Digital Automatic Room Optimization (D.A.R.O.)
A powerful feature of the JL Audio Fathom IWSv2 subwoofers is their innovative
Digital Automatic Room Optimization (D.A.R.O.) technology. This one-touch
system includes 18 bands of digital equalization to eliminate the largest acoustic
response peaks in your home theater at the main listening seat, greatly improving
the in-room low-frequency response. Calibration of the D.A.R.O. system is fully
automated. Please consult the next section of this manual for details on how to use
the D.A.R.O. system.
Using the included JL Audio calibration microphone, the D.A.R.O. calibration
procedure takes less than three minutes. In brief, you will connect the included
microphone to the "Calibration Mic." input, press the Calibrate button, and then
hold the microphone at ear height in your main listening seat during the test. A
noise sequence will be played through the Fathom IWSv2 subwoofer, and the room
response will be automatically measured, analyzed and equalized to eliminate
the single largest acoustic room response peak at your listening seat. For detailed
instructions on the D.A.R.O. setup procedure, refer to pages 29-30.
Calibration Mic. Input
This input is for connecting the supplied JL Audio calibration microphone to the
Fathom IWSv2 subwoofer. Connect one end of the supplied cable to the microphone
and the other end to this jack prior to using the D.A.R.O. system. The D.A.R.O.
system is specifically calibrated to this microphone and its connection scheme is
specific to the supplied microphone. The calibration sequence will not operate when
a different microphone is connected or if no microphone is connected.
Demo Button
The Demo button triggers a 20 second long tone sequence that briefly demonstrates
the sound of the Fathom IWSv2 subwoofer. The Demo function is useful for
showcasing the output capability of the Fathom IWSv2 and to verify that the Fathom
IWSv2 (or multiple Fathom IWSv2s) are operational during system troubleshooting.
The Demo button is also used (in combination) to clear (return to flat) the D.A.R.O.
equalizer settings. To clear the D.A.R.O. settings & 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.
Defeat Button
If "Demo" or "Calibrate" is pressed while the defeat function is active, "Defeat" is
automatically canceled. No other front panel controls will alter the D.A.R.O. Defeat
state. The Fathom IWSv2's Defeat setting is stored in non-volatile memory and will
not change even if power is disconnected.
The Defeat button is also used (in combination) to clear (return to flat) the
D.A.R.O. equalizer settings. To clear the D.A.R.O. settings & 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.
