FREQUENTLY ASKED QUESTIONS

Is the Fathom IWS magnetically shielded?

Fathom IWS subwoofers are not magnetically shielded. To avoid magnetic distortion with certain television types, place the Fathom IWS at least 3-4 feet (1 - 1.5m) from your screen.

Will my electric bill be high if I leave the Fathom IWS in “Auto” mode? When in “Auto” mode, the Fathom IWS amplifier is only powered up when a significant signal is detected on the inputs. When powered down, only “housekeeping” circuits remain on, which draw negligible amounts of power from the wall (less than 10 watts).

Should I unplug my subwoofer during a thunderstorm or extended absence? YES. You should unplug your Fathom IWS during (or before) thunderstorms. This will prevent any possible damage from voltage spikes due to lightning. In these conditions, it’s a good idea to unplug all of your audio / video components. If you are going to be away from home for several days, it is also a good idea to unplug your home theater components to prevent damage from unexpected storms or power line conditions.
