[. . . ] Frequencies below 20Hz are inaudible and consume vast amounts of amplifier power. Filtering them out with a gradual slope maintains amplifier headroom while maintaining fidelity. Phase inverter toggle switch (0/180°) Allows matching with many systems whose output may be inverse phased. Optical anti-clipping circuitry This is the lowest distortion type of circuit available. It has ideal linearity, works in real time and uses imperceptible time constant triggers (delays) so that its effect during operation, if needed, is virtually instaneous and inaudible. 75°C thermal protection Temperature at external surface of heatsink never goes above 70°C. The output devices are rated to operate safely at much higher temperatures. Auto power on/off function The 7-10 minute turn-off delay features a front panel mounted dual-color LED power indicator for power on and standby indication. 4 q q q q q q q q q q Models 222 PBM, 262 PBM and 352 PBM THX tlantic ATECHNOLOGY q IEC AC power socket Unit comes with a detachable power cord.

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. 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. You can connect your subwoofer by using spade lugs or "banana" 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. Be certain that no stray wire strands are touching across the two terminals as this might damage your amplifier when you turn it on. 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. [. . . ] The center channel speaker will also sound more dynamic and the intelligibility of the system will generally be improved when operated in the "normal" mode. 14 Models 222 PBM, 262 PBM and 352 PBM THX tlantic ATECHNOLOGY Subwoofer Troubleshooting Guide Once your subwoofer has been set up, you should have many years of maintenance free enjoyment from your system. However, if you should encounter a problem, refer to the following guide to help you find the solution. If a problem persists, you should contact your local authorized Atlantic Technology dealer. Problem No bass output Possible Cause AC power cord unplugged or plugged into a non-working outlet. Ground loop through antenna or cable TV system input. Possible Solution Plug into a working outlet.
