Automatic power-switching function
If the source being played is stopped and the input signal
is cut off for 7 to 8 minutes, the subwoofer automatically
switches to the standby mode. (When the subwoofer
switches to the standby mode by the automatic power-
switching function, the power indicator lights up in red.)
When you play a source again, the power of the
subwoofer turns on automatically by sensing audio signals
input to the subwoofer.
This function will operate by sensing a certain level of low
frequency input signal. Usually set the AUTO STANDBY
switch to the LOW position. However, if the power is not
switched to ON or STANDBY smoothly, set the switch to
the HIGH position. In the HIGH position, the power will
turn on even with a low level of input signal. But please be
aware that the subwoofer may not switch to the standby
mode when there is an extremely low input signal. * The power might turn on unexpectedly by sensing noise
from other appliances. If that occurs, set the AUTO
STANDBY switch to the OFF position and use the
POWER switch to switch the power between ON and
OFF manually.
* This function detects the low-frequency components
below 200 Hz of the input signals (i.e., the explosion in
the action movie, the sound of the bass guitar or the
bass drum, etc.).
* The minutes required to switch the subwoofer to the
standby mode might change by sensing noise from
other appliances.
This function is available only when the power of the
subwoofer is on (by pressing the POWER switch).
