Your Acoustic Research Subwoofer delivers powerful, deep bass sound

output for a natural, life-like sonic experience. Please follow the direc-

tions in this manual to achieve the best performance from your system.

The hook-up and operation of the Subwoofer is the same for a Home

Theater surround sound system or a stereo music system.

Subwoofer has its own built-in amplifier, so it works with any sound

system. The Subwoofer's own crossover network sends bass-only

signals to the Subwoofer's built-in amplifier. This lets the Subwoofer add

extra bass to the output from your other speakers.

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.

PLACEMENT

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.

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.

FUSE 250V 3A This fuse protects against

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.

L, R SPEAKER-IN TERMINALS - See Connection Option 1

These terminals are for making connections using speaker wirer. If you

use this option, do not use Option 2.

L,R INPUT JACKS- See Connection Option 2

These jacks are for input connections using audio cables. If your receiv-

er has a mono sub out, you may use either input on your new AR sub-

woofer. If you use this option, do not use Option 1.

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.

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

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.

CONNECTING YOU SUBWOOFER

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

you use 16-gauge speaker wire for hooking your Receiver to your Front

speakers. To make connections to the Subwoofer in parallel with the

Front speakers easier, the speaker wire connecting the Receiver to the

Subwoofer can be smaller (higher gauge number), since the Subwoofer

does not draw large amounts of power through these wires.

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

black-.

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

balance that has plenty of deep bass sound when it is actually

present in the music.

•

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.

Setting the Phase Switch

The PHASE switch controls the phase of the Subwoofers output rela-

tive to that of the Front speakers. In many installations, it will be dif-

ficult to tell which switch setting is the correct one. Listen carefully

to the sound quality while someone else toggles the switch between

its two positions. The position that produces the fullest deep bass

and the warmest bass and mid-bass sound is the correct one. You

may need to readjust the SUBWOOFER OUT LEVEL and SUBWOOFER

CROSSOVER FREQUENCY controls after setting this switch.

TROUBLESHOOTING

Subwoofer POWER Indicator LED does not light

•

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 plug-in a lamp to check it.

•

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.

•

Be sure that the Receiver's Speaker Selector switch is turned on to

the terminals [A or B, 1 or 2] that you have your Front speakers

connected to. If the Receiver has a headphone jack, you can use

headphones to check the Receiver for output.

•

Check the wires and connections from the Receiver's Front Speaker

Output terminals to the Subwoofer's SPEAKER-IN terminals.

•

Try removing the Subwoofer from the system, leaving your Front

speakers connected to the Receiver. If there still is no sound, take

the Receiver to your dealer for service.

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

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.
