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.
IMPORTANT! IF YOU MOVE YOUR GOTHAM v2 OR PRIMARY LISTENING SEAT
IN THE FUTURE, YOU WILL NEED TO RUN D.A.R.O. AGAIN. ANY PARTICULAR
CALIBRATION IS UNIQUE TO THAT PARTICULAR SUBWOOFER POSITION
AND LISTENING SEAT POSITION COMBINATION. SIMPLY FOLLOW THE STEPS
ABOVE TO CREATE A NEW CALIBRATION CURVE.
5. Extreme Low Frequency (e.l.f.) Trim
Use the "e.l.f. trim" control to adjust the extreme low bass extension of the
Gotham v2. This control allows -12 dB of cut or +3 dB of boost at 24 Hertz and
is particularly useful when using a Gotham v2 (or two) in a small to medium
sized home theater. Since smaller enclosed spaces help to boost the level of the
lowest bass frequencies, smaller theaters can be overwhelmed by the strong low-
bass output of the Gotham v2 subwoofer. This can create a "thick" or "bloated"
character in the lower bass region. Turning down the "e.l.f. trim" knob cuts the
extreme low bass level and alleviates this condition. Feel free to experiment and
listen to a variety of demanding material until you find the best match for your
room and your tastes.
Your Gotham v2 is now optimized for maximum bass performance at your
listening seat. Congratulations!
