High Performance THX Powered Subwoofer System
Congratulations on your purchase of an Atlantic Technology 372 PBM THX powered subwoofer. With
proper care, your new subwoofer will provide many years of trouble-free, high quality reproduction.
The 372 PBM is fully THX certified to provide very high output levels and a wide dynamic range with
smooth in-room response down to 20 Hz, with a peak SPL of 108 dB.
The subwoofer also features a proprietary class G linear amplifier conservatively rated at 275 watts rms.
This amplifier, coupled with a massive 15" high-excursion woofer will deliver very high output levels
with minimum distortion.
Your Atlantic Technology powered subwoofer will easily integrate with virtually all other brands of
loudspeakers on the market. All inputs and outputs, both line level and high (speaker) level, are
designed for optimum signal integrity. The premium quality gold plated connectors and all controls
are clearly labeled and versatile in operation. The amplifier has more than ample power and headroom
to supply a high fidelity foundation to any audio or home theater system.

environment is transformed into the large acoustic space of a real theater. It’s really quite startling how

soundtrack mixed and equalized to play back in a large theater to
reproduce naturally when you experience the film at home.
It is important to realize that THX is not a recording process or a
special decoding system. All motion pictures will be reproduced as
they were heard in the film studio dubbing stage through the Home

Connection
● Adjustable low-pass filter from 55 Hz to full bypass
The slope of this low-pass filter is 18 dB/octave. This allows for flexible integration with most any
brand or type of speaker on the market. A subsonic filter is also incorporated to filter out
inaudible frequencies that can rob amplifier power.
● Two line inputs, two line thruputs, and an 80 Hz line level output
The thruputs allow daisy-chaining of multiple subwoofers, or can act as a return path back to the
processor. The high-pass outputs send the audio signal, minus the bass frequencies below 80Hz,
back to your amplifier and main speakers.
● Phase inverter toggle switch (0/180 degrees)
Allows matching with many systems whose output may be inverse phased.
● Front panel variable volume control with THX bypass position
● Automatic standby operation
The 7-10 minute turn-off delay features a front panel indicator and a defeat switch.
● IEC AC power socket
Unit comes supplied with a detachable power cord.
● Heavy duty rocker type power switch
● Design and construction meets all UL/CSA European safety requirements
The Atlantic Technology 372 PBM THX Powered Subwoofer is 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 simplicity, 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.
We recommend that you connect your new 372 PBM THX Powered Subwoofer(s) using high quality
wire of 16 gauge or larger. There are many respected manufacturers in the audio industry that
specialize in speaker wire and interconnect cables 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! The last step in wiring your system is
plugging in the AC cords!
