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 SUB10S 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 SUB10S 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.
Using the Controls
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.
