INTRODUCTION AND FEATURES

INTRODUCTIONCongratulations on your purchase ofthis Performance™ Series JBL BassQ™

processor! You have purchased a product that embodies the best of whatJBL® engineers have learned about the emotional power of audio reproductionin more than fifty years of preeminencein the field. This processor has beendesigned and crafted to provide the userwith a high level of sonic performance.Special attention has been paid to minimizing the number of componentsin the audio signal path, resulting inextremely low distortion, excellenttransient response and wide dynamicrange. JBL products set new bench-marks in audio technology and, when used as part of a complete JBLPerformance Series system, will bringthe ambience and acoustics of some ofthe world’s greatest concert halls andtheaters into your home.

To obtain the best performance from thisprocessor, please be sure to completelyread this user’s manual and use the JBLBassQ processor only in accordancewith its instructions.

FEATURESThe JBL BassQ processor features the following:

Minimum Phase DistortionThe algorithms used to calculate andcorrect the room modes are designedto give the best results with the leastamount of phase-induced distortion.This is unique to the JBL BassQprocessor and is not available fromany other product.

Mono or Stereo InputsSupporting both LFE and stereo sub-woofer inputs allows for a greaterrange of applications and allows theJBL BassQ unit to be used with a varietyof different processors. Although thesystem has been designed to workwith the rest of the Performance Seriessystem, including AV1 and AVA7, the unit can be used in almost any system and can improve the in-roomresponse of almost any installation.

Multiple Subwoofer OutputsUp to four subwoofers can be optimized.Multiple subs allow better seat-to-seatresponse and can greatly improve the listening experience over a singlesubwoofer. The JBL BassQ unit allowsoptimizing multiple subs to achieve the most accurate in-room responsepossible.

Auto Turn-On and Power-Sequencing Due to the high current demands ofpower amplifiers at the instant of turn-on, the JBL BassQ processor isequipped with a power-sequencing circuit that turns on each amplifier in a delayed sequence, avoiding the largeinstantaneous current demand (andpossible circuit breaker tripping) thatcould otherwise occur, should more thanone amplifier turn on at the same instant.

Multiple Microphone InputsMultiple microphones allow for theoptimization of multiple seats. Thisresults in a larger listening area thatbenefits from a more accurate roomoptimization.

Two Listening CurvesTwo different playback curves have beenimplemented to better match the type ofplayback material. Cinema mode closelyfollows the standard for playback curvesused in commercial cinemas and scoringstages. This will allow the system toclosely match the experience of thedirectors and producers of popular filmsand TV shows. Music mode is a gentlerplayback curve that better mimics thefrequency response in most music production studios.

11. Main Power Switch Place this switch in the On position atall times during normal use.

12. Power Trigger Input JackWhen using the JBL BassQ processorin a JBL Performance Series systemwith the AV1 digital surround processor,you will need to use the trigger cableset included with the AV1. Connect theDIN end of the cable to the TriggerOutput DIN jack on the rear panel of theAV1, and connect the 1/8" (3.5mm) plugto the Trigger Input Jack � on the rearpanel of the JBL BassQ unit.

If the JBL BassQ unit is used withanother component (such as the AV2)that uses a trigger for automatic turn-on and turn-off, make sure the othercomponent’s output is between 3 and24 volts DC. Connect the trigger outputjack on the other component to the1/8" (3.5mm) Trigger Input Jack � onthe JBL BassQ unit using the cableincluded with the JBL BassQ unit.Whenever a power-on trigger is usedto operate the JBL BassQ processor,make sure that the JBL BassQ MainPower Switch � is in the On position.If the Trigger source (AV1 or anothersource unit featuring power-on trigger)is on, the JBL BassQ LED StandbyIndicator ™ will glow blue. If theTrigger source is off or in Standby, the JBL BassQ unit will also go intoStandby and its LED Standby Indicator™ will turn red. The remote controlwill overide the trigger input.

13. Power Trigger OutputsIf you wish to have other componentsin your system turn on via trigger,make sure they are compatible withthe 1/8" (3.5mm) 12-volt DC TriggerOutput Jack � on the JBL BassQunit. If they are, you may connect theTrigger Output Jack � to the firstcomponent’s trigger input using one ofthe cables included with the JBLPerformance Series AVA7, and

then connect all components in daisy-chain fashion.

There are five trigger outputs on therear panel of the JBL BassQ unit.

• Pass-through sends the 12-volt triggersignal out in parallel to the input. Use this to trigger the AVA7 amplifier,or the first amplifier you are using in the system.

