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
4) Applying Automatic Room Optimization (A.R.O.)
You are now ready to apply the power of JL Audio’s exclusive Automatic Room Optimization system. This system will measure the response of the subwoofer at your primary listening seat and apply a powerful equalizer to tame the peaks caused by room modes, resulting in smoother, more accurate bass performance. If you are using multiple Fathoms in a master/slave configuration, you will only need to address the unit designated as “master” to perform A.R.O. calibration for the entire subwoofer system. Note that all
a)Set the Main Power switch to the “ON” position and be sure the Fathom’s indicator lights are switched “ON” via the “Lights” switch.
b)Remove the calibration microphone from its protective pouch and connect its cable to the
NOTE: A.R.O. Calibration is only possible when the included JL Audio test microphone is plugged in to the Fathom front panel. The “Calibrate” feature is disabled with no microphone plugged in to prevent accidental loss of settings.
c)Connect the microphone to the other end of the mic cable and temporarily place the mic in the primary listening seat. If you have a microphone stand, you can place the microphone at head height and position in the primary listening seat.
d)On the Fathom’s control panel, press the “Calibrate” button. The green light on the “Calibrate” button will flash slowly, indicating that calibration will begin in 5 seconds.
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 f110 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 f110 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.
