Dual Subwoofer Placement

When two subwoofers are used, you may wish to place them asymmetri-

OUTPUT

cally; that is, in slightly different positions in the room (Figure 7). This

will reduce common mode room resonances that occur with symmetri-

cally positioned subwoofers. You can also try placing the subwoofers in

L/MONO

the same corner, if you wish. Experiments have shown this to be a viable

means of producing smooth bass response in many rooms.

Using the Low-Pass Crossover Control

LOW-PASS

BYPASS

Many surround sound receivers and processors offer a choice of crossover

settings, typically between 80 Hz and 120 Hz. If yours does, we recom-

mend using the 100Hz setting when using small speakers such as those

in the System 1400 or 2400. Consult your electronics owner's manual

for more details.

Higher crossover frequencies pass more bass to the sub but can sound

boomy and may be more easily localized to the subwoofer. Higher cross-

over frequencies may be suitable, however, when using very small satel-

lites that have no real low frequency performance. Settings lower than

80Hz should be employed if you are using larger speakers that have

extended bass response. This way, the subwoofer will only reproduce the

very lowest bass frequencies that are in the range where the large main

speakers begin to roll off.

It's generally undesirable to have the main speakers and the subwoofer

overlap too much. Larger speakers means a lower Low-Pass crossover

frequency, smaller speakers means a higher Low-Pass crossover fre-

quency. Consult the manufacturer's specified low frequency response

for your main speakers to determine the appropriate Low-Pass setting

on your subwoofer. In the end, however, a little time spent experimenting

will generally result in dramatically better bass response.

particular, there will be a more integrated transition between the satel-

A Word About Bass, Center Channel Modes

and System Set Up

Many surround processors and receivers feature a "Wide" and "Normal"

mode for the center channel speaker. Atlantic Technology recommends

that the center channel be operated in the "Normal" mode when using

a powered subwoofer. The center channel speaker will sound more

dynamic and the intelligibility of the system will generally be improved

when in the "Normal" mode.

With discrete digital systems (Dolby Digital, DTS, etc.) many control-

lers provide a Bass Management option, which lets you set the front and

rear speakers in a limited bandwidth (Small) or full range (Large) mode.

When using a subwoofer with Atlantic Technology speakers we recom-

mend setting such a controller to the Small position for all the speakers

in the system.

Care of Your Subwoofer

The 224 SB, 334 SB and 444 SB are constructed from Medium Density

Fiberboard. MDF is a non-resonant material ideal for speaker system

enclosures. To clean the cabinet you may use a soft cloth either dry or

slightly dampened with clean water. Be careful not to wet the cabinet or

allow any water to enter the cabinet seams. Avoid placing your speakers

in direct sunlight or near a source of heat that may, over time, damage

110-120V

the finish.

IMPORTANT: Save Your Boxes! If you can do so, save the carton,

packing pieces and plastic bags that came with your subwoofer.

They will be useful in case you move or have to ship your sub-

woofer for any reason. In any case, save all packing materials until

you are certain that the system has suffered no damage in ship-

ment. If you find such damage, either visible or internal, contact

50-60Hz 300W MAX

your dealer immediately for the proper return procedure.

FOR 110-120VAC, USE 2.5AL 250V FUSE

FOR 220-240VAC, USE 1.25AL 250V FUSE

Care of your Subwoofer

A subwoofer operating out of phase with the rest of the

STATUS

system won't provide optimum low frequency perfor-

mance. To correct for this, a switch that will reverse the

phase of the subwoofer is provided on the amplifier

panel. Listen to a monaural musical source with strong

bass content. (For example, you can use the mono

switch on an FM tuner or preamp, or use a Y-connector

on the outputs of one of your source components to get

AUTO

a mono signal.)
