Demo Button
The Demo button triggers a 20 second long tone sequence that briefly
demonstrates the range of the Gotham v2 subwoofer. The Demo function is useful
for showcasing the output capability of the Gotham v2 and to verify that the Gotham
v2 (or multiple Gotham v2s) 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.'s 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 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.'s 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.
Calibrate Button
During the D.A.R.O. test sequence, the Calibrate button's green LED will blink
quickly to alert the user to two special conditions:
1. "JL Audio Microphone NOT Connected": If you forget to connect the mic
before trying to start a Calibration you will get this alert. Press the Calibrate button
once to cancel the alert, connect the D.A.R.O. microphone, and try again.
2. "Inappropriate Sound Level for D.A.R.O. Calibration": Since the D.A.R.O.
sequence is completely automatic, this alert likely indicates a problem with the
microphone. Press the Calibrate button once to cancel the alert. Ensure that the JL
Audio microphone is properly connected and try again. For further help, please refer
to Troubleshooting on page 33.
Input Mode Indicators
The Input Mode indicator LEDs show the input mode, either "Master" or "Slave",
selected by the switch on the Gotham v2's back panel (unless the "Lights" switch is
set to "off"). For further details, see page 20.
Level Mode
The two-position Level Mode switch allows you to select between the following
modes:
"Reference": In this mode, the Master Level control knob has no effect on the
Gotham v2's output level. Use this setting if you will primarily be controlling the
subwoofer level via your receiver or preamplifier/processor. For those of us with
small children or overenthusiastic teenagers, this mode of operation will prevent
direct manipulation of the Master Level.
"Variable": In this mode, the Master Level control knob determines the output
level of the Gotham v2 subwoofer. This mode is also useful when level matching the
Gotham v2 subwoofer to a pair of stereo speakers in a two-channel system.
