You have purchased a product that embodies the best of what JBL® engineers have learned about the emotional power of audio reproduction in more than fifty years of preeminence in the field. This processor has been designed and crafted to provide the user with a high level of sonic performance. Special attention has been paid to minimizing the number of components in the audio signal path, resulting in extremely low distortion, excellent transient response and wide dynamic range. JBL products set new benchmarks in audio technology and, when used as part of a complete JBL Performance Series system, will bring the ambience and acoustics of some of the world's greatest concert halls and theaters into your home. To obtain the best performance from this processor, please be sure to completely read this user's manual and use the JBL BassQ processor only in accordance with its instructions. Multiple Subwoofer Outputs Up to four subwoofers can be optimized. Multiple subs allow better seat-to-seat response and can greatly improve the listening experience over a single subwoofer. The JBL BassQ unit allows optimizing multiple subs to achieve the most accurate in-room response possible. Auto Turn-On and Power-Sequencing Due to the high current demands of power amplifiers at the instant of turn-on, the JBL BassQ processor is equipped with a power-sequencing circuit that turns on each amplifier in a delayed sequence, avoiding the large instantaneous current demand (and possible circuit breaker tripping) that could otherwise occur, should more than one amplifier turn on at the same instant. Multiple Microphone Inputs Multiple microphones allow for the optimization of multiple seats. This results in a larger listening area that benefits from a more accurate room optimization. Two Listening Curves Two different playback curves have been implemented to better match the type of playback material. Cinema mode closely follows the standard for playback curves used in commercial cinemas and scoring stages. This will allow the system to closely match the experience of the directors and producers of popular films and TV shows. Music mode is a gentler playback curve that better mimics the frequency response in most music production studios. FEATURES The JBL BassQ processor features the following: Minimum Phase Distortion The algorithms used to calculate and correct the room modes are designed to give the best results with the least amount of phase-induced distortion. This is unique to the JBL BassQ processor and is not available from any other product. Mono or Stereo Inputs Supporting both LFE and stereo subwoofer inputs allows for a greater range of applications and allows the JBL BassQ unit to be used with a variety of different processors. Although the system has been designed to work with the rest of the Performance Series system, including AV1 and AVA7, the unit can be used in almost any system and can improve the in-room response of almost any installation.

Power Switch Pushing this button is all that is required to turn on the unit if it is not part of a JBL Performance Series system and the Main Power Switch A is in the On position. 2. Standby Indicator This indicator on the front-panel Power Switch ¡ will glow red when the JBL BassQ unit is in the Standby mode, whether it is operating as part of a JBL Performance Series system or not. When the unit is in the On mode, this light will turn blue. 3. Input Overload The light will glow orange when an overload to the input occurs during testing. If this lights during testing, you should lower the level control on the subwoofer. It may be necessary to lower it significantly for the test, but the level control should be raised back to normal levels after the test is completed. 4. BassQ Pressing this button runs the subwoofer test and calibrates the system. The indicator light will be off if the calibration has not been performed. The indicator light flashes blue during the process to indicate that the system is being calibrated. The indicator light will be solid blue once the calibration is complete. 5. Movie Pressing this button toggles between the Movie EQ mode and Music EQ mode. The indicator light will glow blue when Movie mode is selected, and remain off when the JBL BassQ unit is in Music mode. 6. Stereo Pressing this button toggles between Stereo and Mono inputs on the rear panel. The indicator light will be lit when the input is set to Stereo input and be off when set to Mono input. This needs to match the input configuration on the rear panel and should not be changed once it is set. Use the Mono setting for the AV1 or other processor that uses an LFE output. Use Stereo setting for processors that include stereo subwoofer outputs. 7. Bypass Pressing this button bypasses all JBL BassQ processing. The indicator light will glow blue when Bypass is engaged. 8. Subwoofer Indicators After the JBL BassQ system has completed the calibration, the indicator light will flash to confirm which subwoofers are active and have been calibrated. The lights will flash again when the system is turned on or taken out of Standby, but will not remain lit during normal operation. 9. Microphone Inputs Connect the four included microphones into these inputs. The microphones should be placed in the appropriate seating locations. Please refer to the diagram on page 10. 10. IR Sensor The IR sensor allows use of the included remote control to operate the unit from across the room. The IR sensor must not be blocked, in order for it to operate properly. 5 18 15 12 16 14 13 11 17 11. Main Power Switch Place this switch in the On position at all times during normal use. 12. Power Trigger Input Jack When using the JBL BassQ processor in a JBL Performance Series system with the AV1 digital surround processor, you will need to use the trigger cable set included with the AV1. Connect the DIN end of the cable to the Trigger Output DIN jack on the rear panel of the AV1, and connect the 1/8" (3.5mm) plug to the Trigger Input Jack B on the rear panel of the JBL BassQ unit. If the JBL BassQ unit is used with another component (such as the AV2) that uses a trigger for automatic turnon and turn-off, make sure the other component's output is between 3 and 24 volts DC. Connect the trigger output jack on the other component to the 1/8" (3.5mm) Trigger Input Jack B on the JBL BassQ unit using the cable included with the JBL BassQ unit. Whenever a power-on trigger is used to operate the JBL BassQ processor, make sure that the JBL BassQ Main Power Switch A is in the On position. If the Trigger source (AV1 or another source unit featuring power-on trigger) is on, the JBL BassQ LED Standby Indicator TM will glow blue. If the Trigger source is off or in Standby, the JBL BassQ unit will also go into Standby and its LED Standby Indicator TM will turn red. The remote control will overide the trigger input. 13. Power Trigger Outputs If you wish to have other components in your system turn on via trigger, make sure they are compatible with the 1/8" (3.5mm) 12-volt DC Trigger Output Jack C on the JBL BassQ unit. If they are, you may connect the Trigger Output Jack C to the first component's trigger input using one of the cables included with the JBL Performance Series AVA7, and then connect all components in daisychain fashion. There are five trigger outputs on the rear panel of the JBL BassQ unit. · Pass-through sends the 12-volt trigger signal 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 seconds after the input is received. · 4S sends the 12-volt signal 4 seconds after the input signal is received. · 6S sends the 12-volt signal 6 seconds after the input signal is received. · 8S sends the 12-volt signal 8 seconds after the input signal is received. 14. Movie Trigger Input Using 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 cable included with the AV1, as this switching is already programmed into the trigger outputs of the AV1. If you are using the AV2 or another component that has a programmable trigger, use the 2.5mm to 3.5mm cable included with the JBL BassQ unit. The remote control will overide the trigger input. 15. Subwoofer Inputs There are two subwoofer inputs. If using an AV1 processor or other processor that has a single subwoofer or LFE output, connect the subwoofer output to the Left input and set the input mode to Mono on the front panel of the JBL BassQ unit. Do not connect the input to the Right input jack, as no signal will be processed. If you are using a preamp/processor such as the AV2, or an AVR that has stereo subwoofer outputs, connect the left and right inputs and set the mode to Stereo on the front panel of the JBL BassQ unit. 16. Subwoofer Outputs There are four subwoofer outputs. These correspond to two subwoofers per side. For best performance, it is recommended that you use at least two subwoofers placed in the front left and front right corners of the room. These would use the L1 (Left 1) and R1 (Right 1) outputs. If four subwoofers are used, the additional subwoofers would be connected to the L2 (Left 2) and R2 (Righ ...
