Fathom IWS

IMPORTANT

IMPORTANT! MAKE SURE THE ROOM IS QUIET DURING A.R.O. CALIBRATION! TURN OFF ANY NOISY APPLIANCES NEAR THE LISTENING ROOM (DISHWASHERS, WASHING MACHINES, ETC.)

IT IS PARTICULARLY IMPORTANT TO TURN OFF AIR CONDITIONERS OR HEAT PUMPS DURING CALIBRATION. THESE FORCED-AIR-TYPE HVAC SYSTEMS CAN CREATE MODERATE LEVELS OF 15 – 20 HZ NOISE THAT MAY INTERFERE WITH CALIBRATION.

e)Within 5 seconds of pressing the “Calibrate” button, return to your primary listening seat and hold the microphone in your normal, seated head position at the approximate height of your ears.

f)A noise sequence will be played through the Fathom IWS that sounds like hashy static (like when your old FM radio was between stations). The sequence will last approximately 3 minutes. During this process, the A.R.O. system is taking a frequency response measurement at your seat and correcting the problems it finds. The A.R.O. system also compensates for any before & after level differences so that your subwoofer will have a similar perceived loudness after the calibration process. When A.R.O. is finished calibrating, the “Calibrate” button will light and stay on, indicating a successful calibration.

Should you wish to run a new calibration, simply repeat the steps above.

To clear the A.R.O.’s settings (i.e., return them to flat) & turn off the Calibrate light, press and hold the Demo button and then press the Defeat button. Please note that you must perform this button sequence quickly. If you hold the Demo button for more than 2 seconds without touching the Defeat button, the Demo tones will start. Should this happen, simply wait for the Demo sequence to end and try again. You can perform a new calibration by following the normal procedure outlined above.

2) Level Setting

Using familiar music or movie material with deep bass content, adjust the subwoofer level to blend with the other speakers using your receiver or preamp / processor’s subwoofer level control. This method is more immune to tampering than using the Fathom IWS’s “Master Level” knob (think toddlers or curious visitors).

In the unlikely event that the subwoofer level control in your receiver or preamp/processor cannot be turned up enough to level match the Fathom IWS, return that control to “0”. Then, flip the Fathom IWS’s “Level Mode” switch to “Variable” and with “0” as your reference point (REF mode gain and Variable “0” gain are identical) use the “Master Level” control to level match the subwoofer with the other speakers. MAKE NOTE OF THIS SETTING FOR FUTURE USE.

For more detailed information on your Fathom IWS’s level setting controls, please refer to the “Level Mode” and “Master Level” sections on pages 15 - 16 of this manual.
