Removal and Setup
Open the carton and remove foam protective packing from top of package.  
Remove accessory package.  Make sure to locate and store the Owner's 
Manual in a convenient location; this will be needed for operation, and 
subwoofer setup.  Carefully remove AST-SUB10 subwoofer from the factory 
carton and remove from protective plastic bag.  Make sure not to scratch or 
otherwise physically damage your new subwoofer.

To install feet:  make sure the feet (4) have provided locking hex nuts (4) 
threaded to feet prior to installation.  Carefully turn the subwoofer over on 
a side or upside down resting on its top.  This is best done on carpet or 
other non-abrasive soft surface.  Install threaded feet into ¼" receptacle and 
rotate clockwise until screws tighten and feet are in place.  If necessary, use 
provided cushions for the feet to prevent scratching any floor or furniture 
surfaces (i.e.:  hardwood, tile, vinyl / linoleum, or other soft surfaces).  Rotate 
or set subwoofer onto floor making sure all feet (4) are secure and make 
good contact with the flooring surface.  The subwoofer may be leveled by 
adjusting the feet individually.  Secure the feet in position with locking the 
nuts.

To install power cord:  remove power cord from the accessory package and 
undo cord tie to allow full power cord length.  Install cord into AC 
receptacle on rear panel of subwoofer.  You are now ready to read the 
operational and hookup information in the provided Owner's Manual.   

Do not attempt to power up or operate the subwoofer until Owner's Manual 
has been read, consulted, and installation is completed.

Placement Guidelines
Prior to installing your new subwoofer, please consider the following 
guidelines.  Placing the subwoofer near a wall or in a corner will greatly 
increase the overall bass response.   As the frequencies reproduced by 
subwoofers are long and need room to propagate, a subwoofer placed 
away from a wall or corner will not sound as full as when placed in close 
proximity to walls or corners.  Placing close to a wall or corner will enhance 
the projection of the omni-directional bass signal throughout a listening 
environment.

The subwoofer cabinet is designed to blend in and enhance most home 
decors.  The slim, low profile design of the AST-SUB10 subwoofer is intended 
to fit in any room or within normal interior design / furniture applications.  If 
you decide to place anything directly atop your subwoofer, please use great 
caution as the speaker cabinet will vibrate and items place on or near the 
subwoofer may shake loose or fall.  To avoid electric shock and possible 
damage never place anything atop the subwoofer that contains water or 
liquid, such as a hot or cold drink,  vase or flower pot.

Power
There is one main power switch located directly above the AC power cord 
receptacle.  This may be switched ON when necessary for use, and should be 
turned OFF when you plan to be away from home leaving the subwoofer 
unused or idle.  Beneath the main volume control resides the auto off / on 
control switch.  This switch can be set to three operating positions:  ON, OFF, 
and AUTO.  The AUTO position is the default setting.  This keeps the 
subwoofer in standby mode (providing the main power switch is set to 
"ON").  Using sophisticated signal sensing circuitry, the amplifier is 
activated when a signal is detected at either of the inputs.  If no signal is 
detected after several minutes, the amplifier switches back to the standby 
mode.  In OFF mode the subwoofer will be inactive regardless of the main 
power switch setting.  In ON mode the subwoofer will be on and active 
whenever the main power switch is set to the ON position.

Phase
The phase switch is located directly beneath the AUTO ON /OFF switch.  The 
default setting for the phase switch is the 0º position.  As the subwoofer is 
sometimes placed quite a distance from the other speakers, its sound may 
arrive at your ears milliseconds before or after the sound from your other 
speakers.  In the very rare instances where the subwoofer is out of phase, the 
bass will appear somewhat hollow, and the level control may seem to have 
little or no effect.  Setting the phase switch to the 180º position will 
compensate for these effects.  

Note:  Phase is relative, and can be different from location to location.  Always 
return to the normal listening location to evaluate any setting for audible 
changes.
