Use the high level outputjacks to connectthe subwooferto a pair of left and right main speakers.(See wiring diagramsJ When connectingthe subwooferto your system,it is recommended that you usehigh quality speakercable and try to maintaincableruns of the samelength for the left andright channels.Shouldyou perchanceexperienceany level of groundhum or noise,try plugging,the subwooferinto the samecircuit asyour"amplifier.Also, consultthe "Troubleshooting"sectionof this manual.To preventaccidentaldamageto your subwooferfrom overdriving the system,the subwoofer featuresan internal overloadprotectioncircuit.

Your Definitive Technologysubwooferhasbeendesignedto operateat frequenciesgenerallybelow 150Hz. Becauselow-frequency information in this rangeessentiallyis non-directional,your subwoofer canbe locatedanywherein your listening room that is most convenient.Also, the continuouslyvariable low filter operatesat a very fast roll-off, ensuringgreatperformancewhereveryou place your subwoofer.Thereare,however,somegeneralrules that you shouldbearin mind when locating your subwoofer: 1. For maximum output the subwoofershouldbe placedin a comer or againstthe wall, leaving roughly 2"-4" clearancebetweenthe subwoofer and the wall(s). 2. Comer placementwill increasethe subwoofer'sefficiency,which in turn will increaseyour system'smaximum output and improve the dynamiccapability of the subwoofer. 3. While one Definitive Technologysubwooferwill alwayssou.nd great,the useof two subwooferswill definitely enhanceyour system's performanceby providing a smootherand more consistent responsepattern.Here,it is recommendedthat you locate the subwooferson the sameside of the room as the main speakerof the same channel. 4. Always that frequencyresponseand output lev.((lare greatly influencedby the subwoofer'splacement.A movementof evenafoot or two can dramaticallychangeyour system'sresponse characteristics.You shouldexperimentwith placementin your particular listening room in order to achievethe highestperformancefrom your subwoofer. 5. Your subwoofercontainsa powerful amplifier inside its cabinetry. When placing the subwooferinto a built-in cabinet,pleasebe sureit receivesa clear flow of cooling air. If your subwooferis to be located in a closed-backcabinet,be sureto put someventilation holesin the cabinetback behind the subwoofer'sback . 6. Sincethe subwooferhassomeoutput from therear, if you put the subwooferin a cabinet,leave2"-4" aroundthe outsideof the subwoofer for the soundfrom the rear to get out. 7. When using the ProSub 80 with Definitive ProMonitors, consult the ProMonitor instruction manual for other placement tips.

Low Level Connections Oneway to hook up your Definitive TechnologyProSub80 subwoofer is via the low level input connectorswhich are RCA-type jacks designedto acceptstandardaudio interconnectcables.For preampsand decoders,run an interconnectfrom the left and right outputs of the preampor decoderto the left and right low level input5on the subwoofer.If you have two setsof outputs,you can useone set of these;if not, you can put a Y-connectorinto eachoutput (left and right) and run half of eachY back into a (left and right) main input on the preampdecoder,receiveror power amp and the other half into the (left and right) low level input on the subwoofer. Additionally, I!lany new model receivers,preampsand decoders featurea mono (line level) output intendedto be usedwith subwoofers.You can feed the mono or LFE subwooferoutput of your receiveror decoderto the LFE low level input on the subwooferand achievefull performance.Often theseoutputshavetheir own low IPRE-AMPLIFIER -- --- ---

