OPERATION OF ACTIVE SUBWOOFER
• The SIGNAL IN indicator lights up in amber.
This means that the subwoofer is not disconnected from
the AC mains and a small amount of current is retained to
support the operation readiness.
• To switch the power off, push the POWER switch again.
Then power is cut off and the SIGNAL IN indicator goes
off.
• Depending on the selected mode the subwoofer is turned
on or off as follows :
* ON: The subwoofer is turned on and enters the operating mode.
* AUTO: Only when the signal is being input, it is automatically
turned on to enter the operating mode.
If the signal is not input for more than 10 minutes, it will be
automatically turned off to enter the standby mode.
* OFF: The subwoofer is turned off and enters the standby mode.
Notes :
• Extreme high volume setting may damage your subwoofer.
• Once the volume balance between this subwoofer and
your front speakers is adjusted, you can adjust the volume
of your whole speaker systems by using only the main
unit’s volume control.
• In case of combination of this subwoofer with the supplied
front speakers, because the frequency range of the front
speakers is 140Hz~20kHz, adjust the crossover frequency
to 140Hz or slightly higher.
* The crossover frequency adjustment determines the highest
frequency your subwoofer will reproduce. It allows a seamless
transition from subwoofer to front speakers.
• Normally the PHASE switch is to be set to the “0˚”
(normal)position. However, according to your speaker
systems or the listening condition, there may be a cause
when better sound quality is obtained by setting this switch
to the “180˚”(reverse) position. Select the better position by
monitoring the sound.
• Before operation of main unit, first set the active subwoofer as desired for optimum performance.
Enter the standby mode.
