When using an AV receiver and the LFE input, set the subwoofer calibration
level to the factory setting, and select LFE for CROSSOVER.
1.
Ensure that the subwoofer is plugged in.
During initial setup, set the POWER CONTROL to FRONT PANEL. Once calibration
is complete, switch to AUDIO SENSE to enable the automatic power-saving mode.
For reference, the different modes are as follows:
FRONT PANEL:
Always on. Amplifier does not turn off automatically. Turn the unit
ON/OFF using the front panel power button.
12V TRIGGER:
Amplifier turns on when 12V signal is detected and off when 12V
signal is absent.
AUDIO SENSE:
Audio Sense enabled. Amplifier turns on when audio signal is
detected. Unit enters standby mode if no signal is detected after 15 minutes.
2.
Select the desired EQ setting or set to FLAT (unmodified sound). Set the
