Our subwoofers feature proprietary amplifiers and special high excursion woofers. The sealed acoustic suspension cabinet configuration provides extended, tight, deep bass in a compact, room-friendly design. Connection Atlantic Technology Powered Subwoofers are simple to hook up, offering several connection methods for maximum flexibility. [. . . ] Please make sure that the voltage selector switch shows the correct voltage for your area before plugging the unit in. The voltage can be easily changed by moving the switch to the correct voltage in your area and installing the proper fuse and power cord. To change the fuse, remove the power cord, insert a screwdriver tip into the notch in the side of the fuseholder, and pry the fuse out. Replace with the correct value fuse as marked next to the fuseholder, and push back into place. 6 Model 162 PBM High Performance Subwoofer tlantic ATECHNOLOGY Power Connection Connect the power cord to an AC outlet only after making all other connections to the subwoofer. This will avoid any chance of accidentally activating the subwoofer while wiring. The AC cord should be plugged into its own wall outlet or into a quality power strip. Avoid using the outlets that are provided on the rear panel of other components. The subwoofer may require more current than these outlets can provide and performance may suffer. Once the subwoofer is hooked up and the power cord is plugged into an AC outlet, leave it plugged in. Automatic on/off circuitry will activate the subwoofer in the presence of an audio signal. After 8-10 minutes with no signal detected, the amplifier will go into standby mode. There is no need to unplug the subwoofer or use a switched outlet. Placement and Adjustment This subwoofer's compact size allows easy placement for optimum performance. As a general rule, corner placement gives the loudest bass output, but may tend to emphasize one particular frequency. Moving the subwoofer away from the wall results in flatter frequency response, but will reduce the output somewhat. Experiment with several different positions to find the best one for your room.

Start here Less Bass More Bass 7 Model 162 PBM High Performance Subwoofer tlantic ATECHNOLOGY Note: Do not place the unit near a heater or forced air outlet, as this may impair the ability of the internal amplifier to dissipate heat. When you're setting things up for the first time, you will need to adjust the bass level control to keep the bass volume the same for various subwoofer positions. The only way that you can make sure that you're not being impressed by more bass, instead of smoother bass, is to keep the volume the same for all subwoofer positions. Begin with the low pass control set to 80, adjusting a little at a time to give the smoothest transition between the subwoofer and the main speakers as, for example, a bass guitar or cello is played up and down the scale. Try both positions of the phase invert switch, as unusual room acoustics may be present at the crossover frequency. [. . . ] Single HI LEVEL input connected to the RIGHT channel. Ground loop through antenna or cable TV system input. OUTPUT LEVEL CONTROL set too low. Possible Solution Plug into a working outlet. Check all connections, then try another input cable. [. . . ]
