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.

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.

●

Auto-standby function with dual-color power indicator

The 10 minute turn-off delay features a green/yellow LED for power on and

standby status indication.

●

IEC AC power socket, with detachable power cord

You can easily replace this cord with one of another length, plug style, etc.

●

120/240V AC input externally switchable, with external fuse holder

You can use it virtually anywhere and not worry about the wrong voltage.

●

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.

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 perfor-

mance 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 sub-

woofer 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 empha-

size 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.
