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.
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 low rumbling noise sequence will be played through the subwoofer system
that sounds like distant thunder. 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
subwoofer 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.
To clear the D.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.
2. Level Setting
Using familiar music or movie material with deep bass content,
adjust the subwoofer level to blend with the other speakers using
your receiver or preamp / processor's subwoofer level control. This
method is more immune to tampering than using the Fathom IWSv2's
"Master Level" knob (think toddlers or curious visitors).
In the unlikely event that the subwoofer level control in your receiver or
preamp/processor cannot be turned up enough to level match the Fathom IWSv2,
return that control to "0". Then, flip the Fathom IWSv2's "Level Mode" switch to
"Variable" and with "0" as your reference point (REF mode gain and Variable "0"
gain are identical) use the "Master Level" control to level match the subwoofer
with the other speakers. MAKE NOTE OF THIS SETTING FOR FUTURE USE.
For more detailed information on your Fathom IWSv2's level setting controls,
please refer to the "Level Mode" and "Master Level Knob" sections on page 14 of
this manual.
3.
Polarity and Phase Adjustment
It is often helpful to have a second person operating these controls so that you
can easily hear the changes from the primary listening seat.
