Using the Low level Thruput

If desired, you can run a low level stereo signal through the 272 PBM THX and out to another unit. This way you can add an additional subwoofer with minimal additional wiring. The signal that comes out of the Thruput jacks is identical to the input signal.

High Level Connection

Alternately, you may use the high level (speaker) inputs. We recommend that you connect your new 272 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. Please consult your audio/video specialist for more specific information.

High level Thruput

If desired, you can run a high level stereo signal through the 272 PBM THX and out to another unit. This way you can add an additional subwoofer with minimal additional wiring. The signal that comes out of the Thruput jacks is identical to the input signal.

You can connect to the High level inputs by using a variety of connectors, or by removing 1/2" of insulation from each wire end, twisting the strands of wire together, placing the wire through one of the post holes and screwing down the nut tightly. It’s 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 will be

marked by either the conductor color, printing on the wire jacket, a ridge on one side of the wire jacket, or a thread intertwined with the wire strands. By convention, the marked wire is connected to the red (+) terminal.

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. Atlantic Technology does not recommend plugging the subwoofer into the switched outlet of an amplifier, preamplifier, or receiver. The power demands of the subwoofer amplifier may exceed the power rating of the switched outlet and may damage the equipment.

The 272 PBM THX is totally automatic in its operation. The automatic on/off circuitry will only activate the subwoofer in the presence of an audio signal from your system. After 7-10 minutes with no signal detected from the rest of the system, the amplifier will shut itself off and go back into standby mode. When the sub is in operating mode, the power LED located under the front grille will glow green. The LED will glow yellow in the Standby mode and power consumption in this mode is negligible. Standby operation can be completely bypassed by placing the Auto/Standby/Bypass switch on the 272 PBM THX amplifier to the Bypass position.

Placement and Operation

Generally speaking, the best location for your new subwoofer is the front of the room, in or close to a corner (Figure 3). Every room has its own unique sound characteristics, and flexibility in the exact placement of the subwoofer is always desirable. The closer the subwoofer is placed to a wall and especially a corner, the more and deeper the bass response you will hear. However, in some rooms, corner placement can produce a “one note” boomy effect. Under such circumstances the subwoofer may work better away from the corner. Experiment to find the best position in your room.