We recommendthis hook-up (wiring the main speakersthroughthe crossoverin the subwoofer) whenusingProMonitors.For moreoverallbassoutputwhenusingfull rangemain spe~ers, run the main speakersfull rangeby hookingthem up directly to the amp.In many systems,if your speakersaretrue full rangesystems,you may find that you get a more satisfyingsoundby running the speakersfull-range and crossingyour subwooferin fairly low (40-70Hz). On the otherhand,if you find that you are overdriving your main speakers,you will clearly be able to play your systemlouder by using the built-in high crossoverfor your main speakers. The Advantages of Multiple Subwoofers Definitive's ProSub 80 subwoofersare engineeredto be used singly or in stereopairs. With a single subwoofer, both left and right signals are sentto the subwoofer wherein they are combined via the electronic crossoverinto one composite signal. With stereosubwoofers, the left and right low frequency signals are reproducedby their own individual subwoofers. The use of one subwoofer achievesoutstanding performance; however, the addition of a secondsubwoofer (one for the left and one for the right channel) clearly offers the highest level of performance achievable for both movies and music. The use of stereosubwoofers smoothes out the peaksand dips which result from the eigenmodesin your room. Two subwoofers couple much better to the air in your room (four times",'. better) and of courseoffer double the power. In addition, some1state-ofthe-art home theater installations have begun to use a separatesubwoofer hooked up to the rear (surround) channelsand we recommenAthis for the absoluteultimate in performance.In addition, some state-of-the-art Dolby Digital* home theater installations"have begun to use a separate subwoofer hooked up to the rear (surround) channels and we recommend this for the absolute ultimate in performance.

Dual Subwoofer Connections When hooking up a stereopair of subwoofers,wiring is quite similar to traditional high level connections.Here, insteadof running both speaker cablesfrom your receiveror amplifier to the left and right high level terminals on the subwoofer,you will run the left channelto the left channelsubwoofer and the right channelto the right channelsubwoofer.Again, take careto makered to red ("+") and black to black ("-") terminal connections. Don't worry that on your left subwoofer the right channel terminals will be empty and that on the right channel subwoofer the left channel terminals will be empty-both channels are combined at the subwoofer's input stage.There is a possibility that with this type of wiring you may need to increaseyour gain a little bit for proper balance.

Gain Control On the back of your subwooferis a gain (volume) control. This control is usedto raise or lower the output level of your subwooferin relationto the other speakersin your system. Low Filter Your subwoofer'sback featuresa continuouslyvariablelow filter. This filter is continuouslyvariablebetween40 and 150Hz. This low filter control is usedto obtain the optimum transition between and your main speakers. shouJd besetbythe earsubwoofer for bestperformance in your room.This Setitcontrol to where it . soundsbestto you. If you are running your main speakersfull range, we would generallyrecommendsettingthe low filter fairly 10w (40-70 Hz). When using the ProSub80 with Definitive ProMonitors, pleaseconsultthe instruction manual section"Using the ProSub 80 with Definitive ProMonitors."

Your subwoofercontainsa built-in, active poweredsubwoofersection aswell as an electroniccrossoverand so eachsubwoofermust be pluggedinto an electrical socketof the appropriatevoltage (as indicatedon the back of your unit) using the plug on the end of the black cord attachedto the electronicsmoduleon the back of the loudspeaker. The subwooferhas a specialcircuit which automaticallyturns the poweredsubwoofersectionon when a signal is fed to the loudspeaker and doesnot require an on-off switch. TheTedLED on the back will light up when a signal is sensedand the amplifier turns on. It will automaticallyturn off a little while after the signal is discontinued.

If you experience any difficulties with your subwoofer, try the suggestions described below. If you are still having problems, please consult your Definitive Technology Authorized Dealer for assistance. 1. Make sure all your system interconnects and power cords are solidly in their place. 2. Should you experience any level of ground hum or noise, try plugging the subwoofer into the same circuit as your amplifier. Please note that some cable TV hookups induce hum into the whole system and require a special isolation device. Please consult your dealer.

.

3. The system is provided with sophisticated internal protection circuitry. If for some reason the protection circuitry is tripped, please turn down your system's volume and wait five minutes before trying

the system again. If the amplifier should overheat, the system will turn itself off until the amplifier cools and resets. 4. Check to be sure that your power cord has not been damaged. 5. Check that no foreign objects or liquid has entered the cabinet. 6. If you cannot get your subwoofer to turn on or if no sound comes out and you're sure the system is set up properly, pleasebring the subwoofer to your Definitive Technology Authorized Dealer for assistance.