• 2S sends the 12-volt signal 2 secondsafter the input is received.

• 4S sends the 12-volt signal 4 secondsafter the input signal is received.

• 6S sends the 12-volt signal 6 secondsafter the input signal is received.

• 8S sends the 12-volt signal 8 secondsafter the input signal is received.

14. Movie Trigger InputUsing a 12-volt trigger from the Movie/Music switching can be automated. If you are using the AV1 processor,use the DIN-to-mini trigger cableincluded with the AV1, as this switchingis already programmed into the triggeroutputs of the AV1. If you are usingthe AV2 or another component thathas a programmable trigger, use the2.5mm to 3.5mm cable included withthe JBL BassQ unit. The remote controlwill overide the trigger input.

15. Subwoofer InputsThere are two subwoofer inputs. If using an AV1 processor or otherprocessor that has a single subwooferor LFE output, connect the subwooferoutput to the Left input and set the inputmode to Mono on the front panel of theJBL BassQ unit. Do not connect theinput to the Right input jack, as no sig-nal will be processed. If you are using a preamp/processor such as the AV2, or an AVR that has stereo subwooferoutputs, connect the left and rightinputs and set the mode to Stereo onthe front panel of the JBL BassQ unit.

16. Subwoofer OutputsThere are four subwoofer outputs.These correspond to two subwoofersper side. For best performance, it is recommended that you use atleast two subwoofers placed in thefront left and front right corners of theroom. These would use the L1 (Left 1)and R1 (Right 1) outputs. If four sub-woofers are used, the additional sub-woofers would be connected to the L2 (Left 2) and R2 (Right 2) outputs. Ifstereo input is used, the left and rightoutputs will pass through the respectiveinput signal as a stereo subwoofer.

17. AC Inlet Your JBL BassQ processor is shippedwith an IEC-type, removable powercord that mates with the AC inlet on therear panel. To ensure proper operation,use the supplied power cords. The JBLBassQ processor is a multivoltage unitand can operate from 110 to 240 volts,50Hz to 60Hz. Two cords are supplied.One is a 120-volt cord for use in NorthAmerica, and the second is a genericcord, which requires that the correctmating plug be attached for yourcountry’s specific type.

18. RS-232 PortThis port is for factory use only. Nouser features are available at this time.

REMOTE CONTROL BATTERYINSTALLATION

The remote control requires one CR2032battery. The battery should be replaced asneeded. When battery power is low, theremote control enters a low-voltage con-dition, preventing it from operating the JBL BassQ unit. When this occurs, replacethe batteries. Normal operation willresume when new batteries are installed.

To replace the remote control batteries:

1. Locate the battery compartment on theback of the remote control. Pull downon the battery tray to slide out the oldbattery. The tray is held in place by apressure-fit lock and requires a smallamount of force to remove.

2. Remove the old battery.

3. Observing the proper polarity, insertone CR2032 battery.

4. Slide the battery tray back into theremote until the tray locks into place.

CAUTION: DANGER OF EXPLOSION IFBATTERY IS INCORRECTLY REPLACED.REPLACE ONLY WITH THE SAME (CR2032)OR EQUIVALENT TYPE.

WARNING:

• DO NOT EXPOSE BATTERIES TO EXCESSIVE HEAT SUCH AS DIRECTSUNLIGHT, FIRE OR THE LIKE.

• DISPOSE OF DEAD BATTERIES IN ACCORDANCE WITH LOCAL REGULATIONS.

PHYSICAL INSTALLATION

Installation of the JBL BassQunit is a straightforward process.

IMPORTANT: The JBL BassQ unit must be installed following the directions below. Always put amplifiers on the bottom of a stack. Heavy equipment should not be supported solely by the front-mounting locations.

1. The JBL BassQ unit has beendesigned to be mounted in EIA-standard racks, or stacked freestanding. If the unit is beingmounted in a rack, it is recommendedthat its feet be removed prior toinstallation. If it will be stacked withother components, use the feet thatcame attached to the unit. This willensure that there is sufficient spaceunderneath so that heat can be dissi-pated effectively. Two rack ears areincluded with the JBL BassQ unit. To install these rack ears, remove thetwo machine screws on each of thetwo side panels (see drawing), holdeach rack ear in place, and attach it to the unit using the same two screws.Make sure that these screws aresecurely tightened.

2. Make sure that the unit is located in a well-ventilated, cool area. If it is installed inside a cabinet that isenclosed on all sides, the front of thecabinet must remain open to allowsufficient flow-through ventilation to avoid overheating.

