SUBWOOFERENZZ20050Owner’s Manual• The DXS18 is mainly used for the explana-tions in this manual.• The illustrations as shown in this manual arefor instructional purposes only.• The company names and product names usedin this manual are the trademarks or registeredtrademarks of their respective companies.Input the output signal from a source, such as a mixer, to the INPUT jack of the DXS, and input the outputsignal from the OUTPUT jack of the DXS to the input jack of a full-range speaker.• X-OVER switch (!2)It is recommended that you match the crossover frequency (the cutoff frequency of the low pass filter)of the DXS and the cutoff frequency of the high pass filter of the full-range speaker. The same fre-quency range output from the DXS and the full-range speaker may cause interference with each otherand degrade the frequency characteristics.• THROUGH/HPF POST switch (o)If the full-range speaker is properly equipped with a high pass filter, you should set this to[THROUGH]. The [THROUGH] setting enables you to control the level independently and minimizesignal delay. If the full-range speaker is not equipped with a high pass filter or the high pass filter in thefull-range speaker cannot be set to the same cutoff frequency as that of the low pass filter of the DXS,set this to [HPF POST] to use the high pass filter in the DXS.This is a pole socket used to mount a full-range speaker atop the DXS. The pole socket is compatible with35 mm or M20 speaker poles, available commercially. When using the pole socket, be sure that the follow-ing conditions are met.Installing optional wheels SPW-1 at the back of the DXS enables you to transport the unit easily. To installthe wheels, use the screws already installed in the DXS unit.Please do not use the speaker once the screws are removed. This causes air leaks to occur in enclosure,resulting in undesirable performance.* If any specific problem should persist, please contact your Yamaha dealer.* The contents of this manual apply to the latest specifications as of the publishing date.To obtain the latest manual, access the Yamaha website then download the manual file.Basic SetupCAUTIONIf multiple powered speakers are connected in daisy-chain fashion, turn each device onin sequence starting from the one nearest to the sound source, and turn them off start-ing from the one farthest from the sound source.Combination of monaural DXS and stereo full-range speakersCombination of stereo DXS and stereo full-range speakersNOTEThe L and R jacks are interchangeable; there is no difference in behavior between them.Full-rangespeaker Combination and setting examplesUsing the high pass filter in theconnected full-range speakerUsing the high pass filter inthe DXSFull-rangespeakerDXSo !2 o !2FrommixerFrom mixerFull-range speaker Full-range speakerMixerTo full-range speakerDXSFull-range speaker Full-range speakerMixerDXS DXSFrom mixerTo full-range speakerInstalling a Speaker PoleSubwoofer Top-mounted speaker Pole lengthDXS18 Weight 28.0 kg or less, height 76 cm or less (DSR115) 120 cm or lessDXS15mkII Weight 19.3 kg or less, height 61 cm or less (DXR12) 100 cm or lessDXS12mkII Weight 14.6 kg or less, height 51 cm or less (DXR10) 82 cm or lessWeight 13.5 kg or less, height 46 cm or less (DXR8) 90 cm or lessInstalling WheelsCAUTION• For details on installing the wheels or special precautions you should take, pleaserefer to the relevant manual for the wheels.• Do not install wheels other than the SPW-1.TroubleshootingSymptom Possible causes Possible solutionPower does not turn on. The power cord is not con-nected properly. Connect the power cord properly.Power suddenly turnedoff.The protection system hasbeen activated, shuttingdown the power supply.Turn off the power, wait until the amplifier cools down,and then turn on again.No sound. The cable is not con-nected properly. Connect the cable to the INPUT jack properly.Sound is interruptedsuddenly.The protection circuit hasbeen activated, muting theoutput.Wait until the amplifier cools down. If the unit doesn’tautomatically reset itself, turn off the power, and thenon again.Sound howls (feed-back).A microphone is directedtoward the speaker.Keep the speaker away from the area where themicrophone picks up the sound.The sound from eachspeaker differs (if multi-ple speakers are used.)The settings for eachspeaker differ.Set each switch of each speaker to the same posi-tion.Sound is distorted.Input volume is excessive. Lower the volume of the input device so that thePEAK indicator lights only occasionally.Output volume is exces-sive.Lower the output level with the LEVEL control so thatthe LIMIT indicator lights only occasionally.General SpecificationsGeneral Specifications DXS18 DXS15mkII DXS12mkIISystem Type Powered subwoofer, band-pass typeFrequency Range (-10 dB) 32 Hz–120 Hz 40 Hz–150 Hz 42 Hz–150 HzMeasured Maximum SPL (Peak)Pink Noise @1m 136 dB SPL 135 dB SPL 134 dB SPLPowerAmplifierPowerRatingDynamic 1,020 WContinuous 800 WPower Consumption(1/8 output power) 100 WComponents LF 18" cone,4" voice coil15" cone,2.5" voice coil12" cone,2.5" voice coilDimensions(W × H × D; including rubber feet) 563 × 683 × 721 mm 480 × 611 × 614 mm 400 × 567 × 570 mmWeight 49.7 kg 36.0 kg 30.0 kgHandles Steel, side × 2Pole Sockets (top surface) Ø35 mm (depth: 80 mm), M20 (threaded depth: 25 mm)ConnectorsInput XLR3-31 × 2Output XLR3-32 × 2 (THROUGH or HPF POST)Power IEC AC inlet × 1 (V-Lock)Input Sensitivity (LEVEL: center) +10 dBuMaximum Input Level +24 dBuM20 screwØ35q Pole socketsAdapts to commercially available speaker poles of 35 mm diameter andM20 screws.

