JL Audio f110 owner manual Extreme Low Frequency e.l.f. Trim

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.

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.

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!
