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, 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 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 setting the POWER switch (1) to "ON"). Ⅵ Adjusting the subwoofer before use Before using the subwoofer, adjust the subwoofer to obtain the optimum volume balance between the subwoofer and the main speakers by following the procedures described below.
