• As a general rule, bass response increases as a subwoofer is placed closer to a wall. Therefore, bass output is maximized when the subwoofer is placed in a corner.
• It is also recommended that the subwoofer be positioned along the same wall as the front loudspeakers.
Hookup
When we designed the PSW-D112 powered subwoofer, our goal was to offer the user the best possible performance combined with the most flexi­ble and complete installation options. Please look over the following four examples to determine which description best matches your system and follow the corresponding hookup instructions.
Low-frequency sounds are normally omnidirectional, meaning the listener can’t tell where they are from. However, frequencies between 75Hz – 150Hz can be localized, especially at higher volume levels. Positioning your subwoofer as recommended will provide the most natural soundstage and imaging from your loud­speaker system.
generated
Remember that these are just guidelines. Since every listen­ing room is different, JBL strongly recommends experi­menting with the positioning of your subwoofer to obtain the most pleasing results in your room. One technique that can help you find the ideal
subwoofer location is to tem­porarily place the subwoofer near the main listening loca­tion. Then move room and determine
around the
where you hear the most pleasing bass performance. This would then be the ideal location for the subwoofer.

has subwoofer outputs or preamp output jacks for the left and right channels.
3) If your receiver/amplifier has a single (mono) sub­woofer output or LFE out­put, you may connect the output to either the Left or Right line-level input on the subwoofer. However, to maximize the subwoofer’s performance, we recommend that you
use a “Y”-connector (not included). Plug the single male end of the “Y”-con­nector into the subwoofer output on the receiver/ amplifier, and connect each of the 2 female con­nectors to an RCA-type interconnect cable. Then connect the 2 intercon-
nect cables to the Left and Right line-level inputs on the PSW-D112.
Note: If your receiver/proces­sor contains Dolby* Digital or DTS® surround processing technology, then set the “Low-Pass” control on the 180Hz position.

fier has preamp output jacks and main input jacks for the left and right channels, or you have a separate preamp/ processor and power amplifier.
This method of hookup can offer the highest level of performance for your complete loudspeaker system. The PSW-D112 incorporates a variable high-pass crossover in addition to a variable low-
pass crossover. When hooked up as shown, the subwoofer will limit the low-frequency information that is returned to your receiver/amplifier. Your receiver/amplifier does not need to waste valuable power reproducing the low frequencies. In addition, since no
low-frequency information is being sent to your main loudspeakers, they are able to reproduce mid and high frequencies with greater clarity.

Operation
Power
When the unit is plugged in and power is on and no signal is received, the LED on the front of the unit will turn red. When a signal is present, the LED will turn green. Note: It will take several minutes for the LED to turn from green to red after the input signal to
Crossover Adjustments
Low-Pass Control
The Low-Pass control deter­mines the highest frequency at which the subwoofer reproduces sounds. If your main speakers can comfortably reproduce some low-frequency sounds, set this control to a lower frequency setting, between 50Hz – 100Hz. This will concentrate the subwoofer’s efforts on the ultradeep bass sounds required by today’s films and music. If you are using smaller bookshelf speakers that do not extend to the lower bass frequencies, set the low-pass crossover control to a higher setting, between 120Hz – 180Hz.

power consumption is minimal when the subwoofer is not receiving a signal. Of course, the subwoofer can be turned off, whenever desired.

• If you hooked up your sub­woofer asshown in Hookup 4 on page 5, you also have the capability of adjusting the high-pass frequency. The High-Pass control determines the frequency at which the main speakers will start reproducing sounds. If your main speak­ers can comfortably repro­duce some low-frequency sounds, also set this control to a lower frequency setting, between 50Hz – 100Hz. This will concentrate the subwoofer’s efforts to the ultradeep bass sounds, while your main speakers continue to reproduce the mid-bass information. If you

are using smaller bookshelf speakers that do not extend to
the lower bass frequencies, set the high-pass crossover control to a higher setting, between 125Hz – 180Hz. With this setting, your main speakers will not have the burden of reproducing any low-frequency sounds.
• If you hooked up your sub­woofer as shown in Hookup1 on page 3, the high-pass frequency is fixed at 180Hz.
• If you hooked up your subwoofer as shown in Hookup 2 or Hookup 3 on page 4, no high-pass control adjustments can be made from the subwoofer. Unless your receiver/ampli-

Phase Control
Troubleshooting
The Phase Control determines whether the subwoofer speaker’s piston-like action moves in and out with the main speakers, 0°, or opposite the main speakers, 180°. There is no correct or incorrect set­ting. Proper phase adjustment depends on several variables such as subwoofer placement and listener position. Adjust the phase switch to maximize bass output at the listening position.
Remember, every system, room and listener is different. There are no right or wrong settings; this switch offers the added flexibility to adjust your subwoofer for optimum performance for your specific listening conditions. Should you decide to fine-tune your system for optimum performance, be patient and trust your ears. It will be worth the effort involved to fully “tweak” your system.
If you used the high-level (speaker) inputs and there is no sound from any of the speakers:
• Check that receiver/amplifier is on and a source is playing.
• Check that powered sub­woofer is plugged in.
• Check all wires and connec­tions between receiver/ampli­fier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured.
• Review proper operation of your receiver/amplifier.
If there is low (or no) bass output:
• Make sure the connections to the left and right “Speaker Inputs” have the correct polarity (+ and –).
• Make sure that the sub­woofer is plugged into an active electrical outlet.
• Adjust the crossover point.
• Flip the Phase Control switch to the opposite position.
• If you are using a Dolby* Digital/DTS® receiver or processor, make sure that the subwoofer adjustments on the receiver/processor are set up correctly.
• Slowly turn the Level Control clockwise until you begin to hear the desired amount of bass.
If you used the line-level inputs and there is no sound from the subwoofer:
• Check that receiver/amplifier is on and a source is playing.
• Check that powered sub­woofer is plugged in.
• Check all wires and con­nections between receiver/ amplifier and subwoofer. Make sure all wires are connected. Make sure none of the wires are frayed, cut or punctured.
• Review proper operation of your receiver/amplifier.
• Slowly turn the Level Control clockwise until you begin to hear the desired amount of bass.
• Make sure that you have configured your receiver/ processor so that the sub­woofer/LFE output is on.
