Yamaha YST-SW305 - Manual (Page 13)

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 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
STANDBY/ON button to switch the power between ON
and STANDBY 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 STANDBY/ON button).

PHASE switch
Normally this switch is to be set to the REV (reverse)
position. However, according to your speaker systems
or the listening condition, there may be a case when
better sound quality is obtained by setting this switch to
