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 operates by sensing a certain level of low
frequency input signal. Usually set the AUTO STANDBY
switch to the LOW position. However, if this function does
not operate 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.
