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!
