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 fl at) & 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.
5) Extreme Low Frequency (e.l.f.) Trim
Use the “e.l.f. trim” control to adjust the extreme low bass extension of the
Fathom. Th is control allows -12 dB of cut or +3 dB of boost at 28 Hertz and is
particularly useful when using a Fathom (or two) in a small to medium sized home
theater. Since smaller enclosed spaces help to boost the level of the lowest bass
frequencies, smaller theaters can be overwhelmed by the strong low-bass output of
the Fathom subwoofer. Th
is can create a “thick” or “bloated” character in the lower
bass region. Turning down the “e.l.f. trim” knob cuts the extreme low bass level and
alleviates this condition. Feel free to experiment and listen to a variety of demanding
material until you fi nd the best match for your room and your tastes.
Your Fathom is now optimized for maximum bass performance at your
listening seat. Congratulations!
IMPORTANT! IF YOU MOVE YOUR FATHOM OR PRIMARY LISTENING SEAT
IN THE FUTURE, YOU WILL NEED TO RUN A.R.O. AGAIN. ANY PARTICULAR
CALIBRATION IS UNIQUE TO THAT PARTICULAR SUBWOOFER POSITION
AND LISTENING SEAT POSITION COMBINATION. SIMPLY FOLLOW THE
STEPS ABOVE TO CREATE A NEW CALIBRATION CURVE.
