The AudioSource AST 220S and AST 220C were specifically designed for use in a Home Theater system. Additionally, this speaker system has been optimized to enhance the total theater experience with flat panel displays such as Plasma, LCD and DLP Projection and Rear Projection displays.

The AST 220S is designed to be used as the satellite speakers; left and right front as well as left and right side or rear speakers. They are designed to be wall mounted using the supplied brackets or they can be set up to be table mounted utilizing the supplied bases. One pair may be set up to be floor standing using the stands provided.

The AST 220C is the specifically designed for use as the front center channel speaker and can be mounted to the wall beneath the display using the mounting bracket provided or it may be table mounted on any flat surface using the Isolation Mounting Feet included with the AST 220C. These feet were custom molded to fit the bottom edge of the AST 220C and should be placed near either end in a manner that is aesthetically pleasing to the user. The molded surface has an adhesive layer that can be exposed by removing the protective paper layer once you have determined the placement of the feet for your intended use.

Placement of the Brackets

The placement of the brackets for the left and right front loudspeakers should considered from the point of making the loudspeakers perform correct acoustically while maintaining an aesthetically pleasing appearance. The AST 220S has very wide dispersion characteristics in the horizontal plane. Therefore, the AST 220S loudspeakers may be mounted in close proximity to your display or screen area. We recommend that you leave a minimum of 2 to 3 inches between the edge of the display or screen area.

If you wish to extend the speakers beyond the 2” to 3” minimum that presents no problem. Please note that the distance between the right and left speakers should not be greater than the distance from the speakers to the listener’s position.

Mounting the Wall Brackets

The wall mounting brackets are designed to be attached to the wall surface using screws. Where no underlying wall stud is available for proper placement it is highly recommended that an appropriate wall anchor be used.

We do not recommend a particular type since many different wall surfaces may be encountered. If you are unsure as to which type of wall anchor to use consult with your local Hardware or Do-It-Yourself store specialist to determine the correct anchor for the type of wall surface in your home. Note: the weight of an AST 220S or an AST 220C is 7.1 pounds.

The wall mounting bracket has four slots to accept screws for attaching it to the wall surface. If you are locating the bracket over a wall stud these slots will fall within the width of a standard 2x4 or 2x6 wall stud. There is a slot at the bottom and in the middle of the bracket to allow the speaker cable to be brought through both the wall and the bracket to connect to the terminals on the rear of

the AST 220S and the AST 220C loudspeakers.
