Applying Automatic Room Optimization A.R.O

IMPORTANT

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.

DO NOT TALK, COUGH OR SNEEZE DURING CALIBRATION AS THIS MAY CORRUPT THE CALIBRATION MEASUREMENTS.

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 primary room mode, 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.

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)Flip the Fathom’s “Level Mode” switch to “Variable” and turn the Master Level control to the “12 o’clock” position. If you were already in “Variable” mode, make a note of the volume position you established during Level Setting (Step 1) before turning it to the “12 o’clock” position for A.R.O. calibration. In most cases, you will need to tweak the overall level of the subwoofer after the A.R.O. calibration is run, but you need to know your prior setting to begin that process.

c)Set the LP Filter to “OFF”

d)Verify that the “e.l.f. trim” control is set to “0”

e)Remove the calibration microphone from its protective pouch

and connect its cable to the mini-XLR jack on the Fathom’s front control panel.

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.

f)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.

g)On the Fathom’s control panel, press the “Calibrate” button. The green light on the “Calibrate” button will turn on, indicating that calibration will begin in 5 seconds.

NOTE: If you have already run A.R.O. once, the “Calibrate” light will already be on. Each time A.R.O. calibration is run, the previous settings are erased and the new settings are stored.
