Turn on your entire audio system and start a CD or movie soundtrack at a moderate level. Auto On/Standby With the Power Switch 5 in the ON position, the Status LED on the top will remain lit in red or green to indicate the On/Standby mode of the subwoofer. RED = STANDBY (No signal detected, Amp Off) GREEN = ON (Signal detected, Amp On) The subwoofer will automatically enter the Standby mode after approximately 10 minutes when no signal is detected from your system. The subwoofer will then power ON instantly when a signal is detected. During periods of normal use, the Power Switch 5 can be left on. You may turn off the Power Switch 5 for extended periods of nonoperation, e. g. , when you are away on vacation. Adjust Gain Turn your Subwoofer-Level Control 2 up to the halfway position. If no sound emanates from the subwoofer, check the AC-line cord and input cables. Are the connectors on the cables making proper contact?Is the AC plug connected to a "live" receptacle?Has the Power Switch 5 been pressed to the "On" position?Once you have confirmed that the subwoofer is active, proceed by playing a CD, record or cassette. Use a selection that has ample bass information. Set the overall volume control of the preamplifier or stereo to a comfortable level. Adjust the Subwoofer-Level Control 2 until you obtain a pleasing blend of bass. Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range.