Lights more brightly when the outputlimiter is active. Using FRONT LED DISABLE switch (!9) allows youto defeat the front LED altogether.r Wheel mounting holesOptional SPW-1 wheels can be installed at these locations. For detailson installing the wheels or special precautions you should take, pleaserefer to the relevant manual for the wheels.t AC IN inlet (V-Lock)Connect the AC power cord included with the unit. The AC power cordincludes a locking mechanism with a latch. First connect the DXS to theAC power cord, and then connect the power cord to the AC outlet.When removing the cord, push the latch while pulling the cord out.y Power switchTurns the power to the unit on ( ) or off ( ).If you are using multiple units, turn on the power to each unit one byone. If you turn on the power to multiple units simultaneously, a tempo-rary drop in the power voltage may occur, possibly resulting in abnor-mal operation of the units.Also, rapidly turning the unit on and off in succession can cause it tomalfunction. After turning the unit off, wait for about 5 seconds beforeturning it on again.u INPUT jacksThese are balanced input XLR jacks (line-level), and this device outputsthe mixed signals of L and R.i OUTPUT jacksThese are balanced output XLR jacks for connecting full-range speak-ers or additional DXS units. The output signal can be switched via theTHROUGH/HPF POST switch (o).L/R output from the OUTPUT jacks correspond to L/R input to theINPUT jacks. The mixed signal of L/R is not output.o THROUGH/HPF POST switchSwitches the signals output from the OUTPUT jacks (i).• THROUGH: Outputs unaffected signals from INPUT jacks (u).Select when using HPF of the connected speaker or connecting addi-tional DXS units.• HPF POST: Outputs signal input from INPUT jacks (u) after pass-ing through a HPF. The cutoff frequency of the high pass filter is thefrequency specified with the X-OVER switch (!2). Because the out-put level from the OUTPUT jacks is linked to the LEVEL control(!1), the levels of this unit and the full-range speaker change simulta-neously.!0 PEAK indicatorLights red when the input level reaches 3 dB below clipping. If the indi-cator lights frequently, adjust the volume of the input source or lowerthe LEVEL control (!1) so that the indicator flashes only briefly at thehighest input levels.!1 LEVEL controlAdjusts the output level.!2 X-OVER switchSpecifies the crossover frequency at 120 Hz, 100 Hz, or 80 Hz. The out-put from the unit is processed through a low pass filter to cut the rangeof the selected frequency or higher. When setting THROUGH/HPFPOST switch (o) to [HPF POST], the output signals from the OUT-PUT jacks are processed through a high pass filter to cut the range ofthe selected frequency or lower, and the crossover frequency is linked tothat of the connected speaker.!3 D-XSUB switchSwitches the low-range frequency response characteristics.• NORMAL: A generic setting corresponding to various applications.• BOOST: Boosts the frequency range enhancing and providing punchto the sound.• XTD LF (eXTenDed LF): Extends the bottom of the low frequencyrange.!4 CARDIOID switchConnection of multiple DXS units enables the use of Cardioid mode.For details on Cardioid mode and using the switch, refer to “Setup ofCardioid Mode” on the opposite page.!5 POLARITY switchSwitches the polarity of the unit, normal or inverted. When the polarityis inverted, the INVRT indicator lights.In most cases, this should be set to normal; however, the inverted settingmay improve low-range response, depending on the type and location ofthe speaker system. Select a setting that produces the best low-endsound.!6 LIMIT indicatorLights when the output limiter is active. The output limiter operates inorder to protect the speaker and amplifier, attenuating the output signalto the amplifier. If the indicator lights frequently, adjust the volume ofthe input source or lower the LEVEL control (!1) so that the indicatoronly occasionally lights at the highest input levels.!7 PROTECTION indicatorLights when the protection system is active. The protection systemoperates and the speaker output is muted in the following situations.• If amplifier overheating is detected.• If overcurrent is detected.• Immediately after turning the power on. (The protection system isactivated to prevent noise and the indicator lights for about two sec-onds. The indicator turns off when the power supply has started nor-mally.)!8 POWER indicatorLights when the power is on.!9 FRONT LED DISABLE switchTurns the FRONT LED at the front of the unit on or off. The LED lightswhen this switch is set to off. Turn this switch on to disable the LED.Controls and functionst yqruo!0!1!2 !3 !4!5!6!7!8!9iweCAUTIONDo not stack more than two DXS units.CAUTIONTurn off the power before you connect or discon-nect the power cord.CAUTIONA slight electrical current will flow even when thepower switch is turned off.
