Model 162 PBM High Performance Subwoofer
Features
●
Power output rated at 75 watts
Coupled with our highly efficient driver, this subwoofer is capable of surprising
performance.
●
Working frequency range from 20Hz to 150Hz
●
Continuously adjustable low-pass filter from 60Hz to 125Hz
The slope of the low-pass filter is -24 dB/octave. This allows for flexible integration
with most any brand or type of speaker on the market.

The model 162 PBM features stereo inputs and outputs for convenient hookup,
and to provide easy “daisy-chaining” to another subwoofer, if desired.
●
High-level (Speaker Level) inputs and outputs with spring-type connectors
These provide convenient hookup to a sound source that does not have line-level
outputs for a subwoofer.
●
Phase-invert switch (+/-180 degrees)
Allows matching with systems whose output are phase inverted, and to
compensate for unusual room acoustics.
●
Woofer output level control
Matches a wide range of source levels.

Model 162 PBM High
Performance Subwoofer
Introduction
Congratulations on choosing an Atlantic Technology Powered Subwoofer. 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. Study the system diagrams starting on
page 5. Once you have found the example which most closely matches your system,
hook up your subwoofer(s) as shown in that diagram.

tlantic
TECHNOLOGY
Low-Level Connection
For best performance, we suggest using the low-level (RCA style jacks) subwoofer line
out or preamp outputs if your receiver/amplifier has them. Simply connect your
subwoofer with high quality shielded cables as shown in the diagrams.
High-Level Connection
Alternately, you may use the high-level (speaker) inputs. Make sure to match the type
and gauge speaker wire used to connect your main speakers. Be certain that no stray
wire strands are touching across the two terminals as this might damage your amplifier
when you turn it on.
We recommend that you connect your subwoofer using high quality wire of 16 gauge
or larger for lengths up to 25 feet. There are many manufacturers who specialize in
speaker wire and interconnects suitable for your new system. We recommend that you
consult your local audio/video specialist for more specific information.
Warning: To prevent risk of electrical shock or damage to your equipment, always unplug all
component AC cords before proceeding with speaker and component connections.

It is important to observe polarity while making speaker connections: red (+) terminals
on the amplifier to red (+) on the speaker, black (-) on the amplifier to black (-) on the
speaker. Look carefully at the wires you are using and note that one of the wires in each
pair is marked by either a different color, printing, ridges, or a thread intertwined with
the wire strands. By convention, the marked wire is connected to the red (+) terminal.
Voltage Selection
The Atlantic Technology subwoofers operate with either 120 or 240 volts AC 50-60 Hz.
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.

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.

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. It may also harm the finish.
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.
Again, some experimentation will be needed to find the best setting.
Once the controls have been adjusted so that the sound is balanced between the
subwoofer and the main speakers, you can leave them alone. Minor differences in the
source material can be compensated for with the volume and tone controls on your
audio or audio/video electronic components.
Fine Tuning
Atlantic Technology subwoofers integrate easily with virtually all other brands of
loudspeaker. The adjustable low pass filter and versatile hookup options make it a snap.
With proper placement in your room, this subwoofer will supply a solid foundation to
any audio or A/V system.

For best results, we suggest that you “tweak” the controls and cabinet position slightly
over a period of time (1-2 weeks), as you become accustomed to the sound, and have
the opportunity to hear a variety of music and/or movies. Remember that a small
adjustment may have a large overall effect.