3. With the help of another person toguide the unit into the rack, gentlyslide the JBL BassQ unit into place.Align the rack mounting holes to therack ears of the equipment rack.

4. Starting with the bottom two screwholes and using two of the rackscrews and plastic washers (if sup-plied with your rack), secure the JBLBassQ unit into the rack. It may benecessary to have a helper hold upthe rear of the unit until you havestarted the threads of the screws.

Once the bottom mounting screwsare installed, move to the top mount-ing screws. Once done, check and tighten all four screws. Always use all four screws when mountingany equipment.

Once you have connected the sub-woofer input into the JBL BassQ unitand connected the outputs from the unitto all subwoofers in the system, you willneed to run the BassQ test to finalizethe room calibration and correction.

Before You BeginIt is very important that all subwoofersare on and installed before you run theBassQ process. If you move a sub-woofer or add a sub to the system, youwill need to rerun the test. Set all initialsettings on all attached subwoofers orsubwoofer amplifiers to nominal or 0dBinput level (phase set to 0°) and bypassall internal crossovers.

If Your System Includes an AV2Before beginning any calibration, selectBASSQ ->Yes from the AV2 Setup menu.This will optimize the delay settings andAV2 Autocal for use with the JBL BassQprocessor. It will be necessary to manu-ally set the subwoofer output level fromthe AV2 processor. See the AV2 manualfor details.

Step One: Microphone SetupBegin the calibration process by settingup the microphone array to test the listening area. The JBL BassQ unitincludes four microphones, four micro-phone bases and eight microphonestands. Begin by screwing togethertwo stands to make four tall stands.Press the poles firmly into the base.The hole in the base will securely holdthe stand, but you should make surethat the stand is in the base before pro-ceeding. Next, screw one microphoneeach into the top of the stand. Each

microphone comes with an attachedcable with a 1/4" jack on the end. Plugeach microphone into the front of theJBL BassQ unit, using the diagrambelow as a reference for placement. It is important that the microphonescover the listening area.

Step Two: Turn On All ElectronicsMake sure that all electronics are on,including all subwoofers or subwooferamplifiers. Turn down or mute the vol-ume on the preamp.

NOTE: Many self-powered subwoofers,such as the PS1400 and HTPS-400, haveauto turn-on based on signal sensing.Either turn them to On or make surethat they are on and remain on for thistest. If the subwoofers are not alreadyon, the first part of the test tone will beclipped and BassQ will not properlycalibrate the room.

Step Three: Begin the BassQ ProcessThe first time you power up the JBLBassQ unit, the blue light will be off andthe unit will be in Bypass mode. Pressthe BassQ button. The BassQ light willbegin to blink, indicating that it hasstarted the process. You will hear a testtone from each subwoofer, one at atime. When the process is finished, the BassQ light will be solid and the subwoofer lights will flash briefly to indicate which outputs have subwoofersattached and are calibrated. You canconfirm which outputs are calibrated byplacing the unit into Standby mode andthen on again. The lights will go on brieflyto indicate which outputs are active.

NOTE: When using an AV2, it is importantto run the Autocal only after using theBassQ process and setting the BassQsetting to Yes in the AV2 setup menu.See the AV2 manual for details.

Step Four: Level Calibration of Main Speakers

Level adjustments are best done usingan SPL meter that is set to C-weightingand Slow response. Set the level controlon your subwoofer to 0dB or a nominalreference level. Turn on the internalnoise test from the AV1 (or otherprocessor) and, using the level controlin your preamp or processor, set allspeaker levels to a 75dB referencelevel. If using the AV2 Autocal, the levelswill automatically be set. Be sure to setthe AV2 to Yes for BassQ in the AV2setup menu.

Step Five: Distance Calibration Due to the different distances betweenthe listening position for the subwoofer,the front channel speakers and the sur-round speakers, the amount of time ittakes for sound to reach your ears fromfront speakers versus surround speakersdiffers. You may compensate for this difference through the use of the delaysettings to adjust the timing for thespeaker placement and acoustic conditions in your listening room orhome theater. Begin by measuring the distance between your listeningposition and each of the speakers inyour system. Write these down, as youmay need to remember them in thefuture. If you have more than one subwoofer, it is best to place them an equal distance from the listeningposition. If this is not possible, use thedistance from the closest subwooferfor the speaker distance settings. Ifusing the AV2 Autocal, the distanceswill automatically be set. Be sure to set the AV2 to Yes for BassQ in the AV2setup menu.

Step Six: Enjoy the Music You can now disconnect all the micro-phones and pack up the stands. Keepthese, in case you need to rerun thetest. Unmute the preamp and enjoy.
