Your Acoustic Research Subwoofer delivers powerful, deep bass sound output for a natural,
The
For simplicity, we call your Home Theater system’s or music system’s main speakers the Front speakers. We call your AV receiver, stereo receiver, or integrated amplifier the Receiver.
LOW PASS FREQUENCY CONTROL Adjusts the upper frequency limit for audio signals going to the Subwoofer amplifier. This control helps you adjust the systems tonal balance.
LEVEL CONTROL Balances the loudness of the Subwoofer relative to the Front speakers and compensates for room effects on the Subwoofer’s output.
PHASE SWITCH The Phase Switch controls the phase of the Subwoofer’s output relative to the front speakers. Listen carefully to the sound quality while playing a CD with low bass. Select the position of the switch that produces the fullest deep bass without boominess. You may need to readjust the Level and Low Pass Frequency controls after setting the Phase Switch.
SUBWOOFER ADJUSTMENT & USE
Subwoofer initial control settings
•Set the LOW PASS FREQUENCY Control to its center position.
•Set the LEVEL Control fully counterclockwise to MIN. You’ll reset this control after you make other adjustments.
Adjusting the Subwoofer controls
• | Play a program on your system. For the following adjustments, use |
| the Dolby ProLogic Normal surround mode and select a movie that |
| has a Dolby Surround soundtrack with a lot of music, or play a music |
| CD. Adjust the Receiver’s volume control for a comfortable sound |
| level from the system speakers. |
• | Increase the Subwoofer’s LEVEL Control setting clockwise, so that |
| you hear the deep bass. Adjust the control for a natural, musical |
program with plenty of bass, such as jazz or rock music, or an action movie.
•If everything else checks OK, take the Subwoofer to your dealer for service - THERE ARE NO USER SERVICEABLE PARTS INSIDE.

Your AR subwoofer should be placed on the floor.You should be aware that the closer the subwoofer is placed to the wall,the more pronounced the bass will become,with maximum bass being achieved with the sub- woofer being placed in a corner.
To optimize you system's electronic components,try and keep all speaker wire and cables as short as possible.
SUBWOOFER CONTROLS & CONNECTIONS
IMPORTANT When you make connections. make sure that the power switches of all components, including the Subwoofer, are OFF.
AUDIO CABLES If you are connecting the Subwoofer into a system made up of separate components (preamp & power amps), you will need audio cables long enough to reach the Subwoofer from the preamplifier and the power amplifier.
SPEAKER WIRE Typical speaker wire has a pair of separate conductors with insulating jackets that are molded together. We recommend that
• | Listen carefully to bass voices and, if needed, adjust the LOW PASS |
| FREQUENCY Control so that they sound natural. Setting the |
| frequency too high will make deep voices sound excessively |
| “chesty” or resonant and will give the upper bass in music a “one- |
| note” quality. Setting the frequency too low will make deep voices |
| sound “thin” and will give music a lack of “warmth”. |
• | Make fine adjustments until the program has satisfying and natural |
| sound quality on both bass voices and music. |

POWER INDICATOR LED Your AR Subwoofer has 2 LED indicators. The Power LED indicator is located on the amplifier on the rear. This LED is unlit when the AC power switch is OFF. It glows red when the Subwoofer is in standby mode and green when the Subwoofer is on. The Signal indicator LED is Blue and is located next to the AR logo on the front of the sub- woofer. This LED is lit when there is an audio signal present.

BARE WIRE |
POLARITY All speakers in a system must be connected with the same polarity. Speaker wire is marked for polarity so that you can identify which wire in the pair is which. Polarity is shown by a color strip on the insulation, by ridged molded into the insulation, or by the colors of the wires - one copper and one silver.
Strip the insulation from speaker wire ends to reveal the bare conductors before connecting to Receiver, Subwoofer or Speaker terminals.
IMPORTANT Always connect the red + terminal on the Receiver to the red + terminal on the Subwoofer, and the black - terminal on the Receiver to the black - terminal on the Subwoofer. The same is true for hooking the Receiver outputs to the Front speakers: red + to red +, and black- to
FUSE 250V 3A This fuse protects against internal and external faults. If the POWER switch is ON and the power indicator LED is
unlit, unplug the power cord from the AC outlet and check the fuse by unscrewing the center piece from the holder. IMPORTANT If the fuse is blown, replace it only with a fuse of the same type and current rating.
IMPORTANT USE OPTION 1 OR OPTION 2, NOT BOTH. OPTION 1 – CONNECTION WITH SPEAKER WIRE
may need to readjust the SUBWOOFER OUT LEVEL and SUBWOOFER CROSSOVER FREQUENCY controls after setting this switch.
TROUBLESHOOTING

•Check that the Subwoofer’s POWER Switch is in the AUTO ON position.
•If the POWER Switch is in the AUTO ON position, check the AC out let the Subwoofer is plugged into to be sure that it is live. You can use a tester or
•If the AC outlet is live, either the power cord or Subwoofer has a problem. Unplug the power cord from the AC outlet and check the fuse by unscrewing the center piece from the holder. If it is blown, replace the fuse only with a fuse of the same type and rating. If this doesn’t help, take the Subwoofer to your dealer for service – THERE ARE NO USER SERVICEABLE PARTS INSIDE.
No sound from the Front speakers.
• | Be sure the Receiver and Subwoofer POWER Switches are in the On |
| positions. |
• | Check the Receiver’s Volume Control Setting - if it is all the way |
| down, there won’t be any sound. |
• | Check that the Receiver’s Input Selector is set to an active source of |
| audio signals and that a Tape Monitor Loop is not engaged. |

LFE INPUT JACK- Allows direct connection from the amplifier/processor with an internal low pass filter. This connection bypasses the subwoofer internal crossover circuitry. Use only with appropriate Surround Sound processor/amplifier.
LFE Output Jack This connector is connected internally to the LFE input jack and allows you to loop the LFE input signal out to another LFE input on an additional AR powered loudspeaker or subwoofer.
SUBWOOFER
Connect speaker wires from the Receiver’s front left and right speaker outputs to the subwoofer’s left and right Speaker In terminals, as well as the left and right front speakers.
No sound from the Subwoofer
•First, be sure there is sound from the Front speakers and that the Receiver is working correctly as outlined above.
•Check the Subwoofer’s LEVEL Control. If it is all the way counter clockwise, there may be no sound.
•The Subwoofer only reproduces deep bass sound. If the program has no deep bass, the Subwoofer will not make any sound. Play a
