POLARITY Menu
The Polarity menu is used to change the polarity of the subwoofer system. Available options
for this selection are: NORMAL and REVERSE.
▪ NORMAL – A positive signal into the subwoofer produces a positive sound pressure.
(Default)
▪ REVERSE – A positive signal into the subwoofer produces a negative sound pressure.
Notice!
If one (1) subwoofer is set to NORMAL and another subwoofer is set to REVERSE, the output
of the subwoofers cancels acoustically.
Ensure all subwoofers in a system are set to the same polarity of the output so the
subwoofers sum properly. Under most circumstances, the polarity of the subwoofer should
be set to NORMAL.
OPTIONS Menu
The Options menu is used to configure the DSP menu, LCD screen, and system. You can also
configure the accessibility of the menu as well as reset the modified settings to factory
default.
BACK Menu
The Back menu is used to return to the main menu.
FRONT LIGHT Menu
The Front Light menu shows power on and indicates limit. Available options for this selection
are: ON, OFF or LIMIT.
▪ ON – turns the LED on when the power to the loudspeaker is ON. (Default)
▪ OFF – turns the LED off.
LIMIT – turns the LED off under normal operation. The LED brief blinking indicates the power
amplifier is operated at its limits. Short-term blinking is not critical because the integrated
limiter keeps distortion under control. Constant lighting of the LED indicates the sound is
negatively affected. Reducing the output volume is strongly recommended. For more
information see, System status, page 27.
MEASUREMENT Menu
The Measurement menu is used to select the unit of measure for the delay. Available options
for this selection are: METERS or FEET.
The default is METERS.
DISPLAY BRIGHTNESS Menu

+10.
The default is zero (0).
DIM DISPLAY Menu
The Dim Display menu is used to dim the display when the display is idle for two (2) minutes.
Available options for this selection are: ON or OFF.
