IMPORTANT! MAKE SURE THE ROOM IS QUIET DURING D.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.
4. Applying Digital Automatic Room Optimization (D.A.R.O.)
You are now ready to apply the power of JL Audio's exclusive Digital
Automatic Room Optimization (D.A.R.O.) system. This system will measure the
response of the subwoofer at your primary listening seat and apply a powerful
18-band equalizer to tame the peaks caused by room modes, resulting in
smoother, more accurate bass performance. If you are using multiple Fathom
v2s in a master/slave configuration, you will only need to address the unit
designated as "master" to perform D.A.R.O. calibration for the entire subwoofer
system. Note that all front-panel signal processing is defeated during D.A.R.O.
calibration, regardless of the knob settings. Normal operation is restored once
calibration is complete.
a) Set the Main Power switch to the "ON" position and be sure the Fathom v2'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 mini-XLR jack on the Fathom v2's front control panel.
NOTE: D.A.R.O. Calibration is only possible when the included JL Audio test
microphone is plugged in to the Fathom v2 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 v2'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 Fathom v2 that sounds like hashy
static. The sequence will last approximately 3 minutes. During this process,
the D.A.R.O. system is taking a frequency response measurement at your seat
and correcting the problems it finds. The D.A.R.O. system also compensates
for any before & after level differences so that your Fathom v2 will have a
similar perceived loudness after the calibration process. When D.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.
