The bracket for the AST 220S and AST 220C has a
“Center Line” stamped into it, and indicates where the
center of the speaker will be located when mounted onto
the bracket. Use this “Center Line” to locate the brackets
vertically For the AST 220S loudspeakers and horizon-
tally for the AST 220 C.
By drawing horizontal and vertical center lines through
the area covered by the display you can use the “Center
Line” of the brackets to properly center the speakers on
the display in the horizontal and vertical planes. Use a
level to keep the vertical brackets plumb and the horizon-
tal bracket level.

Assembling the Base to the AST 220S
To attach the “Base” to the AST 220S, use a Phillips head
screwdriver to remove the four screws from the bottom end
cap of the AST 220S speaker.
Note: If the screws do not
seem to align properly with
the four channels of the
aluminum extrusion of the
AST 220S, loosen the four
Pan Head screws that retain
the steel plate to the bottom
of the “Base”. (Do not remove
these screws.) Re-align the
base of the extrusion and
tighten all screws. Be careful
not to overtighten the screws
and possibly strip the channel
to the point the screws will
not grip snugly.
Assembling the AST-Stands
If you wish to use a pair of the AST 220S speakers as floor
standing speakers, they can be mounted to the
AST-Stands in the following manner.
Mount the supplied bases to the AST-Stands as described
in the section above “Assembling the Base to the
AST 220S”.
Next, remove the four screws from the bottom end cap of
the AST 220S speaker, set the end cap and four screws
aside. Please retain these parts for possible use later.
Next, insert the 1.5” x 9” metal
support into the channel on
the rear or the AST-Stand,
and attach to the AST-Stand
with two of the four supplied
screws.
Find a pair of wires with slide-on connectors loose in
the bottom of the AST 220S. These will mate with the two
wires extending from the AST-Stands.
Place the open end of the speaker into the base. Replace
the four screws into the AST 220S. Start all for screws
before fully tightening.
