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.

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.
